abstract

The spread of false information has posed a considerable threat to public health and the successful control of global epidemics. Studies have found that exposure to false information may reduce the willingness to vaccinate and comply with public health guidelines. The recent review paper of Nature Medicine summarizes three key directions of information Infodemic: susceptibility, transmission and immunity. Existing research has evaluated the following three questions: why some people are more susceptible to false information, how false information spreads in online social networks, and what intervention measures can help improve psychological immunity to false information. This paper discusses the significance of existing research to stop the information epidemic.

Introduction to false information research

At the beginning of 2020, the World Health Organization (WHO) announced that the world was falling into an information Infodemic. The information epidemic is characterized by information overload, especially full of false and misleading information. Although researchers have discussed the impact of fake news on major social events (such as political elections), the spread of false information is more likely to cause significant harm to public health, especially during the COVID-19 pandemic. For example, studies in different countries/regions show that supporting COVID-19’s false information is closely related to people’s unwillingness to follow public health guidelines [4,5,6,7], reduce vaccination and recommend vaccines to others. Experimental evidence shows that exposure to false information about vaccination will reduce the willingness of those who claim that they "will definitely accept the vaccine" by about 6%, thus weakening the group immune potential of the vaccine [8]. The analysis of social network data estimates that if there is no intervention, anti-vaccination content on social platforms such as Facebook will dominate in the next decade. Other studies have found that exposure to false information about COVID-19 is related to the increased tendency to ingest harmful substances and participate in violence. Of course, long before the COVID-19 pandemic, false information had already posed a threat to public health. The connection between the exposed MMR vaccine and autism is related to the significant decline in vaccination coverage in the UK. Listerine manufacturers lied that their mouthwash can cure the common cold for decades.False information about tobacco products has influenced people’s attitudes towards smoking. In 2014, the Ebola clinic in Liberia was attacked because people mistakenly thought that the virus was part of a government conspiracy.

In view of the unprecedented scale and speed of the spread of false information on the Internet, researchers are increasingly relying on epidemiological models to understand the spread of false news. In these models, the key focus is the reproductive number (R0)-in other words, the number of people who start publishing fake news (i.e. regenerative cases) after contacting people who have published false information (infectious individuals). Therefore, it is helpful to imagine false information as a viral pathogen, which can infect the host and spread rapidly from one person to another in a given network without physical contact. One advantage of this epidemiological method is that an early detection system can be designed to identify super communicators, so that intervention measures can be deployed in time to curb the spread of viral false information [18].

This review will provide readers with a conceptual overview of the latest literature on false information and a research agenda (Box 1), which includes three main theoretical dimensions consistent with virus analogy: susceptibility, transmission and immunity.

Box1 Future research agenda and suggestions

Research question 1: What factors make people easily misled by false information?

Better combine the accuracy drive with social, political and cultural motives to explain people’s susceptibility to wrong information.

Define, develop and validate standardized tools for assessing susceptibility to false information in general and specific fields.

Research Question 2: How does false information spread in social networks?

Draw a clearer outline of the conditions to what extent "exposure" leads to "infection", including the influence of repeated exposure, the positioning of local audience of fake news on social media, the contact with super communicators, the role of echo chamber, and the structure of social network itself.

By (1) capturing more different types of false information, and (2) linking different types of fake news risks on traditional and social media platforms, we can provide more accurate risk estimation of false information exposure at the population level.

Research question 3: Can we take measures for people or protect them from false information?

Focus on evaluating the relative effectiveness of different debunking methods in this field, and how to combine debunking (therapeutic) with preventive intervention measures to maximize its protection performance.

Modeling and evaluating how psychological inoculation (intervention) methods spread on the Internet and affect the sharing behavior on social media and in the real world.

Before reviewing the existing literature to help answer these questions, it is necessary to briefly discuss the meaning of the word "misinformation", because inconsistent definitions not only affect the conceptualization of research design, but also affect the nature and effectiveness of key outcome measurement. In fact, false information is called an all-encompassing concept [20], not only because of different definitions, but also because the behavioral consequences to public health may vary according to the types of false information. The word "fake news" is often considered problematic because it does not fully describe all kinds of false information, and it has become a politicized rhetorical device. Box 2 discusses the different academic definitions of false information in more detail, but for the purpose of this review, I will simply define false information in the broadest possible sense: "false or misleading information disguised as legitimate news", regardless of its intention. Although false information is usually different from false information, because it involves obvious intention to deceive or hurt others, and the intention may be difficult to determine, so in this review, my handling of false information will cover both intentional and unintentional forms of false information.

The Challenge of Box2 in Defining and Manipulating False Information

One of the most frequently cited definitions of false information is "fabricated information that imitates the content of news media in form, but does not imitate it in organizational process or intention" [119]. This definition means that the important factor that determines whether a story is false information is the news or editing process. Other definitions also reflect similar views, that is, producers of false information do not abide by editing norms, and the defining attribute of "falsity" occurs at the publisher level, not at the story level. However, others hold a completely different view, and they define false information either from the perspective of the authenticity of the content or from the perspective of whether there are common technologies used to make the content [109].

It can be said that some definitions are too narrow, because news reports do not need to be completely wrong to be misleading. A very prominent example comes from the Chicago Tribune, a widely trusted media, which republished an article entitled "A healthy doctor died two weeks after COVID-19 vaccine injection" in January 2021. This story will not be classified as false because of its source or content, because these events are true when considered separately. However, at the time of publication, there is no evidence to prove this causal relationship, so it is extremely misleading and even considered immoral to think that the doctor died because he was injected with COVID-19 vaccine. This is an unremarkable example. In early 2021, it was viewed more than 50 million times on Facebook [121].

Another potential challenge to the definition based on content is that when the consensus of experts on a public health problem is rapidly formed and influenced by uncertainty and change, the definition of what may be true or false may change over time, making the oversimplified classification of "true" and "false" a potentially unstable attribute. For example, although the news media initially claimed that ibuprofen would add symptoms of re-crown, this statement was later withdrawn as more evidence appeared. The problem is that researchers often ask people whether they can accurately or reliably identify a series of true or false news headlines, which are either created by researchers according to different definitions of false information or screened by them.

There are also differences in the measurement of the results; Sometimes, the relevant result measurement standard is the susceptibility of false information, and sometimes it is the difference between true and false news detection, or the so-called "truth recognition". The only existing tool to use the title set verified by psychometrics is the recent "false information susceptibility test", which is a measurement method for news authenticity recognition and standardized according to the test group. On the whole, this means that hundreds of new special studies on false information are emerging, and the results are not standardized and not always easy to compare.

I. Susceptibility

Although people use many cognitive heuristics to judge the truth of a claim (for example, the credibility of the perceived source), there is a particularly prominent discovery that can help explain why people are easily influenced by false information. This discovery is called the "illusory truth effect": repeated assertions are more likely to be judged as true than non-repeated (or novel) assertions. Because mass media, politicians and social media influencers often repeat many false facts, the credibility of illusory truth has greatly increased. For example, the conspiracy theory that Covid-19 was made by bioengineering in a military laboratory in Wuhan, China, and the false statement that "COVID-19 is no worse than the flu" have repeatedly appeared in the media. People tend to think that repeated claims are correct. The main cognitive mechanism is called processing fluency: the more a claim is repeated, the more familiar it becomes and the easier it is to deal with. In other words, the brain uses fluency as a signal to show the truth. The research shows that: (1) prior contact with fake news will increase its perceived accuracy; (2) For specious claims, illusory truth may appear; (3) Transcendental knowledge may not protect people from illusory truth; (4) Unreal truth does not seem to be influenced by the way of thinking, such as analytical or intuitive reasoning.

Although illusory truth can affect everyone, research shows that some people are still more susceptible to false information than others. For example, some common findings include the observation that the elderly are more susceptible to fake news, which may be caused by factors such as cognitive decline and unfamiliarity with digital technology, although there are exceptions: facing COVID-19, the elderly seem unlikely to recognize false information. Those with more extreme and right-wing political tendencies have always shown that they are more susceptible to false information, even if it is non-political. However, in different cultural backgrounds, the connection between ideology and being misled is not always consistent. Other factors, such as higher numerical operation ability, cognitive and analytical thinking mode [36,40,41], are negatively related to the susceptibility to false information, although other scholars have identified partisanship as a potential regulatory factor [42,43,44]. In fact, these individual differences lead to two competing overall theoretical explanations of why people are easily misled. The first theory is usually called the classic "negligence" (inattention) theory; The second theory is usually called "identity protection" or "motivational cognition" theory. I will discuss the new evidence of these two theories in turn.

1.1 negligence explanation

Inattention account or classical reasoning theory holds that people are committed to sharing accurate content, but the social media environment will distract people’s attention and make them unable to make a decision to share news according to their preference for accuracy. For example, considering that people are often bombarded by online news content, most of which are emotional and political, and people have limited time and resources to think about the authenticity of a news, it may seriously interfere with their ability to accurately analyze these contents. The explanation of inattention draws lessons from the dual-process theory of human cognition, that is, people rely on two essentially different reasoning processes. They are system 1, which is mainly automatic, associative and intuitive, and system 2, which is more reflective, analytical and thoughtful. A typical example is the Cognitive Reflection Test (CRT), which gives a series of difficult problems. When faced with these difficult problems, people’s intuition or first answer is often wrong, and the correct answer requires people to stop and think more carefully. The basic point is that activating more analytical system type 2 reasoning can transcend the wrong system type 1 intuition. The evidence of negligent explanation comes from the fact that those who scored higher on CRT tests [36,41], those with stronger thinking ability [48] and those with stronger mathematical ability [4],People with higher knowledge and education [37,49] can better distinguish between true and false news [36] regardless of whether the news content is consistent politically. In addition, experimental intervention measures enable people to better think analytically or consider the accuracy of news content [50,51]. It has been proved that these measures can improve people’s decision-making quality of sharing news and reduce people’s acceptance of conspiracy theories [52].

1.2 Motivation reasoning explanation

In sharp contrast to negligence, the theory of (political) motivation reasoning [53,54,55] holds that lack of information or reflective reasoning is not the main driving force for susceptibility to false information. Motivational reasoning occurs when a person starts the reasoning process with a predetermined goal (for example, someone may want to believe that the vaccine is unsafe because their family members share this belief), so the individual will interpret new (false) information to achieve that goal. Therefore, the motivated reasoning account holds that people’s loyalty to groups that have affinity with them is the reason why they selectively approve media content that can strengthen deep-rooted political, religious or social identity. There are several variants of politically motivated reasoning, but the basic premise is that people pay attention not only to the accuracy of news content, but also to the goals that this information may serve. For example, when a fake news happens to provide positive information about someone’s political group or negative information about a political opponent, the news will be regarded as more credible. A more extreme and scientifically controversial version of this model, also known as "motivated numeracy" [59], shows more reflection and analysis, that is, the reasoning ability of System 2 can’t help people make more accurate assessments, but in fact it is often hijacked to serve identity-based reasoning.The evidence of this statement comes from the fact that on controversial scientific issues, such as climate change [60] or stem cell research [61], people with the highest computing ability and education level have the greatest differences. Experiments also show that when people are asked to make causal inferences about a data problem (such as the benefits of a new rash treatment), people with strong computing skills perform better on non-political issues. In contrast, when the same data is presented as a new research result of gun control, people become more extreme and inaccurate. These patterns are more obvious in people with higher computing power. Other studies have found that politically conservative individuals are more likely to (wrongly) judge false information from conservative media than from free media, and vice versa for political liberals-which highlights the key role of politics in distinguishing the truth from the false information [62].

1.3 Susceptibility: Limitations and Future Research

It is worth mentioning that both of these statements are facing great criticism and restrictions. For example, the independent replication experiment of intervention measures aimed at improving accuracy revealed different results [63], and questioned the conceptualization of partisan bias in these studies [43], including the possibility that the intervention effect was influenced by people’s political identity [44]. On the other hand, there are several failed and inconsistent repeated experiments in motivation reasoning theory [64,65,66]. For example, a national representative large-scale study in the United States shows that although the polarization of global warming among party members with the highest education level at the baseline level is indeed the most serious, by emphasizing the scientific consensus on global warming [66], experimental intervention measures offset or even reverse this influence. These findings lead to a greater confusion. In the literature of motivational reasoning, partisanship may only be due to selective contact, not motivational reasoning [66,67,68]. This is because the role of politics is confused with people’s previous beliefs. Although people are polarized on many issues, it does not mean that they are unwilling to update their (misguided) beliefs based on evidence. In addition, people may refuse to update their beliefs, not because they refuse the motivation reasoning of information, but simply because they think that the information is not credible, or because they ignore the authenticity of the information source or the content itself. This "equivalence paradox"[69] makes it difficult for us to separate the accuracy from the preference based on motivation.

Therefore, future research should not only carefully manipulate people’s motivation to deal with politically inconsistent (false) information, but also provide a more comprehensive theoretical explanation of the susceptibility to false information. For example, for political fake news, identity motivation may be more prominent; However, mechanisms such as lack of knowledge, negligence or confusion are more likely to play a role in dealing with false information about depoliticized issues (such as lies about treating the common cold). Of course, public health issues such as Covid-19 may be politicized relatively quickly. In this case, the importance of motivational reasoning in aggravating the susceptibility to false information may increase. Accuracy preference and motivation reasoning often conflict. For example, people may understand that a news story is unlikely to be true, but if false information promotes the goals of their social groups, they may be more inclined to give up their desire for accuracy and pursue motives that conform to their community norms. In other words, in any particular context, the importance people attach to accuracy and social goals will determine how and when they update their beliefs based on false information. When explaining why people are easily influenced by false information, paying attention to the interaction between accuracy and social and political goals can gain many benefits.

Second, communication

2.1 Measuring the information epidemic

Back to the analogy with viruses, researchers adopted epidemiological models, such as susceptibility-infection-rehabilitation (SIR) model, to measure and quantify the spread of false information in online social networks. In this case, R0 often represents those who start publishing fake news after contacting people who have been infected. When R0 is greater than 1, false information will increase exponentially and spread to form an information epidemic. When R0 is less than 1, the information epidemic will eventually die out. The analysis of social media platforms shows that all these platforms are likely to promote the spread of similar information epidemics, but some platforms are more likely than others. For example, research on Twitter found that fake news is 70% more likely to be shared than real news, and it takes six times as long for real news to spread to 1,500 people. Although fake news spreads faster and deeper than real news, it must be emphasized that these findings are based on a relatively narrow definition of news after fact checking. Recent studies have pointed out that these estimates are likely to be related to the platform.

More importantly, some studies have shown that fake news usually represents only a small part of all media consumption, and the spread of false information on social media is highly distorted. A small number of accounts are responsible for sharing and consuming most of the content, and these accounts are also called "super sharers" and "super consumers" [3,24,73]. Although most of these studies came from the political field, they also found very similar results in the context of COVID-19’s popularity. During this period, the super communicators on Twitter and Facebook had a great influence on the platform. One of the main problems is the existence of echo chamber, in which the flow of information is often systematically biased towards like-minded people. Although the infection of echo chamber is controversial, the research shows that the existence of this polarized group encourages the spread of false information and hinders the spread of error correction information.

2.2 Contact does not mean infection.

Contact estimation based on social media data is often inconsistent with people’s self-reported experiences. According to different opinion polls, more than one third of people report frequent contact with false information (if not daily contact). Of course, the effectiveness of people’s self-reported experiences may be different, but it raises the question of the accuracy of contact estimation, which is often based on limited public data and may be sensitive to model assumptions. In addition, a key factor to consider here is that contact does not mean persuasion (or "infection"). For example, the study of news headlines in COVID-19 shows that people’s judgment on the authenticity of headlines has little influence on their sharing intention. Therefore, people may choose to share false information for reasons other than accuracy. For example, a recent study found that people often share content that looks "if it is really interesting". This study shows that although people think fake news is not accurate enough, they think fake news is more interesting than real news, so they are willing to share it.

2.3 Communication: Limitations and Future Research

The research on "communication" faces great limitations, including the key gap in knowledge. People are skeptical about the ratio from contact with false information to beginning to truly believe false information, because the research on media and persuasion effect shows that it is difficult to convince people with traditional advertisements. However, the existing research often uses artificial laboratory designs, which may not fully represent the decision-making environment for people to make news sharing. For example, studies often test whether false information from different societies and traditional media spreads after one-time contact with a single information. Therefore, we need to better understand the frequency and intensity of contact with false information that eventually leads to persuasion. Most studies also rely on publicly available data shared or clicked by people, but people may be exposed to more information and more influenced by information when scrolling social media streams. In addition, fake news is usually conceptualized as a URL list that is verified to be true or false by facts, but this type of fake news only represents a small part of false information; People may be more likely to encounter misleading or manipulative content than obvious false content. Finally, micro-targeting efforts will greatly improve the ability of false information makers to identify and lock in the most easily persuaded individual subgroups [83]. In short, more research is needed to draw an accurate and effective conclusion on the possibility of infection (that is, persuasion) caused by horizontal exposure to false information.

Third, immunity

A rapidly emerging research direction is to evaluate the possibility of protecting the public from false information at the cognitive level. I will classify these studies according to whether their application is mainly prevention (pre-exposure) or treatment (post-exposure).

3.1 Treatment: fact checking and revealing the truth.

Traditional and standard methods to deal with false information usually include correcting lies after people have been persuaded by a piece of false information. For example, revealing false information about autism intervention measures has been proved to be effective in reducing support for treatments without evidence support (such as dieting) [84]. Access to the court-mandated corrective advertisements on the link between smoking and diseases in the tobacco industry [85] can increase knowledge and reduce misunderstandings about smoking. In a randomized controlled trial, a video effectively debunks several misunderstandings about vaccination and reduces some influential misunderstandings, such as the misconceptions that vaccines can cause autism or reduce the strength of the natural immune system. Meta-analysis unanimously found that the intervention measures of fact checking and revealing the truth are effective, including cracking down on false information that is harmful to health on social media.

However, not all medical misunderstandings can be corrected equally. In fact, these analyses also point out that the effectiveness of intervention will decline significantly with the following factors: (1) the quality of refutation, (2) the passage of time, and (3) previous beliefs and ideologies. For example, the above-mentioned studies on autism and smoking correction advertisements were ineffective after 1 week and 6 weeks of follow-up, respectively. When designing corrections, it is usually not enough to simply mark information as false or incorrect, because correcting false information through simple withdrawal can’t make people understand why information is false and what the facts are. Therefore, the advice to practitioners is often to write more detailed materials to expose the truth. A review of the literature shows that [91,92], the best practices of designing and debunking false information include:

1. Tell the truth first;

2. Appeal to scientific consensus and authoritative expert resources;

3. Ensure that the correction is easy to obtain and is no more complicated than the original false information;

4. Clearly explain why false information is false;

5. Provide a coherent alternative causal explanation (Figure 1).

Although there is a general lack of comparative research, some recent studies show that optimizing the way to expose information according to these criteria will improve the effect compared with other or business-as-usual methods [84].

　

Figure 1. Best practice suggestions for effectively exposing false information. An effective information to expose the truth should start with facts and be presented in a simple and unforgettable way. Then you should warn the audience about false information (don’t repeat this false information). Then identify and expose the manipulation techniques used to mislead people. Finally, repeat the facts and emphasize the correct explanation.

3.2 Revealing the Truth: Limitations and Future Research

Despite these advances, people still express great concern about the application of this kind of "therapeutic" correction afterwards, especially the risk of "backfire effect", and people eventually believe more false information because of the correction. This counterproductive effect can occur through two potential dimensions [92,93], one of which involves the psychological response to correction itself (backfire effect of "world outlook"), and the other involves the repetition of false information (backfire effect caused by "familiarity"). Although early research supports the fact that, for example, correcting false information about influenza and MMR vaccine may make individuals who have been concerned about these things more hesitant about the decision to vaccinate, recent research has found no evidence to prove the backfire effect of this world view. In fact, although the evidence of backfire effect is still widely cited, recent repeated experiments failed to reproduce this effect when correcting false information about vaccines. Therefore, although this effect may exist, its frequency and intensity are not as common as previously thought.

We can also design a way that is consistent with the audience’s worldview rather than conflicting to expose false information, so as to minimize the backfire effect at the worldview level. Nevertheless, because exposing lies means imposing a rhetorical framework on the audience, in this framework, in order to correct false information, it is necessary to repeat these false information (that is, refute other people’s statements), so there is a risk that this repetition will enhance people’s familiarity with false information, and people will not be able to correct it in long-term memory later. Although studies clearly show that people are more likely to believe repeated (false) information than non-repeated (false) information, recent studies have found that the risk of ironically strengthening a false information is relatively small when exposing a lie, especially when the information that exposes the lie is highlighted relative to the false information. Therefore, the current consensus is that although practitioners should be aware of the risk of backfire, considering that these side effects are rare, they should not prevent the release of correction information.

Having said that, there are two other noteworthy problems that limit the effectiveness of the treatment. First of all, retrospective correction will not be known to as many people as the initial false information. For example, it is estimated that only about 40% of smokers have received the correction information ordered by the tobacco industry court [98]. Another related concern is that people will continue to make inferences based on lies even after receiving the corrected information [92]. This phenomenon is called "persistent influence of false information", and meta-analysis has found strong evidence of persistent influence effect in a wide range of situations [88,89].

3.3 Preventive Measures: Psychological Prevention Theory of False Information

Therefore, researchers have recently begun to explore preventive or preemptive measures to deal with false information, that is, to act before individuals come into contact with or reach the "infectious" state. Although "precaution" is a more general term, it is used to refer to the intervention measures that remind people to "think twice before publishing events" [51], but this self-reminding does not enable people to have any new skills to identify and resist false information. The most common framework to prevent harmful persuasion is psychological prevention theory (Figure 2)[100,101].

The theory of psychological prevention follows the medical analogy and assumes that just as vaccines trigger antibody production to help acquire immunity against future infections, this can also be achieved at the information level. By pre-emptive warning and exposing people to seriously weakened false information (plus strong refutation), people can cultivate cognitive resistance to future false information. Psychological prevention theory plays a role through two mechanisms, namely, (1) motive threat (a desire to protect oneself from manipulation attack) and (2) refuting pre-emptive strike (an example of attack weakened by prior contact). For example, the study found that vaccinating people before (rather than after) exposure to conspiracy theories to prevent conspiracy arguments about vaccines effectively increased the willingness to vaccinate. Recent reviews [102,104] and meta-analysis [105] point out that psychological prevention is a powerful strategy, which can gain immunity to false information, and has many applications in the health field, such as helping people form immunity to false information of mammography in breast cancer screening.

　

Figure 2. Psychological prevention includes two core components: (1) warning people in advance that they may be misled (activating the psychological "immune system"); (2) Exposing false information (strategy) in advance, exposing people to seriously weakened false information, coupled with strong counterattack and refutation (producing cognitive "antibodies"). Once people gain immunity, they can indirectly spread the "vaccine" to others through offline and online interaction.

In particular, some recent progress is worth noting. First of all, the field of psychological prevention has shifted from narrow-spectrum or fact-based prevention to broad-spectrum or technology-based immunity [102,108]. The reason behind this change is that although we can synthesize a seriously weakened false information from the existing false information (and then strongly refute this weakened information), it is difficult to expand the scale of psychological prevention if this process must be repeated for every false information. On the contrary, scholars have begun to identify the common components of false information more generally, including impersonating experts and doctors, manipulating people’s emotions with fear, and using conspiracy theories and other techniques. It is found that people can resist these potential routines through psychological prevention, so people’s immunity will be relatively enhanced for a series of false information using these strategies. This process is sometimes called cross-protection. Inoculating people with a strain can prevent related or different strains from adopting the same false information strategy.

The second progress is about the application of active prevention and passive prevention. The traditional prevention process is passive, because people will get specific rebuttal information from experimenters in advance, while the active prevention process encourages people to produce their own "antibodies". Perhaps the most famous example of active prevention is the popular gamification prevention intervention, such as in the games Bad News and GoViral! In [110], the player plays the role of a false information producer, and is influenced by common strategies used to spread false information in a simulated social media environment. As part of this process, players actively generate their own media content and reveal manipulation techniques. It is found that when people (1) realize that they are easily persuaded and (2) perceive improper intentions to manipulate their opinions, they will resist deception. Therefore, these games aim to reveal the vulnerability of people’s cognition and stimulate the spontaneity of individuals by contacting with weak doses of false information in advance, so as to protect themselves from the influence of false information. Randomized controlled trials have found that active prevention games can help people identify false information [38,110,113,114], enhance people’s confidence and insight into the truth [110,113], and reduce the sharing of false information reported by themselves. However, like many biological vaccines, studies have found that psychological immunity will weaken over time, but it can be maintained for several months through regular "booster shots". One of the benefits of this research is that as a member of the World Health Organization,As part of the "Stop The Spread" campaign and the "Verified" initiative of the United Nations and the British government, these gamification interventions have been evaluated and promoted by millions of people.

3.4 Preventive Measures: Limitations and Future Research

One potential limitation is that although false information has appeared repeatedly throughout history (considering the similarity between the false information that vaccinia vaccine will turn people into cattle hybrids and the conspiracy theory that COVID-19 vaccine will change human DNA), psychological prevention really needs at least some advance knowledge about the false information that people may come into contact with in the future. In addition, because medical workers are being trained to fight against false information, it is important to avoid terminology confusion when fighting against vaccine suspicion through psychological prevention. For example, this method can be implemented without a clear analogy with vaccination, focusing on the value of "prevention" and helping people expose manipulation techniques.

Several other important open problems still exist. For example, similar to the recent progress in the application of therapeutic vaccines in experimental medicine: therapeutic vaccines can still enhance the immune response after infection-studies have found that psychological prevention can still protect people from false information even if they have been exposed to false information [108,112,118]. This is conceptually meaningful, because it shows that it may take a long time to repeatedly contact with false information before it can be completely convinced by false information or integrated with previous attitudes. However, there is still no clear conceptual boundary between the transition from therapeutic vaccination to traditional debunking the truth.

In addition, although active prevention and passive prevention are relatively close [105,110], the evidence base of active prevention is still relatively small. Similarly, although studies comparing prevention with debunking the truth show that prevention is indeed better than post-treatment treatment, more comparative studies are needed. The study also found that it is possible for people to post information about psychological prevention on interpersonal or social media. This process is called "post-inoculation talk" [104], which implies the possibility of group immunity in online communities [110], but there is no social network simulation to evaluate the potential of psychological prevention. The current research is also based on self-reported false information sharing. Future research needs to evaluate the extent to which psychological prevention can spread among people and affect the objective news sharing behavior on social media.

summary

The spread of false information undermines the efforts of public health work, from vaccination to public compliance with health protection behaviors. It is found that although people are sometimes deceived by misleading information because of their negligence and insufficient attention to the accuracy of information on social media, the politicized nature of many public health problems shows that people will also strengthen important social and political beliefs and identity structures by doing so, thus believing and sharing false information. We need a more comprehensive framework, which is sensitive to different backgrounds and can explain different susceptibility to false information according to how people give priority to accuracy and social motivation when judging the authenticity of news media. Although "exposure" does not mean "infection", false information can spread rapidly on the Internet, and its spread often benefits from the existence of political echo room. However, it is important that a lot of false information on social media often comes from influential accounts and super communicators. Both therapeutic methods and preventive methods have proved that some success has been achieved in fighting against false information. However, in view of the persistent influence after exposure to false information, preventive methods are of great value, and more research is needed to determine how to best combine exposure and prevention. We should also encourage further research to outline the psychological principles and potential challenges behind the application of epidemiological models to understand the spread of false information. A major challenge in this field in the future will be to clearly define how to measure and conceptualize false information, and to need standardized psychometric tools to better compare the results of various studies.

Original title: Overview of Information Epidemiology: Susceptibility, Dissemination and Immunity of False Information

Read the original text

Special feature of 1905 film network 6.758 billion!According to the statistics released by the National Film Bureau, the Spring Festival in 2023 lived up to expectations, successfully surpassing the box office record in 2022 with a box office score of 6.758 billion, and at the same time achieving the second good result in film history.High-quality works with diverse types and styles have also successfully attracted more than 129 million people to enter the cinema again during this Spring Festival holiday.

The total box office brought surprises, and the single-chip performance was equally wonderful.

From the opening of the painting on the first day of New Year’s Day to the end of the sixth day holiday, the two "head" blockbusters successfully crossed the 2 billion mark, and the title winner "Man Jianghong" finally won with over 2.606 billion yuan, and "Wandering Earth 2" gained 2.163 billion yuan. The third place "Bears Come and Go with Me" is the most "unexpected". It entered the third place with 747 million yuan for the ninth time in the Spring Festival file, and ranked fourth to sixth.

In addition, under the condition of the key continuation, the film played a super stamina and won 49.67 million box office, ranking seventh in the Spring Festival file.

The film, which was originally released on the third day of the New Year’s Eve, announced on the evening of the fourth day that it would change its distribution strategy, focusing on point screening, and the schedule was changed to February 17.

The head is super stable: "Man Jiang Hong" and "Wandering Earth 2" both broke 2 billion

The 6.758 billion box office data not only represents the second new record in the history of Spring Festival screening, but also witnessed a real "hundred flowers blossom" in China movies.

Compared with previous years, the 2023 Spring Festival movies are not only significantly genre-oriented, but also more "stable" in market performance. The "Head" blockbusters "Man Jiang Hong" and "Wandering Earth 2" both achieved box office of 2 billion+during the holidays. Excellent quality helped the two works to lead the data fault, but also brought more vitality and topicality to the film market.

Four years ago, the first The Wandering Earth hit the top by opening the first year of China science fiction movies, and the accumulated passers-by helped the sequel easily win the first place in the pre-sale stage. On the first day of its release on New Year’s Day, Wandering Earth 2 also made a strong start, reaching the top of the daily list with 479 million yuan.

Previously, the director, as the representative, had been treading on thin ice whether the audience was still willing to "remain tolerant", and then, with high reputation and high score, Wandering Earth 2 set off discussions on the whole network from the brain-burning plot in the play to the "high-tech equipment" outside the play. Whether it’s the space elevator, digital life, or "China Aerospace Squadron’s over 50-year-old exit", the audience has reason to believe that "Little Broken Ball" really "knocked open" the door of China’s sci-fi film creation in four years.

It consistently ranked second in the box office list, which enabled Wandering Earth 2 to reach nearly 2.2 billion box office on the last day of the holiday. This achievement also surpassed the first The Wandering Earth, helping the film win the sci-fi category champion in the Chinese New Year film history.

"Man Jiang Hong", which was originally followed closely, staged a wonderful and rapid "reversal" without losing the plot on the second day of the New Year’s Day.

The powerful appeal of the "luxury creative lineup" made the film achieve the double overtaking of "Wandering Earth 2" in the next day. And the elements of Tiger Balm comedy, which drove it to successfully realize the "sinking" of the market, made Manjianghong sit firmly at the top of the list for the rest of the holiday. For the audience of the film "Above", there was once a craze for reciting the poem "Man Jiang Hong" and "punching in" Yuewang Temple.

For six consecutive days, the box office exceeded 400 million, and the third and fourth days were significantly "down" for two consecutive days, consolidating and expanding the leading edge of Manjianghong. In the end, the film won more than 2.6 billion box office in the schedule, easily won the 2023 Spring Festival title, and finally predicted that the box office had soared to more than 4.5 billion, which also created the director’s personal best so far.

Multi-film reversal: the best Spring Festival file for genre films to achieve word of mouth

"Stable" is not only the head blockbuster, but also an important factor for the 2023 Spring Festival to achieve a breakthrough in box office performance again.After years of deep cultivation, the series "Bears" has already become the most stable domestic animation IP for the basic disk of the Spring Festival file.

Since the first time in 2017, the box office has exceeded 100 million yuan, and the market share of Xiong Da and Xiong Er has continued to grow during the Spring Festival: after the last year, Cheng Lili ranked fourth in the schedule with 500 million yuan+,this year’s "Bear with You" began to exert its strength from the second day of its release, only behind "Double Heroes", "Man Jiang Hong" and "Wandering Earth 2", firmly occupying the third place in the box office list.

Among them, from the beginning of the fourth day, the film arrangement of "Bears with Me" Bear Core "successfully" reversed "for three consecutive days, which also won more box office for the film.

In 2022, it finally ended with 977 million yuan, creating the highest box office of the series. In 2023, during the Spring Festival alone, "Bears with Me" Bear Core "has already won 747 million yuan, and it is only a matter of time before it leads the series to break through the 1 billion mark. So far, the IP series box office has broken the 5 billion mark.

In this 2023 Spring Festival file, which is phenomenal in data, genre and topicality, other films on the list also have impressive performances.

"Reverse decline" has become the most frequent keyword in the second half of the Spring Festival.It’s not just "Man Jiang Hong" and "Bears Come and Go" by the head echelon. The film Nameless, which was rated as "having a certain threshold for watching movies" and has a relatively bipolar reputation, achieved a "reverse decline" on the fifth day of the Lunar New Year after being relatively weak in the opening competition.

"Deep Sea" with a large number of "tap water" also achieved a "reverse decline" beyond its box office performance in the second half of the fourth and fifth days.

In the end, the two films ranked fourth and fifth with 493 million and 359 million respectively.

What’s even more surprising is that the diversified types have also made a Spring Festival file with the best reputation in recent years. On the online ticketing platform, the scores of six movies in the Spring Festival file have almost remained above 9 points. Among them, the two "head" works have a good reputation, with the scores of 9.6 and 9.4, which confirms the progress of China’s film in story creation and industrialization, and makes the audience feel the greater possibility brought by the market "letting a hundred flowers blossom".

During the Spring Festival, all the film masters also called for civilized and rational competition in the form of collective initiative to promote the healthy development of the industry. And good works have successfully attracted more than 129 million people to return to the cinema during the Spring Festival to witness the new breakthrough of China movies.

The Spring Festival has made a good start, which gives us reason to look forward to a better 2023. We hope that more excellent films will be released in China in the new year, so that more filmmakers can meet the audience at the cinema!

"The charge and replacement fee of 300 yuan per month, 150 yuan’s accident insurance premium, and an electric car can take delivery."

Gao Hu, born in 1991, worked in a brand beverage factory in his hometown of Liaoning before coming to Beijing, and once earned 4,000 yuan a month.

"The income here is higher than that in my hometown, and the threshold is lower. I have also seen people with disabilities such as deaf-mutes come to deliver takeout. Anyone can do it, that is, earning more and earning less." Takeaway rider Gao Hu said.

Not only in Gao Hu, according to the latest figures released by the National Bureau of Statistics, by the end of 2021, there were 200 million flexible employees in China, including about 13 million take-away riders, accounting for nearly 1% of the national population base.

Flexible forms of employment, such as take-away riders, have expanded employment capacity and played a role as a reservoir. At the same time, the topic of social security for related people has been constantly discussed, such as no "five insurances and one gold", lack of insurance protection, repeated non-growth labor, unclear path of subsequent career development, and no promotion channel … In the opinion of experts, the relationship between flexible employees and platform enterprises exists in various forms, such as labor dispatch, contracting and agency. Labor relations are complex, and platform enterprises bear different social security responsibilities, so the protection of the rights and interests of new employees has become the most difficult problem to solve.

In recent years, the relevant state departments have continuously attached importance to the protection of labor rights and interests of the relevant groups, clearly put forward the standardization of employment, and made clear the responsibility of safeguarding workers’ rights and interests; Improve the system and fill the shortcomings in the protection of workers’ rights and interests; Guiding opinions such as improving efficiency and optimizing workers’ rights and interests protection services. However, safeguarding the labor rights and interests of the flexible employment population is complicated, and it must keep pace with the times. It also needs the platform and relevant departments to jointly promote it.

Riders are the "hands and feet" and "reservoirs" of platform economy, which may lead to unfair competition.

In July, 2021, Gao Hu became a "takeaway rider". In Gao Hu’s view, he ran a special delivery tour with flexible working hours and higher salary than his hometown. "10:00-14:00, 17:00-21:00, you must be online, and you can control yourself in other time periods. You run more than 40 orders every day and earn more than 9,000 yuan a month, compared with 4,000 yuan a month in your hometown. Dry takeaway earns more than the factory. "

Flexible and free work is a big reason why many people engage in take-away riders. Liu Hua, born in 1981, is a native of Miyun, Beijing. Before that, Liu Hua worked as a seller in a home store, and she chose to take delivery six months ago, also because this industry is simple and free. "There are too many meetings and rules in the mall, and we have to choose the sideline team. Finally, we will come to the US group to take out the team list."

The higher income than their hometown has also attracted many people to Beijing to join the army of takeaway riders. Born in Liu Yi in 2001, I worked as a KTV night service in my hometown in Hebei before I was hungry. "The main reason is that the salary in my hometown is too low, only 4,000 yuan a month; So I came to Beijing to run a takeaway. After all, this job is flexible and free. "

This job has also given many people the opportunity of short-term transitional life. Xu Hang, born in 2003, is from Chongqing, and will graduate from higher vocational education this year. He is in the internship period. He feels that the cost of living in the internship position arranged by the school is too high, and he is not interested in his major. He heard that the take-away industry makes a lot of money, so he wants to experience the work of a take-away rider.

Compared with special delivery, crowdsourcing is more free Li Jian introduced that the advantage of crowdsourcing is that it can work more flexibly. "For example, if there are no elevators in nearby communities, I will not take orders for high-rise buildings directly, so I don’t have to climb the stairs at all at the end of the day." He also said that I am used to crowdsourcing riders, and I can’t stand the constraints. I can rest at any time when it is windy and rainy, and the rider may have to go to work, and the afternoon peak must be online.

The inclusiveness of the profession has allowed the scale of take-away riders to continue to expand. From the data such as Meituan’s financial report alone, the total number of riders who earn income through Meituan’s platform has increased from more than 2.2 million in 2017 to 5.27 million in 2021. The number of people who are newly employed, including take-away riders and courier brothers, is far more than that. According to the data of the National Bureau of Statistics, by the end of 2021, the number of flexible employees in China has reached 200 million.

Flexible employment can be seen everywhere. Li Zhiqi, deputy director of the Economic Committee of the Beijing Municipal Political Consultative Conference, vice chairman of the Beijing Federation of Industry and Commerce, and chairman of the revitalization international think tank, believes that "the flexible employment groups such as take-away riders are the direct practitioners of the platform economy and the most important front-line executives of the platform economy. They are the hands and feet of the platform economy. Without them, the platform as a brain will not work, and its importance is beyond doubt."

Li Yan, dean of the same city recruitment research institute, told the Beijing News Shell Finance reporter that flexible employment is a new flexible employment mode. No matter the flexibility of time and quantity of workers, the flexibility of employment form or management mode, the threshold of the concept of "employment" has been lowered, the employment category has been broadened, and more workers can be absorbed. Flexible employment provides more choices for further deepening mass employment and entrepreneurship.

The report "Talent Flow and Migration 2022" shows that more than half of the people in the workplace want to use their professional skills to "earn extra money". Wang Qian, co-founder of Pulse, said that as far as flexible employment is concerned, freelancing is not affiliated with any organization and has high flexibility in working time and place, which is conducive to ensuring work-life balance and carrying out various career development and life experiences.

The vice president of capital university of economics and business Institute of Labor Economics talked from more angles. From the perspective of employment, flexible forms of employment, such as take-away riders, have expanded employment capacity and played a role as a reservoir. From the perspective of the labor market, this part of employment has also produced unfair competition effect, because the platform operators and other operators bear lower tax burden and social security costs, which indirectly leads to inequality with formal employment enterprises; It has also led to the problems of difficult and expensive recruitment in the formal employment field.

The "Freedom Trap" of Linggong;Only pay work-related injury insurance, and salary disputes frequently occur.

Flexible employment only has the advantages of freedom of work? In fact, Liu Hua found that although the take-away industry is simple and free, it also faces the situation of not being respected. "After receiving the order from the platform, the customer will call me and buy some other goods by the way. If you don’t bring it, you will be complained. If you complain, you will be fined. There are also some communities that will open a special channel for takeaway riders and feel discriminated against. "

In addition to the low sense of professional identity, labor rights and interests are not perfect. "Five insurances and one gold should be a must. There are many people in the country who are like take-away riders. After a few years, what should these people do after they are 40-50 years old? If the family is seriously ill, they can’t even afford money. Moreover, the probability of traffic accidents is also high. " Liu Hua believes that the platform has really facilitated the people and solved many employment problems. However, most of the people who run takeout have low academic qualifications and poor family conditions.

During the interview, the Beijing News Shell Finance reporter learned that at present, take-away riders are mainly divided into special delivery and crowdsourcing. Basically, they do not sign contracts directly with the platform, and most of them are dispatched by third-party companies, and no matter whether they are special delivery or crowdsourcing, take-away riders do not have five insurances and one gold, and generally only pay work-related injury insurance.

In January last year, Han, a crowdsourcing rider, died suddenly on the way to delivery. Because he did not sign a labor contract directly with the platform, the platform was only willing to provide humanitarian compensation of 2,000 yuan to his family, which triggered a heated discussion in society. After the platform, the amount of sudden death protection was raised to 600,000 yuan. Although the incident has already come to an end, the fate and behind of the takeaway rider; The security of flexible employees has become one of the topics of great concern to the public.

Deng Jianbo, founder and CEO of Youth League, a flexible employment recruitment service platform, told the Beijing News Shell Finance reporter that due to the short working cycle, flexible workers generally do not sign labor contracts, which is more prone to salary disputes, and it is difficult to be supported after disputes. At the same time, in terms of insurance, the process of both individual purchase and enterprise purchase is complicated, resulting in a low purchase ratio. On the whole, the salary guarantee and life insurance guarantee of flexible employees are relatively general.

An industry insider who uses a flexible employment intermediary platform is also rethinking the intermediary model. "Platforms like Meituan and SF can increase employment, so that some people can receive jobs and earn income. However, similar employment intermediary platforms serve (Meituan, Shunfeng) platforms, and the way to solve (reduce) the labor cost of the upstream platform by self-employed mode and harm the rights and interests of workers (riders) remains to be discussed. The so-called failure to create any jobs refers to these fiscal and taxation solution platforms, not to Meituan and Shunfeng. "

However, Wang Feng wants social security, because social security has been paid in the work system before, and many riders "don’t need" but actually "don’t know". For example, Liu Yigang has only been in contact with this job for more than half a month, and he is not clear about the unit price and social security of the job. "I just did it soon, and I didn’t attend the regular meeting of the site at 9: 00 in the morning. The specific guarantee is not clear."

"Many riders will think that they have worked hard for such a long time, and as a result, they have deducted so much money into the social security account in one month. If they don’t work, they can’t find a place to ask for this money. They are definitely not happy in their hearts. It is better to get all the money directly and be practical in their hearts." The rider Fang Duanxin said that many riders need to see cash, and the platform can basically withdraw cash immediately.

Gao Hu also paid little attention to this part and paid more attention to real income. "Takeaway can’t last a lifetime. A long three to five years or a short year or two is a transition. For example, I earn 10,000 now, and I may have 8,000 left after paying five insurances and one gold, but I have paid five insurances and one gold for only a few years, which will not be consistent. "

Scope, vice president of capital university of economics and business Institute of Labor Economics, believes that "at present, most flexible employees are not included in the scope of labor law protection, so the relationship between them and the employment platform is adjusted according to civil legal norms. From a practical point of view, flexible employment groups such as take-away riders do not have much problems in terms of labor remuneration, but their working hours are generally too long; Take-away riders use vehicles for a long time, and security is a problem; In social insurance, industrial injury insurance is insufficient, and there will be problems in medical care and old-age care in the future. "

The protection of the rights and interests of newly employed people is the most difficult to solve, and individuals with unclear labor relations are under pressure.

As mentioned above, the discussion on labor relations of flexible employment has a long history. "The relationship between these practitioners and platform enterprises exists in many forms, such as labor dispatch, contracting and agency. Labor relations are complex, and platform enterprises bear different social security responsibilities, so the protection of the rights and interests of new employees has become the most difficult problem to solve. " Li Zhiqi mentioned.

According to the definition of flexible employment in China Renmin University’s China Flexible Employment Development Report (2022), in a broad sense, it is the employment arrangement of human resources allocation in ways other than standard employment, which is mainly divided into labor dispatch, business outsourcing, human resources outsourcing, Internet platform employment, traditional odd jobs (part-time employment, part-time employment, daily employment, self-employment cooperation) and internships.

The report also mentioned that in the traditional part-time jobs, part-time jobs, daily settlement, and more labour relation, dependent self-employment are mostly cooperative relationships, and only part-time employment is defined as labor relations. However, in this employment scenario, enterprises only need to pay work-related injury insurance for part-time workers, and do not need to pay economic compensation when terminating employment relations, so the employment flexibility is high.

The employment forms of Internet platforms are relatively complicated. Some platforms (and third-party organizations) are involved in production management, so workers have strong subordination to platforms (and third-party organizations), and there are substantial labor relations. However, most platform employees belong to the labor/business contracting relationship or "the situation that labor relations are not completely established but enterprises manage workers".　

Li Yan, president of 58 City Recruitment Research Institute, also said, "China’s flexible employment is still in its infancy. In the case of unclear labor relations and imperfect social security system, the pressures and risks that social individuals need to bear in flexible employment are various. For example, take-away workers may have to face labor disputes in three aspects: platform, merchants and customers at the same time. In addition, there are still shortcomings in employment safety and satisfaction, and even they cannot be completely independent in improving employment skills."

Fortunately, these relationships are being clarified at present. In July 2021, the Ministry of Human Resources and Social Security, the All-China Federation of Trade Unions and other eight departments issued the "Guiding Opinions on Safeguarding the Labor Security Rights and Interests of Workers in New Employment Forms", which mentioned that enterprises should conclude labor contracts with workers according to law if they meet the conditions of establishing labor relations. If the enterprise does not fully conform to the situation of establishing labor relations, but the enterprise manages the laborers (hereinafter referred to as the situation of not fully conforming to the situation of establishing labor relations), it shall guide the enterprise to conclude a written agreement with the laborers to reasonably determine the rights and obligations of the enterprise and the laborers. Individuals rely on the platform to independently carry out business activities and engage in freelance work, and adjust the rights and obligations of both parties in accordance with civil laws.　

In recent years, relevant departments have also continuously promoted the protection of labor security rights and interests of workers in new employment forms. During the two sessions of the National People’s Congress in 2022, the "Government Work Report" also proposed to strengthen flexible employment services, improve social security policies for flexible employment, and carry out pilot projects for occupational injury protection in new employment forms.

Relevant work has also been strengthened in various places, and many services have been launched in cities such as Beijing, where workers in new employment forms are concentrated. Relevant personnel of the Beijing Federation of Trade Unions told the Beijing News Shell Finance reporter that in September 2021, the Beijing Federation of Trade Unions issued the "Implementation Plan for the Beijing Federation of Trade Unions to Promote the Work of Trade Unions in New Formats and New Employment Groups" and introduced 10 measures to give full play to the role of trade unions as a bridge between the party and the workers, and earnestly safeguard the labor security rights and interests of new formats and new employment groups.

Recently, relevant personnel of the Beijing Federation of Trade Unions introduced that since June last year, the Municipal Federation of Trade Unions has promoted 17 Internet platform head enterprises such as JD.COM, Meituan and Didi, and 14 brand express delivery enterprises such as SF Express and "Three Links and One Reach" to establish trade union organizations, and accumulated 274,000 new employment form workers; More than 9,000 outdoor workers’ warm-hearted stations have been built; Provide five free guarantees such as major diseases and accidental injuries for workers and other groups with new employment forms.

Flexible employment needs to keep pace with the times, and the labor cost of regular employment should be properly balanced.　

As the Ministry of Human Resources and Social Security said, in recent years, the platform economy has developed rapidly, creating a large number of employment opportunities. The number of new employment forms such as online delivery agents, online car drivers, truck drivers, and internet marketers who rely on the Internet platform for employment has increased significantly, and safeguarding workers’ labor security rights and interests is facing new situations and new problems.　

Dealing with these matters must keep pace with the times. Li Zhiqi believes that flexible employment can’t be solved by the platform simply because of the different structure of labor relations. However, from the perspective of corporate social responsibility, the platform should guide partners to standardize the labor rights and interests of employed people. At the same time, the new format has new characteristics, and all parties need to work together to improve relevant systems and laws to protect the legitimate labor rights and interests of all types of employed people.

The scope indicates that from the perspective of improving the social security of relevant employment groups, it is necessary to solve the problem of occupational injury protection for flexible employment groups such as takeaway riders and courier brothers. Of course, there are preconditions for occupational injury protection, so it is necessary to strengthen the protection responsibility of the platform in terms of safety production, occupational safety and hygiene in operation and management, including providing corresponding occupational injury protection.

"From the perspective of governing the country according to law, it is necessary to properly balance the labor costs of flexible employment and formal employment, and the labor costs of the two forms of employment should not be too different because of institutional reasons. At present, there are some abnormal phenomena in the employment market, and some employed people give up formal employment and engage in flexible employment because of considering the immediate economic interests. In the future, in the field of social security, flexible employment should also share responsibilities appropriately. " Scope mentioned.

"The unit price of flash delivery is high, and the journey is long, which earns much more than takeaway." Gao Hu revealed that he has offered to leave his job and intends to run a flash. "I can save 6,000 yuan every month. After working in Beijing for a few more years, I can go back to second-and third-tier cities to pay the down payment to buy a house, marry and have children; I can still drive a van and live. This profession just has no sense of belonging in the short term. "

For many people, becoming a rider is just a transitional occupation, which also reflects the common problems in flexible employment, that is, the subsequent career development path is unknown and there is no promotion channel.

Li Yan said that to ensure the protection of workers’ rights and interests, the first step is to further optimize the three-tier adjustment model of labor law, reconstruct the functional division of labor law and civil law, and create a more benign and legal environment for the healthy development of flexible employment; Secondly, establish a vocational training system for flexible employment and open up more career paths for flexible employees; Finally, improve the occupational social insurance system for flexible employees and provide more employment security for flexible employment groups.

Under the guidance of local human and social departments, according to Liu Xinyang, vice president of Hungry, the platform is promoting the vocational skills upgrading training of the new format of "network delivery staff" nationwide. The course includes abnormal handling of distribution, cleaning and disinfection of lunch boxes, etc. There are both online teaching and practical teaching classes, and you can also receive special government subsidies after the training.

In the second half of 2021, Meituan announced the launch of "four major measures" to help riders’ career development, including Meituan’s rider vocational training and academic further education plan, stationmaster training plan, rider transfer plan, rider online learning platform and other career development measures. It will provide riders with a full-cycle, multi-level career development path, actively break the existing career development model of the rider group, and constantly broaden the radius of rider employment and career choice.

In addition, Deng Jianbo believes that scientific and technological forces should be promoted to protect the rights and interests of odd jobs. Through the HR SAAS system, B-end enterprises can use online modules such as shift attendance, salary calculation, electronic contract, employment insurance, talent pool operation, supplier management, etc., and C-end users can check in, pay their salaries, and get electronic contract and insurance protection.

Recently, the Beijing Federation of Trade Unions issued the "Key Points of Work of Beijing Federation of Trade Unions in Promoting New Employment Forms in 2022", which mentioned that it is necessary to build a strong organizational system and ensure that all the top 100 Internet companies operating in Beijing in 2021 will realize the establishment of the meeting; Adhere to the "one step forward" in safeguarding rights and earnestly safeguard the stability of the workforce in the new employment form. Including efforts to build harmonious labor relations, safeguard political security in the labor field, pay close attention to the demands of employees and other measures.

　　Huaxi Dushi Bao reporter Li Xiujiang

　　Photography Zhang Lei Someone asked our company to call your number for three months in a row. If you need to cancel it for a fee, please contact the staff and send a red envelope on WeChat … …

　　At noon on August 11th, Master Huang, who was running a taxi in Jiuzhaigou, suddenly received such a short message. He thought it was a scam message and didn’t care. As a result, after half an hour, the sound of the mobile phone never stopped.

　　In the meantime, Master Huang, who was unbearable to be harassed, turned the 100 yuan WeChat red envelope according to the other party’s prompt. Unexpectedly, the mobile phone was quiet for only half an hour and started ringing off the hook, and the other party asked for 200 yuan again. Worried that it was a bottomless pit, as a last resort, Master Huang turned to the operator where the mobile phone number was located and the police for help, and the answer was that there was no way to completely solve the problem.

　　On the one hand, there is endless noise, and on the other hand, there is nothing the supervision can do. In fact, Master Huang’s experience is not a case. Enter the keyword "Call you to death" on the Internet, and there are at least hundreds of similar news reports. The ultimate solution for these victims can only rely on themselves — — Block all strange calls or simply turn it off.

　　Behind this dilemma, there is a hidden status quo: software such as "call you to death" can be downloaded at will on the Internet, and even specialized companies use this kind of software to make profits by helping people "call you to death".

　　A

　　event

　　The brother who received the text message asking for a red envelope ignored it and was entangled in "calling you to death"

　　Master Huang has been running a taxi in Jiuzhaigou for several years, and this is the first time he has encountered such a thing: at noon on the 11th, he just received a guest who wanted to go from Jiuzhaigou to Chengdu. Not long after the car drove, he received a short message from a mobile phone number with a display area of Changsha, Hunan: "Someone asked our company to call your number for three consecutive months. If you need to cancel it for a fee, please contact the staff and send a red envelope on WeChat … …” At the end of the message, there are two WeChat numbers attached.

　　Master Huang thought it was a scam message and didn’t care. Unexpectedly, half an hour later, strange numbers began to call in. Some are strange numbers from other places, while others are unknown. They all hang up after ringing one or two times. Call back, the phone is either unanswered or the number is empty.

　　Master Huang was not too entangled in this because he was in a hurry to drive away. However, on the way from Jiuzhaigou to Chengdu, his mobile phone never stopped, ringing every 2 minutes, and the frequency was very uniform.

　　After 6 o’clock that night, the unbearable Master Huang could only "beg for mercy". He added the other party’s micro-signal according to the SMS prompt. "Who are you? Why do you want to do this? " For Master Huang’s inquiry, the other party did not answer, only said that he would help 100 yuan cancel the call if he wanted a red envelope.

　　After some bargaining, Master Huang first gave the other party a 50 yuan WeChat red envelope, but I didn’t expect the other party to have no room for negotiation at all. In desperation, Master Huang had to turn to 50 yuan again.

　　I thought this problem would be solved, but after half an hour of silence, Master Huang’s cell phone started ringing again. This time, the other person opened his mouth to 200 yuan, and said that no bargaining was allowed, otherwise he would "call you to death" for three consecutive months.

　　In the face of help and alarm

　　Both operators and police feel "headache"

　　Worried that it is a bottomless pit, Master Huang dare not remit money easily. Unbearable, he chose to ask for help from the operator who provided telecommunications services. The staff said that they would give feedback to the technical department, handle it in the background and give a reply within 24 hours. But after 24 hours, Master Huang failed to wait for the other party’s reply.

　　The harassing phone call still didn’t stop. Master Huang contacted the operator again, and the other party told him that there was nothing they could do to harass multiple strange phone numbers or display unknown numbers. The staff suggested that he download some interception software to stop it.

　　But this can’t solve the problem at all. Huang Shi Fu Shuo drives a taxi himself, and there are often strange calls for him, so it’s even more impossible to turn it off. Can continuously harass the phone, so that he can’t drive normally to attract customers.

　　As a last resort, Master Huang chose to call the police. The local police told him that he had received many such reports and had to register first.

　　As of press time, the number of harassing calls on Master Huang’s mobile phone has reached hundreds, and it has not stopped, and the time has exceeded 48 hours.

　　B

　　statement

　　The means to prevent "calling you to death" harassment are limited and it is difficult to intercept it comprehensively.

　　In fact, Master Huang’s experience is not a case. In the past two years, there have been seven or eight readers who have reported similar situations to this newspaper. Enter the keyword "call you to death" on the Internet, and at least hundreds of similar news reports will be searched out. The reporter combed the local media reports and found that in the case of "calling you to death", almost all the answers the victims got from the operators were: the problem could not be completely solved.

　　Mr. Cheng, a technical developer of an information technology company in Chengdu High-tech Zone, told reporters that "calling you to death" is actually an arbitrary dialing software that keeps repeating numbers. In the set time, keep dialing the number of the callee, so that the callee’s phone is busy, and other numbers cannot be dialed until the phone is turned off. Mr. Cheng said, "The incoming number of this kind of software is constantly changing. At present, mobile phones and fixed telephones should be guarded against ‘ Call you to death ’ The software means are extremely limited and cannot be completely intercepted. "

　　Mr. Cheng said that coupled with its concealment and variability, it is difficult for relevant departments to track down the perpetrators.

　　Earlier, some media reported that some experts in information engineering said that in case of "calling you to death" bombing, you can download mobile phone interception software. General interception software can mark harassing calls through big data, which can identify harassing calls faster than manual work and shorten the call time, but it can’t fundamentally prevent incoming calls.

　　C

　　survey

　　"Call you to death" software can be downloaded up to one million times online.

　　Why are more and more users being harassed by "calling you to death"? The reporter launched an investigation.

　　Enter the keyword "Call you to death" on the Internet, and there are many related messages. What is even more unexpected is that this software can be downloaded at will on the Internet, and some of them are accompanied by detailed installation and use instructions.

　　The reporter randomly clicked on the download page of a computer website and found a software called "Fast Phone Call You 2.8". At the bottom of the download link, there is a software introduction: calling your software to death requires the support of networked computers, and you can call numbers such as mobile phones or fixed telephones continuously until the power supply of the other number is exhausted, or it is always busy, so that other lines can’t call in unless the user turns it off by himself. The software also claims to be "the ultimate software for managing small advertisements".

　　After the reporter downloads, he can set the information such as call frequency and duration in the setting column, enter the mobile phone number or fixed phone number at will, and click the "Start Call" button, and the other party’s mobile phone or fixed phone will be continuously bombed. Incredibly, the downloads of this kind of software are amazing. By 5 pm on August 13th, this software had been downloaded more than 30,000 times on this website. According to CCTV’s previous report, the download volume of a software that "calls you to death" is as high as 1.25 million times, and the "praise" is as high as tens of thousands.

　　Corresponding to the download volume, it is a miserable victim. According to Anhui Business Daily, Mr. Xing, a citizen of Hefei, didn’t care when he received a strange text message. He actually received 4003 non-calling numbers in one day, and was called once every 21.6 seconds on average!

　　"Call you to death" is clearly marked online, and only 50 yuan can call for 3 days.

　　In fact, "calling you to death" has already become a complete interest chain. On the Internet, online stores and businesses that provide "call you to death" services can be easily found, and some businesses even openly price their services.

　　The reporter found a WeChat WeChat official account selling such services on the Internet, and the price offered by the other party was not high — — You only need 50 yuan to call any number for 3 days, and 100 yuan for 5 days.

　　After several days of investigation, the reporter found that in addition to free downloads, there are also some websites that sell such software publicly. Enter the words "Call you to death" on the Internet at will, turn over a few pages, and click to enter a computer website, which clearly indicates the price of the purchased product. A set of "call you to death" software, from purchase to activation and upgrade, is all guided online. The price of this kind of software varies according to the length of use. For example, the January version of 100 yuan, the half-year version of 280 yuan, and the lifetime version cost more than 2,200 yuan.

　　D

　　Support

　　Stopping the service of non-real-name telephone or VoIP may solve the problem.

　　Previously, the staff of telecom operators said that it was difficult to intercept "calling you to death", and some information technology experts said that downloading mobile phone interception software could not fundamentally prevent incoming calls. So, how to solve this problem?

　　Lawyer Huang Lei of Beijing Anbo (Chengdu) Law Firm has some research on this kind of cases. He said that in fact, operators can make a difference, and it is not difficult for him to solve this problem. "Telecom operators should strictly implement the real-name registration system, stop the service of non-real-name telephones or networks, so that they can’t call in or call out, which can effectively prevent others from using non-real-name registration system telephones or networks to commit criminal acts." Huang Lei said that once the real-name registration system is strictly implemented, it will be much easier to investigate and deal with it. At the same time, Huang Lei suggested that the telecommunications authorities should strengthen technical research and restrict these network violations from ports.

　　Lawyer’s statement/

　　"Call you to death" operator suspected of extortion

　　The "call you to death" operator’s behavior of asking Master Huang to "give money to eliminate the disaster" through SMS threats has been suspected of extortion. Lawyer Huang Lei said, from texting to voice asking for a red envelope, it is obvious that the operator’s behavior belongs to telephone harassment and forced asking for a red envelope. According to the Criminal Law and other relevant laws and regulations, for the purpose of illegal possession, the victim is forced to ask for public or private property by threatening or threatening. If the amount is large or repeatedly extorted, it is suspected to constitute extortion. The harassed person can report the crime of extortion and be investigated for criminal responsibility according to law.

　　Some lawyers believe that the act of "calling you to death" for private use infringes on others’ right to freedom of communication.

Recently, official website, the National Network Information Office, announced the third batch of problematic websites investigated and dealt with according to law in the 2020 "Clear Lang" special action and the special rectification activities of online class platforms. In addition to some live broadcast platforms, Baidu Post Bar is also impressively listed.

The reason why Baidu Post Bar was named this time: "LOLI Bar", "CQY Bar" and other post bars and accounts published pornographic information of underage "Welfare Ji", and sold pornographic selfies, videos and other resources of minors in the name of accompanying play and chatting.

In recent years, Baidu Post Bar has been paid attention to by the public every time, either because of rampant black production or because of malicious speculation, and there are few good things. At the end of September, a malicious phishing post "Brother, our family is rich" in Baidu Post Bar caused widespread discussion on the Internet because of the anxiety of selling bride price, which led a large number of angry netizens to rush into Baidu Post Bar, find the original post and accuse the landlord of being "selfish".

In the end, the incident took a surprising turn, and the posting party saw that the incident was getting worse and worse, so they had to admit that the post was fabricated and apologize to the public, but the poster also stressed that the post could not be deleted because of unknown reasons. The reason why this incident has become a hot topic is that someone has led the way and pointed out that the initiator is "Anti-stress Bar Team 1".

The reason why the incident successfully went out of the circle is unknown, but people can’t help but sigh that Baidu Post Bar, as one of the founders of the Internet community, has fallen to the point where it can only be remembered by maliciously fabricated public opinion events.

At that time, Baidu had money and resources. Even now, it is still a "skinny camel is bigger than a horse". However, Baidu Post Bar has gradually declined and lost its advantage in the community track.

The decline of Baidu Post Bar is not only attributed to the rise of competing products, but also to Baidu’s own strategic problems. Baidu’s attitude towards the light operation and light control of Post Bar makes the high-quality content of Post Bar languish day by day. Baidu Post Bar was born to improve the user’s stickiness, but Baidu seems to have forgotten for a long time that the loss of high-quality content pool will eventually lead to the shrinkage and collapse of the core business-search engine business.

From popularization to minority

Baidu Post Bar, launched in 2003, is a veteran Internet community. The idea of Post Bar came from Baidu CEO Robin Li. At that time, the search engine was considered as a "run-away" product, but Robin Li wanted to break this shackles, so he thought of making an interest community with keywords as the core, so Post Bar was born.

From the end of the 20th century to the first decade of the 21st century, online forums such as Maopu, Tianya and Post Bar jointly created a brilliant BBS era. However, the good times didn’t last long. After 2010, the barbaric growth of the mobile Internet created the rise of Weibo, and the old-fashioned communities that clung to the remnants suffered a huge impact, and Post Bar was no exception, and gradually declined.

The decline of communities such as Post Bar also lies in the high decentralization of these established communities. For example, each netizen’s post can be exposed relatively fairly according to the timeline. However, since its launch, Weibo has continuously highlighted the role of operation, taking the topic of stars and hot events as a gimmick to attract users to join. With the help of stars and hot topics, Weibo has become a new generation of Internet darling.

On the other hand, in the face of the rise of Weibo, Post Bar did not seek mutation, still stuck on its laurels, did not iterate frequently, and never made a big breakthrough in function and operation. A few years later, Zhihu rose. Zhihu, which is problem-oriented, is equivalent to a dimensionality reduction blow to Post Bar, because people will not only search for words but also search for questions on the search engine side, so that when people search for a certain question in Baidu, the more relevant search results are often the questions in Zhihu.

Although Baidu also has its own Q&A product, Baidu knows that it can complement the Post Bar in content, but it is still broken by Zhihu. Zhihu and Weibo are similar, with heavy operation and KOL as the core, so they successfully went out of the circle, further dividing the time and attention of netizens.

In early Zhihu, the invitation system was implemented, and there were many professionals and intellectual groups in various fields, and the atmosphere of seeking knowledge was strong, which laid the community tone of "knowledge first" in Zhihu. Therefore, a large number of outstanding creators were successfully precipitated, forming a differentiated competitive advantage with Baidu Know and Baidu Post Bar.

Post Bar and Baidu know that it is still a straggler, and there is no professional operation and integration of high-quality creator resources, which makes it difficult to form a high-quality content pool and thus it is difficult to retain high-quality users.

In June, 2016, something happened that dealt a further blow to Post Bar, that is, the launch of Weibo Chaohua. Before the introduction of Chaohua in Weibo, Post Bar has always been the main gathering place for fans. Fans can discuss stars in Post Bar, and even support activities can be organized through Post Bar.

Baidu Post Bar, which has a huge groupie user, has no star resources, but there are many stars in Weibo. After Weibo used his own star resources to launch Chaohua, Chaohua quickly became the core base for fans to discuss idols. As a result, a large number of fans have left the post bar.

What makes Baidu Post Bar even more embarrassing is that the bar service team, the core resource of Baidu Post Bar, is also moving closer to Weibo. For example, the most famous post bar "Li Yiba" (Diba) opened its official micro-blog in Weibo.

At present, Diba Guanwei has 1.17 million fans and has played a positive role in many sensitive events. Last August, Diba organized a massive "expedition" activity, which was highly praised by a number of official media. However, the traffic generated by the activities of Diba is not directed to the Post Bar, and it is still Weibo who enjoys the heat bonus.

At present, the hottest posts in Baidu Post Bar are mainly games, animation, digital and sports posts. Games and animation belong to the secondary subculture, while digital and sports are the favorite of straight men, and the diversity of users is relatively poor. Without the resources of stars and high-quality creators, groupies and high-quality users are constantly losing, and the audience of post bars is getting narrower and narrower, gradually sliding from the public to the minority.

Baidu’s mistake

The early post bar can become a phenomenal community product, and Baidu’s traffic blessing is very important. However, the decline of Post Bar is not only due to the rise of competitors, but also due to Baidu’s decision-making mistakes in products and strategies.

Li Yanhong’s continued contempt for the mobile Internet has led Baidu to miss the era of mobile Internet and lose its advantage in the mobile battlefield. When Baidu was aware of it, it had already given away its own traffic.

Baidu had many high-quality post bars in its early years, such as various post bars for postgraduate entrance examination and skill learning, which contained many dry goods and self-study tutorials. However, Baidu, which was weak on the mobile side, lost the favor of users, and people flocked to various learning classes in Weibo. There are also many young people who flock to bilibili to study. With the help of video, a more expressive medium, bilibili has a unique advantage in learning resources.

On the other hand, Baidu’s social strategy has always been to integrate social elements into core products, rather than developing a social product alone. Based on this idea, Baidu Post Bar failed to seize the opportunity of transformation and became a semi-community and semi-social product like Weibo.

In addition to the topic discussion, Baidu Post Bar has another identity, which is the "answer library" of Baidu search engine business. Because Baidu Post Bar is deeply bound to Baidu’s search engine, when users use Baidu to search for keywords, corresponding post bars will appear in the search results, and when users search for multiple keywords or sentences, posts with high relevance will appear in the search results.

Post Bar is born for interest, but for those who have no specific interest and just want to find the answer to the question in Post Bar, Post Bar is still a disposable product with poor user retention rate. However, the identity of "answer library" is not completely without benefits for Post Bar. For people who are not deeply exposed to the Internet, Post Bar located in the front row of Baidu search results is an important way for them to obtain information.

"Last spring, when I was Baidu’s mushroom farming skills, I found a post in the post bar to promote mushroom farming supplies, and the price was a little lower than the market price. Feng Yuqin is a mushroom farmer in the northeast rural area. She shared her experience of being cheated on Baidu Post Bar with "Internet insider". "Later, I added the post owner’s WeChat and bought more than 500 yuan of mushroom farming supplies through WeChat transfer. Later, the courier reminded me that the parcel was collected and the postage was more than 300 yuan. If you refuse, you won’t get your money back, because the seller has blacked out my WeChat, so you have to bite the bullet and pay the postage.

For Baidu Post Bar, there are not a few sinking market users like Feng Yuqin, who make it difficult to distinguish all kinds of information in the post bar. Over time, Baidu Post Bar has become a popular place for some unscrupulous traders.

There is no doubt that the UGC attribute of Post Bar is strong. If it is not re-operated and re-controlled, the community tonality will develop in an uncontrollable direction. Post Bar, however, is a product of Baidu’s "stocking". Post Bar is created by an individual application, and the bar staff has extremely high permission to post it. Baidu’s official operational role has been greatly weakened.

Baidu Post Bar’s official limited regulation of Post Bar has also been criticized as "three views are touching". In the emotional column of Baidu Post Bar, there is a classification of "beauty". Under this category, there are many post bars that cater to the preferences of diaosi groups, such as "black silk bar", "beautiful legs bar", "stunner bar", "connotation map bar" and "student girl bar", and these post bars are undoubtedly hotbeds for black production.

The recent exposure of "LOLI Bar", "CQY Bar" and other post bars selling underage "Welfare Ji" pornographic resources is the tip of the iceberg.

The prevalence of black products also shows that users of Post Bar have great value, but Baidu is "lazy" and has not explored a diversified profit model. For a long time, it has been realized by advertising, membership and selling Post Bar. At the beginning of 2016, the "hemophilia bar" was sold, which once caused Baidu to fall into a major public opinion crisis.

Due to the obvious community attribute, Post Bar is the most dynamic and advantageous product in Baidu’s own content pool, but now it has become Baidu’s "time bomb", and negative news will be exposed every one or two years, hurting Baidu’s vitality. It can be predicted that Baidu’s search business will become increasingly depressed if all kinds of ills of Post Bar are not removed.

Baidu urgently needs high-quality content pool.

As a search engine, Baidu’s nourishment includes its own content and external content, and building its own high-quality content pool is the key to enhance its competitiveness. Around the search engine, Baidu has developed a series of content products to expand Baidu’s content pool, including Baidu Post Bar, Baidu Know, Baidu Experience, Baidu Library, Baidu Encyclopedia and Baijiahao.

Baidu knows that the status quo of Baidu’s experience, like a post bar, has been largely replaced by Zhihu, a professional creator. After cracking down on piracy in China, Baidu’s library will no longer be brilliant. Baidu’s expectation of revitalizing high-quality content is pinned on Baijiahao, the benchmark WeChat WeChat official account.

However, the overall content quality of Baijiahao has been difficult to compete with WeChat WeChat official account. On the one hand, Baijiahao is different from WeChat WeChat official account’s "Hundred Flowers Bloom". Baijiahao is more inclined to recommend short information, and the long and in-depth content is not the main support object of Baijiahao, which hinders the development of high-quality content in Baijiahao to some extent; On the other hand, Baidu has a large user base and a high proportion of sinking users. Due to the influence of recommended algorithms, it is inevitable that low-quality content will prevail; Moreover, Baidu does not have a strong application ecology, which leads to the poor liquidity of Baijiahao, so few high-quality creators regard Baijiahao as the main position of content creation.

Baidu has not made efforts on specialized high-quality content, but this force target is Baidu Encyclopedia. Baidu Encyclopedia started the operation of high-quality content matrix around 2014, and derived content sections such as featured encyclopedia, second encyclopedia and V encyclopedia, and introduced authoritative creators in various fields to output high-quality content. However, the entrance of these high-quality content is deeply hidden and difficult to be found and used by users.

Encyclopedia of science under the classification of characteristic encyclopedias

Baidu’s planning mistakes in the high-quality content pool have caused the loss of users, the decline of word of mouth and the shrinking of core search business. StatCounter statistics show that in 2018, Baidu’s share in the domestic search engine market was 70.3%, and by 2019, this figure fell to 67.09%. The market share of sogou search and Shenma Search is rising steadily.

Sogou, backed by Tencent, launched the WeChat channel in 2014, which opened a huge pool of high-quality content, and launched the Zhihu channel in 2015, which means that sogou search has captured another city in the pool of high-quality content. Users who are increasingly eager for high-quality content are gradually migrating to sogou.

In addition to sogou, a strong rival, all mobile rivals are also eating into Baidu’s search business. The Shenma search created by UC and Ali has thrived under the protection of UC browser; Wechat and today’s headlines also started their own search business, feeding the growth of mobile search business with the application matrix of their own camp as nutrients.

Giants have built their own search businesses, and their confidence comes from their own layout in various content tracks. Wechat Search contains WeChat WeChat official account, video number, applet, Tencent video, WeChat reading, QQ music, JD.COM Mall and other channels, which is enough to support the basic disk of WeChat search; Headline search also integrates the resources of content products such as headline number, micro-headline, Tik Tok, headline question and answer, and has strong strength.

In contrast, Baidu’s content is short-lived. Baidu, which is centered on search engines, does not have a fist-level content product. When competitors are mainly based on their own content pools and supplemented by external content pools, Baidu products represented by Post Bar are gradually declining.

In the face of all kinds of big moves by competitors, such as holding a strong group or integrating the application matrix, if Baidu can’t make great progress in high-quality content, it will eventually lose the throne of the first search engine. If the search engine business loses its advantage, it will not be far from the total collapse of Baidu Empire.

　　Everything is for the safety of people’s lives and property ―― On-the-spot report on Fujian’s defense against typhoon "Seagull" 　

　　At about 14: 20 on July 18th, it was stormy in Xiapu section of Fujian Province, shenyang-haikou expressway. According to the latest news from Fujian Meteorological Observatory, the strong tropical storm "Seagull" landed in Changchun Town, Xiapu County, Fujian Province at 18: 10 on the 18th, with a central air pressure of 988 hectopascals, a maximum wind force of 10 near the center and a wind speed of 25 m/s.. Xinhua News Agency reporter Jiang Kehong photo

　　Xinhuanet Fuzhou, July 19 (Reporter Tu Hongchang, Lai Jianqiang, Kang Miao) At 18: 10 on the 18th, the "Seagull" which caused great disaster in Taiwan Province landed again in Mindong and entered Zhejiang in the early morning of the 19th. Although the intensity of the storm continued to weaken, it still triggered a large-scale rainfall in northern Fujian and southern Zhejiang.

　　Faced with the challenge of violent storms, Fujian quickly blew the "assembly number" to protect people’s lives and property. A series of tight and orderly anti-resistance measures have achieved good results. Up to now, the province has not found any casualties caused by typhoons.

　　"Seagull" is threatening.

　　This year’s No.7 typhoon "Seagull" was generated on the Philippine ocean at 14: 00 on the 15th, and then all the way to the northwest. At 21: 40 on the 17th, "Seagull", which gathered huge energy at sea, landed in the south of Yilan County, Taiwan. The sudden storm brought severe tests to Taiwan Province, which has always been well-trained in typhoon prevention and resistance.

　　According to statistics, from 17th to 18th, the main rainfall areas in Taiwan Province were concentrated in the area from the south of Miaoli to Pingtung, including Chiayi, Nantou, Tainan and Kaohsiung, with accumulated rainfall exceeding 1000mm. "Seagull" not only brings a lot of rainfall, but more seriously, the rainfall is very concentrated, which makes the flood worse and makes the drainage system in some cities unbearable.

　　According to the disaster report on Taiwan Province Island, the "Seagull" attack has caused 16 deaths, 11 missing, 673,000 families to stop water supply, many traffic trunk roads have been interrupted, some trains on the western trunk line of Taiwan Railway and high-speed rail have been stopped, flights at Taichung Qingquangang Airport have been suspended, Mazu’s foreign air and sea traffic has been interrupted, and Taiwan Province’s agriculture, forestry and animal husbandry have lost more than NT$ 110 million.

　　After passing through Taiwan Province, "Seagull" weakened from a typhoon to a strong tropical storm, and gradually approached the coastal areas of northern Fujian and southern Zhejiang. From 17: 00 on the 17th to the morning of 18th, Fujian Meteorological Observatory issued four typhoon yellow warning signals, saying that from 18th to 19th, some counties and cities in Fujian had heavy rain or rainstorm, and some counties and cities in Ningde and Fuzhou had heavy rain. "Seagull" affects Zhejiang Province during the flood season, which is prone to the phenomenon of wind, rain and tide, aggravating the harm. Therefore, the Zhejiang Flood Control and Drought Relief Headquarters started the typhoon-proof level II emergency response at 20: 00 on the 17th.

　　"’Seagull’ is generated offshore and moves fast. The radius of the 7-level wind circle reaches 300 kilometers. Landing at any point in Fujian will cover the whole of Fujian Province, and the resulting heavy rainfall will have a greater impact on Fujian, which requires the prevention and resistance work to be swift and rigorous." Wu Jinta, deputy director of the Fujian Provincial Flood Control Office, said.

　　From the 18th, Fuzhou swept away the sunny and hot weather a few days ago. The sky was cloudy with frequent showers, and large and small streams of water quickly appeared on both sides of some low-lying streets. Wang Chengdong, a citizen of Gulou District, went to the supermarket early in the morning to buy a refrigerator of vegetables and fruits. He said, "It is not convenient to go out when the typhoon comes. Stay at home on weekends and get ready for’ food and grass’."

　　After a long-distance attack of more than 1,000 kilometers at sea, at 18: 10 on the 18th, the "Seagull" with the maximum wind force of 10 near the center landed on the coast of Changchun Town, Xiapu County, Ningde City, Fujian Province again. The dark clouds hung low at the head of Xiapu County, and the roaring sea breeze blew the residents’ glass windows. Less than an hour after "Seagull" landed, the rain in Xiapu County gradually increased, and Xiapu’s transportation lines to other places, such as highways, national highways and maritime passenger routes, were blocked.

　　More than 300,000 people were transferred.

　　"The waves are so flat and there is no rain. Why can’t we go back to the fishing raft?"

　　"Now that the wind is back to the south, it may attack Sandu’ ao head-on, and it must be transferred immediately!"

　　At about 16: 00 on the 18th, Yang Shanbao, a fisherman in the Qingshan sea area of Sandu ‘ao, Jiaocheng District, Ningde City, refused to board the boat in the face of the mobilization of reserve officers and soldiers and town cadres. Seeing that the "seagull" was about to strike, Lan Tingjia, secretary of the Party Committee of Sandu Town, gave an order and took decisive measures to forcibly transfer it to a patrol boat and send it to a safe land for resettlement.

　　It turned out that at about 10: 00 on the 18th, "Seagull" turned northward to the coastal area of Zhejiang, and the sea area of Sandu was calm. More than 300 farmers thought that the typhoon would not reach Sandu, so they secretly ran back to the fishing raft. At about 13: 00, the typhoon returned to the south and attacked the coastal area of eastern Fujian. The cadres patrolling the sea found these secretly returning farmers, immediately mobilized them to go ashore, and forced them to transfer according to law. "The safety of people at sea is the most threatened by typhoons. Organizational transfer must be deployed in advance and implemented one by one, leaving no dead ends." Lan Tingjia said.

　　Wu Jinta said that according to the typhoon prevention plan of Fujian Province, people were transferred in steps during the typhoon, first the people on fishing boats and rafts, and then the people in low-lying, riverside, hillside and geological hazards. According to the statistics of Fujian Flood Control Office, as of 10: 00 on the 18th, more than 183,000 offshore workers had been safely transferred in Fujian province, including 29,300 offshore fishing rafts and 154,000 offshore vessels who entered the harbor to avoid the wind. According to the statistics of the National Flood Control and Drought Relief Headquarters, as of 10: 00 on the 18th, Wenzhou, Taizhou, Ningbo and Zhoushan in Zhejiang Province had transferred 170,000 people and returned to Hong Kong with 26,588 sheltered vessels.

　　Before the "Seagull" landed, more than 11,000 ships in Ningde City returned to Hong Kong in time to take shelter from the wind, and more than 15,000 fishermen were transferred to safety. A fisherman from Cangnan County, Zhejiang Province, told the reporter that it was because Ningde promptly informed all the vessels operating in the nearby waters to enter the harbor to take shelter from the wind before the typhoon landed that it escaped the strong tropical storm "Seagull".

　　Chen Rongkai, secretary of the Ningde Municipal Party Committee, said that after the typhoon landed, the gust of the sea near Xiapu County was still 9-10, and the secondary disasters caused by wind and rain still existed. Ningde City continued to maintain a high degree of vigilance and shifted the focus of its typhoon prevention work to the prevention of heavy rainfall. From the night of the 18th to the day of the 19th, it once again conducted a dragnet investigation on 1,390 hidden danger points of geological disasters in the city, focusing on preventing geological disasters such as mudslides and flash floods, and promptly transferring more than 140,000 people in various dangerous areas.

　　Huang Shuihua, an 80-year-old old man from Sandu ‘ao, Jiaocheng District, Ningde City, was transferred from a house in a low-lying area to a safe area in the urban area the day before the typhoon landed. The old man Huang Shuihua told reporters: "The people we transferred here have food, clothes, a place to live, clean water to drink, and timely treatment when they are sick, which is the blessing of the party and the government."

　　Good mechanism to ensure "near misses"

　　On the morning of 18th, Chen Jianping, director of Fuzhou Municipal Bureau of Organs Affairs, suddenly received a free mobile phone message: "According to the forecast of the Provincial Meteorological Observatory, Typhoon’ Seagull’ is expected to approach the coastal areas of northern Fujian and southern Zhejiang on the night of 18th, so please take precautions." Chen Jianping immediately launched the emergency plan of the unit, and arranged all the work to prevent and resist Typhoon No.7 "Seagull". Xiao Zhang, a citizen who temporarily went to work in Fuzhou Municipal Bureau of Organs Affairs, also received the same message and quickly informed his family.

　　Timely and transparent information disclosure is a major feature of typhoon prevention in Fujian Province. The Fujian Provincial Flood Control Office revealed that by more than half an hour before "Seagull" landed in Changchun Town, Xiapu County, Fujian had sent 5.15 million pieces of typhoon prevention public welfare information to mobile phone and PHS users in the province.

　　Fujian, with "eight mountains, one water and one field", is a province with frequent geological disasters, so the mountainous areas and rural grassroots are also greatly affected by typhoons and heavy rains. According to meteorologists, under the influence of seagulls, heavy rains and torrential rains have occurred in most counties and cities in Fujian Province, and the rainfall in 21 counties, cities and districts has exceeded 100 mm, so geological disasters are more likely to occur in some areas.

　　Qiu Tingmeng, spokesman of Fujian Flood Control and Drought Relief Headquarters, said that in order to strengthen the ability of grassroots villages to resist Taiwan and reduce disasters, Fujian Province has implemented the working mechanism of "early warning to the township, planning to the village, and responsibility to the people" this year. First, each township is equipped with a disaster prevention information receiving and republishing platform, and the early warning information is immediately transmitted to the relevant villages, units and flood control responsible persons through telephone, SMS and radio. Second, each administrative village should prepare relevant typhoon emergency plans; Third, the responsibility of each link in the typhoon prevention plan should be implemented to individuals.

　　In order to prevent the rainstorm and its secondary disasters, Zhang Changping, executive vice governor of Fujian Province, stressed that it is necessary to warn the county and township about the rainfall two hours before the rainstorm, and all localities should officially launch the disaster prevention and mitigation mechanism of "early warning to the township and pre-planning to the village", pay attention to the prevention of local rainstorms and extremely heavy rainstorms, focus on guarding and patrolling the hidden danger points of major geological disasters, and strengthen inspection and watch over dangerous reservoirs, high-water reservoirs and reservoirs upstream of densely populated areas to ensure safety.

　　Chen Rongkai, secretary of Ningde Municipal Party Committee, said that after the typhoon landed in Changchun Town, Xiapu County, Ningde City, millions of people in Ningde City were "near misses" and no one died from the disaster.

　　Although the typhoon has crossed the border, the work of preventing and resisting heavy rain in Fujian Province has not been relaxed. On the evening of 18th, Lu Zhangong, secretary of Fujian Provincial Party Committee, demanded that cadres at all levels should still go deep into the front line and command from the front, so that the plan can be effectively implemented. According to the rainfall situation, secondary disasters such as possible landslides should be closely monitored and the masses should be transferred in time. It is necessary to strengthen the responsibility mechanism, "we cannot cause losses to people’s lives and property because our work is not in place."
