"This gesture can save lives at a critical moment!" recently, a rumor about the so-called "international general alarm help gesture" spread on the Internet, saying that "first buckle your thumb, then fasten your four fingers and clench your fist, and everyone can immediately understand that you are sending out the alarm help signal of 'save me'.". On the short video platform, someone also specially photographed the scene story of people in distress asking for help through gestures and finally being rescued for "popular science", and called on netizens to forward "rescue" more people. Subsequently, the public security organ refuted the rumor against the rumor post. In fact, the rumor of "international alarm help gesture" is an old problem. As early as 2016, there were a variety of gesture rumor posts. Although the public security organ refuted the rumor, many people still sent it by mistake. Now, such rumors have changed a "gesture" to enter the public view again, widely spread on social media, and even spread in "police uniforms", which has increased the "credibility" of this rumor. It is noteworthy that these rumors will attract the attention of many people every time they appear, which not only shows that the people are eager to obtain authoritative legal knowledge, but also reflects the social reality that the popularization of law, which is highly close to people's daily life, needs to be improved. In case of danger, the time for the victim to call the police is likely to be fleeting. These rumors seem warm and considerate, but actually mislead the public. If they are not clarified in time, they may not only cause unpredictable and serious consequences to individuals, but also damage the trust between people and dispel the goodwill and love of the public. Therefore, in the face of specious and new rumors, it is very necessary to refute rumors and popularize the law in a timely and accurate manner. At the same time, how to take the initiative and occupy the highland of public opinion has also become a challenge for law enforcement and law popularization. Rumors in the name of goodwill reminders appear from time to time, or spread wrong information, or interpret relevant legal knowledge out of context, misleading the public, to some extent because of the absence of authoritative voice. The people's awareness of the rule of law is constantly improving, and their demand for authoritative information such as legal knowledge is increasing. Once they encounter relevant confusion, if they can't get authoritative information, they will often be misled by wrong information. Some people forward wrong information out of kindness, which virtually promotes the dissemination of wrong information. It is not difficult to find that one of the reasons is that there is still a certain gap between law enforcement and law popularization and the demands of the people. In the era of mobile Internet, information is within reach and spreads faster. The work of popularizing the law should keep pace with the times and work hard on pertinence and effectiveness. In recent years, all localities have actively innovated ways and methods, and the media communication forms with law popularization as the main content have become more and more diversified. Personalized law popularization products such as short video, webcast and animation have appeared frequently, which has promoted the transformation from one-way communication to interactive, service and scene communication, enhanced the people's sense of participation, and improved the accuracy and effectiveness of law popularization, The people have more diverse ways to obtain authoritative legal knowledge and information. The eighth five year plan for law popularization places special emphasis on forming a higher level of dynamic balance between the demand for the rule of law and the supply of law popularization. In this regard, only by starting from the people's daily life, starting from the lively and popular way of law popularization, and allowing the authoritative legal voice to reach more people, can we effectively avoid the harm of rumors and create a good atmosphere for the whole people to care, support and participate in the construction of a society ruled by law.
