　　 Moderator Jia Jie: Hello, friends from the press! Thank you for attending today’s press conference. Today, a press conference was held here, mainly to invite comrades from public security organs at two levels in the city to introduce that a criminal gang involved in triad activities was successfully destroyed, most gang members were arrested, and a number of cases were cracked, which effectively safeguarded the social order in Linhe area, and the broad masses of the people applauded.

　　 Liu Jingang, director of the Public Security Bureau of Linhe District, is invited to introduce the case investigation.

Liu Jingang, director of the Linhe District Public Security Bureau, introduced the investigation of the case

　　 Published by Liu Jingang:　According to the deployment of the Bayannaoer Public Security Bureau’s unified action of "cracking down on evils", with the great attention and support of the Linhe District Party Committee and the government, after more than three months of careful investigation by the public security organs at the city and district levels, the two were "bald" and "tattooed" as the main signs, and they were surrounded by Hu, lending money, illegally collecting debts, collecting protection fees, stealing and robbing money as their economic sources. Organized criminal gangs of black and evil forces who beat others at random, gathered in armed fights, raped women, illegally detained women and forced women to engage in prostitution were destroyed in one fell swoop. A total of 90 gang members were arrested and 169 criminal cases were cracked. A breakthrough was achieved in the special struggle against black and evil forces, which eliminated a "cancer" that affected the stability of social order in Linhe area, demonstrating the determination, confidence and ability of public security organs to crack down on black and evil.

　　 The Party Committee of Linhe District Public Security Bureau has always insisted on "cracking down on evil" as an important task for public security organs to safeguard people’s livelihood and maintain social stability. At the end of May, 2009, the Regional Bureau organized various police types to combine their daily work of handling cases, management and service, focusing on industries, places and regions that are easy to breed evil forces, and adopted methods such as thorough investigation and unannounced visits to understand and master deep-seated information. In the process of in-depth investigation and understanding of the public security situation in Linhe District, in early October, the Party Committee of the Bureau found that in the process of investigating many public security and criminal cases, there were a group of "bald-headed and tattooed" social youths, who were called "bald-headed gangs" by the masses, openly gathered in public casinos to fight, stir up trouble and collect protection fees, with a large number of people involved in the cases, and the circumstances of illegal crimes were bad. At that time, the public security organs all committed crimes as individual cases. The Regional Bureau attaches great importance to this situation. Through comprehensive analysis and judgment on many cases of affray, affray and intentional injury investigated and dealt with since 2008, the Party Committee of the Regional Bureau is keenly aware that these cases are likely to involve an organized criminal gang of black and evil forces, and immediately set up a task force with Director Liu Jingang as the team leader, Political Commissar Liu Ruiping, Deputy Director Zhang Yongping and Captain Tao Fazhi as the deputy team leader, and transferred elite police force from the Interpol Brigade to take charge of secret investigation and evidence collection. In view of the unusual complexity of the case and the vague internal structure of the organization, the task force went deep into the public entertainment places in Linhe District to secretly investigate and collect evidence, and went to several police stations in the city to collect the police records of each police station in recent years. The characteristics of the perpetrators are as followsIn all kinds of cases of baldness, the relevant cases have been carefully sorted out and investigated, and similar cases have been analyzed in series and parallel, and the basic situation and organizational structure of criminal suspects have been gradually grasped in the massive case information. The task force has also stepped up its efforts to detect and interrogate the existing cases in which the perpetrators are characterized as "bald heads", and investigated the composition of the gang and the characteristics of committing crimes.

　　 After more than two months of secret investigation, the task force obtained some criminal evidence and members of the "skinhead gang". The gang has a large number of people. Usually, it is divided into several small gangs. The economic source is to surround Hu, lend money, illegally collect debts, and collect protection fees. The members of the gang collectively board and board, and gang up in groups to beat others at random, illegally detain, and force women to engage in prostitution around the campus and public entertainment places. The criminal arrogance is very arrogant. The secret investigation of the task force also learned that in January 2008, two groups of "skinheads" gathered more than 50 people with machetes, bayonets and pickaxes in a remote part of the development zone because of a "site" dispute, causing many injuries, two of whom were seriously injured. Later, neither side reported the case and left the scene. The activities of the "skinhead gang" evil forces have extended to Wuhai, Wuqianqi, Wuyuan and other places, posing a great threat to social security and people’s sense of security.

　　After the task force reported the investigation to the project leading group, the regional bureau quickly reported the case to the leaders of the district party Committee, the government and the municipal public security bureau. The leaders of the district party Committee, the government and the municipal public security bureau attached great importance to the case and instructed the Linhe District Public Security Bureau to carefully organize and deploy, find the right time, and strive to catch all its key members. Immediately, the public security organs at the two levels in the urban area set up a task force on "Cracking down on Gangsters’ Crimes", with Jia Yingxiang, director of the urban area bureau, Su Yong, deputy director of the urban area bureau, and Liu Jingang, director of the regional bureau as deputy heads, Li Jun, political commissar of Linhe District Public Security Bureau, Zhang Yongping, deputy director, and Tao Fazhi, the police force at the two levels in the urban area, totaling more than 100 members, to fully solve the case.

　　According to the instructions of the leaders, the task force organized a lean police investigation to master the activities and characteristics of the gang. On December 24, 2009, the investigation by the task force learned that the main leaders of the "skinhead gang" and most of the key members of the gang will meet in the two entertainment cities of "0478" and "San Diego" on Christmas Eve. After the district bureau reported the situation to Director Jia Yingxiang, the public security organs at the two levels in the city thought that the time had come to arrest, and resolutely decided to adopt the method of centralized police use to arrest the gang. In order to create conditions for the arrest, the Municipal Bureau specially deployed the "Winter Fox Hunting" to carry out a unified city-wide inventory operation on the same day, and the city’s police force carried out inventory and rectification of entertainment places. The regional bureau made detailed arrangements in accordance with the instructions of Director Jia Yingxiang. The task force secretly formulated the best arrest plan, surveyed the action route and refined the arrest measures. Under the condition of strict confidentiality, the task force scientifically divided more than 600 police officers at two levels in the urban area into arrest group, alert group, on-site standby group, peripheral control group, traffic control group and other working groups, and each group was clearly divided. At 9 o’clock that night, Director Jia Yingxiang of the Municipal Bureau and Director Liu Jingang of the Regional Bureau came to the scene to direct, and all the police officers who participated in the war arrived at the arrest position on time. In a lightning-fast manner, they quickly launched a centralized arrest operation, arresting 34 key members of the gang of "skinheads" in two entertainment cities, "0478" and "San Diego", and collecting 21 controlled knives such as daggers and machetes on the spot.

　　 After most of the main members of the gang were arrested, the task force immediately set up a hunting group, an interrogation group and an investigation and evidence collection group to refine their responsibilities and carry out their work. The pursuit team took many measures at the same time, fixed personnel, fixed time and fixed responsibility, carefully designed the pursuit action, and made full efforts to arrest. It successively traveled to Shanxi, Qinghai, Wuhai, Baotou, Ordos, Wuyuan, Hanghou, Dengkou and Qianqi, with a journey of more than 20,000 kilometers, and arrested 55 people involved in the organization’s escape, which laid a solid foundation for the smooth investigation and arrest of the case. After investigation, the task force learned that Zhao Guang, the leader of Haotianshe, might be hiding in Xining City, Qinghai Province, and sent a pursuit team to Xining to arrest him. After careful arrangement, the hunting team learned that there were several people from Inner Mongolia staying in this private room in the Sanhe Hotel on Gonghe Road, most likely Zhao Guang and others. The pursuit team immediately monitored the hotel and waited in the pit. At about 17 o’clock on January 21, 2010, the pursuit team found that one of the three men who went out was very similar in physical characteristics to Zhao Guang. After confirming his accommodation room, he requested the Qinghai Provincial Public Security Bureau to assist in the arrest. The Public Security Department of Qinghai Province sent 15 policemen armed with live ammunition and formed three encirclement circles with the pursuit team, and captured three "Haotianshe" principals, including Zhao Guang, who was ready to fight with a knife.
　　 After the case of the "skinhead gang" gang was transferred to the stage of public investigation, evidence collection and trial, the project headquarters insisted on special projects, increased the trial offensive and made every effort to tackle the problem. Relevant leaders at the two levels in urban areas have listened to case reports many times and made important instructions. Jia Yingxiang, director of the Municipal Public Security Bureau, and Su Yong, deputy director of the Municipal Public Security Bureau, came to the front line to directly guide the police participating in the war to carry out the trial. The People’s Procuratorate of Linhe District gave strong support to the investigation of the case. On the second day after the concentrated arrest of the members of the "skinhead gang", Procurator-General Qi Pingxiang personally rushed to the District Public Security Bureau to understand the case, and sent eight professional and experienced prosecutors to intervene in advance to participate in the investigation of the case, guide the investigation and guide the handling of the case.

　　 Because most of the members of these two gangs have been dealt with by the public security organs, they have strong anti-investigation and anti-interrogation capabilities. To this end, the task force adjusted the interrogation strategy and focus in time. According to the idea of "detention in different places, centralized interrogation, different people, highlighting key points, internal audit and external investigation, and overall promotion", the key members of the organization were taken as the focus of review, and interrogation strategies such as detention in different places, disintegration, policy attack, and sincere influence were used to break the offensive and defensive alliance of gang members and force them to truthfully confess the facts of the crime. The police of the investigation and evidence collection team went to Shanxi, Wuhai, Baotou, Ordos, Wuyuan, Hanghou, Dengkou, Qianqi and other places to carry out a lot of investigation and evidence collection, comprehensively and fully collecting fixed criminal evidence and forming an evidence chain.

　　 Through the above measures, the timeliness and quality of case investigation and crackdown were ensured, and more criminal facts of these gangs were dug up. After a lot of work, it was initially found that the "skinhead gang" in Linhe area was divided into two gangs, namely "Eagle Club" and "Haotian Club". The two gangs swaggered around in public places of entertainment, beating innocent people for no reason, causing troubles, openly abducting and raping women, and forcing women to engage in prostitution, taking protection fees, lending money around Hu, illegally collecting debts for others, stealing and robbing money as their economic sources. Among them, the number of "Eagle Club" is more than 70, and its members are marked by bald heads and tattoos. It has certain management regulations. The gang is divided into four levels, with unemployed Zhang Xiongying as the boss, seven backbone members under it, and several small leaders under the seven backbone members. The small leaders control several members respectively. All members are pyramid-shaped, the organizational system is tight, the superior controls the distribution of interests at the lower levels, and the personnel level and structure are clear.

　　 There are more than 30 members of the evil gang of Haotianshe, whose members are marked by baldness and tattoos. The gang is divided into four levels, headed by unemployed Zhao Guang and libing, with five backbone members on the second floor and several small leaders on the third floor. Under the small leaders, members are controlled separately and instructions are passed step by step. There are strict rules for Haotian Society to join: first, it must be introduced by the internal staff of Haotian Society; second, it must unconditionally obey Zhao Guang’s instructions; third, it must not contradict the internal staff of Haotian Society; fourth, it must be approved by Zhao Guang in person before joining.

　　 At present, the task force has arrested 90 members of the skinhead gang, and has approved the arrest of 57 people, criminal detention of 12 people, bail pending trial of 11 people, and other handling of 10 people. After the trial, gang members confessed that 169 crimes had been committed in Linhe, Wuhai, Erdos, Wuyuan, Wuqianqi, Zhongqi and Houqi since 2008. At present, the police have verified 111 cases involving ten crimes. Among them: 7 cases of intentional injury, 2 cases of affray, 56 cases of affray (16 cases verified), 6 cases of intentional damage to public and private property (4 cases verified), 2 cases of forced prostitution of women, 1 case of illegal detention, 5 cases of extortion, 63 cases of theft, 4 cases of robbery and 23 cases of rape (7 cases verified).
　　 In the 23 rape cases confessed by two gangs of evil forces, none of the victims reported the case to the public security organs because of the criminal suspects’ arrogance. However, in some cases of picking quarrels and causing troubles, some owners of entertainment places are afraid to take revenge and dare not report the case to the public security organs. Instead, they solve it by paying protection fees and settling it privately, which, to a certain extent, encourages the arrogance of these two criminal gangs. In view of this situation, the police of the task force patiently and meticulously did the ideological work of the victims under strict confidentiality, dispelled their ideological concerns and truthfully stated the case, which laid the foundation for severely punishing the crime.

　　 After the organized criminal gangs of the "skinhead gang" were smashed, the number of cases in Linhe City dropped significantly, especially the cases of fighting, trouble-making and extortion in the society decreased significantly. Netizens were very supportive of the actions taken by the public security organs and posted highly praises. Some owners of entertainment venues sent pennants and thank-you letters to the task force specially. The people applauded the smashing of the "skinhead gang" and thanked the public security organs for killing the people. The successful destruction of the gang of "skinheads" and evil forces fully demonstrated the position and ability of public security organs to crack down on evil forces and protect the people, deterred and contained crimes, stabilized the people’s hearts, purified the social security environment in the whole region, demonstrated fairness and justice, and achieved good legal and social effects.

　　 The case is still under further investigation. The police are telling the fugitive suspects to rein in from the brink and surrender themselves, and the political and legal departments will be lenient in accordance with the law. If you persist in absconding and endanger society, you will be severely punished by law. At the same time, the police called on the people and insiders to actively report and expose the illegal and criminal facts of the "skinhead gang" and the hidden clues of the fugitives. The police will reward those who have made meritorious deeds in strict confidentiality.

　　 Moderator Jia Jie:Next, please invite Jia Yingxiang, secretary of the Party Committee and director of the Municipal Public Security Bureau, to introduce the ideas and ideas of cracking down on evil in our city in the coming period.

Jia Yingxiang, Party Secretary and Director of the Municipal Public Security Bureau, made a press release.

　　 Publisher Jia Yingxiang: Hello everyone! First of all, on behalf of the Party Committee of the Municipal Public Security Bureau, I would like to extend a warm welcome to all the guests and friends in the press who came to attend the press conference, and express my heartfelt thanks to all of you for your long-term concern and support for the city’s public security work!

　　 Just now, Liu Jingang, director of the Public Security Bureau of Linhe District, gave a briefing on the detection of the gang of "skinheads" and evil forces. After listening to it, it was really shocking. The number of people involved in the gang was as high as 126, and violence was the main means. They fought with open fire, ran roughshod over, committed crimes, oppressed the people and harmed one side. For the benefit of the gang, even for a small matter, they go to war, fight bloody battles, resort to brutal means, recklessly, openly challenge the law and undermine social order. The gang has committed 169 crazy crimes, including more than 10 charges of intentional injury, rape, robbery, forcing women to engage in prostitution, illegal detention, theft, affray, extortion, intentional destruction of property, etc. The nature is bad, the means are brutal, and some plots are simply insane. The gang’s serious crimes not only disrupt the social production and life order in our city, but also pose a serious threat to social security, and seriously endanger the safety of the people and the peace and stability of society. The people hate this, and the victims hate them even more, but they are afraid of arrogance, violence, and fear of being hurt and retaliated. They dare to be angry and dare not speak, dare to be angry and dare not argue, often talk about black and hate, and even dare not report the case.

　　 The detection of the case was carried out with the strong leadership support of the Party committees, governments and political and legal committees at the two levels in urban areas, the joint efforts of public security organs at the city and district levels, and the close cooperation of various police types. After more than three months of hard work and careful investigation, the police handling the case destroyed the "Eagle Society" headed by Zhang Xiongying and the "Haotian Society" headed by Zhao Guang, which is also known as the "skinhead gang". This is the largest organized crime case with underworld characteristics successfully investigated by the public security organs in our city, and it is also the case in which the public security organs in our city have destroyed the most members of criminal gangs, involved the most cases and committed the most kinds of crimes over the years. The successful cracking of the case and the arrest of key members can be said to be a great joy to the people and a great boost to their hearts. The people clapped their hands and told each other, giving firm support and high praise through the internet and thank-you letters. The success of the case has dealt a severe blow to the arrogance of the evil forces, severely deterred all kinds of illegal and criminal acts, effectively curbed the breeding and spread of the evil forces and many public security problems caused by them, played a groundbreaking role in the long-term stability of the city, and demonstrated the majesty of the law and the strong strength and strong determination of the public security organs to crack down on crimes and protect the people.

　　 In the process of detecting the case, the police handling the case at the two levels of public security organs in urban areas hold high the banner of loyalty and victory, sharing common enemy and being selfless and fearless; Hard work, no regrets, always with high fighting spirit, full enthusiasm, rigorous style, fighting day and night in the workplace, for nearly three months without rest, made extraordinary efforts and outstanding contributions, laying a solid foundation for the detection of the "skinhead gang" criminal gang case. In order to further boost morale, inspire fighting spirit and arouse vigilance, we will hold a special summary and commendation meeting to reward those who have made meritorious deeds in solving crimes.

　　 By detecting the criminal gang case of "skinhead gang", we are soberly aware that the criminal harm degree and social harm consequences of black and evil forces are much more serious than those of ordinary criminal crimes, and we have accumulated a lot of valuable experience and gained many useful inspirations in the detection of the case, which has strengthened our confidence and determination to fight against black and evil forces. At present, we are still in a period of prominent social contradictions, high incidence of criminal cases and complicated struggle against the enemy. Crimes committed by evil forces, economic crimes involving stakeholders, Internet crimes, crimes against intellectual property rights, and crimes of producing and selling fake and inferior agricultural materials have intensified, which has brought new challenges to public security organs in maintaining social order and stability. We should always maintain the trend of cracking down on serious criminal crimes, further deepen the special struggle to crack down on gangs and eliminate evil, continue to adhere to the principle of "cracking down early and cracking down on small crimes and eliminating evil", adopt effective methods such as combining key investigations with unannounced visits, combining special intelligence with mass reports, comprehensively collect clues about all kinds of gangs and evil-related crimes, put them into the line of sight of cracking down on investigation in time, include them in the target of cracking down, and continuously carry out accurate and effective strikes. In order to further intensify the crackdown on evil forces and other criminal crimes, we should do a good job in the following tasks:

　　 First, strengthen coordination and linkage, and truly form a joint force. Under the strong leadership of the municipal party Committee and the government, we should mobilize all sectors of society and the broad masses of the people to take courageous actions to fight against evil forces and all kinds of illegal crimes, actively provide all kinds of clues and evidence, and support public security organs in investigating and solving cases. All departments and police of public security organs should cooperate with each other and work hard to form a joint force to crack down.

　　 Second, we must adhere to both the symptoms and the root causes. We should seriously study and grasp the trends and laws of crimes committed by evil forces, correctly analyze the evolution process and characteristics of crimes committed by evil forces, and take targeted countermeasures and measures in time to eliminate them in the bud at the first time. And fundamentally eradicate the breeding ground of evil forces, stifle their space for survival and development, and never let the evil forces that dominate one side exist in our city.

　　 Third, I sincerely hope that the broad masses of the people, especially the victims, will take the initiative to expose the illegal and criminal facts and evidence of the criminal gang of the "skinhead gang" and give strong support to the public security organs to severely punish these criminals. I solemnly promise here that the public security organ will keep the informer confidential and resolutely protect your safety.

　　 4. Through today’s press conference, on behalf of the public security organs, I am here to severely warn criminals who dare to break the law, immediately stop from the brink, stop committing crimes and voluntarily surrender. Severely tell the criminal suspect who is at large in this case to surrender to the public security organ as soon as possible, and strive for leniency, otherwise we will take hell to pay.　

　　 If evil is not eliminated, the people will be uneasy and the society will be unstable. It is a great historical mission and lofty political responsibility of public security organs to severely crack down on and eradicate crimes committed by evil forces to protect the fundamental interests of the people and maintain social harmony and stability. Here, on behalf of the city’s public security police, I solemnly promise to the people of the city: No matter how strong the economic foundation of the evil forces is, who is the backstage, and how crazy and vicious the criminal means are, we will give a devastating blow, completely destroy the soil where the evil forces grow and spread, and eradicate the survival foundation of the evil forces. Resolutely achieve the "three never allow": that is, the evil forces will never be allowed to act rashly and run amok; Never allow evil forces to take root and spread; The evil forces will never be allowed to sit on their feet and form a climate. I also sincerely hope that friends and guests in the press can, as always, care about and support the public security work in our city, publicize the achievements made by public security organs in cracking down on evil, mobilize people from all walks of life to expose clues about black and evil crimes, and actively create a good public opinion atmosphere in which the whole society participates in cracking down on evil.

　　 I believe that with the correct leadership of the Municipal Party Committee and the Municipal Government, the full cooperation of the procuratorial organs and the relevant departments of the courts, the support of the people of the whole city, and the extensive participation and supervision of all sectors of society, especially friends from the press, we have the determination, confidence and ability to maintain the long-term stability of Bayannaoer City and ensure the people’s livelihood and happiness!

　　 The Spring Festival is coming. On behalf of the Party Committee of the Municipal Public Security Bureau, I would like to take this opportunity to pay my respects to the people of the city, friends in the news media and the public security police in the city. I wish you good health, smooth work, happy family and all the best!

　　 Thank you!

　　 Moderator Jia Jie: Today’s press conference is over, thank you!

Adhere to the scientific spirit and oppose political manipulation.

On the afternoon of April 8, the State Council Press Office held a press conference. Shen Hongbing, deputy director of the National CDC and director of the China CDC, and relevant experts introduced the traceability research of COVID-19 in China and answered questions from reporters.

Politicize the origin of the new crown

Is intolerable to the scientific community in China.

Shen Hongbing, deputy director of the National CDC and director of the China CDC.It is said that more than three years have passed since the COVID-19 epidemic was discovered at the end of 2019. During this period, we have been continuously promoting the related traceability research. Tracing the source of Covid-19 is a very professional issue. The China government and China scientists have always maintained a scientific attitude, and they all hope to find out the source of Covid-19, which is of great significance to prevent similar epidemics from happening again.

First of all, as an open country, after the outbreak, we have always adhered to a scientific attitude on the scientific issue of traceability and actively communicated and cooperated with the World Health Organization. In response to the resolution of the 73rd World Health Assembly,Take the initiative to invite WHO to send an international expert group to China twice to carry out joint research on traceability.Adhering to the principle of "jointly working out the work plan, jointly conducting analysis and research, jointly writing the research report and jointly publishing the research results", the first phase of the joint traceability research was successfully completed in Wuhan, and the resulting "Tracing Research of SARS-CoV-2 in COVID-19 convened by the World Health Organization: China Part-WHO Joint Research Report" was fully recognized by domestic and foreign experts and WHO who participated in the research at that time.

Throughout the first phase of joint research,China provided the Joint Expert Group with all the traceable information at that time, and did not conceal any cases, samples and their testing and analysis results.Recently, some WHO officials and experts have expressed their opinions at will and rashly denied the results at that time, which is totally contrary to the scientific spirit, rude and disrespectful to scientists from all over the world who participated in the early traceability work, and a manifestation of politicizing the traceability of the new crown, which is intolerable to the scientific community in China and unacceptable to the global scientific community.

Second, on the basis of the huge human, material and financial resources invested in the first phase of joint research, we have not stopped tracing the source of Covid-19, but still pooled resources to continue to carry out comprehensive scientific investigation and research work in epidemiology, molecular epidemiology, animals and environment and even laboratory inspection. The relevant progress and conclusions have also been shared with the international scientific community and peers by Chinese scientists through the exchange of reports with WHO and SAGO, or by publishing articles. Numerous research findings have further confirmed the results of the first phase of joint research.

Shen Hongbing said,We advise the people concerned in the World Health Organization to return to a scientific and just position, and not to take the initiative or be forced to become a tool for individual countries to politicize the origin of COVID-19.

Respond to the accusations of individual WHO officials

Scientists say they feel "surprised" and "sad"

In response to the accusation of individual WHO officials that the China government’s release of COVID-19 data has not been open and transparent, which has affected the global traceability research of COVID-19,Zhou Lei, researcher of China CDC.He said that as a Chinese scientist who personally experienced the first phase of joint traceability research, "I personally feel quite surprised."

She explained that, because in fact, in Wuhan at that time, we jointly studied scientists, including foreign and domestic joint expert working groups, and in the process of joint traceability research, Chinese scientists shared all the data and materials we had, including the early case information, and the case information of more than 76,000 people with possible and suspicious Covid-19 infection in Wuhan at that time, in a scientific, open, objective and transparent working principle.

In addition, at that time, more than 38,000 samples of poultry and livestock and more than 41,000 samples of wild animals collected in China from 2018 to 2020 were tested for antibodies or nucleic acids. These results suggest that Covid-19 is not positive. We also investigated the upstream and downstream supply chains of all animal products in South China seafood market at that time, and found no evidence of virus spreading among animals. These research results were shared with the international expert team selected by WHO at that time, and everyone recognized them.

In the first stage of joint traceability research, we also considered the possibility of laboratory leakage in the design stage with a scientific and comprehensive attitude. In order to study this aspect, during our stay in Wuhan, we organized a joint team of experts to investigate and study in many laboratories in Wuhan, and conducted in-depth exchanges. Moreover, we also investigated and analyzed all the health monitoring data and possible clinical data of laboratory staff, including students who were in the laboratory at that time. In every way,In the first stage of joint traceability research, we fully shared our research results and data without any concealment or reservation.

Zhou Lei also said that after the release of the traceability report of the first phase of the early joint research, it was widely recognized, including WHO and international counterparts. But I don’t know why there is a questioning voice now. "This is also what makes me feel sad."

She emphasized that both Chinese scientists and top international experts selected by WHO worked very hard in the first phase of joint research, working day and night. We have got such a joint research report with great scientific value, which deserves due respect, and should not be denied or blamed. So I suggest that you still adhere to the attitude of scientific traceability, orWe should continue to adhere to scientific traceability, and we should devote ourselves to the next stage of work together, and stop blaming and suspecting each other, which will not help us to find out the origin of the virus.

Zhou Lei bluntly said that WHO is very important. It is an authoritative professional organization recognized by the international community, and its scientificity, rigor and impartiality are beyond doubt. Now I put forward the view that "if we make such accusations, especially if we want to deny the results of our first-stage joint traceability investigation, I am afraid it will damage the credibility of WHO."

There is not enough evidence to prove that raccoons are the source of virus transmission!

According to the viewpoint that raccoons or Covid-19 are the intermediate hosts in South China seafood market in China,Tong Yigang, Dean and Professor of beijing university of chemical technology Life College.In response, he said that some new experimental data recently found the raccoon dog, but now there is far from enough evidence to prove that it is the source of the virus. Many people hope to find the chain and evidence (the source and spread of Covid-19), but we are the same. We very much hope to find out where the source of the virus really is. Scientists in China and many parts of the world are doing this. But just from the data in this article, it is not enough, it is far from it.

Tong Yigang said that there was an article in China earlier that some animal samples were found in the early environmental samples of COVID-19, which were more human samples, as well as other samples of chickens, pigs, dogs, cats and various birds. In fact, these animal samples were far more than raccoon dogs. From this point of view alone, it is not enough.

In addition, at that time, a large number of specimens were measured in South China seafood market, including hundreds of animal specimens, and no animals were found to carry Covid-19. It is not enough to infer evidence from the environment to find animal samples. In addition, for example, the virus sequence we found in the environment is actually almost 100% identical to the sequence of the patient who was ill at that time, which also suggests that the samples in the environment are likely to come from people, not animals, and there is a lot of evidence.

At that time, the sequence of raccoon dog existed in many negative specimens in the environment, and even the sequence of raccoon dog in this specimen was more than that of the positive raccoon dog, but there was no sequence of this virus in the negative specimens, and it was difficult to explain why the virus must have originated from raccoon dog. Besides, even if raccoons are infected, there are many people infected with this disease in the seafood market in South China. It is entirely possible that people have polluted the environment or infected raccoons. Even if raccoons are positive, there is still this possibility. Therefore, I think it is not rigorous and scientific enough to draw such a conclusion based on the current little data.

Now Chinese scientists and experts believe that

What is the most likely origin of COVID-19?

Zhou Lei explained that regarding the origin of Covid-19, we had reached a conclusion during the first phase of joint research, and this conclusion was fully displayed in the joint research report jointly published by us and WHO at that time. In the report, we clearly put forward the results of hypothesis research on several aspects of the origin of the COVID-19 epidemic. Let me reiterate this conclusion: the possibility of zoonotic diseases spilling directly is "possible to probable", and we think it is "probable to very probable" to introduce them through intermediate hosts, "possible" to introduce them through cold chains, and "extremely impossible" to introduce our research judgment through laboratories.

After finishing the first phase of joint traceability research in Wuhan, we did not stop studying, but continued to carry out a lot of research work according to the work plan and suggestions for the next phase formulated in Wuhan at that time. All kinds of research results also confirmed our research conclusions in the first phase in Wuhan, and we have not changed our judgment until now.

Tong Yigang said,At present, there is no scientific basis to clarify the real origin of Covid-19.There are positive samples in the seafood market environment in South China, and most of the host information detected in these samples is human information, as well as other animals’ information, which also suggests that the cases in the seafood market in South China are probably from people, not from animals in the seafood market. How, where and how did Covid-19 infect people? This needs further study.

CCTV News:Carrier-based aircraft is the main combat equipment of aircraft carrier, and carrier-based aviation unit is the core of aircraft carrier combat effectiveness construction. Tomorrow (May 10th) is the 10th anniversary of the establishment of the naval carrier-based aviation unit. At the beginning of today’s program, please follow the reporter and go to the only military school in the whole army that is responsible for training carrier-based aviation personnel — — Take a look at the Naval Aviation University.

What you see now is the daily picture of this university. It is a training base for aviation and coastal defense personnel, and has trained tens of thousands of technical personnel such as flight, command and staff officers. It is one of the 13 key construction colleges of the whole army. Soaring in the sky and dreaming of deep blue, we followed the reporter’s lens into the Naval Aviation University.

This is a base of Naval Aviation University. Among the flight students who graduate every year, only a few students meet the strict requirements for flying carrier-based fighters. Not long ago, a new group of flight students successfully completed the J -15 solo mission, adding new strength to the carrier-based fighter team. Next, they will carry out the qualification certification on the aircraft carrier and fly to the farther deep blue.

As an institution for training naval aviation talents, air crews with special aircraft are also the key direction in the talent training system of the school.

CCTV reporter Zhang Yixiao:Here is an airport of Naval Aviation University. Behind me is the air police 200H early warning aircraft. It can be seen that the graduating air combat cadets are about to practice in the cabin. By being familiar with the equipment operation process, they can improve their operation skills and enhance their post-holding ability in the future.

Air combat personnel are an important part of air information combat forces, and they mainly complete various reconnaissance and early warning tasks through airborne detection equipment.

Practice in learning, learn in practice. In the teaching system of Naval Aviation University, a number of clubs have been set up, and students can learn more about flight and understand it by making model airplanes and crossing planes themselves.

CCTV reporter Zhang Yixiao:At this moment, the flight students beside me are going to use these model planes they made to carry out flight tests. Although we seem to be just flying, they have applied the knowledge of flight principle, aircraft structure and system they learned in class in the design and production of these model planes.

Yang Zijiang, faculty member of Aviation Foundation College of Naval Aviation University:By making an airplane (model airplane), students’ cognition of the whole airplane will be raised to a higher level, and by flying an airplane, students’ cognition of flying will also be raised to a higher level. Compared with our college, the average success rate of all flight students is 20% higher than the average level of those who have participated in model airplane training.

Teach for war and walk for war. In addition to consolidating theoretical teaching, there are courses such as flight simulator and pilot three-degree-of-freedom rotation training in the syllabus.

Flight students will bring what they can’t understand in the theoretical class to the simulated flight classroom for simulated flight training, and solve the problem through practical operation.

In order to speed up the completion of the transformation task and build a perfect talent ability model, Naval Aviation University has formulated a talent training program for carrier-based fighters, helicopter pilots, air combat personnel, etc., which has delivered tens of thousands of outstanding talents to the navy and become the cradle for sea and air eagles to dream of the blue sky.

Together with the previous dance floor and elderly activity center, it formed a "pocket" fitness square that benefited the nearby people. Photo by Bao Kangxuan (People’s Vision)

　　In recent years, Sihong County, Suqian City, Jiangsu Province has strengthened the construction of venues and facilities around the masses, improved the fitness function, opened it to the public free of charge, and strived to create a "15-minute fitness circle". The picture shows that a few days ago, the children of the super roller skating training class in Sihong County practiced roller skating in the Weishui Wetland Park.

　　With the improvement of people’s living standards, the national fitness enthusiasm is growing, and square dance, brisk walking and other sports are loved by more and more people. However, the noise disturbing people, venue disputes, traffic safety and other issues caused by this can not be ignored, which brings new challenges to urban governance.

　　How to meet the needs of public fitness while taking into account social order? As a city manager, on the one hand, the government should guide bodybuilders to abide by social order and establish a sense of rules; On the other hand, it is also necessary to increase the supply of public fitness space and focus on solving the problem of "where to exercise" for the masses.

　　Fitness should not affect others.

　　"It’s too painful to live in noise every day!" Liu Xiaoyun complained to reporters.

　　Throughout the year, it is not the alarm clock that wakes up Liu Xiaoyun, the office worker, but the square dance aunt who gets up early downstairs to exercise and the chorus uncle who practices singing loudly. Liu Xiaoyun told reporters that there are people dancing in the square dance and singing in his neighborhood every morning and evening. The sound is so loud that you can hear it clearly even if you close the window. What makes her headache even more is that her son in elementary school can’t do his homework with peace of mind every day, which is unbearable.

　　Why are public activities such as square dance so popular? Aunt Dong, who often dances square dance, told reporters: "Square dance is not difficult to learn. It can not only exercise, but also make friends. It is refreshing to come out and dance with everyone every day."

　　For this reason, more and more middle-aged and elderly people have joined the square dance team, but it has also brought problems such as noise and occupying the venue. Conflicts between square dance participants and surrounding residents have occurred frequently. The square dance was also confronted by throwing water bags and high-pitched guns upstairs, and even staged a fight, which not only brought harm to both sides, but also affected social harmony and stability.

　　Not only the square dance, but also the fitness activities such as running, whipping and playing top have been controversial. For example, the "runaway group" arbitrarily encroaches on motor vehicle lanes, ignores traffic lights, and affects traffic safety; Cyclists are crazy about "racing", shuttling back and forth on the sidewalk and accidentally hitting pedestrians; Whip-throwers dance like flies, making the surrounding fitness people jumpy … …

　　In this regard, Pang Jiulin, director of Beijing Chunlin Law Firm, said that road rampage and motor vehicle lane "racing" are not only uncivilized behaviors, but also suspected of breaking the law. According to Articles 31 and 61 of the Road Traffic Safety Law of the People’s Republic of China, no unit or individual may occupy roads for non-traffic activities without permission; Pedestrians should walk on sidewalks, and those without sidewalks should walk by the roadside. According to Article 57 of the Road Traffic Safety Law of the People’s Republic of China, driving non-motor vehicles on the road should comply with the relevant traffic safety regulations, and non-motor vehicles should drive in non-motor vehicle lanes; On the road without non-motor vehicle lanes, you should drive on the right side of the roadway.

　　"Exercise is understandable, and everyone should participate, but personal interests should not be based on the distress of others and interfere with the normal life of others." Yang Hongshan, a professor at the School of Public Administration of Renmin University of China, said.

　　Combining rigidity with softness to solve the problem of disturbing people

　　"It’s not that I haven’t complained, but it has been ineffective. When the managers came, they could only persuade the dancers to turn down the music, and when they left, the sound was loud again. " Liu Xiaoyun said helplessly.

　　Yang Hongshan believes that the uncivilized phenomenon of public fitness is frequent, and one of the important reasons is the lack of rules and regulations for uncivilized behavior. The existing norms are not clear enough. "Where and when to dance in square dance, what rules to follow, and the level of sound, even if it disturbs the people, who will coordinate and who will supervise, should have clear regulations."

　　In fact, in recent years, the governance of "disturbing people’s fitness" such as square dance has been strengthened. In 2017, the Notice on Guiding the Healthy Development of Square Dance Activities issued by the State Sports General Administration stipulated that the noise generated by square dance fitness activities should not affect the surrounding students’ classes and the normal life of residents. On August 17th this year, the Law on the Prevention and Control of Noise Pollution in People’s Republic of China (PRC) (Draft) was submitted to the 30th meeting of the 13th the National People’s Congress Standing Committee (NPCSC) for deliberation, and the existing law was revised, and it was proposed to punish the noise disturbing people in public places.

　　Wang Yi, an expert from the Expert Committee of the Ministry of Housing and Urban-Rural Development, said that the relevant laws are not perfect at present, and he suggested that a law on the management of urban public spaces should be formulated to restrict the behavior of urban public spaces.

　　After the specification is clear, it needs to be implemented more forcefully. "The current law enforcement needs to be strengthened. If we can establish a more professional urban management team and increase the law enforcement of behaviors that affect the order of urban management, it will be of great help to reduce such behaviors." Wang Yi said.

　　"Civilized urban public space was not formed in a day. Punishment is not an end, and regulations alone cannot be done once and for all. " Yang Hongshan believes that publicity and education should be strengthened to guide people to establish a sense of civilization and improve their own quality.

　　"Legal education should start with dolls." Wang Yi believes that legal education should be strengthened from kindergarten and primary school, and the proportion and class hours of legal courses should be increased, so as to enhance the public morality of the whole people and form a self-discipline atmosphere in the whole society that does not cross the border and affect others.

　　In addition to hard law enforcement, there are also many places that try to use technical means to solve such problems skillfully.

　　Recently, the smart square dance system installed in Shanghai Minhang Gumei Population and Culture Park has been well received by nearby residents. The system uses directional sound technology to control the sound propagation range within the included angle of 30 in front of it. The sound in the directional area is clear, but the sound on the side and back decreases rapidly. The sound that is vaguely similar to the "buzzing" of mosquitoes is heard at the side 70 meters or the back 50 meters. In order to strictly control the upward transmission volume and avoid disturbing the residents of nearby high-rise residential buildings, the grape trellis where the system is located is equipped with a ceiling.

　　Since its installation one month ago, the street office has received almost zero complaints from residents about square dance. A resident living nearby said: "After the ceiling is installed, the sound of square dance can hardly be heard at home."

　　More and more cities such as Beijing, Nanning, Chengdu, etc. have sprung up "silent square dance": without high-decibel loudspeakers, the whole square is quiet, and the aunts and grandmothers wearing wireless FM headphones move neatly and dance.

　　Reasonable planning of urban space

　　In the view of Zhang Shangwu, a professor in college of architecture and urban planning, from the disturbance of square dance to the occupation of roads by "mobsters" and "bikers" all reflect the contradiction between the supply of public services and the demand for national fitness.

　　Li Jia, a cycling enthusiast, is often troubled by the difficulty in finding a venue suitable for cycling and fitness. "Bicycle lanes on many roads are very narrow. In many places, bicycle lanes and car auxiliary roads are mixed, and electric cars and pedestrians often appear on bicycle lanes, which is very unsafe." Li Jia told reporters.

　　According to the data released by the State Sports General Administration, by the end of 2020, there were 3,713,400 sports venues nationwide, covering an area of 3.099 billion square meters, with a per capita sports venue area of 2.20 square meters. This has improved compared with previous years, but it is still far below the level of neighboring countries such as Japan and South Korea, and there is a big gap in outdoor sports infrastructure.

　　"This is not unrelated to China’s past urban construction standards and construction concepts." Zhang Shangwu pointed out that in the past, urban planning and construction mainly focused on the traffic function of streets, but paid insufficient attention to the slow traffic and daily life functions and activities, and the residents’ daily fitness space was insufficient. In modern urban life, streets are increasingly endowed with multiple roles. An ideal street is not only an infrastructure for vehicles and pedestrians, but also an important space carrier for urban life and public activities. The new street space design should adapt to the new social needs.

　　In this regard, many experts interviewed by the reporter said that it is necessary to work hard in increments, increase the supply of fitness venues, open up some sections for sports enthusiasts, and designate special fitness venues.

　　From the Healthy China Action (2019— 2030), to Opinions on Strengthening the Construction of National Fitness Facilities and Developing Mass Sports, National Fitness Plan (2021— 2025) and other documents have been issued. In recent years, the state has continuously introduced relevant policy guidelines to promote the creation of a "15-minute fitness circle" and fully solve the problem of "where to exercise" for the masses.

　　Recently, the National Development and Reform Commission organized and implemented the short-board project of national fitness facilities, and arranged for the central budget to invest 2 billion yuan to support 177 public service facilities projects in sports parks, national fitness centers and public stadiums, including standard track and field runways and standard football venues, social football venues, fitness trails and outdoor sports.

　　Zhang Shangwu said that the redistribution of public activity space should be carefully calculated, and the rational use of public space should be guided and the potential of space resources should be tapped and integrated through urban planning and legal construction. "For example, we can integrate the internal space of some units with the urban space, and coordinate the playgrounds and small green spaces within some schools, enterprises and institutions to be open to the public for use in a specific period of time, so as to improve the efficiency of space utilization. Of course, this is inseparable from the improvement of the city’s refined governance capacity. " Zhang Shangwu said.

　　Revitalize Kugaji, marginal land and other resources, and plan to build multifunctional sports fields, sports parks, fitness trails and stadiums that are close to the community, accessible and open to the public … … Everywhere is already in action. Beijing will open bicycle lanes, build 36 kilometers of community hiking trails in 2020, and complete the comprehensive management of 378 kilometers of slow-moving systems; Chengdu issued the first "Guidelines for Setting Sports Space at Home" to promote the implantation of sports facilities in "Silver Corners in Phnom Penh" such as old factories, roof spaces and spaces under bridges, and 50 "Community Sports Corners" at home will be built this year; Jiangsu has accelerated the construction of sports parks, and has built more than 1,300 sports parks covering urban and rural areas, with a per capita public sports area of 3.15 square meters … …

　　I believe that with the joint efforts of all parties, people with different sports needs can have somewhere to go, and "where to exercise" will no longer be a difficult problem.

Have you ever seen a "magic medicine" in your parents’ circle?

An eye drop that claims to "delay myopia"

Some people buy it and some people go to online hospital to buy it.

There are even people who make it themselves.

Low concentration of atropine (0.01% atropine sulfate)

Is it an IQ tax or does it work wonders?

1. What is atropine?

Atropine is a classic old medicine. As an anticholinergic drug, it has a variety of pharmacological effects, which can help detoxify and relieve gastrointestinal spasm when pesticide poisoning occurs. Its clinical application in ophthalmology mainly includesAt present, the mydriasis of paralytic ciliary muscles is mostly used in optometry for children and adolescents.Slow mydriatic agentUse.

The earliest research on the prevention of myopia by atropine was conducted in Singapore. The research confirmed that low concentration of atropine (0.01% atropine sulfate) can inhibit the axial growth caused by myopia and delay the rapid progress of myopia.　

2. How hot is atropine?

Strabismus and pediatric ophthalmology in Xiamen Eye CenterXie RenyiThe deputy director said that every time he went to the outpatient clinic, at least three or five parents came to consult about the low-concentration atropine eye drops. There were many children who had used them for two or three years, mostly aged 7 to 9. An ophthalmologist in Xiamen has been using low-concentration atropine for her daughter for four months, and many "little glasses" among her classmates are using the same eye drops. According to foreign media reports, many parents all over the country went to Shanghai specially to prepare a low-concentration atropine eye drop for their children.

3、Atropine is not officially listed.

It should be noted that low concentration atropine eye drops have not been officially listed in mainland China.In fact, it is not easy to buy low concentration atropine eye drops. Many parents buy hospital preparations from China, Taiwan Province and Singapore, and some parents buy hospital preparations from individual hospitals in China through friends. These are not drugs that have been approved by the state for listing.

Deputy Director Xie Renyi introduced,A drug can only be listed as a new drug after the clinical verification stage is over and the expert review is passed.Although the current clinical evidence shows that low concentration of atropine eye drops has a certain effect on myopia prevention and control, domestic ophthalmologists have not yet reached a complete consensus on the long-term side effects and potential complications.

4. Can I use atropine?

Deputy Director Xie Renyi stressed: "This kind of eye drops is a kind of medicine, not suitable for everyone. It is most important for children to cultivate scientific eye habits and increase outdoor activities.This eye drop is an unlisted drug, so abuse is not recommended. "

5, blind abuse is not desirable

Xie Renyi, deputy director, said that many parents will buy atropine, and even some will make it themselves. not to mentionThere are also risks such as improper drug concentration, unstable ingredients and contamination of pathogens, which affect the comfort of eyes and cause damage, and may bring unexpected side effects.

In addition,People who are allergic to atropine are not suitable for use!For example, after use, symptoms such as blurred vision and photophobia may occur. Moreover, low concentration of atropine is not effective for all myopia patients, and the literature reports that there is a non-response rate of 10%-15%, that is, it does not work. In addition, some children will have allergic symptoms such as local itching and low fever.

Deputy Director Xie Renyi said that the prevention and control of myopia should be treated according to the actual situation of patients. Effective control is that myopia progresses within 50 degrees a year, and if it is above 75 degrees, other intervention methods or joint intervention can be considered. "Children who are using low concentrations of atropine must come to the hospital every three months." He said that this follow-up is to check the intraocular pressure, pupil, eye surface and eye adjustment function to ensure the health of medication.

if it isBlind use of glaucoma or other hidden diseases will aggravate the condition.. According to media reports, a 7-year-old child in Hangzhou is 100 degrees short-sighted. His father dripped low-concentration atropine every night, but when he went to check again, he found that the child’s intraocular pressure increased. The doctor said that if the intraocular pressure remained at a high level for a long time, it would damage the optic nerve.

In addition, Deputy Director Xie Renyi also reminded that although the concentration is low, it is stillSome children may have a rebound in myopia after stopping using this eye drop.For example, during the medication period, the original annual increase is controlled within 25 degrees. After stopping the drug, the degree may suddenly increase too fast in one year. If it exceeds 75 degrees in one year, you should consult a doctor immediately.

Scientific prevention and control of myopia

Want to play < combination boxing >

1. Pay attention to eye habits

1 Use less electronic products: Babies under 2 years old should not watch TV, computers, mobile phones, ipad and other electronic products. Babies over 2 years old should not use electronic products for more than 30 minutes every day.

② Follow the "20-20-20" eye protection rule when using eyes at close range.

Remember to keep "one punch, one foot and one inch" when writing and reading.

2. Do more outdoor sports.

Two hours of outdoor activities every day can effectively prevent myopia. Sunlight irradiation can stimulate the secretion of dopamine, which plays a positive role in preventing and controlling myopia.

3. Go to bed early and get enough sleep.

The results show that the later the time, the higher the incidence of myopia. It is best for children to go to bed at 8:30 in the evening and go to bed early to ensure adequate sleep time. Only after a good sleep can the muscles around the eyes (eyes) be completely relaxed, which is conducive to using the eyes the next day.
The American Academy of Sleep Medicine (AASM) gives the best sleep time for infants and adolescents:
4-12 months: 12-16 hours; 1-2 years old: 11-14 hours; 3-5 years old: 10-13 hours; 6-12 years old: 9-12 hours; 13-18: 8-10 hours.

4. Regular vision screening

6 months: A baby born normally should go to the hospital for refractive screening at about 6 months. About 3 years old: start teaching children to know the eye chart, and check their eyesight and diopter regularly every 6-12 months. 6-18 years old: It is recommended to check your eyesight every 6-12 months, and children with glasses should undergo mydriasis optometry every 12 months.

5. Orthokeratology mirror (OK mirror)

OK lens is a kind of hard and breathable contact lens with reverse geometric design. It only needs to be worn when sleeping at night to maintain clear vision during the day. Long-term wearing can delay the development of myopia.

　　CCTV News:Since July, a number of new policies and regulations have been implemented. Let’s take a look.

　　China Youth Network, Beijing, October 21st "It’s not that I’m not sleepy. I just want to wait. As for what? I don’t know, I just want to wait. "This passage has become the mantra of many college students. And this "wait", most of them are brushing their mobile phones. So, how long do college students surf the Internet on their mobile phones every day? What are you mainly doing? Are you worried about network security?

　　Recently, China Youth Network Campus News Agency conducted a questionnaire survey among 1,220 college students around the country. The results show that more than 40% of students surf the Internet for more than 5 hours every day, and more than 80% of students surf the Internet mainly for social chat. Most students think that surfing the Internet by mobile phone makes mobile payment, information acquisition and social communication more convenient. Nearly 90% of students are worried about network security, and most students expect the network speed of 5G to be faster and more convenient for study and life.

　　The picture shows the proportion of college students’ mobile phone surfing time every day. China Youth Network reporter Li Huaxi cartography

　　Over 40% of students surf the Internet on their mobile phones for more than 5 hours every day, and over 80% of students mainly chat socially.

　　Wu Lin, a student of Sichuan Agricultural University, uses his mobile phone to surf the Internet every day for about 6 hours. "It has become my habit to brush my mobile phone when I wake up every day. Now surfing the Internet is a daily need. I feel that I don’t have much to do except surfing the Internet. I like chatting, watching news and playing games online when I have no classes. I can’t stop playing my mobile phone."

　　Like Wu Lin, there are not a few college students who have the habit of surfing the Internet for a long time. According to a survey conducted by a reporter from China Youth Network, 41.56% of college students spend more than five hours on their mobile phones every day. When surfing the Internet, 83.93% of the students mainly chat socially, followed by consulting materials and listening to songs, accounting for 62.46% and 58.61% respectively.

　　"I am deeply dependent on the Internet, partly because of my shortcomings in social skills." Joline, a student of Northwest Normal University, told reporters that she is introverted and unwilling to communicate face to face. She can express herself more directly and accurately online. She will keep a diary on the trumpet in Weibo, and what she is embarrassed to say in person can be expressed by WeChat. "Besides, I can also tell my story with strangers through Zhihu."

　　The picture shows the proportion of college students’ mobile phone surfing behavior. China Youth Network reporter Li Huaxi cartography

　　Mobile Internet access makes mobile payment, information acquisition and social communication more convenient.

　　So what convenience does mobile Internet access bring to college students’ daily life? In the survey, China Youth Network reporter found that most of the students interviewed thought that surfing the Internet by mobile phone made mobile payment, information acquisition and social communication more convenient, accounting for 90.25%, 80.49% and 78.52% respectively.

　　"Now you don’t have to bring cash when you go shopping. It’s really convenient to pay by QR code." Zhao Tingting, a student at Guilin University of Technology, said that it used to be troublesome to use cash for shopping. Now, with mobile payment, the mobile phone can scan the code to pay, which not only saves a lot of time, but also brings great convenience to life.

　　Chen Yixin, a student at Chengdu University of Information Science and Technology, told reporters that after going to college, she often chats with her parents online. "Sometimes I use WeChat videos, and it is very convenient to contact them anytime and anywhere even if I don’t go home." She also said that now she mainly watches news through Weibo and news apps, so she can keep abreast of the latest hot events, which is very fast.

　　The picture shows the proportion of convenience brought by mobile internet access to life. China Youth Network reporter Li Huaxi cartography

　　Nearly 90% are worried about network security, and most students expect 5G network speed to be faster and study and life more convenient.

　　Xie Wenyi is a student of Shandong University of Technology, and he attaches great importance to network security. "I have learned that bank card deposits may be stolen by clicking on the link to help bargain, which makes me very worried about network security." In order to avoid the disclosure of personal information, he will be more cautious when registering his account. He told reporters that many friends around him have fallen into the trap of online fraud, so they must strengthen their prevention.

　　The results of this survey show that 88.03% of the respondents are as worried about network security as Xie Wenyi. In addition to network security issues, 5G has also become a hot topic this year. When talking about the expectation of the 5G era, 87.38% of the respondents hope that 5G will make the network speed faster, and secondly, it will make the study and life more convenient and the video quality clearer, accounting for 86.64% and 71.31% respectively.

　　Hong Yumin studied in Hope College of Southwest Jiaotong University, and she needed to surf the Internet frequently for professional reasons. When talking about 5G, she said that 5G is a "good medicine" for architectural drawing. It doesn’t take a long time to download the software installation package, which greatly shortens the students’ drawing time. Compared with 4G, 5G is more stable and not easy to get stuck. When drawing, you don’t have to worry about network failure, which can guarantee the smooth birth of the work.

　　The picture shows the proportion of college students’ expectations for 5 G. China Youth Network reporter Li Huaxi cartography

　　Teachers in colleges and universities suggest that Internet surfing time should be arranged reasonably and network security protection should be done well.

　　Yang Mei, an administrative teacher at School of Information Engineering, Sichuan Agricultural University, believes that college students spend more time on the Internet than study time. Although this has become a common phenomenon, students are advised to pay attention to study. "At present, many students will become very anxious when they leave their mobile phones. In fact, students will make good use of the Internet to arrange their free time and pay more attention to WeChat official account and online classes related to their majors or employment, which will be helpful for future postgraduate entrance examinations or job hunting."

　　"Don’t easily click on pop-up web pages or unreliable advertising links shared by others, which are likely to contain viruses. When surfing the Internet in Internet cafes outside, don’t connect your USB flash drive, mobile phone and other things containing important personal information to your computer, which is easy to cause network security problems." At the same time, as the class teacher of the students, Yang Mei recommends students with poor self-control to use professional APP for entertainment time management, hoping that students can concentrate on their studies and focus on their studies.

　　This semester, Fan Yingjie, a teacher of Marxism College of Chengdu University, asked students to strengthen self-discipline, stay away from the internet at least half a day to one day in class and at ordinary times, and learn to control themselves. She hopes that through these ways, students can understand that instead of constantly paying attention to other people’s lives through mobile phones, it is better to live their own lives and do their own things in a down-to-earth manner.

　　Fan Yingjie also mentioned that regarding the issue of network security, the relevant state departments released a lot of warning case materials when promoting network security, hoping that students would learn more about it. "When using mobile phones or computers to surf the Internet, students should not randomly click unfamiliar links to avoid revealing personal information on the Internet, and try their best to do network security protection."

On March 8th, Wuhan Agriculture and Rural Bureau sent 1000 Jin of virus-free potato seeds to Wuhan Foreign Language School, and officially launched the natural labor practice activities for primary and middle school students in 2024. On the same day, students planted potatoes in the school labor practice base under the leadership of agricultural experts, spreading the hope of spring.

Zhu Hua, an agricultural expert and senior agronomist, told the children the story of potato introduced to China, demonstrated the growth pictures of potatoes in different periods, explained the skills of potato planting and maintenance, and led the children to dig, dig pits, plant seedlings and water … The students carefully planted potato seedlings in the soil, and they will grow under the careful care of the children.

According to the relevant person in charge of Wuhan Foreign Language School, since 2021, the school has carried out a series of labor ecological education courses with the theme of "practicing labor education and creating an ecological campus" to let children experience labor and gain happiness.

According to reports, Wuhan Education Bureau and Wuhan Agriculture and Rural Bureau organized 20 pilot schools, including Wuhan Foreign Language School, Wuhan Qiyi Huayuan Middle School, Jianghan District Wansongyuan Primary School, Wuhan No.4 Junior High School, Wuhan Erqiao Middle School, Hubei Wuchang Experimental Primary School and Optics Valley No.15 Primary School, to carry out labor practice activities of planting potatoes. Next, Wuhan will expand the labor practice of planting common crops to 100 pilot schools in the city. The education department will also work with the agricultural department to build a number of off-campus bases for natural labor practice. Through these activities, children can learn about "five grains" and practice "four bodies", cultivate patience and perseverance, learn to cooperate with others, and improve teamwork ability.

Wuhan Agriculture and Rural Bureau will give full play to the advantages of Academician Deng Zixin’s popular science studio team, agricultural technology experts and professional growers, and jointly promote a series of natural labor practice activities for primary and secondary school students with the education department, and guide primary and secondary school students to work and love labor through practical projects such as crop planting, maintenance, processing, picking, cooking, handicrafts and intangible skills.

Zhu Hua said: "Nature is the best teacher. Every child can release his nature here and know the natural laws of spring, summer, autumn harvest and winter storage through labor. The agricultural and rural departments are willing to care for the growth of children like watering crops."
