　　Zhongxin. com, Hangzhou, January 10 (Guo Qichen) In the daily life of fireworks, it contains peace and harmony; In the moment of emergency and danger, it highlights the step forward; At the intersection of the new and the old, there is a surge of innovation and reform … The "most beautiful" appearance of the people’s police is reflected in the retrograde charge at the critical moment and also reflected in the silent persistence of ordinary years.

　　January 10th is "China People’s Police Day", and the Zhejiang Provincial Public Security Department held a press conference to announce the "Most Beautiful Zhejiang Police" in 2021. Among them, there are the "most beautiful policemen" who care about the masses and catch up with the exam in the new era, the "most beautiful auxiliary police" who dream of police camp and fight side by side with the police, and the "most beautiful police sister-in-law" who is deeply attached to her husband’s career.

　　Different identities, different contributions, for the same cause, for the lights.

　　"Dispel evil and reunite love"

　　February 12, 2021, New Year’s Day. Li Xiaorong, director of Luoshe Police Station of Deqing County Public Security Bureau, Huzhou City, finished his work and went back to his mother’s house for a late "New Year’s Eve". When waiting for the red light on the road, I suddenly heard someone shouting loudly. Li Xiaorong, who has been a policeman for 24 years, immediately got off the bus and ran to the river.

　　In the cold river, a woman is struggling up and down. The water does not pass her head from time to time, and the woman’s position is in the deep water area in the middle of the river. The situation is very critical. Li Xiaorong didn’t think much, took off his coat and jumped into the cold river, struggling to pull the woman ashore.

　　When the medical staff and police officers arrived, Li Xiaorong squeezed the water on his clothes and left the scene silently.

　　This "guardian blue" is not only Li Xiaorong’s unswerving leap in the days of family reunion. Tong Lijian, the deputy commander of the patrol (special) police brigade of Chun ‘an County Public Security Bureau in Hangzhou, used his quick wits to hold the suspect’s sharp knife against the child’s throat with his bare hands in just a few seconds and quickly rescue him. It is also the life-and-death rescue of Fu Yingke, a policeman of the Criminal Investigation Brigade of the Public Security Bureau of Shengzhou City, Shaoxing, on the way of business trip, escorting intussuscepted babies for emergency medical treatment.

　　Keep evil behind you and let love reunite with the world. A group of Zhejiang police who light up the stars and help find relatives have made the realistic version of Lonely Lost have a perfect ending, making "not seeing" connected with "not leaving".

　　Sui Yonghui, a policeman from Xihu Branch of Hangzhou Public Security Bureau, who is known as the "Commander-in-Chief of Tracing People", implicated the blood ties scattered in the streets and helped more than 7,000 families reunite. Ke Weili, a policeman from the Criminal Science and Technology Office of Luqiao Branch of Taizhou Public Security Bureau, used forensic technology to decipher the "reunion password", which turned the "reunion" in the DNA library into a miracle on the road to finding relatives again and again.

　　"Different epaulettes, same faith"

　　In the public security team, there is a group of auxiliary police who also guard the safety of one side in the name of the police. They fight side by side with the police and jointly build a safe home.

　　In January 2021, Yao Forest, an auxiliary police officer of Renhuangshan Police Station of South Taihu New District Branch of Huzhou Public Security Bureau, was unfortunately injured by an exploded gas tank when handling a fire with the police. A burn photo is tearful compared with the previous one.

　　When the fire went out, Yao Senlin’s hair and eyebrows were burned away, and the original delicate face was burned beyond recognition. "I didn’t know what I had become at that time. Later, I took a selfie with my mobile phone and found that I was like a different person."

　　After only one and a half months’ rest, Yao Senlin returned to his post and put on his police uniform again. "Honor will eventually pass, and I will continue to protect the peace of this people." Yao Senlin, who was awarded the "most beautiful auxiliary police" this time, said.

　　Cross the sea, and you will show your true colors. Zhang Chong, an auxiliary police officer of Nanmen Police Station of Haishu Branch of Ningbo Public Security Bureau, bravely stepped forward in the face of the art knife suddenly pulled out by the suspect during an arrest.

　　In a dangerous situation where the neck cut by the suspect was as deep as 15 cm, Zhang Chong still held the suspect under control and arrested him with the help of his colleagues. After Zhang Chong was taken to the hospital, he was rescued with 240 stitches.

　　Looking at all public security fronts, there are Tang Wenjie, an auxiliary police officer who "descended from the sky" and bravely rescued the little girl hanging outside the balcony on the 11th floor, He Dawei, an auxiliary police officer who carried out anti-fraud propaganda at his wedding, and Lin Yi, an auxiliary police officer who used his computer technology to help trace the source of the epidemic …

　　They use the beauty of anti-epidemic, persistence, responsibility, serving the people and fighting for the people to interpret the "most beautiful" of the auxiliary police, either on the front line of anti-fraud, at the scene of solving crimes or at the window of handling permits.

　　"You protect peace, I protect you."

　　On February 25, 2021, Chen Chongke, a criminal policeman of Pingyang County Public Security Bureau in Wenzhou City, took the suspect to the hospital for a medical examination. Zhang Meila, his wife who was pregnant for six months, was waiting for a pregnancy test alone in her seat. Although her mood was a little low, Zhang Meila knew that her husband could not leave his post without leave, and advised him to work with peace of mind and insist on finishing the examination by himself …

　　In peacetime, the public security team is the team that gives the most and sacrifices the most. As police sisters-in-law, they are used to their husbands frequently working overtime and running around, and also guarding the peace of their home country with their own strength.

　　The epidemic situation was so fierce that one by one "police doctor families" stepped forward and went to the "epidemic" line. Zhu Ying, a respiratory physician at Wenzhou People’s Hospital, is the wife of Li Buhui, a policeman from Wenzhou Public Security Bureau. In early 2020, she was sent to Wuhan to fight the epidemic and became the first medical team member to aid Hubei in Zhejiang. In the 72 days of the expedition, she faced life and death to save lives, and her husband was on duty for a long time without taking a rest. The husband and wife became a couple of wars.

　　People’s teachers, medical staff, journalists, community workers … Among the 100 "most beautiful police wives", many people give full play to their professional expertise, support public security work with practical actions, and become veritable "good wives".

　　Xu Shuangshuang is the vice principal of Hangzhou Yucai Dengyun Primary School. Together with her police husband Wu Jianli, she created and published a series of children’s books "Mathematical Police" with the theme of "Mathematics+Anti-fraud", which was widely welcomed by young readers. Hua Xiaoxia, a reporter from Wenzhou Metropolis Daily, and Chen Mengyan, a traffic police husband, have been married for 12 years, and they have jointly planned to spread the "good voice" of the traffic police, calling on all sectors of society to further care for the public security police.

　　The "most beautiful policeman" cannot be separated from the understanding and support of the "most beautiful police sister-in-law". He shouldered the weathered Leng Yue of the public security front with iron shoulders, and she shouldered the daily necessities of family life with soft shoulders, jointly guarding the lights of thousands of families.

If the probability that two strangers meet and fall in love in the vast sea of people is very small, how likely are the two stars in the vast universe to meet and merge?

At the just-concluded American Astronomical Society, Larry Molnar, an astronomy professor from Calvin College in the United States, released an exciting news: around March 2022, two low-quality stars in the Milky Way will merge.

As soon as the news was published, it aroused strong public interest. After all, not many humans have the opportunity to witness the merger of two stars in their lifetime.

Where are these two stars? How far is it from us? What force created this shocking collision? How many years will the merger of these two behemoths last? Dinosaurs just witnessed the encounter between a comet and a planet, and they were almost wiped out. Then, five years later, when these two stars finally collided, what wonders will we witness? What impact will this collision have on our home planet Earth?

Let’s explore it in detail and do some homework in advance for this cosmic "encounter".

1800 light years away: long gestation and rapid merger

As you probably know, in our galaxy, there is a constellation Cygnus, and these two merging stars are in Cygnus. They form a star binary system called KIC 9832227, which is about 1800 light years away from us.

As early as January 2015, Professor molnar and others published relevant contents at the American Astronomical Society, and identified KIC 9832227 as a binary system that is likely to be merged.

They analyzed the data of this system from 1999 to 2014, and found that its cycle was continuously decreasing, and the decreasing trend was very similar to that before the outbreak of Scorpio V1309, and there was also a star merger event in Scorpio V1309. In 2015-2016, Professor molnar and others used further observation data to verify their previous inference, and finally confirmed that the system would be merged one day.

However, there are as many as 200 billion to 400 billion stars in the Milky Way, and nearly one third of them are located in binary or multi-star systems. It seems not uncommon for two stars in a binary system to merge.

Is this really the case? This requires us to understand the classification of binary systems first.

We can easily understand the "binary star system", that is, a system consists of two celestial bodies; These two celestial bodies can be ordinary stars or dense celestial bodies with high density, such as neutron stars or black holes.

In astronomy, we can classify binary systems according to many standards, one of which is the distance between two celestial bodies. For a "wide binary", the two celestial bodies are far apart and have little interaction. Two celestial bodies that are close to each other are called "close binaries", and it is possible for them to influence each other or transmit matter. Among the numerous binary systems in the Milky Way, there are only about 40,000 pairs of close binary stars, which can be said to be very rare.

Some close binary stars are too "intimate" and even come into contact, so we call them "contact binary". In an extreme case, the passing binary stars are so "close" that the two celestial bodies share the same external gas envelope. Generally speaking, it takes millions or billions of years for them to reach the stage of sharing the cladding, and once they enter the stage of sharing the cladding, the two stars will merge quickly, taking only a few months or years. Compared with the long years before sharing the envelope, the process of merger is like a blink of an eye, which is like a couple who have been in love for a marathon and then got married quickly after proposing marriage.

The binary star system KIC 9832227 mentioned above is in the final stage of shared cladding. According to the existing theoretical estimation, the two stars will merge in about five years.

The merger of binary stars will bring us a bright new star.

According to the current spectral data analysis, the mass of the two stars to be merged does not exceed 0.4 solar mass, which belongs to the category of the least mass stars we know. They look red, and the surface temperature is about two or three thousand degrees Celsius. Judging from the current observation, the two stars have not merged, and their apparent brightness is about 12 magnitude, which has completely exceeded the lowest limit that human eyes can see (6 magnitude), so we can only observe with the help of telescopes. (Magnitude is a unit used to measure the brightness of celestial bodies. The higher the brightness of stars, the lower the magnitude value; Sirius, the brightest star we see at night, is about 0 magnitude. )

The whole process of merging these two stars will last for several weeks, which is like a flash compared with their life span of 10 billion years. In this "instant", their brightness will rapidly increase by 100,000 times, and the apparent brightness can reach about 2 stars. It will look as bright as Polaris, second only to the three brightest stars we see in the northern sky: Sirius (-1 magnitude), Vega (0 magnitude) and Antares (1 magnitude).

The result of this binary merger is that there is a new bright star in our night sky for the time being, and its color is still red, so we call it "red star". This new star will exist for at least 10 billion years, so why do we say that there is a new bright star "temporarily"? Because it will only be bright for a few weeks, and then it will fade away and hide in the darkness beyond our naked eyes in the vast universe.

The gravitational wave generated by the merger of two black holes in 2015 attracted the attention of the whole world. So, will the merger of these two stars also generate gravitational waves five years later?

The answer is yes. The merger of binary stars will also release gravitational waves with a certain energy, but it is very small and almost negligible. Almost all the energy is concentrated in the electromagnetic wave, so we can only rely on traditional telescopes for observation. The gravitational wave observatory (LIGO) in the United States should not be able to detect this merger.

The merger of binary stars has brought us a bright new star. Will it also bring some dangers?

If we want to predict the impact of this event on life on earth, we need to know how much energy is released during the merger process and whether it will have any impact on the earth’s atmosphere.

There is no doubt that the merger of two celestial bodies will produce explosions and release a lot of energy at the same time, but the amount of energy released depends on the density of the merged celestial bodies. For example, the merger of two neutron stars will produce a so-called gamma-ray burst, which will release a thousand times the energy of a supernova in about 1-2 seconds and produce extremely strong gamma rays-astronomers have discussed the impact of such bursts on the earth-if such celestial bodies erupt at us not too far away in or outside the Milky Way, life on earth will be doomed.

However, we don’t have to worry that the merger of these two small stars will have any impact on life on earth. Compared with the merger of other dense celestial bodies, the energy released by the merger of these two stars is very small, even less than the energy generated by some normal stars, not to mention the energy generated by them is mainly in the optical band. We’d better watch the beautiful red star with peace of mind.

Standing on the shoulder of Scorpio V1309, waiting for the new star.

Theoretically speaking, astronomers always believe that the merger of low-mass binary stars is one of the cradles for the birth of slightly larger stars. However, the real observation has only made some progress in recent decades, which is attributed to the development of some large-scale astronomical survey projects and the improvement of computer processing power. In the past decades, astronomers have observed similar explosions many times, such as M31 RV in the Large Magellanic Cloud in 1988, V4332 in Sagittarius in the Milky Way in 1994, and V838 system in Unicorn in 2002-these explosions may represent merger events, but we are not completely sure.

It was not until 2006 that humans really confirmed a binary merger. The supernova search project of the Lick Observatory found the explosion of M85 OT2006-1 in the M85 galaxy 60 million light years away from the Earth. Astronomers from the University of California, Berkeley and California Institute of Technology made a detailed analysis, and found that the explosion originated from the merger of two low-mass binary stars, which was different from other known nova explosions. However, due to the lack of monitoring information before the outbreak, we are very lack of understanding of the binary system before the merger. In this year, according to the observations, astronomers gave a name to the new star formed by the merger of binary stars: "luminous red novae".

The key to really help astronomers solve the mystery of "Red Nova" is hidden in Scorpio V1309. This system was first discovered by astronomy enthusiasts in China and Japan, and then they submitted the relevant information to the astronomical variable source monitoring organization of the International Astronomical Union. However, the detailed data of Scorpio V1309 comes from an optical gravitational lensing experiment (abbreviated as OGLE；; Optical gravity lens experiment). The project was officially started by astronomers of Warsaw University in Poland in 2001. The original intention was to monitor a large area of the sky, hoping to find celestial sources with changing brightness and discover the phenomenon of gravitational lens, so as to test some celestial bodies, such as black holes, which were originally thought to constitute dark matter. The location of Scorpio V1309 is just within the monitoring sky area of OGLE, so astronomers have obtained a large number of long-term observation data before and after the outbreak. Subsequent data analysis not only confirmed that this is a "red nova" system (a system after the merger of two stars), but also provided us with more important information, that is, how this binary system evolved with time before the merger.

It is on the basis of observation data and modeling before the merger of Scorpio V1309 system that Professor molnar and others judged the system evolution of KIC 9832227, and predicted that the "close contact" between the two stars and the final merger would take place between September 2021 and September 2022.

Special feature of 1905 film network Not long ago, the film announced the second key extension, which triggered a hot discussion among netizens about the key extension of the film. Key extension is a way for film copyright owners to extend the validity of electronic keys, thus extending the film release time.

Looking at the domestic films with key extension, from the early days, only a few films choose to postpone the key every year, and now more than a dozen domestic films are postponed for screening every year. What are the doorways behind the doubling of the number of key extension films?

The earliest key extension in China can be traced back to "Crazy Stone" in 2006. A small-budget film can reach that box office at that time, which makes the whole market very excited. At that time in 2015, although the box office had reached a relatively high level, there were such strong imported blockbusters in the same year. monster hunt chose the key extension method and finally became the box office champion in that year.

In recent years, more and more movies have chosen to postpone their keys. In 2019, nearly 20 movies chose to postpone their keys. Nowadays, the key extension has become a hot search word in major schedules. For these movies, the key extension can increase the exposure and bring certain box office income.

The success of "monster hunt" is not a special case. At present, the top ten domestic movies in China have been extended with keys. Does this mean that key extension plays a decisive role in the box office?

Wu Yanyu, a film critic, said: "The decisive role is definitely not played, but for some films, there will still be a longer release cycle. For example, in The Battle at Lake Changjin, the word-of-mouth of the film continues to ferment after the National Day file, and even the box office grows very fast on weekdays, indicating that a large number of viewers know about the film’s release, but they haven’t had time to see it yet. At that time, the key extension time was quite long. The data showed that the final key extension time brought more than 300 million box office to Wolf Warriors 2, which still accounted for a certain proportion of the total box office of more than 5 billion. "

Interestingly, all the top ten domestic movies in China have been extended with keys, but this does not mean that the key extension is the decisive factor for them to become the top ten box office in film history, because these movies have their own basic discs at the box office, which makes the key extension play a role of extra points. When most filmmakers decide whether to extend the key, they will make a calculation of the box office trend. If the box office of the film is already in a relatively downward or even basically no state, there is no need to extend the key for this film.

Nevertheless, many filmmakers have made efforts and attempts. For example, this year’s very high-quality domestic animated film "Dick Pig" has been extended, and some other literary films have also made the same choice.

Wu Yanyu said: "According to the current data, the key extension obviously did not play a role in promoting the box office. On the other hand, if the cinema release time is extended, it means that the window period of streaming media on the film will be longer and the distribution cost of getting new media will be relatively reduced. According to different films, some art films may be released for a short time, and the audience’s word of mouth has not sunk into the audience that should be there. At this time, if you judge that there is still a chance to take a shot and try. "

The program interviewed the cinema manager and asked them about the key extension. Ou Bowen, general manager of Perfect World Co., Ltd. mentioned: "In theory, basically all movies can extend the key, but I personally think this is only suitable for high-quality movies. For example, The Battle at Lake Changjin’s key extension in the past two months is really a stimulus to the film market, which has been greatly improved. The current movie cycle should be week by week, and new movies are released every Monday to Friday. The release of new films will squeeze into the film arrangement space of old films. Unless the schedule environment has certain particularity, it is possible that after the film is postponed, there is still no good film to compete, and the postponed film itself is very high-quality. It is possible to achieve an ideal film arrangement effect, but the probability of this happening is not great. "

It can be seen from all aspects that the extension of the key has no direct impact on the film’s arrangement and box office. Usually, the news of the extension of the key released by the film side is often a statement picture, which is often ignored by many viewers, which also leads to the limited effect of the extension on many films. How to make better use of key extension and maximize its value?

Wu Yanyu mentioned: "In the second and third months, the film should reach the audience who are particularly sinking, and stimulate those who don’t walk into the cinema every day, but are willing to support domestic films if they see something they like. This is a long-term proposition, which may be particularly applicable to films that choose a key extension."

As a means, key extension is only icing on the cake after all. To win the audience and box office, the most important thing is the quality of the film itself. Whether it can stimulate the audience, stimulate their empathy and make the audience feel that it is the right thing to go into the cinema to support the film, which is the root of the film becoming an explosion. It takes hard work to strike while the iron is hot. May the creators polish their works and win by quality.

　　From January to July this year, 12,565 cases of infectious diseases were detected by the national customs entry quarantine, up by 8.62% year-on-year. Zika virus disease and Chikungunya fever were detected for the first time, and cholera, Zika and other major infectious diseases were detected many times. However, traditional infectious diseases such as plague, cholera and yellow fever break out from time to time all over the world, and new infectious diseases such as Ebola hemorrhagic fever, Middle East respiratory syndrome and Zika virus disease are constantly emerging, which may become "black swan" and "grey rhinoceros" in the field of infectious diseases at any time, bringing severe challenges to global public health and China Customs.

　　"At present, the global public health situation is very complicated and severe. The accelerated development of global trade, the more convenient transportation network and the more frequent personnel exchanges make there is only one flight distance between any new disease and the transmission area. " Zhang Jiwen, deputy director of the General Administration of Customs, said at the scene of an emergency drill for public health emergencies at ports recently held in Chongqing.

　　The reporter of "Legal Daily" learned from the General Administration of Customs that from January to July this year, 12,565 cases of infectious diseases were detected by the national customs entry quarantine, an increase of 8.62% year-on-year. Zika virus disease and Chikungunya fever were detected for the first time, and major infectious diseases such as cholera and Zika were detected many times. However, traditional infectious diseases such as plague, cholera and yellow fever break out from time to time all over the world, and new infectious diseases such as Ebola hemorrhagic fever, Middle East respiratory syndrome and Zika virus disease are constantly emerging, which may become "black swan" and "grey rhinoceros" in the field of infectious diseases at any time, bringing severe challenges to global public health and China Customs.

The epidemic situation is unprecedentedly grim.

　　In the development of human history, the struggle against infectious diseases is an eternal main line.

　　Infectious diseases, such as smallpox, plague and cholera, have spread widely all over the world, causing hundreds of millions of casualties, which has seriously disrupted social order and affected social and economic development.

　　According to Adrian Xu, director of the Department of Health and Quarantine of the General Administration of Customs, in the 21st century, the impact of various infectious diseases has not decreased with the growth of the world economy and the improvement of people’s living standards, but with the improvement of the world transportation facilities, the epidemic situation of infectious diseases has spread rapidly around the world. In recent years, the global epidemic situation of infectious diseases has broken out one after another, with one or two new and recurrent infectious diseases appearing every year. The outbreak frequency is getting denser and denser, the scope is getting wider and wider, the harm degree is getting deeper and deeper, and the import risk is getting bigger and bigger, which makes the global public health situation unprecedented.

　　In 2014, the Ebola outbreak broke out in three African countries, causing fear and travel restrictions that almost paralyzed the whole world.

　　In 2015, a business traveler infected with Middle East Respiratory Syndrome virus returned to South Korea, quickly infecting 186 people, killing 38 people and isolating 17,000 people, which led to the disorder of health system and society in South Korea. South Korea’s exports fell by 10.9% year-on-year, and the president was forced to cancel his visit to the United States. The epidemic also spread to China.

　　In 2016, after 60 years of silence in Africa and Asia, Zika virus disease suddenly became popular in Brazil and continued to spread across borders. Because Zika virus can cause neonatal microcephaly, the World Health Organization declared it a public health emergency of international concern.

　　In July this year, the World Health Organization (WHO) announced that the epidemic situation of Ebola hemorrhagic fever in Congo (DRC) has constituted a public health emergency of international concern, and the risk of epidemic spread has intensified, and the pressure of prevention and control has increased.

　　Adrian Xu told reporters that in the first half of this year, the monitoring information of the global infectious disease information monitoring network involved 68 infectious diseases and 140 countries and regions. From the range of occurrence, except influenza, measles, dengue fever, chikungunya fever, cholera and malaria are widely prevalent; According to the degree of harm, pneumonic plague, Ebola hemorrhagic fever, Middle East respiratory syndrome, Lassa fever and Hantavirus lung syndrome are the most common causes of death. In terms of epidemic areas, Ebola hemorrhagic fever, plague, cholera, yellow fever, Lassa fever and rift valley fever are mainly prevalent in Africa, cholera, Middle East respiratory syndrome and dengue fever are mainly prevalent in Asia, and dengue fever and measles are mainly prevalent in America and Europe.

Tens of thousands of infectious diseases were detected.

　　Various infectious diseases not only pose a great threat to people’s health and safety, but also have a great impact on social stability and national economy. With the continuous deepening of China’s "Belt and Road" construction and opening up, as well as the accelerated development of global trade, the more convenient transportation network and the more frequent personnel exchanges, human beings have formed a "community of destiny" in the face of epidemic diseases as never before.

　　To this end, the national customs has built a port quarantine defense line to prevent the introduction of major epidemics. From January to July this year, 12565 cases of infectious diseases were detected by the national customs entry quarantine.

　　On June 10th, the customs staff of Ningbo Airport found that many passengers on a flight from Bangkok had vomiting, diarrhea, abdominal pain and other symptoms. Customs officers immediately carried out on-site investigation and disposal, and found that 15 passengers belonging to the same tour group had symptoms of digestive tract infection. After collecting blood and other samples, the staff issued a convenient card for seeing a doctor and told them to see a doctor as soon as possible before releasing it. On June 14th, Ningbo Health Center reported that three passengers were positive for enterohemolytic Escherichia coli O157:H7. The customs immediately informed the passengers of the test results by telephone, and suggested that they go to the hospital for further review and diagnosis and treatment, and reported the disposal situation to the Ningbo Municipal Government and informed the Ningbo Municipal Health and Health Commission. At the same time, strengthen cooperation with tourism management departments, issue early warnings to travel agencies in a timely manner, and ask the recent travel team to Thailand to pay attention to the relevant epidemic situation and make adjustments to travel routes.

　　On July 1st, Kunming Customs found a China male passenger with high body temperature among the people who entered Myanmar at Changshui Airport. On-site staff immediately re-measured the passenger’s body temperature, conducted epidemiological investigation and medical investigation. After investigation, the passenger’s axillary temperature was 37.7℃, accompanied by headache, muscle and joint pain and other symptoms. The staff initially judged that they might be infected with mosquito-borne infectious diseases, so they collected blood samples for inspection at the first time. On July 2, Yunnan Health Center detected that the passenger was positive for Zika virus nucleic acid. The customs immediately informed the patients by telephone, gave them health education and informed the Yunnan Provincial Center for Disease Control and Prevention.

　　On July 11th, a flight from Kenya declared to Guangzhou Baiyun Airport Customs that a female passenger from the Democratic Republic of Congo had fever, vomiting and diarrhea during the flight. Customs officers determined that it was a suspicious case of Ebola hemorrhagic fever. The customs will start the joint prevention and control mechanism and emergency plan at the first time, and take protective and disinfection measures; Isolate the passenger, contact the local medical institution to transfer him to another hospital, deliver the sample overnight and start the 24-hour inspection mechanism. The next day, the Health and Quarantine Laboratory (P3) of the Technology Center reported that the suspected Ebola virus disease was excluded.

Prevent and resolve health risks

　　"Preventing and resolving major risks is one of the three tough battles established by the 19th National Congress of the Communist Party of China. Specific to the customs health and quarantine work, it is necessary to adhere to the bottom line thinking of preventing major epidemics and strictly controlling the security of the country, and resolutely prevent and resolve the hidden dangers of public health and safety risks at ports." Lin Wei, director of the Health and Quarantine Department of the General Administration of Customs, said.

　　In April 2018, in accordance with the unified arrangements for the reform of the party and state institutions, the duties and teams of entry-exit inspection and quarantine management were assigned to the General Administration of Customs. After the institutional reform, the customs has more supervision responsibilities, wider supervision scope and longer supervision chain, and the pressure and challenge of maintaining national security is greater than at any time in history, which puts forward new and higher requirements for customs health and quarantine work.

　　In order to prevent the introduction of major epidemic diseases and build a strong port quarantine defense line, the customs health quarantine explored the mode of "moving the border forward", sent elite soldiers and strong generals to carry out epidemic prevention and control abroad, and constantly improved the overseas infectious disease monitoring system. Strict port quarantine inspection, so that every doubt must be investigated and every policeman must be dealt with, improve laboratory testing ability, implement precision quarantine projects, carry out cross-border joint monitoring of vector organisms at key ports, implement port food safety and health supervision and sampling plan, and constantly improve the port health quarantine prevention and control system.

　　In order to improve the international travel health service for key groups such as expatriate laborers, the Customs has continuously improved the international travel health service system. In recent years, major epidemics such as Ebola hemorrhagic fever, Middle East respiratory syndrome and Zika virus disease have been properly handled, and the country has been kept. The first case of rhabdovirus infection in China and the second case in the world were detected, and six new viruses, such as yellow fever virus, Zika virus, Rift Valley fever virus, Cooper fever virus and Middle East respiratory syndrome coronavirus, which were not seen in China, were detected, achieving both "absolute quantity" and "gold content" of epidemic detection.

　　In order to strengthen supervision, optimize services and actively serve the overall situation of development. The Customs has optimized the examination and approval process for special articles, and the settlement rate reached 95% in 5 days. Implement risk management, strengthen supervision after the event, reduce the burden on enterprises, and support biomedical research and industrial development. Port health permit "two certificates in one", cancel the health permit for storage sites at border ports, and realize the online operation of 13 health and quarantine government services; Excellent completion of G20 summit, APEC meeting, Shanghai Cooperation Summit, Beijing Summit of Forum on China-Africa Cooperation, the first China International Import Expo(CIIE) and other major activities.

"Hao Car Attacks" original new car:On August 1st, 2024, FAW added a brand-new model of "Cute Horse" with an official guide price of only 24,900 yuan. The new car is not only a brand-new entry-level model of Pentium Pony, but also a new low starting price of new energy vehicles, even from the perspective of cost performance, which can be regarded as a replacement product of "scooter for the elderly". At the same time, according to the official disclosure, you can still enjoy multiple luxuries when buying a car, including exemption from purchase tax, financial discount on 1000 yuan, giving away compulsory insurance, and renewing the car at a guaranteed price, etc. In addition, there are four lifelong rights and interests worth 6,000 yuan (vehicle lifetime warranty/three-power lifetime warranty/lifetime road rescue and lifetime renewal fund). So what are the highlights of the new car?

Pentium Pony is not only the first model named by numbers in Pentium brand, but also quite different from family-style design styles such as T90 or B70 of Pentium. The rounded headlights are matched with the contrasting body, creating a "kawaii" feeling. At the same time, in order to capture the personalized needs of consumers, the new car also launched a Pentium Pony Gamer Edition or even a convertible version based on the retro style of spliced Ding Mao, including the details of the roof trunk, the integrated spoiler tail and the racing seat. Customized, and the high-profile models are also equipped with LED light sources. In addition, the new car is divided into six body colors to choose from, except Jasmine White. The cost of the selection is 388 yuan (bubble blue/camellia green/peach powder) and 888 yuan (indigo blue/cheese white), which Hao Ge thinks is not expensive.

In terms of interior, the Pentium pony can be described as simple but not simple. Although the price is less than 25,000, it has all the basic functions such as suspended instrument, air conditioning control area, radio and integrated cruise control. The key layout similar to the game console handle style is also particularly fashionable and personalized. It is worth mentioning that the newly added entry-level version of "Cute Horse" is still equipped with common configurations such as air conditioning, airbags, main driver’s cosmetic mirror, ramp assistance and the proportion of rear seats. Compared with the second-lowest cute horse, the only thing missing is the remote control of car Bluetooth and mobile APP, which is why it can be cheaper by 2,000 yuan.

In terms of body size, the length, width and height of the new car are 3000/1510/1630mm, and the wheelbase is 1953mm, which is the same as that of MINI EV (length, width, height and wheelbase are 3064/1493/1629/2010mm, respectively). As a miniature electric vehicle, space performance is naturally not a strong point, but the support ratio of rear seats can still further meet the emergency needs. After all, more convenient parking and narrow road driving ability are the biggest selling points of Pentium pony.

In terms of power, the new car offers two kinds of battery life, 122 km and 170 km. After adding the "cute horse", it happens to have two configurations to choose from. The maximum power of motors is 20 kW (27 HP); 85 nm. The battery is Ferrous lithium phosphate, which only supports slow charging. The 122km version is fully charged in about 5.2 hours, and the 170km version is fully charged in about 6.5 hours. The slow charging port is located at the front logo, with a glass water filling port beside it, and the gear shifting mechanism is knob type.

Summary of "Hao Car Attacks":As we all know, the main competitors of Pentium Pony will be locked into micro electric vehicles such as Wuling Hongguang MINI EV and Geely Panda. Compared with 300,000 ~ 400,000 "luxury" new energy sources in the market, micro-electric vehicles such as Pentium Pony seem to be a clean stream, and at the same time, it is doomed that the most important thing for its audience is high cost performance. The starting price of 24,900 yuan should be the cheapest pure electric vehicle on the market at present, so who would you choose? Thank you for your attention to "Hao Car Attacks".
