Cervical cancer is one of the common malignant tumors that seriously threaten women’s health all over the world. At present, the prevention and control of cervical cancer in China is facing the problem of low coverage of screening population, especially in areas with low health resources, and it is difficult to achieve early detection and early treatment of cervical cancer with weak primary screening technology. How to improve the level of cervical cancer screening in areas with low health resources? What role can digital technology play? Distinguished professor Qiao Youlin, School of Medicine and Public Health, Peking Union Medical College, accepted an interview with a reporter from CCTV.

Cervical cancer is different from other cancers. It has a state of precancerous lesions, which can last for 10 years or more. Qiao Youlin said that if the precancerous lesion state is found through high-precision screening, it is simple and cheap to treat at this time, and good treatment results can be obtained.

With the progress of science and technology, the time of cervical cancer screening is gradually advanced. Initially, there were no cytologists and high-tech HPV detection technologies in areas with low health resources. At that time, our obstetrician put acetic acid on the cervix, and if there was any lesion, there would be a white lesion, which was called acetic acid white staining test. Later, it was improved to cytological examination, and whether cytology has changed with a microscope made the diagnosis more accurate. Further development, to use molecular biology methods to check the nucleic acid of the virus. In this way, it can be detected when the virus has just been infected without causing cytopathy. Qiao Youlin said that it is precisely because the World Health Organization has seen that cervical cancer has a vaccine and that screening technology has improved that we can eliminate cervical cancer. .

Each country has its own regulations for defining the age of cervical cancer screening. Generally, the age of government-led screening in our country is defined as 35 to 64 years old. Qiao Youlin said that if ordinary people want to go to the hospital for examination by themselves, they can have a cytological examination at the age of 25. If it is HPV testing, you can do it at the age of 30.

The World Health Organization proposes that cervical cancer should be eliminated globally, and adult women aged 35 -64 should be screened regularly. At present, there are two plans in China: one is to check once every three years and use cytological methods to detect; One is to check once every five years, using HPV detection technology. Qiao Youlin said that adult women between the ages of 35 and 64, if they check every three years, need to check 10 times in their lifetime; If you check it every five years, you only need six checks in your life. In 2019, the state decided to include the "two cancers" screening of cervical cancer and breast cancer in the scope of basic public health services. Qiao Youlin said that it is difficult to implement the policy in areas with low health resources. One is the lack of financial resources, and the other is that the improvement of health service capacity is not so fast. To eliminate cervical cancer in areas with low health resources, it is necessary to find a simpler, easier to operate and more efficient detection technology.

At present, HPV detection technology is being promoted in areas with low health resources. This technology is based on machine detection, which only needs sampling, and the machine produces the results, so it is not necessary to rely on doctors to look for a needle in a haystack under a microscope. Qiao Youlin said that he hopes to train the staff of maternal and child health hospitals in areas with low health resources in three years and teach the grassroots to master this technology, so that the screening of cervical cancer can be continuously promoted.

At present, the most difficult thing in cervical cancer screening is colposcopy biopsy, which is the bottleneck of secondary prevention of cervical cancer, that is, early diagnosis and treatment. Qiao Youlin said that our team is developing an artificial intelligence-based colposcopy biopsy assistant tool with the Health Pratt & Whitney Laboratory of Tencent’s Sustainable Social Value Division. It can be clear where to biopsy, and obtaining accurate biopsy point information will make doctors more confident. Qiao Youlin has been working in the front line of disease prevention and treatment, especially cancer prevention and treatment for a long time. He said that he deeply felt the great changes brought by digital technology, such as the simplest physical examination. You need to know who you are looking for and whether this person meets the conditions for physical examination. Intelligent management of the crowd and dynamic management according to individual’s specific health status make the prevention of diseases more refined and the health service more refined, and the cost-effectiveness is also cost-effective.

　　Xinhua News Agency, Beijing, August 13th Comprehensive Xinhua News Agency reporters reported that Darchiyev, director of the North American Department of the Russian Foreign Ministry, said in an exclusive interview with the Tass news agency on August 13th that the United States is increasingly becoming a direct party to the situation in Ukraine. Podolyak, adviser to the Office of the President of Ukraine, said in an interview a few days ago that there is no dialogue between Ukraine and Russia in the military and political fields.

　　— — Darchiyev said on the 13th that the United States is increasingly becoming a direct party to the Ukrainian situation. However, the U.S. military assistance to Ukraine has not had a significant impact on Russia’s special military action, and the goal of the action will be achieved. He said that Russia does not want to have conflicts with the United States or NATO. Russian troops are systematically destroying Western weapons exported to Ukraine, but the supply of long-range weapons to Ukraine by the West will lead to the expansion of the territory of special military operations. Russia will not allow weapons that pose a direct threat to Russia and Russian-controlled areas on Ukrainian territory.

　　— — Darchiyev also said on the same day that the US Congress discussed the possibility of declaring Russia a "state supporting terrorism". If the United States does this, it will cause an irreparable situation, which will cause the most serious damage to the diplomatic relations between the two countries and will lead to the demotion or even the breaking of diplomatic relations between the two countries.

　　— — Podolyak said in an interview with the media a few days ago that the current dialogue between Ukraine and Russia is limited to the exchange of prisoners of war and other humanitarian aspects, and there is no dialogue between the two sides in the military and political fields.

　　— — According to the website of the Russian Ministry of Foreign Affairs, Russian Foreign Ministry spokesman Zacharova commented on the UN Security Council’s consideration of the safety of Ukrainian nuclear facilities on the 11th, saying that the IAEA’s inspection of the Zaborozh nuclear power plant has never taken place, and the responsibility lies with the West. The west is sparing no effort to destroy and prevent the IAEA from visiting the nuclear power plant, because "the west does not need to know the truth about the Zaporoze nuclear power plant and where the nuclear security threat of the facility comes from". Since March this year, the Zaporoze nuclear power plant in southern Ukraine has been controlled by the Russian army. The facility was attacked a few days ago, and Russia and Ukraine accused each other of launching an attack.

　　— — Russian Defense Ministry spokesman Konashenkov reported on the 13th that Russian troops, Donetsk armed forces and Lugansk armed forces completely controlled the Peschi residential area near Donetsk. Russian troops destroyed the launching device of Haima multi-barrel rocket launcher and its supporting ammunition depot in Kramatorsk region. The Russian Air Force shot down four Ukrainian UAVs in nikolayev and Kharkov, and intercepted four "Haima" multi-barrel rockets in Hellson.

　　— — The General Staff of the Ukrainian Armed Forces said on social media on the 13th that the Ukrainian army repelled the Russian attack in the direction of Zaporoge and forced it to retreat. On the same day, Sergey Gedeh, the military chief executive of Lugansk region, said that on the 12th, the Russian army tried to launch an attack in Lisichansk oil refinery and other places, and at the same time, it pushed in the direction of Bakhmut from the Pasner side, and the Ukrainian army foiled the Russian offensive. Ukrainian Defense Minister Reznikov said on social media on the 12th that a new batch of M270 multi-barrel rocket launcher systems aided by Britain has arrived in Ukraine.

　　— — The Ministry of Infrastructure of Ukraine said on social media on the 12th that the fifth batch of grain-transporting fleet left the Ukrainian port on the same day, including two cargo ships, carrying a total of 63,000 tons of agricultural products.

　　Mid Autumn Festival to eat moon cakes

　　What’s your favorite flavor?

　　the data shows that …

　　Hangzhou fresh meat mustard tuber moon cake, Huizhou dried plum moon cake, etc.

　　Traditional mooncakes with special features are still popular.

　　There are also many innovative mooncakes worth tasting.

　　What flavor of moon cakes do you prefer?

　　Look at the data together

　　↓↓↓

　　As a traditional food for Mid-Autumn Festival, moon cakes attract many consumers to buy. With the continuous improvement of consumption level, people’s demand for moon cakes has also changed, which has promoted the innovation of merchants and enriched the moon cake market from the aspects of taste and gift box packaging.

　　This year’s Mid-Autumn Festival, "multi-flavor moon cakes" ushered in a consumption boom. The data shows that over 30% of consumers strongly appeal for "finding moon cakes in combination and tasting moon cakes with different brands and tastes at one time", and over 70% of consumers hope that the Mid-Autumn Festival gift box will include more than three kinds of moon cakes with different tastes and brands. In addition, 40% of consumers are concerned about healthy low-sugar moon cakes. This reflects that consumers’ consumption demand for moon cakes is only increasing, and it also indicates that there is still great potential for the development of moon cake industry in the future. Merchants need to seize holiday hotspots, cater to consumers’ needs, strengthen the supply of moon cakes with different flavors, and strictly control the quality of products.

　　In terms of taste choice, traditional taste is still the most popular among consumers, and 74.5% of consumers prefer traditional taste. Among them, egg yolk lotus seed cake and Wuren moon cake are more favored by consumers. The endless stream of innovative moon cakes satisfies consumers’ diversified taste bud experience. Moon cakes with tea flavor such as green tea and coffee, low-sugar and low-fat moon cakes such as buckwheat and miscellaneous grains, and novel moon cakes such as snail powder and kung pao chicken are loved by consumers. Consumers are also very willing to try early, and traditional moon cakes with local characteristics such as Hangzhou fresh meat mustard tuber moon cake, Huizhou prune moon cake, Yunnan buckwheat moon cake and Wenzhou pier moon cake are very popular.

　　Generally speaking, if the moon cake market wants to keep hot, businesses need to innovate and develop constantly, and combine traditional and modern flavors to meet consumers’ demand for multi-flavor moon cakes. At the same time, we should also pay attention to product quality and brand image building, enhance cultural connotation, and strive to stand out among many brands.

1905 movie network news There is no doubt about the status of screen kung fu.

It has been more than 30 years since Donnie Yen, a martial artist, appeared in more than 70 action movies, which have already left the "Zhen Shi style" fighting firmly in the hearts of the audience.

From May 16th, the movie channel will broadcast a Donnie Yen’s screen classic at different stages at 20:00 every night for a week, and let’s see how Zhen Kung Fu is tempered!

01　Reach the peak during the martial arts period

"I have been filming for 37 years and made 78 films, most of which are martial arts films. Many viewers have never seen them, which is to let everyone know me." In 2019, Donnie Yen summed up his artistic career in an interview with 1905 Film Network.

In 2008, a film "Ip Man" asked Donnie Yen to bring this legendary figure to the public.

The master image created by Donnie Yen in the four films of "IP Man" series, which combines elegant gentlemanly demeanor, profound moral cultivation and superb martial arts, has made the box office go up all the way, set off a new wave of kung fu movies, and kept the popularity of the legendary IP in this decade unabated.

On May 18-20, the film channel will broadcast three films in the series "Ip Man" and "Ip Man 2: The Legend of the Master".

Ip Man series posters

Donnie Yen had been playing on the screen for 24 years before Ip Man appeared in 2008.

Facing the unfamiliar Wing Chun Boxing, Donnie Yen, who has been practicing martial arts since childhood, spent nine months studying Wing Chun’s boxing methods and routines.

IP Man

Since then, he has spent a lot of time training Wing Chun Boxing, and also brought a wooden stake with the crew, and practiced hard in the hotel during the filming interval. The son of Ip Man praised his training results greatly.

Fist fighting, round table fighting, boxing ring fighting … …

Ip Man 2

Under the guidance of martial arts, Ip Man is fierce and swift on the screen, and the fighting with "Zhen Shi style" is enjoyable.

Donnie Yen also put the same effort into literary drama.

In order to play the emaciated state of living IP Man who had no food to eat during the Anti-Japanese War, Donnie Yen deliberately lost weight. Even when not shooting, I wear robes to find the status of the characters.

IP Man

The director of Ip Man said: "Ip Man should not show the dazzling kung fu, but its spiritual core."

Why are fighters?

Donnie Yen’s interpretation of both civil and military disciplines vividly shows Ip Man’s national integrity, and he and his role have achieved each other, eventually becoming an irreplaceable kung fu superstar on the screen.

02　"actual combat style" boxing to meat

"I’ve been looking for some popular directions in the world in action movies. As a martial artist or making a movie, I keep thinking, what is the outside world like now?"

At 8 o’clock on the evening of May 16th, in "Special Identity", which will be broadcast by the movie channel, Donnie Yen has already introduced the actual combat style into the action film, and integrated MMA mixed martial arts and Brazilian Jiu Jitsu into it.

Special identity

Epinephrine raging peak confrontation between justice and sin, there is no gesture, but a real fight that makes people’s heart beat faster.

Special identity

This innovation brought new life to action movies, and also made him nominated for the best action design in the 33rd Hong Kong Film Awards.

03　I don’t just want to be a kung fu star

"In the first 20 years, I spoke completely with my fist."

However, he once said that he not only wanted to be a kung fu star, but also gained recognition in martial arts instruction and improved his acting skills.

In the movie "Martial Arts" broadcast at 8 o’clock on the evening of May 17th, Donnie Yen put away that vicious spirit. In this "new martial arts" movie, he portrayed his image as a master who was vaguely in the city, and with a cool attitude towards life, he forbeared to tell the truth that "ordinary is bliss".

In The Journey to the West, which was broadcast on the evening of May 21st, Donnie Yen used makeup for up to four hours every day to hide his true self. the Monkey King, who he played, had a vigorous posture and thick hair, and was wild and hard to hide his ignorance, showing his "Zhen Kung Fu" under a stick.

In the comedy action movie premiered on the evening of May 22nd, Donnie Yen subverted the cool and handsome image in the past and challenged the comedy role through more exaggerated special effects makeup.

A second ago, he was an energetic and awesome police officer. The next second, he was transformed into a fat man weighing 220 Jin.

Fat dragon crossing the river

Today, the 58-year-old Donnie Yen is still exploring ways to broaden the play.

In Donnie Yen’s autobiography "Ask Dan Xin", he described his growth process in the most plain language: "In fact, knife wounds, bumps and bruises are only’ broken materials’, and the old bones and muscles I have accumulated for practicing martial arts and making movies for many years are the pains that enter the bone marrow and keep me awake all night."

The 40-year life as a fighter has brought Donnie Yen’s martial arts attainments to the peak, and at the same time, his passionate interpretation of many roles has made him think more when filming.

It is his every "fist effort" that shows us the "Zhen Kung Fu" of both civil and military training!

A few days ago, we learned from the official channels of Dongfeng Nissan that the new classic went on the market and continued to launch two models, the comfort version and the luxury version. The official guide prices were 108,600 yuan and 118,600 yuan respectively. The main differences were that there were more luxury versions, single sunroof, leather seats, 8-inch central control screen, multi-function control of steering wheel, rear center armrest, front fog lights and remote control of mobile phone App.

Sylphy Classic is actually the previous generation Sylphy, and it is currently sold in the same room as the 14th generation Sylphy, so as to meet the needs of consumers with different budgets. In addition, due to the serious involution in the automobile market at present, the Sylphy family has a big discount in the market. Take Sylphy Classic as an example, the landing price of the comfortable version is only 80,000 yuan, although the configuration is not rich, even the central control screen is not available, but these are not big problems and can be solved by adding it later.

At the landing price of more than 80,000 yuan, you can buy such a well-known joint venture car, and it is also an automatic transmission, which still has great appeal for many pragmatic consumers with limited budgets.

For a family car, there may be no rich configuration, but it must be economical and worry-free. Sylphy Classic is equipped with a 1.6L naturally aspirated engine and matched with CVT gearbox. This power combination undoubtedly meets household needs well. According to a fuel consumption App query, it can be known that the fuel consumption of Xuanyi Classic Comfort Edition comprehensive road conditions is 6.92L/100km, and the minimum fuel consumption is 5.98L/100km, which is relatively fuel-efficient.

Although CVT gearbox can’t drive fiercely, it is more acceptable to consumers than dual-clutch gearbox. Sylphy Classic’s power combination has been tested by the market and performed well in stability. In addition, thanks to the large amount of possession, it is also very cheap to maintain at ordinary times. Just find an auto repair shop on the roadside and you can get it for two or three hundred yuan.

The 14th generation Sylphy focuses on the market with a slightly higher positioning, and competes with Volkswagen/,Toyota/and other models. It is under this strategy of high and low positioning and new and old sales under the same roof that Sylphy can rank among the top three in the sales list of compact cars every month.

It is undeniable that with the general trend of new energy, fuel vehicles have been robbed of a lot of market share. However, for consumers in third-and fourth-tier cities and small counties, their annual mileage is not much, and choosing a plug-in hybrid or pure electric vehicle can’t save much car cost, so these consumers are still more inclined to choose fuel vehicles.

In addition, unlike first-and second-tier cities, most consumers in third-and fourth-tier cities and small counties have a budget of about 100,000 yuan when buying a car. Such new energy vehicles with optional prices are relatively limited, and they have to worry about the subsequent stability of the vehicle. Therefore, the low-profile Sylphy is more in line with their car scenes.

Finally, if you have a budget of about 100,000 yuan, would you like to choose Sylphy or a new energy vehicle?

　　　 1905 movie network exclusive feature This new film, which was released on May 27th, was directed by tim burton, who has always taken a brain-hole route. In this film, he only worked as a producer. The director was replaced by James Bobin, who didn’t have many film works, and the most famous one was with the American TV series flight of the conchords … So, can you rest assured that he made a sequel to Alice?

36% freshness of rotten tomatoes

　　　 Even if all the original actors return, they can’t stop the terrible fate of word of mouth. The freshness of rotten tomatoes is 36%, and the Metacritic is as low as 37 points. Variety, Hollywood Report and Guardian all give only 40 points. Foreign media generally believe that special effects can’t save the story. This is a sequel to the dog’s tail with Burton’s name.

　　　 In fact, looking at this year’s North American summer file, there is not only such a sequel in Hollywood, but also Divergent 3, Team USA 3, Alice 2,,,, … … These films are also produced by six Hollywood studios respectively. This summer’s summer stalls are full of money, so let Zishijun help you count them:

Disney’s money-circling darts

　　　 Disney has always poked the audience with fairy tales, adventures, Marvel Comics and Star Wars home runs. In this summer file, it started to change, followed by the real-life fairy tale Alice in Wonderland 2, and finally the adventure story appeared. Previously, as an adventure sequel, the trump card has always been a series starring Johnny Depp. Depp has been playing a neurotic man since the beginning of this series, and this madness has made the crazy hat in the series all the way.

Alice in Wonderland 2

　　　 The global box office of Alice in Wonderland 1, created by Tim Burton, has exceeded one billion dollars, and Disney’s fairy tale adaptation of live-action movies seems to have changed from a sideline to a mainstay. From Alice in Wonderland 1, Disney fairy tale movies, although new bottles of old wine have been put along the way, the dark wind of this fairy tale is still loved by female audiences and young audiences. However, it is precisely because of tim burton’s distinctive personal style that this series is at best a knockoff without him, and word-of-mouth is normal.

　　　 In contrast, Finding Nemo 2 brought by Pixar and Disney is worth looking forward to. In 2006, Disney bought Pixar Animation Studio for $7.4 billion. After this acquisition, Pixar founder john lasseter became the leader of Disney. After the acquisition of Pixar, Disney Animation also won the Oscar for Best Animated Feature Film for the first time. Pixar is more like Disney’s warranty, and this sequel is led by Pixar veteran andrew stanton. The story is also a sea adventure that Dolly started to find herself.

Captain America: Civil War

　　　 In addition, on the last day of 2009, Disney bought Marvel Comics at a price of $4 billion. Since then, it has owned more than 5,000 Marvel comic character resources such as Spider-Man, Iron Man and X-Men, and in the following years, it has brought dazzling superhero movies, with a global box office as high as $1.5 billion and successfully attracted RMB 1.4 billion after being released in the mainland.

　　　 The series released by Disney has increased from 69.345 million yuan to 1.171 billion yuan in five years. This box office growth is due to the success of The Avengers and the movie universe carefully planned by Marvel and Disney. Good stories, big patterns, big scenes, and overwhelming action scenes all made these sequels stable at the box office, and Disney really dug up a gold mine.

　　　 According to the financial report released by Disney in 2015, Disney’s total revenue exceeded $50 billion last year, and its share price rose by 30% over the same period. Surprisingly, the revenue of the film business only accounted for $7.3 billion. This reminds me that the career map of this entertainment empire has already spread all over movies, games, toy derivatives, and theme parks, almost the entire industrial chain. And these sequel to the movie’s performances are undoubtedly consolidating the value created by each image.

　　The runaway black hole escapes from its host galaxy (art picture).

　　Image source: NASA/European Space Agency

　　Science and Technology Daily, Beijing, April 11th (Reporter Liu Xia) According to a report by the American Fun Science Network on the 10th, American astronomers have discovered a "runaway" black hole, which seems to be escaping from its host galaxy and running wildly in space, dragging some gases and stars behind it. The research team pointed out that if this discovery is confirmed, it will be the first observational evidence that supermassive black holes can be ejected from their host galaxies and roam in interstellar space. Related research was published in the latest issue of Astrophysics Journal Express.

　　When the researchers used the Hubble Space Telescope to observe the dwarf galaxy RCP 28 about 7.5 billion light-years away from the Earth, they found this "runaway" black hole, which showed a bright stripe. Subsequent observations show that this stripe is more than 200,000 light years long, about twice the width of the Milky Way, and is composed of compressed gas that forms stars. The stripes point right at the center of the galaxy, which is usually the "site" of supermassive black holes.

　　The research team estimates that the black hole is about 20 million times the mass of the sun and is leaving its host galaxy at a speed of 5.6 million km/h.

　　Peter Van Dokum, a professor of physics and astronomy at Yale University, the main author of the study, pointed out that they found a thin line pointing to the center of the galaxy in the image of the Hubble Space Telescope, and then they used the Keck Telescope in Hawaii to find that this line is connected with the galaxy. Detailed analysis shows that a huge black hole is being ejected from the galaxy, dragging gas and newly formed stars on the "tail". If this inference is confirmed, it will be the first time that scientists have clear evidence that supermassive black holes can escape from galaxies.

　　Dokum explained that when three objects with similar mass interact with each other because of gravity, the two objects will "join hands" and the third object will "eject". This may mean that this "out of control" black hole was once part of a pair of rare supermassive black holes. During the merger of galaxies, the third supermassive black hole "intruded" and "expelled" one of them.

　　Dokum said that the ejection of supermassive black holes from galaxies has been predicted for 50 years, but so far scientists have not clearly observed such phenomena. They also need to use other telescopes to further observe and find direct evidence of this black hole.

CCTV News:From December 23, 2021, Xi ‘an began to implement the city’s closed management. How to treat the role of closed management in Xi ‘an? What is the focus of community prevention and control at this stage? On January 1st, the reporter from the reception desk interviewed Zhang Canyou, a community prevention and control expert of Shaanxi Working Group of the State Council Joint Prevention and Control Mechanism, who was participating in the first-line community prevention and control in Xi ‘an, Shaanxi.

Zhang Canyou, an expert in community prevention and control of Shaanxi Working Group of the State Council Joint Prevention and Control Mechanism, and an associate researcher of China CDC:Because the incubation period of COVID-19 (virus) is 1-mdash; In 14 days, there is a process from exposure to infection to onset. Closed management can reduce the social mobility, and combined with nucleic acid screening can effectively realize the early detection of positive infected people and reduce the social risk to a relatively low level.

At present, Shaanxi Working Group of the State Council Joint Prevention and Control Mechanism has sent 30 community prevention and control teams to all districts and counties to help local communities find problems, so that all community prevention and control measures can be truly implemented, refined and implemented, and further reduce the spread risk of society.

Zhang Canyou, an expert in community prevention and control of Shaanxi Working Group of the State Council Joint Prevention and Control Mechanism, and an associate researcher of China CDC:With the extension of closed management, the community level is facing more and more pressure to ensure supply, which requires Xi ‘an to co-ordinate resources and manpower of all parties, do its best to provide materials for residents’ lives, and ensure the demand for medical treatment, so that residents can stay at home with peace of mind. From the perspective of nucleic acid, it is necessary to do a good job in nucleic acid screening in key areas, that is, areas where patients are relatively concentrated, which can increase the frequency of screening accordingly. In addition, it is more important to strictly implement various measures at the community level, so as to further reduce the risks at the community level.

At present, in some areas of Xi ‘an, the control measures for some sub-secret workers are home isolation.

Zhang Canyou, an expert in community prevention and control of Shaanxi Working Group of the State Council Joint Prevention and Control Mechanism, and an associate researcher of China CDC:Xi ‘an’s decision to isolate the sub-secret connection at home is based on the actual situation. For people who are isolated at home, they need professional guidance from medical staff, such as how to do personal protection at home, how to ventilate the room, and how to deal with daily domestic garbage, all of which need professional guidance. For areas with relatively concentrated positive infections and high risks, the sub-close contact suggestion here is to carry out transshipment and centralized isolation observation.

For the next adjustment of prevention and control measures, Zhang Canyou gave his views.

Zhang Canyou, an expert in community prevention and control of Shaanxi Working Group of the State Council Joint Prevention and Control Mechanism, and an associate researcher of China CDC:Now after several rounds of nucleic acid screening, we have seen some positive changes. We can also see that there are no cases in some surrounding counties, such as Gaoling District and Lantian County. When adjusting, we can give priority to making some adjustments from these surrounding counties without cases, and also consider combining other principles, such as adjusting our prevention and control measures step by step from suburban counties to core counties, from communities without cases to communities with cases.
