Tell everyone a "cold" news, the strongest cold wave since the winter of this year is coming soon! It is predicted that from November 26th to 30th, the cold wave will sweep across China, and the temperature will plummet in most areas.

　　Speaking of the cold wave, many people have memories dominated by it. As the "strongest" cold air, how "cold" is the cold wave? What is the strongest cold wave in history? The reporter interviewed Ye Dianxiu, a senior engineer under research at the National Climate Center and the chief expert of meteorological services at the China Meteorological Bureau, and asked him once and for all.

　　1. What is the standard of cold wave? Is there a difference between the north and the south of China?

　　Cold wave is a kind of cold air and a kind of disastrous weather. According to the national standard of cold air grade in China (GB/T 20484-2017) formulated in 2017, the cold air activity that makes the daily minimum temperature in a certain place lower than or equal to 8℃ within 24 hours, or lower than or equal to 10℃ within 48 hours, or lower than or equal to 12℃ within 72 hours is called cold wave.

　　2. How strong is the "ability" of cold wave cooling?

　　Monitoring shows that the average cooling rate of each cold wave in most parts of China is above 10℃. The average cold wave cooling rate in most parts of Northeast China, Jianghuai, eastern Jianghan, Jiangnan and southern China, as well as most parts of Inner Mongolia and northern Xinjiang can reach 12.℃To 14℃, more than 14℃ in most areas of Guangdong and Guangxi.

　　The maximum cooling range of cold waves in Northeast China, most of North China, most of Northwest China, most of Huanghuai, most of Jianghuai, southern Jiangnan and most of Inner Mongolia and Tibet is above 20℃. Among them, the maximum cooling rate in most parts of Northeast China and Inner Mongolia, northern Xinjiang, northwestern Tibet and southwestern Qinghai can reach 25.℃To 30℃, more than 30℃ in some areas; The maximum cooling range of cold wave in Sichuan basin, most of Yunnan and Hainan is below 15℃, and that in other parts of the country is generally below 15℃℃To 20℃.

　　3. How many cold waves occur on average every year in China?

　　In China, cold waves mostly occur in late autumn, winter and early spring. In the past 30 years (1991-2020), cold waves have occurred 5.4 times a year on average in China.

　　Since 1991, the most frequent cold wave occurred in 2021, with 11 times. Followed by 2009, there were 8 times, and the least number of cold waves was in 2017, only 2 times.

　　4. Where did the cold wave affect our country come from?

　　The cold air affecting China can be roughly divided into the following four paths:

　　① Northwest route: Cold air enters China from the White Sea and Barents Sea west of Xindi Island via Siberia and Mongolia in the west.

　　② Northern route: Cold air enters northern Asia from Kara Sea or Novosibirsk Sea east of Xindi Island, and enters China from north to south via Mongolia.

　　③ Western route: Cold air affects eastern China from west to east in Eurasia south of 50 degrees north latitude via Xinjiang.

　　④ Northeast route: Cold air from the Sea of Okhotsk or eastern Siberia affects the northeast of China.

　　more thanPath,The first three paths are more common, while the last path is less frequent and less intense.

　　5. What are the cold waves with large temperature drop in history?

　　According to the monitoring results of cold air process, since 1991, the top five cold waves with comprehensive cold air intensity in China have appeared on November 4-9, 2021, March 11-14, 2006, March 18-22, 1998, February 14-17, 2020 and April 11-17, 2006.

　　Cold waves often bring a wide range of severe cooling, strong winds and snowfall. Taking the cold wave process from November 4 to 9, 2021 as an example, the land area with the temperature drop exceeding 8℃ is 7.709 million square kilometers, accounting for about 80.3% of the national land area. Among them, there are 1.011 million square kilometers whose temperature drop exceeds 16℃.

　　The daily minimum temperature of 172 national meteorological stations in Xinjiang, Gansu, Qinghai, Ningxia, Shaanxi, Shanxi and other places reached or exceeded the historical extreme value in early November.

　　The daily precipitation of 151 national weather stations in Liaoning, Jilin, Heilongjiang, Inner Mongolia, Hebei, Tianjin, Shanxi, Shandong and other places exceeded the historical extreme in November. There is obvious snow in many places in the north, and the depth of snow in Inner Mongolia, Jilin and Liaoning is more than 40 cm.

　　6. Where is the place most favored by the cold wave in China?

　　In China, the frequency of cold wave is characterized by more in the north and less in the south. The areas most favored by cold waves include: Northeast China, western and northern parts of North China, northern and central parts of Northwest China, most of Tibet, Inner Mongolia and other places, with an average annual cold wave frequency of more than 4 times. Among them, there are generally 10 to 15 times in the eastern and northern parts of Northeast China, most of Inner Mongolia and parts of northern Xinjiang, and there are more than 15 times in some areas.

　　7. In cold winter, are there more cold waves than in warm winter?

　　The answer is no.

　　There are obvious differences in judging factors and time periods between cold winter and cold wave, and the annual cumulative cold wave frequency is not necessarily related to cold and warm winter. Cold winter is a kind of climate concept based on the temperature condition of the whole winter, and the basic element of judging cold and warm winter is the average temperature of winter (December to February) for three months. The basic factors to judge the cold wave process are the daily minimum temperature (≤4℃) and the 24-hour (or 48-hour, 72-hour) cooling range (≥8℃, 10℃ or 12℃).

　　Therefore, the number of cold waves in cold winter is not necessarily more than that in warm winter. For example, both 1998 and 2019 were strong warm winters, and the number of cold waves was 6, which was more than that of strong cold winters in 1983 (3 times), 1984 (2 times) and 1985 (2 times).

1905 movie network news Recently, a set of "Full Fire" posters were exposed in the action crime film directed by,,, and starring. The film will be released nationwide on July 6.

The movie "Anti-Drug 3: People in the End of the World" tells the story of the drug lord Kang Sucha (Liu Qingyun, played) who has been engaged in drug dealing with his subordinate Zhang Jianxing (Guo Fucheng, played). The new member Ou Zhiyuan (Gu Tianle, played) also has a life-long friendship with the two due to an accident, and the three are brothers. After Kang Sucha’s drug trafficking business in Hong Kong was investigated by the police, he fled to the Golden Triangle with his team to develop, but accidentally discovered that there were undercover agents around him. At this moment, it is enemy or friend, and it is at a loss…

The undercover clues previously revealed in the movie "Anti-Drug 3: Man in the End of the World" have triggered a large number of viewers to speculate about the identity of the three people, and the new character poster seems to amplify this mystery again. The poster released this time is set against the background of artillery fire and flying white powder collisions. The three people stand in the smoke of gunpowder and attack wildly. Below is the hot action scene integrated into the film, adding to the already shocking picture.

Gu Tianle calmly aimed and was ready to go, Liu Qingyun fiercely and arrogantly shot, and Guo Fucheng’s smile had a profound meaning, continuing the charm of the characters presented in the previous materials. The positive and negative identities of the three were still difficult to distinguish in the smoke of gunpowder, and the characters full of suspense and tension and the hard-core style of the film at a glance made people look forward to experiencing a hot anti-drug war on the big screen.

It is reported that although two or two of the three powerful actors have collaborated on film and television works before, in the movie "Anti-Drug 3: Man in the End of the World", the three of them are on the same stage for the first time, which makes people wonder what kind of sparks will collide. Guo Fucheng said: "It is fate to have this opportunity for us to cooperate. We all go all out and hope to make a very good work, a good work for everyone to enjoy."

1905 movie network news Scheduled to be released nationwide on the first day of the new year 2019, director Stephen Chow’s "New King of Comedy" has now opened for national pre-sale. On January 22, the film held a "self-cultivation of actors" conference in Beijing. Director Chow Xingchi and 10 leading actors appeared together. The creators all wore orange ribbons on their wrists, which meant to recommend this "sincere (orange) work" to the national audience.

The scene exposed many film details, not only revealing the inside story of the "Dragon Set Troupe" for the first time, but also sharing the bitterness and laughter behind the transition from "Dragon Set Life" to "New Comedy King Life". Xing Ye bluntly said that it was their enthusiasm that moved him; Zhou Xingchi and Wang Baoqiang made an update on the scene to test the actors’ "self-cultivation". Faced with the question of "fried cold rice" on the Internet, Zhou Xingchi responded humorously on the spot: "I have fried Yangzhou fried rice, but I have never fried cold rice". Wang Baoqiang also responded modestly to the question of "selling stupid", admitting that "I will turn the doubt into a motivation for hard work".

There were many surprises at the press conference, and Zhou Xingchi’s early audition clips were broadcast. The line of "looking for a princess" that Xingye said that year was a hint that he was looking for "Snow White" Wang Baoqiang 30 or 40 years ago; Wang Baoqiang, as a "super star fan", sent Xingye a cartoon of his mental journey in the 20 years after watching "King of Comedy", in order to thank the director for his encouragement. "Liu Piao Piao Piao" Cecilia Cheung even sent refueling blessings to "Yin Tianchou" from space, ridiculing him that "he said that he would only raise me, but now he has raised so many people", and inspiring everyone to continue to work hard for their dreams!

　

The "Dragon Troupe" revealed the inside story of the casting selection, and E Jingwen was named the "most beaten" heroine

Since the official announcement, there has been a lot of curiosity about "The King of New Comedy", among which the most concerning is Xing Ye’s choice of actors. At this press conference, the lead actor made his first full lineup appearance, and the story behind the casting selection was exposed. The female lead, E Jingwen, played Rumeng, an elderly young woman who was a walk-on. She said that she had similar experiences both in and out of the play. She joked that she was selected by Xing Ye because she "carried the beating". It was revealed that she was determined to "hold on no matter what" before entering the group. Who knew that Rumeng was often bullied and beaten during the walk-on in the film, and the longest was even "beaten for two days in a row". She joked: "The beating has broadened the scene", which can be called the "most beating" female lead.

In the film, Zhang Quandan plays Rumeng’s boyfriend Charlie, who claims that he has the temperament of a "gentle trap", and that "extra gentle and special trap is mysterious" is even more appetizing to the audience.

Jing Ruyang, who plays Rumeng’s best friend Xiaomi, bluntly said that his legs were shaking when he first saw Xing Ye.

One of the screenwriters of the film, Huang Xiaopeng, was also selected by the director to play an important role. In the play, he silently guarded the dream, which can be said to be a double guarantee for the screenwriter. Cai Zerui, who played the director of the play, said that he was selected by the director because he was a "literary youth".

And Miao Yilun, who plays a well-known director, spoiled the scene with "forever is from now until the destruction of the universe, you will not succeed" and hit Rumeng hard, and apologized at the scene "I regret it", encouraging everyone "Don’t listen to what the self-righteous people say, dreams and the future must be fought back with your own hands".

When it was the turn of Zhou Yunshu, who played Wang Baoqiang’s assistant, to introduce her, she showed off her "repeater" characteristics on the spot, and touted Wang Baoqiang in the audience, showing professionalism and adding bursts of laughter to the warm scene.

Compared with the newcomers, veteran actors Zhang Qi and Yuan Xingzhe play the heroine’s parents in the film. The two praised the experience of working with Chow Xingchi: "He really wants everyone to be the best." "Working with Xingye has a kind of spiritual oxygenation." The relationship between the heroine Rumeng and her parents in the film is very touching, and the actor Zhang Qi also said: "I hope parents in the world can understand their children."

"I was very touched," Mr. Chow said of the real reasons for choosing the actors. "When I was filming, I could feel their enthusiasm. When I saw them after so long, I saw that they were still as enthusiastic, and I was very touched." He said: "Each of us is Yin Tianchou, and we are all working hard for our dreams, and I am also working hard for my dreams." He also hopes that "The King of New Comedy" will give more strength to the hard-working people in the new year, "I hope the audience will be more confident and work harder after watching the movie."

　

Zhou Xingchi’s early audition clips were exposed, and the live funny comments considered themselves "the best actor"

At the scene, Zhou Xingchi and Wang Baoqiang reacted to the other starring stars’ exam questions. In the burst of laughter, the starring stars explained what "actor’s self-cultivation" is. Demonstrate how to use the correct posture to watch "The King of New Comedy" on the first day of the new year; and in the test of the exam question "Meet Zhou Xingchi, he chooses you as the protagonist", Xing Ye personally played the role, and the starring stars restored the real joy and excitement when they were selected by Xing Ye at that time.

After starring in the "audition", Chow Xingchi’s precious audition footage from his early years was also broadcast live. In the video, the young Andy Lau and Tony Leung’s audition clips were also displayed together, instantly triggering a wave of "memory killing". Xing Ye watched the performance of the three people with a smile. When the host asked who was the best actor, he replied with a smile: "Me." Then he solemnly expressed his enthusiasm for acting from his former self and friends, and found that he still had a fire on his body. Speaking of the line of "looking for a princess" back then, Xing Ye laughed that this should be a hint that he was looking for Wang Baoqiang, so he searched for 30 or 40 years before finally finding Wang Baoqiang who played "Snow White".

"The New King of Comedy" is a movie full of "little people". In the Spring Festival when big stars and big productions gather, many people break a cold sweat for it. In this regard, Zhou Xingchi bluntly stated that the result is not important, what is important is to convey emotion and temperature: "My purpose is always to make the audience like it, and I hope that in this work, the audience can find themselves and find hope."

　

Zhou Xingchi Wang Baoqiang confronted the outside world and questioned "Liu Piaopiao" and blessed "Yin Tianchou" in the air.　

Since the official announcement, not all expectations have accompanied "The New King of Comedy", and some people have expressed doubts. At the press conference, Zhou Xingchi and Wang Baoqiang responded to two sharp doubts and faced them head-on. Facing Zhou Xingchi’s question of "what else can you do besides fried cold rice", Wang Baoqiang said: "Your guesses about Xingye’s movies are sometimes inaccurate, and you need to feel it yourself." Zhou Xingchi responded humorously: "I have fried Yangzhou fried rice, but I really have never fried cold rice."

Regarding Wang Baoqiang’s question of "what else can you do besides being stupid", Lord Xing smiled and said, "In fact, I also really want to know what else he can do, so I found Baoqiang, but I didn’t expect him to be able to play Snow White." Wang Baoqiang expressed his gratitude to netizens: "Thank you all for motivating me in various ways, which has strengthened my determination to continue to work hard."

The scene also prepared a special surprise for Xingye on the same day – Cecilia Cheung, who played "Liu Piao Piao Piao" in "King of Comedy" 20 years ago, sent blessings to "Yin Tianchou" through the VCR, and ridiculed him "back then that he said he would only raise me, but now he raises so many people". This scene of air dialogue caused bursts of exclamations on the scene.

As a "super star fan", Wang Baoqiang sent his carefully prepared paintings on the spot, restoring his 20-year journey of being deeply influenced and inspired by "King of Comedy", in order to thank "King of Comedy" Zhou Xingchi for his encouragement, "20 years ago," King of Comedy "inspired me, and 20 years later, this" King of New Comedy "will definitely inspire more people. I believe that after watching the movie, everyone will feel that Star Lord’s comedy has always made you laugh and cry, and will be inspired and deeply moved." 20 years ago, the time and space connection, the strong human touch touched the warm audience.

The film "The King of New Comedy" is directed by Stephen Chow, and co-starred by Wang Baoqiang, E Jingwen, Jing Ruyang, Zhang Quandan, Zhang Qi, Yuan Xingzhe, Huang Xiaopeng, Cai Zerui and Miao Yilun. The film is currently on pre-sale across the country. It will be released on the first day of the new year to cheer up the hard-working self and harvest positive energy in the new year!

"Thank you for your concern and support for Huaxizi all the time. I’m sorry we’re late. I have a few heartfelt words to tell you."

On the evening of September 19th, the official Weibo of Hua Xizi, a domestic make-up brand, released a letter to the public, which positively responded to the recent controversy for the first time.

Hua Xizi said in the letter, "I am very sorry for taking up too many public resources. Appreciate everyone’s urging,We have fully recorded the relevant opinions, and the team is also comparing, revising and upgrading them one by one, adhering to the initial heart.To bring you better products and services. In the future, we will continue to share with you what the brand is doing, so that everyone can understand Hua Xizi in more forms. Down-to-earth, steady and far-reaching; Let a hundred flowers blossom and domestic products become stronger. "

From the official Weibo of "Hua Xizi"

Recently, the domestic make-up brand "Hua Xizi", which was pushed to the forefront by Li Jiaqi’s remarks, was picked out by many netizens. Compared with other domestic brands, the price per gram of its products is high, such as the price per gram of eyebrow pencil is comparable to that of gold, and the price per gram of loose powder exceeds that of Chanel, an international brand. The company was once caught in the whirlpool of public opinion because of its "high price".

On September 10th, when Li Jiaqi, the network anchor, introduced a Huaxizi eyebrow pencil in 79 yuan, he saw a netizen leave a message saying that it was getting more and more expensive. He asked, "Where is it expensive? It’s been this price for so many years. Don’t talk nonsense with your eyes open. Domestic brands are very difficult … "Later, Li Jiaqi said:" Sometimes I find my own reasons. After so many years, my salary has not risen. Have you worked hard? " Since then, many topics around the high price of Huaxizi’s products, such as "Huaxizi’s response to the expensive eyebrow pencil", "Huaxizi’s exclusive monetary unit for migrant workers", "How expensive Huaxizi is" and "Huaxizi’s eyebrow pencil can buy two grams of gold for more than 980 grams", have been on hot search for many days.

For a long time, Hua Xizi has positioned herself and aimed to become a high-end makeup brand. Hua Mantian, the founder of Hua Xizi, also admitted that the unit price of Double Eleven Hua Xizi was pulled from 100 yuan to 200 yuan in 2021. "For a long time, the middle and high-end market of China cosmetics has been monopolized by international brands. But today, many products of Huaxizi have cut into the middle and high-end price belt and achieved certain success. "

"This large-scale attention and discussion is a valuable opportunity for us to listen to the real voices of different consumers, and it is also the starting point for the team to self-examine and start again." Hua Xizi said in the letter this time, "I sincerely apologize to everyone. In the past week, Hua Xizi has received great attention from the whole network. We are sincere and at a loss, and the brand has not spoken before. During this time, we have continuously absorbed your criticisms, opinions and suggestions. "

At the same time, Hua Xizi also refuted the previous rumors about "Japanese brands" in the letter. Hua Xizi said that the company was founded in Hangzhou, and its R&D center, production factory and tax payment are all in China. It is an out-and-out China brand. "As a young China makeup brand, Hua Xizi hopes to tell the story of China and inherit the beauty of the East."

Previously, in response to this rumor, Hua Xizi responded to the The Paper reporter that in 2019, Hua Xizi cooperated with a Japanese research institute for short-term production, research and production. With the continuous improvement of the comprehensive strength of domestic beauty research and development and industrial chain, all cooperation with the institute and related factories was stopped in 2020. At present, 100% of Hua Xizi’s research and development centers and production factories are in China.

Zhejiang Yige Enterprise Management Group Co., Ltd. (hereinafter referred to as Yige Group), the parent company of Huaxizi brand, was founded in Hangzhou in 2014. It is a China beauty group integrating independent research and development, brand building, product sales and customer service. According to official website of Yige Group, in 2016, the domestic make-up brand "Hua Xizi Florasis" came into being.

In addition to the hot discussion and doubts caused by the high price, some netizens have reported in the past that when the average commission rate in the industry is 20%, Hua Xizi raises the proportion with a wave of his hand, and some anchors can even get 60% to 80% commission. At that time, related topics such as "more than 20% of Huaxizi’s revenue comes from Li Jiaqi" and "Huaxizi responds to Li Jiaqi’s high commission" were also listed on the hot search.

On the evening of September 11th, Hua Xizi responded to the The Paper reporter that the information on the Internet about Hua Xizi’s rebate to Li Jiaqi was as high as 60% to 80%, or even more than 100%, which was false rumor, and the proportion of cooperation rebate between Hua Xizi and Li Jiaqi was the industry average.

Photographers are creating around the long street banquet.

　　At noon, the rain stopped, and after the traditional sacrifice and blessing activities, the New Year’s dinner was officially opened in the sound of firecrackers for 20 minutes. 260 tables filled with dishes and thousands of tourists crowded the 1,132-meter-long old street.

Laughter, cheers, shouts of punching and drinking … turned the ancient town upside down.

　　In yesterday’s old street, visitors with bowls and chopsticks could be seen everywhere. They shuttled between the tables, with a piece of pig’s head meat on this table and a piece of fish on that table. Yan Han, a photographer who rushed from the main city, simply put a pair of chopsticks in his camera bag, and when he met his favorite dish, he took out his chopsticks and took a bite. The residents of the old street are extremely hospitable. Whenever anyone passes by, they will warmly greet them: "Come, look at what you eat." They also invite guests to sit down, drink wine and chat at home. Diao Shukun, a 77-year-old resident of the ancient town, specially asked someone to write a couplet and stick it on the door, with the first couplet saying that "tea is not cold when people walk" and the second couplet saying that "the host and guest are always hot" and the second couplet saying "fragrant tea is good for water".

　　WHO official: There will be a secondary infection in COVID-19.

　　The intensity and duration of human immune response have not yet been determined.

　　Recently, many places reported cases of secondary infection in rehabilitation patients in COVID-19. On 26th local time, Kokhov, technical director of WHO’s health emergency project, said that both asymptomatic infected patients and severe patients will have immune response after being infected with Covid-19, but the intensity and duration are not fully understood.

　　It pointed out that, based on the research experience of other human coronaviruses, it is indeed possible to infect Covid-19 for the second time, and there may be other undiscovered cases of secondary infection, but it does not necessarily happen frequently.

　　Kokhov stressed that the existing tools can avoid infecting Covid-19, such as keeping your body at a distance and wearing a mask. Even if you have been infected with Covid-19, you should still take these measures. This is a new normal life and will continue for some time.

　　Outbreaks occurred in colleges and universities in at least 24 States after the start of school in the United States.

　　Cdc downplays the importance of virus detection, which leads to dissatisfaction.

　　In the United States, where the epidemic is the most serious, the cumulative number of confirmed cases has exceeded 5.82 million and the number of deaths has reached nearly 180,000. At present, many universities in the United States have started school, and the spread of the epidemic on campus is not optimistic.

　　As of the 25th local time, since students returned to school, colleges and universities in at least 24 states in the United States have reported relevant cases, and the cumulative number of confirmed cases of college students and faculty has exceeded 3,300, which has brought no small challenge to the resumption of classes and epidemic prevention and control in the United States.

　　Among them, the University of Alabama has reported more than 500 confirmed cases of COVID-19 since 19th, and school officials said that the growth rate of confirmed cases in the university has reached an "unacceptable level".

　　In addition, the University of Southern California said that just after the first week of school in autumn, there was an "amazing increase" in the number of infected people in our school. Since the 10th, 90 students and 10 faculty members have been infected with Covid-19. Only one week after the opening of Iowa State University, 130 people tested positive for the virus. Texas A&M University also reported more than 400 confirmed cases.

　　With the outbreak in many universities in the United States, many universities have been forced to resume online teaching. However, when the epidemic situation is so severe, the US Centers for Disease Control and Prevention (CDC) revised its COVID-19 guidelines on 26th local time, and the revised guidelines played down the importance of Covid-19 testing for people without symptoms.

　　In this regard, New York Governor Cuomo said that "the latest guidelines of CDC are essentially self-contradictory, which is completely contrary to what he said before". He also said that "updating the guidelines is for political purposes" and that New York State will not follow the latest guidelines. New York State Health Commissioner Zach also revealed, "I have talked with CDC scientists, and they said that this change is related to politics."
