Third, safeguard measures

(A) improve the working mechanism

Local communication administrations should establish a collaborative promotion mechanism for the construction of "broadband frontier" with local departments such as industry and informatization, education, ethnic work, finance, natural resources, transportation, agriculture and rural areas, health and health, energy, border management, forestry and grassland, railways, etc., formulate work plans, clarify the division of tasks, and submit the work plan to the Ministry of Industry and Information Technology before the end of March 2024. Establish a task ledger, communicate and coordinate regularly, promote the solution of network construction and maintenance difficulties, and report the work progress, existing difficulties and problems to the local party Committee and government on an annual basis.

(2) Guarantee capital investment

Basic telecommunications enterprises should focus on improving the development level of broadband networks in border areas, ensure the investment of network construction and operation and maintenance funds in border areas, actively urge local companies to undertake construction tasks, and exclude the costs involved in undertaking the construction tasks of telecom universal service projects when assessing the operating efficiency of companies in various provinces, cities and counties. China Tower Co., Ltd. should actively undertake the task of building the tower site in frontier areas, and increase its support for the telecom universal service project in accordance with the requirements of relevant documents. The Ministry of Industry and Information Technology and the Ministry of Finance make overall consideration of the demand for "broadband frontier" construction, and give key support to the demand for network coverage in rural areas with high construction cost and poor natural conditions in the telecommunications universal service project.

(3) Improve support policies

Encourage relevant local departments to introduce special policies, strengthen the connection between network infrastructure and municipal and public service infrastructure in border areas, and reserve construction space in advance; Strengthen the power supply guarantee, do a good job in effectively connecting the access computer room, mobile communication base station and other planning with the power facility planning, and simplify the approval process. Local natural resources, forestry, grassland and border management departments should actively coordinate and solve the problems of land use, forest use, grass use and sea use involved in the construction of communication optical cables, submarine cables and base stations, and speed up the relevant procedures. Encourage local governments to actively coordinate the reduction and exemption of compensation, sea area use and other related expenses. The State Council State-owned Assets Supervision and Administration Commission (SASAC) eliminated the relevant impacts in the performance appraisal of enterprises undertaking the task of "broadband frontier construction". Fully endowing the construction of "broadband frontier" with the significance of highlighting the consciousness of the Chinese nation’s community, and the State Ethnic Affairs Commission gives support in carrying out relevant appraisal and commendation.

(4) Deepening cooperation and sharing

Encourage all localities to promote the facilities of government agencies and institutions to open to the construction of "broadband frontier" free of charge. Strengthen cross-industry resource sharing, and promote the two-way sharing of resources such as pipe holes, towers/watchtowers, station sites and computer rooms between basic telecommunications enterprises and municipal, transportation, electric power, forestry and grass industries. Encourage relevant industry units to open power towers, traffic signal poles, road portal frames, video surveillance poles, highway pipe holes, railway channels and other resources to build communication facilities in a reasonable and fair market-oriented way on the premise of meeting the use requirements in this field and meeting the requirements of norms and standards, safe production, friendly consultation and clear responsibilities. Strengthen co-construction and sharing within the industry, promote cross-enterprise stock resources mutual cooperation, and enhance network robustness.

(E) to strengthen the tracking efficiency.

Relying on the national telecom universal service management support platform, strengthen the monitoring and evaluation of network infrastructure construction and key indicators of network quality in border areas. Basic telecommunications enterprises should strengthen the tracking and analysis of network construction investment, network scale and business development in border counties, and local communication administrations should carry out daily supervision and spot checks on the implementation of key tasks, and regularly report the progress to the Ministry of Industry and Information Technology to ensure that all tasks and objectives are completed on schedule. Organize the summary and evaluation of the construction of "broadband frontier counties" and set up a number of typical models with distinctive characteristics and remarkable results.

(6) Intensify publicity.

The Ministry of Industry and Information Technology, together with relevant departments, will strengthen the analysis of the progress and effectiveness of the construction of "broadband frontier" and increase publicity and promotion. Support relevant media organizations to flexibly adopt various forms, dig deep and actively publicize typical cases and experiences in the construction and application of "broadband frontier". Local communication administrations, basic telecommunications enterprises and China Tower Co., Ltd. should strengthen the combing of typical cases in their own regions and enterprises, carry out experience exchange and sharing, and create a good construction environment.

Not afraid of the United States warning North Korea to go its own way and declare that it will solemnly commemorate the Army Day.

CCTV News:No.3 Labor News, the organ newspaper of the Central Committee of the Workers’ Party of Korea, published an article saying that North Korea will solemnly commemorate the Army Day this year.

The article said that February 8 this year marks the 70th anniversary of the founding of the Korean People’s Army. The Political Bureau of the Central Committee of the Workers’ Party of Korea made a decision last month to set February 8 as the Army Day of the Korean People’s Army, and said that relevant commemorative activities will be held every year.

The article said that celebrating the Army Day is the unanimous idea of the Korean military and civilians, and no one has the right to comment on it. It has become a common practice and common sense that no matter which country in the world attaches importance to the founding day of its own army and will hold relevant commemorative activities grandly.

The article said that it was unreasonable for some Korean media and conservatives to make irresponsible remarks about the commemoration of the Korean Army Day.

According to Korean Central News Agency’s previous report, the Political Bureau of the Central Committee of the Workers’ Party of Korea issued a decision on January 22nd to designate February 8th as the Army Day of the Korean People’s Army. The report said that February 8, 1948 was the day when the birth of the Korean People’s Army was announced. The Political Bureau of the Central Committee of the Workers’ Party of Korea made the above decision to carry forward the revolutionary achievements of Kim Il Sung, the founder and builder of the Korean People’s Army.

North Korea suddenly changed the Army Day to Pyeongchang Winter Olympics. Senior US official: No military parade

On January 31st, US Deputy Secretary of State Steven goldstein said that the United States hoped that North Korea would not hold a military parade on February 8th, the day before the opening of the PyeongChang Winter Olympics. He also said that any American citizen who goes to this Winter Olympics can rest assured that South Korea has deployed a comprehensive security system, and the US government is giving support to South Korea in this regard.

An official of the the State Council Diplomatic Security Bureau said that about 100 US security personnel will be deployed at the US Embassy in South Korea and the Winter Olympics. American officials also said that they have not noticed any special threats at present and believe that South Korea has the ability to ensure the safety of the Winter Olympics. The 23rd Winter Olympic Games will be held in Pyeongchang, South Korea from February 9 to 25. North Korea previously announced that February 8 will be designated as the Army Day of the Korean People’s Army.

40 years later, the Korean Army Day was changed back to February 8.

North Korea announced on January 23rd that the Political Bureau of the Central Committee, the Workers’ Party of Korea, decided to set February 8th every year as the founding day of the Korean People’s Army, that is, the Army Day, and set April 25th as the founding day of the Korean People’s Revolutionary Army, the predecessor of the People’s Army. This is North Korea’s rescheduling of the Army Day to February 8 after a lapse of 40 years.

The Korean Central News Agency reported that the Political Bureau of the Central Committee, the Workers’ Party of Korea, issued a decision on the 22nd, saying that the two anniversaries were set up "to carry forward the revolutionary achievements of Comrade Kim Il Sung, the founder and builder of the Korean People’s Army".

The late Korean president Kim Il Sung formed an anti-Japanese guerrilla on April 25th, 1932, and later developed into the Korean People’s Revolutionary Army. According to the decision, this is the first revolutionary armed force formed by Kim Il Sung. On February 8, 1948, Kim Il Sung formed the Korean People’s Army with thousands of cadres and soldiers who participated in the armed struggle against Japan and passed the test of revolutionary struggle as the backbone. It is the direct successor of the Korean People’s Revolutionary Army. The decision stated that Kim Il Sung strengthened and developed the Korean People’s Revolutionary Army into a regular revolutionary armed force and announced the birth of the Korean People’s Army.

The decision requires that party organizations at all levels in North Korea invest in political and ideological education and various activities on February 8 every year, and the cabinet and other relevant departments take concrete measures to commemorate the Army Day.

Net exposure Sogou browser security vulnerability sogou response is unclear

On November 5th, a message about "Sogou browser was exposed with obvious loopholes and tens of millions of users’ privacy was leaked in batches" began to spread to major media from the Kafan Forum.

According to the news, after logging in to Sogou browser with qq account, users will be able to find thousands of user names, accounts and passwords of unfamiliar users on many websites. There are inexplicably a lot of web pages in the user’s browser favorites that the user has not stored before. After opening the corresponding favorite web pages, even the browser will automatically fill in the user name and password and conduct electronic transactions directly.

For the first time, browser security vulnerabilities leaked privacy incidents, and sogou urgently needed to give users an explanation.

Some related technicians found files such as "HistoryUrl3_base" and "FormData3.dat" in the local browser of Sogou browser, which could not obtain the corresponding information without using professional software. After the Sogou browser synchronized the user’s stored account password and the webpage in the favorites to the cloud, the synchronized data was synchronized to other users’ computers, resulting in the disclosure of a large number of users’ private data information, which will lead to a large number of users’ property losses in this vulnerability incident.

It is understood that the recent Sogou browser security breach leaked user privacy security incidents for the first time in history, and a large number of user privacy data leaked and distributed incidents caused by browser security breaches. As a historical precedent, the security vulnerability incident of Sogou browser will attract more users’ attention. sogou needs to speed up the process of fixing product vulnerabilities and give users an early account of this matter.

New sogou made a good start. The biggest impact of Sogou browser security incident was sogou search

Since the news that sogou will be acquired by 360 on May 10th this year, it has been more than four months since the news that "Tencent acquired 36.5% shares in sogou" was confirmed, and the acquisition of sogou came to an end temporarily.

On November 3rd, sogou released the unaudited financial report for the third quarter of sogou as of September 30th, 2013. According to the report, the total revenue of New sogou in the first quarter of 2013 (the first quarter after sogou was acquired by Tencent with a 36.5% stake) was US$ 57 million, up 53% year-on-year, which set a good start for the development of New sogou.

And CNZZ, a traffic statistics agency, shows in the report that sogou search occupied 12.06% of the whole domestic search market on October 26th, reaching a new high.

After the browser is the most important Internet portal, Sogou browser, as the first event that a large number of user data are leaked due to browser security vulnerabilities, will not only have a great impact on its own development. As another sogou search business that can get more data from users and is more qualified to be an Internet portal, it will probably change the rapid development of Tencent after its shareholding, resulting in a small-scale share reduction.

Therefore, the security incident of Sogou browser is not only related to the future development of Sogou browser, but also will affect the development of sogou search-based sogou. (According to the vulnerability test of Dagong. com reporter at 11: 40, the security vulnerability of Sogou browser is no longer there.)

Sogou denied that the rumor of browser security vulnerabilities was ugly. "The poster said that the account was stolen."

After the sogou browser security vulnerability incident was widely spread by the media, which attracted the attention of the industry and even the society, sogou announced yesterday that the technical team of sogou browser started to verify the authenticity of the incident as soon as possible after the "sogou browser security vulnerability" incident was reported online, and confirmed that there was no security vulnerability in sogou browser. As for the reasons for this kind of news, sogou said that its strong development momentum made some competitors launch unfair competition in the name of kidnapping users, and especially said that it would not give up protecting the ultimate rights and interests of users by legal means.

Subsequently, at around 20: 31 yesterday, the k53941 user who had previously posted "Sogou browser broke security holes" on the technical forum card meal also posted that the owner of this user ID had not used it for a long time, and this time, the behavior of repeatedly posting multiple Sogou browser vulnerability posts was caused by the hacker after the ID password was stolen.

In this regard, some netizens expressed doubts. Since this user did not log in to this ID number for several months, why did he log in to this account shortly after the security vulnerability of Sogou browser was exposed? Are there still some unknown things behind it? Can this user also expose the login record of his forum account to improve the credibility of his speech?

Previously, on the platform of Black Cloud Vulnerability, many people in the industry and outside the industry have personally witnessed the seriousness of privacy leakage in view of the privacy leakage of sogou Pinyin. At that time, the announcement given by sogou was that Bing, the search engine, did not abide by the agreement of robots.txt, but it did not claim that its team’s means of protecting the privacy of input method was not enough, and more secure verification methods should be used to protect the privacy of input method users. As a heavyweight product in the legendary three-stage rocket of sogou, sogou input method is a leading product in both PC and mobile Internet. After a product with such a huge number of users has privacy loopholes, this response has aroused the dissatisfaction of many sogou input method users, and also provided opportunities for other input method manufacturers to develop users.

This time, regardless of whether there is a security loophole in Sogou browser, we will not consider whether posting claiming that the account was stolen is a way for sogou to refute rumors. After sogou became a shareholder in Tencent, his performance did show a good development trend. In this security vulnerability incident, the third-party vulnerability platform Wuyun and 360 security guards clearly stated that in a certain period of time, the second vulnerability of Sogou browser did exist. No matter whether the vulnerability incident is an oolong incident or not, sogou should give users a more comprehensive and satisfactory explanation, and try not to blindly find ways to excuse themselves. Users know whether there is a vulnerability, and promise to provide users with a better Sogou browser, and promise that sogou can compensate those users who have really suffered economic losses from Sogou browser as long as relevant certification materials are given. Is it a better way to deal with the incident?

More than 600 yuan per gram, young people rushed to buy gold ornaments, and the price reached a record high.

The price of gold has gone up again. In the morning of December 4th, the global gold price hit a new record high. With the international gold price rising, domestic gold retail and jewelry prices have risen again. On December 4th, the unit price of gold jewelry per gram of several jewelry brands in Hefei exceeded that of 630 yuan, and it was slightly adjusted back on December 5th. Some salespeople said that the price of gold will remain high in the short term, and many "non-just-needed" consumers will stay on the sidelines, which will have an impact on sales.

The price of gold ornaments in the provincial capital reached a new high.

As the international gold price rises, the price of gold jewelry rises accordingly. On the morning of December 5th, in Chow Tai Fook Hall of the Top 100 Drum Tower Famous Products Center, the retail price of gold jewelry and ornaments was 619 yuan per gram, handicrafts were 609 yuan per gram, and investment in gold was 562 yuan per gram. Li Xiaorong, director of the store, told Anhui Business Daily that the price of the day had dropped from the previous day. On the 4th, the price of jewelry gold was 630 yuan, and when the 30 yuan discount per gram was included, the price also broke through 600 yuan, setting a record high. "The current highest point this year is also the highest price in these years."

In an old temple nearby, Gold, the price of all-gold 999 jewelry on that day is also 619 yuan per gram, and you can enjoy 30 yuan discount per gram. Shop assistant Zheng Hailan told Anhui Business Daily that the price of gold has been fluctuating for nearly half a month, with a fluctuation of more than ten yuan almost every day, and it has remained above 600 yuan for many days.

 Anhui Business Daily reporters learned that the prices of various brands of gold ornaments have risen, almost reaching the highest price. According to statistics, the latest price of Chow Tai Fook is 630 yuan, which is 34% higher than the lowest price in 470 yuan in recent three years and 133% higher than the lowest price in 270 yuan in recent ten years.

As the price of brand jewelry rises, so does the wholesale price. Near Hong Kong Street, Ningguo Road, Hefei, there are many gold wholesale dealers. In an old Hongfu jewelry store, manager Peng Nannan introduced that the store is a direct selling model, and the price is synchronized with Shenzhen Shuibei Gold Wholesale Market. The price of that day is 475 yuan per gram. "It fell today. It was 495 yuan the night before yesterday and 482 yuan during the day yesterday. The fluctuation was relatively large." She introduced that in my impression, the price of gold was relatively low before and after the National Day this year, and the wholesale price was about one gram of 440 yuan, and it has been rising all the way since then.

Zheng Hailan, assistant of the Old Temple Gold Store of the Top 100 Drum Tower Famous Products Center, told Anhui Business Daily that the price of gold continued to rise this year, which had an impact on "non-just-needed" consumers. The current monthly sales volume dropped by more than 10% compared with the same period last year. "Many old customers are optimistic about the style and say hello to me. The price of gold has dropped and it has not dropped." Zheng Hailan has an old customer. He got married at the beginning of last year and bought "hardware". This year, he accompanied his brother to buy it. "The same weight, a set bought, is more than 3,100 yuan more expensive."

Young people become the main consumer

Who is buying gold? Anhui Business Daily reporters visited and found that in addition to investment demand, young people have become the main force in the gold jewelry consumer market. According to the Consumer Insight Report of China Gold Jewelry Consumption Industry in 2022, from 2016 to 2021, the proportion of young people buying gold has increased from 16% to 59%, and young people are an important group of gold consumption.

Peng Nannan, the jewelry manager of Lao Hongfu, told Anhui Business Daily that in recent years, young people have bought more and more gold. "This year’s popular enamel and palace style are particularly popular."

Li Xiaorong, store director of Chow Tai Fook Club, said that in the past, young people bought more diamonds and platinum when they got married, and gold has become the mainstream in these years. "Young people are generally more pragmatic, and they will pay attention to the preservation of gold. The’ three gold’ and’ hardware’ are basically based on gold." In addition to marriage, the consumer demand for "pleasing yourself" is also growing. "Necklaces and rings under 10 grams, fashionable and exquisite products are very popular." 

In a Senfan jewelry store on Ningguo Road, Ms. Zhang, the person in charge, said that in addition to buying gold rings and necklaces, many young people played a "fixed investment in kind". Pay a salary every month to buy yourself a "golden melon seed" and "golden beans" and put them in a bottle.

The market outlook needs to pay attention to the dollar and the world situation.

What’s the next step for gold prices? Traders in the financial market department of Bank of China Anhui Branch analyzed that due to geopolitical uncertainty, the decline of the US dollar index and the expectation of the Federal Reserve’s interest rate cut, the price of gold may remain high next year.

"The price of gold in the international market is denominated in US dollars. Under the condition that other factors remain unchanged, the depreciation of the US dollar will boost the price of gold." According to analysis, the current US dollar index has been at the highest level in 20 years, and the probability of turning down in the future is high, which means that gold has a high probability of continuing to rise in the future.

"On the other hand, gold has a strong risk-aversion property. International geopolitical risks such as the Russian-Ukrainian war and the Palestinian-Israeli conflict have triggered a great increase in investors’ risk aversion and stimulated strong demand for gold in the market. The imbalance between supply and demand is likely to lead to a further rise in gold prices." According to analysis, from the perspective of the Fed’s monetary policy, the market is expected to cut interest rates by the Fed in the near future. If the US dollar enters the interest rate cut channel in the future, the US dollar exchange rate may be under pressure immediately, and the flow of funds between US dollar assets and gold may be more active.

Many salespeople in the provincial capital believe that the price of gold may remain high in the short term. Zheng Hailan, the assistant of the old temple gold shop, believes that two months before and after the Spring Festival every year is the real peak season for gold sales, and it will not be ruled out that it will rise again.

Looking forward to the May 1 ST file: "King of the Sky" will break the box office record? Who is the 1 billion+dark horse?

Wen | Zhao Erba Dao

This is the first May 1st shift since the "recovery", and it is also a long-awaited holiday.

At the same time, it is also a rather crowded film schedule, with a variety of films. Up to now, nearly 20 films have been announced to enter the May Day schedule this year (and a few have been withdrawn), and the number has exceeded the same period of previous years, including the popular King of the Sky, Countdown Love You, Nightlife in Changsha, Unfamiliar Road in Life, and Out of Fire, which are very lively and competitive.

So, in the coming May Day holiday, which film will be the winner in the market? Which one or several films have become dark horses at the box office?

Looking back on the May 1st movie market over the years, this paper analyzes the scale, rise and characteristics of May 1st movie.

For a long time, the May Day file was a relatively small file period, and it was more regarded as the transition between the Spring Festival file and the summer file.

According to the data, before the epidemic, the total box office revenue of the May 1st file accounted for a small proportion of the annual box office, which was 660 million in 2016, 780 million in 2017 and 1.01 billion in 2018. After that, the May 1st file began to break out and became a very important movie schedule:

According to the data of Lighthouse Professional Edition, in 2016, the winner of the May 1st box office was Love Letter from Beijing Meeting Seattle, the runner-up was Fantasy Forest, followed by Phantom of the Magic Palace and Dream Partner, and the final box office was 786 million, 779 million, 88.401 million and 80.986 million respectively.

In 2017, the top 51 movies were Speed and Passion 8, Shock Wave 2’s Master of Memory, Like You and Saving Zhiming with Spring Jiao, with final box office of 2.671 billion, 400 million, 292 million, 210 million and 175 million respectively.

In 2018, The Later Us, The Behind-the-scenes Player and The Furious Beast led the box office in Ready Player One, with the final box office of 1.361 billion, 358 million, 1.003 billion and 1.396 billion respectively;

By 2019, the box office income during the May 1st period was close to 2 billion yuan, among which Avengers 4, as the final work of the series, can be said to occupy most of the market share, and finally the box office reached 4.25 billion yuan, followed by Why Be Home and The Former, which reached 376 million and 138 million respectively. During the May 1st period in 2021, My Love won the championship with 512 million box office, Zhang Yimou’s Above the Cliff ranked second with 505 million, and Secret Visitor ranked third with 190 million. The box office of these three films finally reached 789 million, 1.191 billion and 214 million respectively.

Through the performance of the May 1st movie market from 2016 to 2022, we can actually see some laws:

First of all, the overall box office is on the rise, from the initial 660 million to the current scale of approaching or breaking through 2 billion;

Secondly, the single-chip box office should not be underestimated. As early as 2016, the box office champion of the May 1 ST file could get 780 million box office. After that, movies that broke the box office of 1 billion began to become common in the May 1 ST file.

Thirdly, in terms of film types, commercial blockbusters did well in May 1st, such as Reunion 4, Speed and Passion 8, Ready Player One, etc., but May 1st is also a harvest season for romantic films, and My Love’s Beijing meets Seattle and Later are all very typical romantic films with very successful box office.

In addition, dark horses are also very common during the May 1st period. More importantly, the influence of May 1st movies actually has a long tail effect. For example, Above the Cliff is a typical movie that keeps a good growth rate at the box office after holidays.

Learning from the old, I have the following expectations for the upcoming May 1st in 2023, like Reading Entertainment Jun and many friends who love movies:

1. Can the total box office return to the growth rate before the epidemic and reach or exceed 2 billion during the May Day holiday? During this period, whether 2 ~ 3 movies can break through 1 billion+at the box office is also an important concern of the May 1 ST file;

2, domestic films, single box office can break the previous schedule record? The films released during the May 1 ST period, which finally broke the box office by 2 billion, are all overseas blockbusters. Then, will this record be broken in 2023? The performance of King of the Sky is worth looking forward to;

3, will the dark horse film appear, whether the romantic film can reproduce its previous glory and so on.

Who is the most crowded May 1st stall in 2023? Who is the dark horse?

Up to now, 19 films have been announced to enter this year’s "May 1 ST" file, the number of which has exceeded the same period in previous years. The types of films involve action films, suspense films, romantic films, comedies, historical films, cartoons, etc. However, the popularity of these films in the announcement stage and the expectations of the audience have already varied widely.

Chen Jin, a data analyst of Lighthouse Professional Edition, said that this is obviously a positive signal, which makes the film have a more adequate announcement cycle. Indeed, the preheating situation of this May 1st file is quite lively, and the pre-sale figures are also very powerful.

According to the data of Lighthouse Professional Edition, as of 20: 30 on April 24, the total box office (including point screening) of the 2023 May 1st new film pre-sale exceeded 103 million. Among them, "King of the Sky" is currently riding the dust with a pre-sale box office of 68.159 million yuan, "So many years" is temporarily ranked second with a pre-sale box office of 15.03 million yuan, and the third place is "Unfamiliar Life Road", with a pre-sale box office of 11.235 million yuan.

Judging from the publicity and pre-heating, the films of May 1st can be roughly divided into three categories:

The first is a film for recording, and it is also the most popular "King of the Sky" in May 1st. In the professional edition of the Lighthouse, the King of the Sky has attracted more than 860,000 people, ranking first in the May 1 movie list. The King of the Sky is directed by Liu Xiaoshi, with Gui Guan and Liu Xiaoshi as screenwriters, starring YiBo, Hu Jun and Yu Shi, and Zhou Dongyu as special stars. The film focuses on the new era air force test pilots for the first time, revealing the story behind the birth of the most advanced fighter.

On April 23, I saw the friends circle of the relevant staff send it. The premiere of "King of the Sky" was made for 28 times, and the live effect was particularly good, not only with big scenes, but also with real feelings.

Secondly, it is the genre films that can hit 500 million box office and have clear goals, namely "So Many Years", "Countdown Love You" and "Unfamiliar Road in Life".

Among them, "So Many Years" and "Countdown Love You" are direct competitors, and it is possible that only one film has the last laugh. "So Many Years" is a love movie directed by Ji Zhuqing and starring Steven Zhang and Qian Sun. It is adapted from the novel "So Many Years" of the same name in the series of "Zhenhua Middle School" in Chang ‘an in August, and it is very popular at present. And Countdown Love You has more stars, starring Chen Feiyu, Zhou Ye, Xiaotang Zhao, Sun Tianyu, etc., but after the official announcement, it was caught in a plagiarism storm-so it is difficult to predict which of these two films will become a dark horse at the box office and maintain the high-light performance of the May 1 ST romantic film.

It’s hard to predict the box office performance of Unfamiliar Life. Tingdong Film and Xiaoxing Yi are hardly box office guarantees, but they are also nerve knives. Qiao Shan and Mary can look forward to the performance of traffic stars and traffic online celebrity, but they also have doubts. I hope this comedy can also have a good box office performance, giving the audience under great pressure a space to let go.

Third, others. The box office of Out of Fire and "Check the Storm" is expected to be difficult to be in deus ex on May 1 ST, but it is also courageous to enter this period with such positive themes to meet the market test; In addition, there are seven animated family movies released in May 1st, but from the perspective of ip influence and past performance, the most popular GG Bond has never had a box office performance of over 100 million yuan, so the outside world has not expected too much from these films.

In addition, the box office of Nightlife in Changsha, which was announced with great momentum, is also difficult to predict. From the cast to the announcement, the sound volume of this film is quite high, but when it comes to the pre-sale box office, it is only 750,000 at present-the box office trend of this city with strong colors and certain fans is worthy of attention.

Therefore, the expectations for the May 1st gear are actually very clear:

First of all, can "The King of the Sky", which has a good popularity and premiere reputation, break through 2 billion, or even sprint 3 billion box office, creating a box office record for the May 1st domestic film;

Secondly, can 3 ~ 4 films break the box office of 500 million, or even touch the threshold of 1 billion+? Whether the romance "So Many Years" and "Countdown Love You" continue the tradition of high box office of romance films, or the comedy "Unfamiliar Road in Life" is worth looking forward to;

Of course, on the basis of these expectations, the box office performance of the May Day holiday will definitely return to the level before the epidemic or even catch up; Of course, we should also have a more rational understanding of the movie market of the May 1st file. Since 2023, many young people’s first choice for holidays is to travel, which should also have a certain impact on the May 1st file, but it will also extend the popularity of the May 1st file to around mid-May, which is also one of the changes in the movie schedule in recent years.

Conclusion:

In 2023, the key to the film market is recovery and growth. The Spring Festival films Manjianghong and Wandering Earth 2 both achieved high box office, and later, Keep You Safe, Journey of Bells and Slam Dunk Master continued the popularity of the film market. However, it is undeniable that it is still very challenging for the total box office of movies to return to the level before the epidemic. The May 1 ST file is a tough battle for the China film market-as the saying goes, "tiger head, bear waist and phoenix tail". Whether the summer file can be hardened or not is worth looking forward to.

CCTV Drama Review: I gave "Casting Sword in Desperate Situation" five stars!

  CCTV News:On the occasion of the 90th anniversary of Gutian Conference, the revolutionary historical TV series "Casting Sword in Desperate Situation" jointly produced by CCTV, Huace Film and Television and Xiamen Wansheng Film and Television landed on a set of prime-time hits of CCTV. This is an unforgettable history, and in all fairness, it is a meticulous work.

  As the ancient poem goes, "When we look at the side of the ridge, the distance is different", when we choose different angles and different criticism methods to treat the same TV play, the connotation, value and significance we can see are also very different. Generally speaking, there are political, economic, moral and cultural standards for judging the value of TV works. Among them, the "ratings" standard once became an important indicator.

  Over the years, CCTV has been practicing the "ratings" standard and establishing the "ecological" standard in TV evaluation. The connotation of "ecology", from nature to humanity, is very rich. In short, it is to advocate the optimization of TV ecology, advocate the "green" and "environmental protection" of TV, and create a good humanistic and social environment, which is ultimately consistent with the goal of building an ecological and civilized society advocated by the country at present.

  By introducing the concept of "ecology" to re-examine TV, we will gain a brand-new understanding of TV. By the standard of "ecology", I give "Casting Sword in Despair" five stars.

  The first star: to show the "diversity" of TV cultural ecology.

  Protecting biodiversity and maintaining ecological balance are the core concepts of ecology. As far as the healthy development of TV ecology is concerned, it is also very important to pay attention to the wide coverage of TV drama content and theme categories, avoid certain types of "prevailing" and "homogenization", and pay attention to the richness of ecological categories. For decades, China TV plays have fully demonstrated the "diversity" development trend of TV cultural ecology. Especially since 2010, the creation of TV dramas on revolutionary history has reproduced the glorious course of China revolution and painted a magnificent film and television art scroll of China revolutionary history with unique theme advantages, grand historical perspective, lofty value guidance and magnificent aesthetic character. It is a necessary complement to the previous spring tide in Europe, America, Japan and South Korea, as well as the craze for costume, Hong Kong and Taiwan, and the craze for realistic themes. Moreover, it is also a drama about revolutionary history. The focus of this drama is the historical events during the land reform period, which fills the gap in the theme of TV dramas in this period and enriches the ecological categories of TV dramas in China.

  The second star: highlight the influence of "environment" in ecology on people.

  A very core factor in ecological research is the research environment, including the influence of natural environment and human environment on people. Casting Sword in Despair is adapted from a real historical event that began in 1928. It is a past story that was born in a real history and region. It is 90 years apart from the present time and space, and it may become a fading historical memory. The value of this film lies in the efforts made by the creators to restore various historical scenes in their artistic creation, and the "handwriting" in scene selection and production restoration is amazing. Gutian site, Woods behind Gutian site, Peitian ancient village, uninhabited village, Dingwuling, Quaoli pier, Xiaozong ancestral hall and many other landmark buildings with historical features and regional characteristics are presented on the screen one by one. Pulling the audience back to the hard revolutionary years in an instant not only restores history, but also brings it to life, which is very different from the fabrication of some current time-travel dramas.

  Moreover, the characterization, character and environment in the play have formed a special relationship, especially "restoring the texture of the times" and highlighting all kinds of "conflicts" and "growth" of the characters in the ever-changing environment. This kind of "ecological" observation has broken the facebook and conceptual characterization mode, making the characters in the play more real, lovely, full of flesh and blood and touching people’s hearts. Specifically, its special "environment" lies in "the desperate situation of guerrilla warfare for three years", its core "conflict" lies in "overcoming all kinds of non-proletarian thoughts", and its special "growth" lies in the fact that it has finally grown from "a Red Army team dominated by peasants at the beginning and with complex components" to "a red iron army with firm faith and fearlessness".

  The third star respects the "naturalness" in the ecology.

  This naturalness is highlighted in the realism of "natural carving" in characterization. Judging from the drama about revolutionary history, the TV series "Casting Sword in Desperate Situation" is very "grounded" and its characters are very real and lovely. The expression of history is not rigid, not conceptual, respecting history, respecting the weakness of human nature, and not making things up. The appeal of art comes from "truthfulness". No matter whether it is the main character or the minor character, its various real and meticulous performances have a moving power. What is the true face of a team with mixed components, mainly farmers, lax discipline, unclear beliefs and scattered sand? This is one of the highlights of this drama, and it is also a place where many comedies are highlighted (for example, because sausage forgot the gun, because pork forgot to return to the team, etc.).

  Another example is the shaping of the main characters, especially Chairman Mao, who suffered from malaria because of acclimatization. There is a voice-over in the play: "The leader who led the people of China to overthrow the old world and establish a new China was also in such an embarrassing situation, which is enough to show how hard-won our socialist country is now!" There are many aspects in the film about Zhu Mao’s Red Army’s use of soldiers as gods, but this passage has broken the way of "deifying" the leaders and really has a convincing force.

  The fourth star attaches importance to the "spiritual ecology" of the characters.

  Literature and art are the project of casting the soul. General Secretary of the Supreme Leader emphasized that patriotism should be the main theme of literary and artistic creation, and people should be guided to establish and adhere to the correct views on history, nationality, country and culture, so as to enhance their backbone and confidence in being Chinese. The influence of TV series on people’s spirit is very profound, because the visual expression of TV series can easily lead to idol effect. Looking back at the TV series "Casting Sword in Despair", if we use the "ecological" standard to measure it, it is very necessary to educate people like "Do not forget your initiative mind". The independent camp in western Fujian led by Li Huacheng forged the soul of the army in the desperate situation of "no food, no bullets, no medicine", adhered to the principle of "building the party ideologically and building the army politically" established by Gutian Conference, and made concerted efforts with Chen Tianyou and other team leaders. Cruel war scenes, firm revolutionary beliefs, and the sacrifices and growth of all the soldiers have moved countless netizens: "It is really not easy to pay such a painful price behind a few strokes in history books!" "Suddenly understand us ‘ Listen to the party’s command, win the battle, and have a good style of work ’ How did the people’s army grow up! "

  The fifth star: the ecological "integrity" of the team of editors and directors.

  The attributes of TV series are complicated, which are both works of art and cultural products. Its concrete formation has its own unique cultural and ecological environment, and it is also in a unique ecological chain. Very different from traditional works of art, it is first of all the product of "team" wisdom. It is an art science, and it must be operated scientifically as a whole. From planning, scriptwriting, filming to being on the screen, it must go through a strict production process, and it must be a harmonious and optimized combination of creative factors such as screenwriter, director, actor, camera shooting, recording, art design, music, makeup, clothing and props. The so-called "amateurs watch the excitement, experts watch the doorway". If you look at the TV series "Casting Sword in Despair" from a professional perspective, you can see its "step by step" exquisiteness.

  On the one hand, this "high-quality" ecological optimization combination is based on the improvement of the professional level of China’s TV drama creation, on the other hand, it is based on the superior combination of its own creative team. In 2016, "The Desperate Defender" triggered a ratings boom, and won many awards such as "Five One Project Award", "Flying Award" and "Golden Eagle Award". As the second part of the "Three Musts" series, Casting Sword in Despair is still under the general planning of Yuan Jingui, starring Qian Linsen, a famous screenwriter, and Zhang Tong, who won the flying prize for "Breaking Defender", and adding new blood to the strength school. Affectionate patriotism, compact plot, excellent drama production, exquisite interpretation by actors, music that makes the finishing point, and many obscure behind-the-scenes creators have restored a true history for us with their professional level and dedication.

  Literature and art can’t be slaves of the market, and they can’t get lost in the tide of market economy. A good work should put social benefits first. Excellent literary and artistic works, it is best to be successful in thought and art, and to be welcomed in the market. Literature and art should be able to help build a green humanistic ecological environment and enhance the spiritual and ecological strength of the audience. Under this standard, I give "Casting Sword in Desperate Situation" five stars. It is an unforgettable historical memory, a "picture book of revolutionary heroes", and its intrinsic value, in addition to the digital display of current ratings, can also play a supplementary role in history textbooks.

Keynote Speech by Li Qiang at the Opening Ceremony of the 2023 Annual Meeting of Boao Forum for Asia (full text)

Xinhua News Agency, Boao, Hainan, March 30th

Guided by the concept of community of human destiny
Inject more certainty into world peace and development.
-Keynote speech at the opening ceremony of the 2023 annual meeting of Boao Forum for Asia
(March 30, 2023, Boao, Hainan)
Li Qiang, Prime Minister of the State Council, People’s Republic of China (PRC)

Dear heads of government,

Dear heads of international organizations,

Dear directors of Boao Forum for Asia,

Ladies and gentlemen,

Ladies and gentlemen, friends,

I am very happy to meet you in the beautiful Hainan Island and attend the 2023 annual meeting of Boao Forum for Asia. First of all, on behalf of the China Municipal Government, I would like to extend my warm congratulations on the opening of the annual meeting! I would like to extend my sincere welcome to all the guests! Thank you for your long-term concern and support for the development of China!

The theme of this annual meeting is "An uncertain world: unity and cooperation to meet challenges, openness and tolerance to promote development", which is in line with the current situation and concerns of all parties and has strong practical significance. In today’s world, chaos is intertwined, and human society is facing unprecedented challenges. Instability, uncertainty and unpredictability have become the norm. In this great change full of uncertainty, people urgently hope to have more and stronger deterministic forces to push the world forward towards a better future.

Ten years ago, the Chairman of the Supreme Leader first put forward the important concept of a community of human destiny, and then on many international occasions, including the Boao Forum for Asia, he profoundly expounded China’s proposition of building a community of human destiny, and further put forward global development initiatives, global security initiatives and global civilization initiatives, providing a Chinese plan for global development and governance. In the past 10 years, China has promoted the building of a community of human destiny with pragmatic actions and achieved a series of significant practical results. In particular, the high-quality joint construction of the "Belt and Road" has driven the vast number of developing countries to accelerate their development and opened up new space for the world economy. At the same time, it has also made fruitful efforts in advocating political settlement of the crisis, solving international hot issues, persuading peace and promoting talks, and turning war into friendship, demonstrating the responsibility of a responsible big country. These are vivid practices of the concept of a community of human destiny. Facts have proved that the concept of a community of human destiny has become a banner that leads the trend of the times and human progress, and a source of certainty that promotes lasting peace and common prosperity in the world.

Now, Asia and the world are at the crossroads of historical evolution. We must hold high the banner of the concept of a community of human destiny, work together to build a community of Asian destiny, build an anchor of world peace and stability, a source of growth and a new highland of cooperation, inject more certainty into world peace and development, and strive to create a better future for mankind.

First, jointly protect a peaceful and stable development environment and inject more certainty into the chaotic and intertwined international situation. Peace is the premise of development. In the past few decades, Asia has achieved remarkable development achievements in the world, which cannot be separated from the overall peaceful and stable environment; In order to achieve greater development in Asia in the future, there must be no chaos and war, otherwise it will ruin its future. The Five Principles of Peaceful Coexistence and the Bandung Spirit, which were born nearly 70 years ago, are the crystallization of the wisdom of the Asian people. The "Asian way", which takes mutual respect, consensus and taking care of the comfort of all parties as important principles, provides basic follow-up for cooperation and development between countries. The more turbulent the world situation is, the more we should cherish these precious wealth and resolutely protect the hard-won peace situation. We must always adhere to good-neighborliness and friendship, support ASEAN’s central position in East Asian regional cooperation, share security and destiny, and ensure lasting peace and stability in Asia. We should implement the global security initiative, adhere to the common, comprehensive, cooperative and sustainable security concept, oppose the abuse of unilateral sanctions and "long-arm jurisdiction", oppose taking sides, group confrontation and the "new cold war", persist in resolving differences and disputes between countries by peaceful means, and jointly safeguard world peace and tranquility.

Second, work together to create a more dynamic growth center and inject more certainty into the recovery of the world economy. Asia has nearly 60% of the global population, nearly 40% of the total economic output and more than 30% of international trade, and is the "ballast stone" and "propeller" of the world economy. We should implement global development initiatives, seize the opportunity of a new round of scientific and technological revolution and industrial transformation, and create new growth poles in cooperation fields such as digital economy and green economy, so as to make Asia a "power source" for world economic recovery and development. It is necessary to further promote regional economic integration, strengthen macro-policy coordination, implement the Regional Comprehensive Economic Partnership Agreement with high quality, actively promote the China-ASEAN Free Trade Area version 3.0 negotiations, build a regional production division system with complementary advantages and win-win cooperation, and promote the formation of a more open regional market. It is necessary to build an open world economy, jointly build the "Belt and Road" with high quality, promote the liberalization and facilitation of global trade and investment, oppose trade protectionism and "decoupling and breaking the chain", ensure the stable and smooth supply chain of the global industrial chain, and inject strong momentum into the development of the world economy.

Third, jointly expand effective ways of unity and cooperation and inject more certainty into profoundly changed global governance. Today’s world is a global village, the future and destiny of all countries are closely linked, and many global problems we face need to be discussed and solved together. Last year, Asian countries successfully hosted the BRICS Leaders’ Meeting, the East Asian Cooperation Leaders’ Meeting, the G20 Leaders’ Summit and the APEC Leaders’ Informal Meeting, which played an important role in improving global governance. We must adhere to the concept of global governance, actively participate in the reform and construction of the global governance system, firmly safeguard the international system with the United Nations at the core and the international order based on international law, continuously deepen cooperation in the fields of food, energy, eco-environment, disaster prevention and mitigation, climate change and poverty reduction, jointly send out the strong voice of the times of peace and development, jointly release the positive signal of adhering to multilateralism, and promote the development of the global governance system in a more just and rational direction.

Fourth, we should jointly promote the deepening of people-to-people exchanges and inject more certainty into the integration and symbiosis of different civilizations. Not long ago, the Chairman of the Supreme Leader proposed the Global Civilization Initiative, which provided important guidance for promoting exchanges and mutual learning among civilizations and promoting the progress of human civilization. Asia is the representative of the diversity of civilizations, and different civilizations complement each other. At the same time, Asian countries are at different stages of development, most of them are still developing countries, and each country has its own unique history, culture and specific national conditions. We are willing to work with all parties to implement the global civilization initiative and strive to create a new situation of cultural exchanges, cultural integration and people’s hearts. We must adhere to mutual respect, mutual trust, openness and tolerance, respect the development path independently chosen by all countries, and oppose the "clash of civilizations" and ideological confrontation. It is necessary to carry forward the common values of all mankind, strengthen exchanges in the fields of culture, education, health, youth and media, enhance understanding and trust through sincere communication, properly handle differences and problems by seeking common ground while reserving differences, and create a model for different civilizations to blend and coexist.

Ladies and gentlemen, friends!

As the largest developing country in the world, China’s development is of world significance. While doing our best to do our own thing well, we actively conform to the trend of the times of peace, development, cooperation and win-win, and always be a builder of world peace, a contributor to global development and a defender of the international order. China has created two miracles of rapid economic development and long-term social stability, which in itself is a contribution to the world. It can be said that in an uncertain world, the certainty of China is the mainstay of maintaining world peace and development. This was the case in the past, especially in the future and the present.

From the future, the development goals and prospects of China are certain. The The 20th National Congress of the Communist Party of China(CPC) held in October last year drew a blueprint for the future development of China, and clearly pointed out that by the middle of this century, the Communist Party of China (CPC)’s central task is to unite and lead the people of all ethnic groups in the country to build a socialist modernization power in an all-round way, realize the goal of the second century, and comprehensively promote the great rejuvenation of the Chinese nation with Chinese modernization. The modernization that China wants to build is a modernization with a huge population, the common prosperity of all people, the harmony between material civilization and spiritual civilization, the harmonious coexistence between man and nature, and the peaceful development path. We will never realize modernization by means of war, colonization, plunder, etc., and will definitely make more than 1.4 billion people move into a modern society by peaceful development, which will bring strong momentum to economic growth in Asia and the world. To accomplish this central task, it takes a long period of continuous struggle. In this process, no matter what changes take place in the world, we will always adhere to the drive of reform, opening up and innovation, which will not only inject new impetus and vitality into the economic development of the whole world, but also let all countries in the world share the opportunities and dividends of China’s development. I think a long-term stable and dedicated China, a down-to-earth and courageous China, and a confident, open and sharing China must be a great force for world prosperity and stability.

At present, the momentum and situation of China’s economic growth are strong. In the first two months of this year, China’s economy showed a trend of recovery, with major economic indicators such as consumption and investment improving, employment prices generally stable, market expectations improved significantly, manufacturing purchasing managers’ index continuously stood above threshold, and several international organizations raised their expectations for China’s economic growth this year. Real scenes may be more convincing than statistics. Take Hainan Island, where Boao Forum is located, as an example, the tourism industry has changed from "Golden Week" of the Spring Festival to "Golden Month" and "Golden Season", and tourists are always everywhere, and the sales of duty-free goods on outlying islands continue to be hot, which fully reflects the strong economic resilience, great potential and vitality of China, the long-term positive fundamentals of China’s economy, and the scientific and effective policies and measures for China’s economic and social development. In the next step, we will continue to adhere to the principle of stability and strive for progress, consolidate and expand the economic recovery to a good trend, and promote the sustained overall improvement of economic operation; We will organically combine the implementation of the strategy of expanding domestic demand with deepening the structural reform on the supply side, and continue to expand the market scale of China; We will introduce new measures in expanding market access, optimizing the business environment, and ensuring the landing of projects, and constantly optimize the institutional environment in which state-owned enterprises dare to do things, private enterprises dare to venture, and foreign companies dare to invest; We will effectively prevent and resolve major risks, especially to maintain the overall stability of China’s financial operation and firmly hold the bottom line that no systemic risks will occur. We are confident and capable of pushing the great ship of China’s economy to ride the wind and waves, make steady progress and make greater contributions to the development of the world economy.

Ladies and gentlemen, friends!

Another "Asian event" this year is that the 19th Asian Games will be held in Hangzhou in the golden autumn. The epidemic delayed the meeting and made us look forward to it more. From the ends of the earth to the west lake, there are many beautiful places in the open China. You are welcome to visit more. Where there is scenery, there must be a new economy, and there will be many mutually beneficial and win-win cooperation business opportunities. I believe that as long as we join hands, unite and cooperate to meet challenges, be open and inclusive and promote development, we will certainly bring more certainty to Asia and the world, and we will certainly create a better future for human society!

Finally, I wish the Boao Forum for Asia Annual Conference 2023 a complete success!

Thank you!

It’s almost the New Year, and you can’t help but know the truth behind the reminder post in the circle of friends.

  The free charging treasure sent on the road hides the Trojan horse? Does the Exit-Entry Center of the Ministry of Public Security close the system ahead of the Spring Festival holiday? "Eating melon seeds = drinking oil", are these true? At this time of the year, some rumors related to the Chinese New Year will come out one after another. Today, I will take a look at it for you. Let’s take a look.

  The free charging treasure sent on the road hides the Trojan horse?

  Content:Recently, a video of a "free charging treasure hidden mystery" shot from a media account was spread on the Internet. After the "free charging treasure" in the video was dismantled, there was a hidden device that stole the user’s mobile phone information. Is this true?

  Truth:It is theoretically and practically possible for the modified charging treasure to steal the information of mobile phone users, which can be realized by installing a Trojan horse program. During my stay in Spring Festival travel rush, I hope everyone will take precautions at railway stations and various stations, and don’t be greedy for petty gains and cause greater losses.

  Is "Spring Festival traffic broadcast" a virus?

  Content:"The Spring Festival is a long way to go home. What if the traffic is not enough? Urgent notice from the public security network supervisor: If you receive a message with ‘ "Spring Festival Traffic Broadcast" traffic collection package, I have received 4G traffic waiting for you to collect it … ’ Please don’t open it, but delete it immediately. If you open it, all relevant information in your mobile phone will be stolen. This is a new virus, and its danger has been confirmed, and anti-virus software can’t remove it. " Is it true?/You don’t say.

  Truth:According to some media, local public security departments have never released the information related to the "Emergency Notice of Public Security Network Supervision". However, the police also reminded everyone: Do not trust calls and text messages of unknown origin, do not click on unknown web links, and involve money-related information such as transfer and remittance, and ignore them. If the content itself contains links, it is likely to be phishing links and needs to be vigilant.

  "Eating melon seeds = drinking oil", is this true?

  Content:Melon seeds are one of the necessities for every family. However, there has been a rumor on the Internet that "eating melon seeds equals drinking oil" because the fat content of melon seeds is very high. Is this true?

  Truth:Nutrition expert Ruan Guangfeng said that this statement completely exaggerated the disadvantages of melon seeds. Judging from the current research, eating melon seeds properly is actually beneficial to health. Take sunflower seeds as an example, the fat content in every 100g of sunflower seeds is about 19g, while the daily edible oil recommended by Chinese Dietary Pagoda is only 25g — 30 grams Looking at this data, many people may think that eating melon seeds is really the same as eating oil. But in fact, although there is no essential difference between the fat we ingest from melon seeds and the fat we ingest from oil, it is somewhat exaggerated to say that eating melon seeds is equivalent to drinking oil.

  Is sugar really more terrible than drugs?

  Content:Candy, cakes and other sweets always make people want to stop, especially during the Chinese New Year holiday. But in recent years, many articles and film and television works have said that eating too much sugar will make people addicted and do more harm than drugs … … Is sugar really more terrible than drugs?

  Truth:Nutrition expert Ruan Guangfeng said that eating more sugar is not good for health, but "toxicity is greater than drugs" is purely exaggerated. Judging from the current research, eating more sugar is really bad for health. However, it should be pointed out that sugar here refers to added sugar, not naturally occurring sugar in food. Added sugar refers to sugar added to food, including sugar in honey and fruit juice. However, it does not include sugar found in natural foods, such as sugar in fresh fruits and lactose in milk. After evaluating the relationship between sugar intake and health, the World Health Organization believes that excessive sugar intake will increase the risk of dental caries and obesity, and obesity may increase the risk of other diseases. In the past, we didn’t say there was something wrong with eating sugar. In fact, it was because we used to eat less, but now we eat too much. But if sugar is more harmful than drugs and addictive, it exaggerates the harm of sugar.

  People who blush when drinking generally drink more alcohol.

  Content:"When I go home for the New Year, when I meet my relatives, friends and old classmates, I always get together for dinner. Drinking during the dinner is indispensable. I often hear people say," People who blush when drinking are generally able to drink a lot, because alcohol runs all over their faces and doesn’t go to their stomachs. " Is it true?/You don’t say.

  Truth:Zeng Jing, director of the Nutrition Department of Guangdong Armed Police Corps Hospital, said that under normal circumstances, alcohol (ethanol) is metabolized into acetaldehyde by alcohol dehydrogenase in human body, then turned into acetic acid under the action of acetaldehyde dehydrogenase, and finally oxidized into carbon dioxide and water. The contents of these two enzymes related to alcohol metabolism vary from person to person and are related to heredity. If the body lacks acetaldehyde dehydrogenase, the ability to decompose acetaldehyde is not strong, which will lead to acetaldehyde accumulation in the human body, and the capillaries on the face will expand, eventually leading to blushing. In fact, people who blush when drinking are not good drinkers. We should control the amount and degree of drinking, and don’t drink too fast, so as to control the process of alcohol entering the body and gain more time for body metabolism.

  It doesn’t matter if you can’t keep your mouth shut, as long as you exercise more afterwards?

  Content:It’s inevitable to eat and drink when you go home for the New Year. It doesn’t matter if you can’t control your mouth, as long as you exercise more afterwards?

  Truth:If you choose to treat yourself with a high-sugar milkshake and a muffin or other "healthy" snacks after exercise, your weight loss plan will not be completed in nine cases out of ten. If you can’t change your diet structure and only place your weight loss hopes on exercise, you are likely to become a healthy and strong fat man — — You are likely to gain some muscles, increase endurance and become healthier, but you still can’t shake off the numbers on the scale. Face the facts, people who want to lose weight! Without changing bad eating habits, you can’t lose weight by exercising alone. Exercise is important, but if you want to lose weight, you need a healthy diet, which is rich in enough fruits and vegetables, healthy fat and protein.

Fluorine chemistry: there is a big world in small elements

  Author: Hu Jinbo (Dean of Shanghai Branch of Chinese Academy of Sciences, researcher of Shanghai Institute of Organic Chemistry)

  The matter in the universe is composed of various chemical elements, among which there is a unique and magical element, that is, fluorine. The new fluorine-containing materials can make the Water Cube of Beijing Olympic Games and the China Pavilion of Shanghai World Expo shine brilliantly. Many new drugs contain fluorine atoms, and the display screens of mobile phones and computers also use liquid crystal materials containing fluorine … … Although fluorine chemistry has a history of more than 200 years, this "ancient" discipline is still full of vitality, and more new structures, reactions and functions are still being discovered, thus affecting and changing the world.

   Strange and important fluorine element

  Fluorine is not uncommon in life. The main swimming pool of the 2008 Beijing Olympic Games — — Water Cube, whose membrane structure is made of fluorine-containing materials — — Tetrafluoroethylene. This material has good corrosion resistance, heat preservation and strong self-cleaning ability, and is a new environmental protection material. Fluorocarbon coatings have also shined brilliantly in the Shanghai World Expo. The magnificent China Pavilion was sprayed with polyvinylidene fluoride fluorocarbon coatings, forming a gorgeous "China Red".

  In the international scientific field of fluorine chemistry, there are two words to summarize the importance of fluorine. The first one is unique. It is the most subversive element. Why can we use "most" to describe a chemical element? This is because fluorine is electronegative and its chemical properties are extremely extreme. This makes many fluorine-containing raw materials very active, but the fluorine-containing products are very stable — — When active fluorine-containing raw materials react chemically, they will release a lot of energy, but the fluorine-containing products obtained after energy release are particularly stable. This process is a bit like popcorn, which has experienced "explosion" and then settled down. Fluorine can also form the strongest chemical bond with carbon atoms, which makes fluorine-containing materials very stable. For example, Teflon, a plastic mesh, is one of the most stable materials.

  The atomic radius of fluorine is very small, which is also a major feature of fluorine. Using these three properties, many very unique and important fluorine-containing materials can be manufactured.

  The second word to describe fluorine is useful. 20% of the newly registered drugs in the world & mdash; 25% contains fluorine atoms. Some patients do PET— 18F— should also be used in CT examination; FDG, or fluorodeoxyglucose. Fluorine-containing liquid crystal materials will be used in the display screens of electronic devices such as mobile phones and computers.

  Fluorine-containing materials are also widely used in the field of national defense. In the aerospace field, gyro oil, high and low temperature lubricating oil and so on are all fluorine-containing materials. Fluorine-containing materials also occupy an important place in the advanced defense materials needed for atomic bombs.

  Fluorine-containing materials are so important, but it is strange that all the fluorine-containing materials that are useful to human beings at present are made by human beings relying on their own wisdom. Although there are many inorganic fluorides in nature, such as calcium fluoride, those that are useful to human society contain carbon — Fluorine (C— F) bond organic fluoride is very rare.

   A brand-new scientific viewpoint "negative fluorine effect"

  It is precisely because fluorine is so magical and has made such a great contribution to human society that understanding and mastering the scientific reaction law of fluorine chemistry and realizing the efficient synthesis of fluorine-containing organic molecules are of course the frontier fields of current chemical research.

  In this regard, China has made great progress. After more than 10 years of in-depth research and thinking, after further studying the fluoroalkylation reaction of alkylene oxide, the research team in China put forward a brand-new scientific viewpoint for the first time in the world — — "Negative fluorine effect", that is, the more fluorine atoms replace the center of carbanion, the nucleophilic reactivity of carbanion to many electrophilic substrates will often decrease. This view has been recognized by peers at home and abroad, and has been written into the textbook of Intermediate Organic Chemistry.

  Based on the new theory, our researchers have developed three types of more than 10 new fluorine chemical synthesis reagents, including sulfone reagent series, sulfoxide imine reagent series, difluorocarbon reagent and so on. These reagents based on "negative fluorine effect" have solved the problems of monofluoromethylation and difluoromethylation, difluoroenylation and difluorocarbon chemistry. These reagents have been used by more than 250 companies or research institutions for more than 528 times. American scientists have used these reagents many times when studying fluorine-containing biochemical active substances, and Japanese scientists have also used sulfoximine reagents among them. They all call these reagents "Hu reagents" in published papers.

  In the science of fluorine chemistry, there is still a big problem that is difficult to solve for a long time — — Fluorocarbon chain extension is easy to explode. In 2017, our research team made a breakthrough in this respect, and realized the reaction that one carbon in trifluoromethyl trimethylsilane catalyzed by sodium iodide changed into two carbons to form tetrafluoroethylene. The reaction was evaluated as "a breakthrough method for preparing tetrafluoroethylene" by the American Chemical and Engineering News.

  Subsequently, our research team also realized the extension of fluorocarbon chain from one carbon to two carbons and from one carbon to three carbons promoted by copper. This method of extending fluorocarbon chain can sweep away the original explosion hidden danger and can be extended controllably according to the wishes of researchers. In 2020, an Italian chemist wrote that it was a pioneer in this research direction.

  On the basis of these research results, the transformation of fluorine chemistry has also achieved remarkable results. Cooperate with related enterprises, China’s original fluorine chemical reagent — — Sulfoxfluor has realized the commercial production and sales in batches. Recently, a tonnage production process of fluorine reagent has also been successfully implemented. Prior to this, this reagent was sold by American companies around the world.

  These scientific research achievements of fluorine chemistry in China have achieved good response in the world. Pfizer, an internationally renowned pharmaceutical company, also took the initiative to invite our scientific research team to help solve the latest problem of drug production for cancer treatment. After half a year’s efforts, the two sides cooperated to solve the problem of efficiently introducing difluoromethyl into drugs.

  The future of fluorine chemistry science can be expected

  Based on the breakthrough scientific theory, coupled with the new reagents and reaction systems constructed from it, the current fluorine chemistry can develop more new fluorine-containing functional molecules for the country’s major needs and economic and social development.

  Take the purification of lithium as an example, the natural lithium resource — — The price of a ton of lithium carbonate is about 180,000 RMB at present, but after purification, the price of 99.9% lithium 7 in the international market is about 100 million RMB at present. If the purity is higher, what is the price of 99.99% lithium 7 in the international market? 230 million yuan/ton.

  It can be seen from the huge price difference that the difficulty of lithium purification lies. At present, the method of purifying lithium in the world is still the lithium 7 amalgam exchange method by American scientists in 1936. It takes 1000 tons of mercury to separate 1 ton of lithium isotope, and mercury is a toxic metal. Using mercury in such a large amount is not only costly, but also very harmful to the environment.

  As early as 1967, Chinese scientists put forward the idea of using organic methods to realize lithium isotope separation. After two generations of innovation, our younger generation of scientists stood on the shoulders of the older generation of scientists and followed this idea to invent a new fluorine-containing extractant, which greatly improved the stability and economy of chemical processes. At present, in the engineering development stage, with this new fluorine-containing extractant, we can purify the natural 92.5% lithium 7 isotope to more than 99%, which is the first time in the world to purify lithium by organic extraction. In the laboratory, 99.9% lithium 7 can be enriched to more than 99.99%, which is the first time in the world to be achieved by organic extraction, which has never been reported internationally before.

  This achievement is not only praised by scientists in China, but also considered as a very new green advanced technology after communicating with their American counterparts.

  After years of continuous innovation, China’s fluorine chemistry research has also won praise from international counterparts. In 2022, the American Chemical Society’s Chemical Creative Work Award was awarded to China’s team. Previously, our team had also won the fluorine chemistry award in royal society of chemistry. In the field of fluorine chemistry science, there have been three Nobel Prizes. Although this subject has developed for more than 200 years, it still has new vitality. This is because chemical science mainly lies in discovering new structures, new reactions and new functions, and a new generation of scientists can still create substances with unique structures and functions on the basis of predecessors, serving the society and benefiting the people. In the future, we will continue to work hard to make molecules create value, influence and change the world.
