　　On March 4th, the Supreme Leader delivered an important speech when attending the joint meeting of members of the Democratic National Construction Association and the Federation of Industry and Commerce of the Fourth Session of the 12th Chinese People’s Political Consultative Conference, comprehensively expounded our Party’s theoretical viewpoints and policy propositions on adhering to and improving the basic economic system under the new historical conditions, scientifically answered the most urgent and realistic major theoretical and practical questions in the field of non-public economy, and pointed out the direction for the healthy development of non-public economy in the new period and provided fundamental follow-up. We should thoroughly study and seriously understand the spirit of the important speech of the Supreme Leader, effectively unify our thoughts and actions with the central government’s major policies, and strive to build Zhejiang into a benchmark province for the healthy development of the private economy.

　　Strive to continue to be at the forefront in promoting entrepreneurial innovation, transformation and upgrading of the private economy.

　　It is a major policy established by our party to implement the basic economic system with public ownership as the main body and multiple ownership economies developing together. Both the public-owned economy and the non-public-owned economy are important components of the socialist market economy and an important foundation for China’s economic and social development. Comrade Supreme Leader reiterated that the position and role of the non-public sector of the economy in China’s economic and social development have not changed. Our principles and policies of unswervingly encouraging, supporting and guiding the development of the non-public sector of the economy have not changed. Our principles and policies of creating a good environment and providing more opportunities for the development of the non-public sector of the economy have not changed. These "three things have not changed" are in line with our party’s repeated emphasis on "unswervingly consolidating and developing the public sector of the economy" and "unswervingly encouraging, supporting and guiding the development of the non-public sector of the economy" and keep pace with the times, clearing the fog and eliminating the noise, conveying confidence more precious than gold to private enterprises and greatly inspiring their enthusiasm for entrepreneurial innovation. When the Supreme Leader worked in Zhejiang, he attached great importance to the development of private economy, designed a road map for the development of private economy in Zhejiang, and made a series of major decisions and arrangements. Under the cordial care and direct guidance of the Supreme Leader, the Zhejiang Provincial Party Committee insisted on drawing a blueprint to the end and consistently grasping it to the end, and the private economy flourished, setting off another development climax since the reform and opening up. At present,The role of Zhejiang private economy in the province’s economy can be summarized as "6789", that is, it pays about 60% of taxes, creates about 70% of GDP, contributes about 80% of foreign trade exports and provides about 90% of employment opportunities. It can be said that the private economy is the magic weapon for Zhejiang’s development, the golden signboard for Zhejiang’s external development and the source of wealth for Zhejiang people.

　　At present, the development of Zhejiang private economy has reached a new threshold, facing both rare development opportunities and many difficulties and challenges. We should unify our ideological understanding with the judgment of the CPC Central Committee with the Supreme Leader as the general secretary on the development situation, further strengthen our confidence, comprehensively implement the new development concept, vigorously promote the entrepreneurial innovation, transformation and upgrading of the private economy, and break a new world under the new normal of economic development. Carry out the concept of innovation and development, do a good job in scientific and technological innovation, support the establishment of a common technical service platform for private enterprises, run a good scientific and technological market, and comprehensively improve the overall innovation level of private enterprises. Implement the concept of coordinated development, do a good job in tapping the potential, support private enterprises to deeply participate in national strategies such as the construction of the "Belt and Road" and the development of the Yangtze River Economic Belt, carry out cross-regional mergers and acquisitions, guide private enterprises to develop cultural and creative industries, and promote key industries such as "civilian participation in the army" and "military conversion to the people". Implement the concept of green development, do a good job in ecological and environmental protection, encourage private enterprises to vigorously promote clean production and green manufacturing, apply new energy-saving technologies and new products, accelerate the development of circular economy, continue to eliminate backward production capacity, and resolutely rectify small workshops. Implement the concept of open development, do a good job in expanding the market, carry forward the spirit of grabbing food from tigers, make full use of the Internet platform, lead the global layout of the industrial chain value chain with internationalization, and lead the consumption trend with product innovation.Continuously increase domestic and international market share. Carry out the concept of shared development, do a good job in returning home, guide private entrepreneurs to closely link personal honor and disgrace, the rise and fall of enterprises with the changes in their hometown and the rejuvenation of the nation, further promote the return project of Zhejiang businessmen, and write a new chapter in the organic unity of "jumping out of Zhejiang to develop Zhejiang" and "returning to Zhejiang to develop Zhejiang".

　　Strive to continue to be at the forefront in creating a good environment and atmosphere for the development of private economy.

　　Since the 18th National Congress of the Communist Party of China, the Party and the state have launched a series of reform measures on the development of non-public economy, and formed a policy system to encourage, support and guide the development of non-public economy. Comrade Supreme Leader stressed that it is necessary to enhance the gold content and operability of policies; Ensure that all policies are fully implemented. In view of the phenomenon that the policy implementation is not in place, he clearly pointed out the outstanding problems such as "glass door", "spring door" and "revolving door", the iceberg of the market, the mountain of financing and the volcano in transition, and clearly proposed to focus on solving the "five major problems". This is of great guiding significance for us to better serve private enterprises and remove obstacles to the development of private economy. When the Supreme Leader was working in Zhejiang, he led the formulation of policies and measures to encourage, support and guide the development of the private economy, such as "Several Opinions on Promoting the New Leap of the Private Economy" by the Zhejiang Provincial Party Committee and the provincial government. In recent years, the Zhejiang Provincial Party Committee and the provincial government have launched many major reform measures in the administrative examination and approval system, commercial registration system, local financial system and market-oriented allocation of factors, creating a good policy environment and social atmosphere for the development of the private economy.

　　We should continue to conscientiously implement the principles and policies of the CPC Central Committee on the development of private economy, constantly improve the pertinence, effectiveness and operability of supporting measures, help enterprises "move three mountains" and "open three doors", promote the implementation of various policies, and thoroughly get through the "last meter". Resolutely liberalize market access, and encourage and support private capital to enter industries and fields that are not explicitly prohibited by laws and regulations; For basic public projects that can adopt market-oriented operation, it is fully open to private capital; All areas that allow foreign investment are open to private capital. Effectively reduce the burden on enterprises, do a good job of "cost reduction" in accordance with the requirements of supply-side structural reform, and truly reduce the institutional transaction cost, electricity and gas cost, logistics cost, financial cost, labor cost and tax burden of enterprises. Constantly strengthen policy propaganda, comprehensively sort out the policies and measures that have been introduced, simplify them, and make a list or brochure, so that private enterprises can see clearly and operate simply, and constantly expand the coverage of policy propaganda and the benefit of policy services. Efforts will be made to create a good atmosphere, continue to carry forward the spirit of "shop assistant", speed up the construction of public service system, and provide all-round and whole-process support and nanny and expert services for private enterprises, so that every private entrepreneur can invest with peace of mind, do things smoothly and start a business comfortably.

　　Strive to continue to be at the forefront in promoting the majority of non-public economic people to be qualified builders of Socialism with Chinese characteristics’s cause.

　　Promoting the healthy development of non-public economy and the healthy growth of non-public economic people is a major economic issue as well as a major political issue. The Supreme Leader stressed that the healthy development of the non-public sector of the economy depends on the healthy growth of non-public sector of the economy, and put forward that the majority of non-public sector of the economy should learn, educate and improve themselves and become qualified builders of Socialism with Chinese characteristics. When the Supreme Leader was working in Zhejiang, he clearly pointed out that Zhejiang businessmen should carry forward the spirit of keeping pace with the times and strive to be excellent builders of Socialism with Chinese characteristics. Private entrepreneurs in Zhejiang are the most active entrepreneurs in China. We should guide the vast number of private entrepreneurs to be strict with themselves with the ardent expectations of the supreme leader comrades, carry out in-depth education and practice activities of ideals and beliefs focusing on "abiding by the law, being honest and firm in confidence", attach importance to credit, morality and reputation, actively practice socialist core values, and be a model of patriotism, dedication, law-abiding management, entrepreneurial innovation and returning to society. Guide private enterprises to actively participate in activities such as "all enterprises help all villages" and "glorious cause", actively participate in social undertakings such as poverty alleviation and development, disaster relief, charity and so on, do more practical and good things to comply with public opinion, solve people’s worries and benefit people’s livelihood, and build a "monument" in the minds of hometown elders. Pay attention to the education and training of the younger generation of non-public economic people, and guide them to inherit and carry forward the entrepreneurial spirit of the older generation of entrepreneurs and the glorious tradition of listening to and following the party.

　　Building a good relationship between government and business is an important basis for promoting "two health". The supreme leader comrade proposed to build a new type of political and business relationship, stressed the need to grasp the standards of "pro" and "clean", and put forward requirements for leading cadres and private entrepreneurs respectively. The words "pro" and "Qing" are concise and unpretentious, but also rich in philosophy and meaningful, which hit the point of the current political and business relationship, pointed out the way for leading cadres and private entrepreneurs to get along with each other under the new situation, defined the boundaries and set the rules. When working in Zhejiang, the Supreme Leader pointed out that leading cadres at all levels should support the development of private enterprises on the one hand, and be pro-business, wealthy businessmen and safe businessmen; On the other hand, when dealing with entrepreneurs, we must have a sense of proportion, distinguish between public and private, and a friendship between gentlemen is as light as water. We should deeply understand these important expositions made by the Supreme Leader, practice the new relationship between politics and business with "closeness" and "clearness", and achieve "law", "square" and "boundary" in communication, so as to close the relationship between politics and business with "closeness" and standardize the relationship between politics and business with "clearness". For leading cadres, it is necessary to put "pro"The word "Qing" is regarded as a yardstick of diligence for the people and a clean and honest rule. It should not only be a "shop assistant" of private enterprises, but also establish and improve the regular communication mechanism between party and government leading cadres and non-public economic people, and do everything possible to help enterprises solve problems; We also pay attention to strengthening our own self-cultivation, being cautious about trivial matters, keeping the bottom line, keeping a good sense of proportion, preventing micro-duration, being uncorrupted, and not exceeding the law, discipline and personal gain. For private entrepreneurs, it is necessary to take the word "pro" and "clear" as the motto of communicating with leading cadres and the major principle of enterprise’s law-abiding operation. They should not only get rich, think about the source, serve the mulberry, actively communicate with party committees, governments and departments at all levels, tell the truth, tell the truth and make suggestions, and enthusiastically support the development of their hometown; Lead an honest and clean life, never cross the line, always take the right path, never pay bribes, and do business in a law-abiding and aboveboard manner.

　　Our reporter Cao Xiuying

　　"Charging anxiety" and "mileage anxiety" are a major obstacle to the large-scale industrialization of pure electric vehicles. At the 2019 World New Energy Vehicle Conference held recently, a technology called "High Specific Energy Fast Charging Lithium-ion Battery" won the Global New Energy Vehicle Innovation Technology Award.

　　This technology breaks through the technical bottleneck that graphite system can’t charge quickly. On the basis of maintaining the advantages of high energy density, high safety and long life, it can complete 100% charging within 15 minutes, ensuring the cruising range of electric vehicles of 300 kilometers.

　　What is the secret of this technology? How can we realize the fast charging of electric vehicles and make new energy users feel the convenience of "charging for five minutes and talking for two hours" like mobile phones?

　　At present, the fast charging methods in the industry have disadvantages.

　　As we all know, for pure electric vehicles, the charging and discharging performance of battery system is an important index to determine the actual use effect of vehicles. High energy density and fast charging ability are not only the technical direction that power battery manufacturers are constantly striving to develop, but also the core field of new energy technology.

　　"Lithium-ion batteries are also called rocking chair batteries." Cheng Xiaoyan, director of scientific research project of Contemporary Amperex Technology Co., Limited New Energy Technology Co., Ltd. (hereinafter referred to as Contemporary Amperex Technology Co., Limited), told the Science and Technology Daily reporter that the two ends of the rocking chair are the two poles of the battery, and lithium ions run back and forth at both ends of the rocking chair. When charging, lithium ions move from the positive electrode of the battery to the negative electrode through the electrolyte. Graphite, as a negative electrode, has a layered structure, and lithium ions are embedded into the graphite through the interlayer. The more lithium ions are embedded, the higher the charging capacity is.

　　A key index to measure the charging efficiency of electric vehicles is the charge-discharge ratio (C). The rate of charge and discharge can be simply understood as the rate of charge and discharge. The charge and discharge rate of lithium-ion battery determines how fast we can store a certain amount of energy in the battery or how fast we can release the energy in the battery. For example, when a battery with rated capacity of 100 A is discharged with 20 A, its discharge rate is 0.2C, and the used capacity is discharged within 1 hour, which is called 1C discharge; After 5 hours of discharge, it is called 0.2C discharge.

　　It is generally believed in the industry that fast charging of electric vehicles refers to the charging method with a charging rate greater than 1.6C, that is, the technology that takes less than 30 minutes from 0% charging to 80% charging.

　　As the name implies, to shorten the charging time, it is necessary to continuously improve the charging and discharging rate. The core of fast charging technology is to accelerate the speed of lithium ion moving between positive and negative electrodes through chemical system and design optimization. However, it is not enough to consider speed when developing fast charging technology.

　　During fast charging, lithium ions need to be embedded into the negative electrode instantaneously. This is a great challenge to the ability of the negative electrode to receive lithium ions quickly. In the battery of common chemical system, lithium and other by-products will appear in the negative electrode during fast charging, which will affect the cycle and stability of the battery core. Only negative electrode materials that can withstand fast charging and high current can be used to achieve fast charging.

　　Cheng Xiaoyan said that at present, lithium titanate and amorphous carbon are widely used as negative active materials in order to realize fast charging. However, both lithium titanate and amorphous carbon inevitably have the defects of serious shortage of energy density and high cost in practical application. The conventional design of increasing the amount of conductive materials will also affect the energy density of batteries. "In recent years, some manufacturers have begun to explore graphite as an active material, but the problem faced by graphite as a fast charging material is how to quickly release lithium electrons from the anode and then quickly enter from the cathode."

　　Cheng Xiaoyan explained that graphite is more like a highway. Although the energy density is higher, lithium electrons can only pass through in sequence.

　　In other words, graphite is not a natural material suitable for fast charging technology. "But we use technology to break through the bottleneck of the material itself, and its killer is ‘ Fast ion ring ’ And ‘ Superelectronic network ’ 。” Cheng Xiaoyan sighed.

　　The fast ion ring and the super-electron net accelerate the charging.

　　"We use graphite as the main material of the negative electrode, and innovatively use channel optimization and ‘ Fast ion ring ’ Technology, to create a circle of high-speed channels on the surface of graphite, so that lithium ions can be quickly embedded in any position of graphite, which greatly improves the embedding speed of lithium ions in the graphite cathode. Moreover, the modified graphite has the characteristics of super fast charging and high energy density, and there will be no by-products at the cathode during fast charging, which will affect the cycle and stability of the battery. " Cheng Xiaoyan said.

　　In addition, the technical team developed the "super-electronic net" technology to modify the cathode material, and combined with the crystal orientation and capacity excess coefficient of the anode and cathode plates to optimize the dynamic properties of the electrolyte and anode and cathode, so that the chemical system and battery design parameters can be optimally matched.

　　"Generally speaking, ‘ Fast ion ring ’ And ‘ Superelectronic network ’ It acts on the cathode and anode respectively, establishing a fast channel for a large number of lithium ions to flood into the cathode at the same time, and improving the diffusion rate of lithium ions. " Cheng Xiaoyan said.

　　In addition, in terms of mechanical parts design, the team creatively simplified the design of the battery cell top cover, set the electrode terminals to the side of the top cover plate and reduced the terminal thickness, significantly reduced the internal resistance, effectively controlled the heat generation of fast charging, and ensured the reliability of fast charging while improving the energy density by more than 5%.

　　"Our fast charging technology has 4C— 5C fast charging capability, achieving 10-mdash; 15-minute fast charging, compared with the fast charging system of lithium titanate cathode, has obvious energy density and cost advantages, and compared with other fast charging technologies in the industry which also use graphite as cathode, it can increase by 20%— 30% charging speed, and better cycle and weather resistance. " Cheng Xiaoyan said.

　　It has been successfully applied to more than 5000 buses.

　　At present, the super lithium-iron fast-charging battery developed by Contemporary Amperex Technology Co., Limited with fast-charging graphite as the main negative material has been applied to more than 5,000 electric buses, and the buses are in good running condition, which has been well received by vehicle manufacturers and bus users, and the battery has also been rated as "the best word-of-mouth battery for new energy buses" by the Ministry of Communications.

　　In addition to its energy density, the battery has a great advantage. In terms of cycle life, taking buses with harsh application conditions as an example, it is fully charged and discharged about twice a day on average. Roughly speaking, it can meet the operating requirements for 8 years, and the battery needs more than 5,600 cycles. The cycle life of super lithium iron battery cells can reach 10,000 times, which not only fully meets the operating needs of electric vehicles, but also can be used for energy storage and other cascade utilization after retirement, creating more economic value.

　　"In order to ensure the safety and reliability of the fast charging core, we have also developed special technology to identify the ‘ of the chemical system at different temperatures and SOC states. Healthy charging interval ’ , and then in this ‘ Healthy charging interval ’ Fast charging within the range can not only achieve fast charging, but also prevent the battery from being damaged by fast charging, so as to achieve fast charging, long cycle and safety and reliability. " Cheng Xiaoyan said.

　　In terms of weather resistance, in order to meet the requirements of low-temperature charging in northern winter and high-temperature working conditions in southern summer, the technical team specially developed an efficient thermal management system to ensure that the battery is in a reasonable temperature range. The battery core can be heated quickly at low temperature, and the fast charging mode can be started when the temperature meets the requirements; At high temperature, the system will cool down the battery, and truly achieve "all-weather" fast charging.

　　"We are developing 2C— with monomer energy density greater than 160 WHr per kilogram; 2.5C fast-charging lithium iron battery with high energy density and long life (more than 6000 cycles) is expected to be mass-produced by the end of 2019. At the same time, this technology has been applied and developed to the ternary system passenger car, which has achieved 350 kilometers of battery life and completed charging within 15 minutes. " Cheng Xiaoyan said that the company also plans to be in the next 1-mdash; Within two years, the ternary power battery product with energy density as high as 255 watt-hours per kilogram will be launched, which can be quickly charged within 18 minutes.

The box office of a single theater is 60 thousand dollars, and most of the film reviews praise the exquisite artistic conception of the picture.

In terms of old films, Shenwei has not diminished. In the fourth week, it pocketed $25.17 million, a decrease of only 39%. In 24 days, the local box office totaled $318 million, which is expected to surpass the total box office of $363 million, catching up with Marvel Comics (currently $380 million); At present, the global box office has reached $650 million, and after this week, it is expected to surpass ($665 million) to become the box office champion in American women-directed films. In the next week, the decline rate was 53%, which was lower than 60%, which was relatively stable. Now, the total domestic box office in 10 days totaled 99.8 million US dollars, and the total global box office was 141 million US dollars. Man-eating shark thriller is the best of the four films opened last week. Last week, it earned $7.43 million, a decrease of 34%, and the box office in 10 days totaled $24.26 million. The biography of Tupac Shakur, a famous late rapper, is really eye-catching, with a drop of 78% in the next week and a total box office of $38.64 million in 10 days. It seems that more profit margins have to be boosted by overseas.

The lowest overseas strong support scene in the first week of "Transformers 5" box office series

Recommended star rating: ★★★☆.

Obviously, blackening Optimus Prime is also difficult to retain the audience’s waning enthusiasm for autobots. Michael bay’s film, as the only film with a large-scale painting last week, earned $69.09 million in 4,069 theaters in the United States in five days (including $45.3 million in the box office from Friday to Sunday), which was only 57% of the previous film, making it the lowest box office in the series. Looking back, in the first six days of 2007, the box office was $155 million. In the first five days of 2009, the local box office was $200 million, and the box office was $180 million. The time was short, and it also collected $100 million in three days. The local box office peak of the whole Transformers series was the second film ($402 million), and then it continued to decline. However, in view of the fact that the next fastest heavyweight new film will have to wait until July 7th, there is still hope for the "online duration" of Transformers 5. If it exceeds Transformers 4: Extinction and Rebirth in 2014, the final domestic box office volume is expected to be around $140 million.

The rating on the Internet was a curse. Transformers 5 scored B+ in the current cinema, IMDb scored 5.3, MTC27 scored 27, the freshness of rotten tomatoes was 15%, and the freshness of audiences was 58%. The main points of spitting are as follows: 1. It turned out to be just a long and boring trailer of cheat people and a $250 million Hasbro toy advertisement. Rolling Stone magazine said: "It makes other blockbusters in summer look like classics of famous teachers." 2. I really don’t know what michael bay is for. "Certainly not praise, also won’t be the audience’s favorite, not to mention any innovation and development. Just to refresh the record of the number of bad reviews, come on, freshly baked another one for you. " 3. There is no wisdom or interest at all. "The Guardian" commented: "It gives people the feeling that it is a big scene with Marvel Comics, but Marvel Comics at least makes people feel humorous and interesting, and the Transformers are in short supply."

Although the word of mouth is not beautiful, the box office outside North America is still relatively optimistic. "Transformers 5" grossed $196 million overseas in its first week, topping the weekly box office list in 40 countries and regions around the world, with mainland China contributing $123 million. At present, the global box office totals US$ 265 million, which is slightly lower than the US$ 300 million in the same period of Transformers 4: Rebirth of the Jedi, but close to the US$ 271 million in the first week (the film has now reached 677 million in the global box office). I hope the influence of bad word-of-mouth can be controlled. After all, Paramount Pictures really needs Transformers 5 to be "normal" now. On the one hand, the production and publicity costs of this film add up to at least $350 million (data source: new york Times). On the other hand, several Paramount films, such as "The Ringing Bell at Midnight 3", "The Beach Ranger", are not satisfactory this year. If Transformers 5 can save the scene as expected, it will also give the executives and the capitalists a reassurance.

Next page:"Serious illness" has the highest box office in the year, and "Under the Peony Flower" is exquisite and favored.

Public Network reporter Zhou Wanyu reports from Qingdao

On the 11th, Qingdao Natural Resources and Planning Bureau released the latest "Pre-approval Publicity of Commercial Building Construction Project Design Scheme of plot LC0201-43 in Licang District". The project is located in the north of Heilongjiang Middle Road and west of Ganquan Road in Licang District, and Qingdao Haijing Hengchuang Real Estate Co., Ltd. is responsible for the construction.

According to the planning, the west side of the project is the residential area under construction-Yungu Jinmaofu, the north side is the commercial office land under construction, the southeast side is Chengjiaojia Road, and the east side is Haier Road Station of Metro Line 3. The total land area is about 2.88 hectares, including the existing commercial building (with a total construction area of 29,652.87 square meters) and a proposed commercial building. The proposed commercial building has five floors above ground (six floors locally) and three floors underground, with a total construction area of about 107,300 square meters, including 61,100 square meters above ground and 46,200 square meters underground. The design scheme of the proposed commercial building construction project was announced this time.

It is reported that in December, 2023, Xincheng Jianguan successfully signed a contract with Qingdao Junyi Holding Group & China Jinmao Investment Management Group, which ushered in the presence of Wuyue Plaza, a holding company of Xincheng, and brought Qingdao citizens a "one-stop fashion and quality shopping center" experience.

Special feature of 1905 film network　The live-action version released last weekend performed well, earning 300 million box office in three days. In the film, there are beautiful songs, beautiful dances, beautiful castles and beautiful costumes. The picture of Miss Watsons dancing in a yellow bubble skirt is simply beautiful! But the fly in the ointment is that our "big cousin" Dan Stevens’s Zhang Shuai face appeared for a minute.

May I ask the director, do you have a problem with our "Downton Tun" paper? Are you jealous of our big cousin’s prosperous beauty? Let’s take a quick look at the beautiful photos of our big cousin.

This "line of beauty" is a three-episode mini-drama produced by BBC, and friends who are interested in the rot drama can go and watch their big cousin at the peak of Yan value.

My eldest cousin has been filming for many years, and has been wandering around the small screen or acting as a walk-on for movies. At the age of 35, first hero, a popular Disney commercial film, finally got it. I didn’t expect to stand on stilts and wear muscle stuffing clothes to play against Miss Watsons throughout the filming. If what you see in the cinema is a dubbing version, it will be even worse. Even the magnetic voice and singing of the big cousin can’t be heard, and the only thing that can capture the imprint of the big cousin is those blue eyes.

But then again, when a fake like big cousin.·There are not a few situations in which the protagonist can’t show his face. The following small series will take you back.

I. Michael Fassbender in

What the hell is this? This is not the kind of big-headed doll that we often see in Chinese New Year! Behind this ridiculous and weird mask lies another guard. That’s our "French shark" Michael Fassbender (for the "heavy taste preference" of French sharks, please refer to our previous article "The Eight Diagrams of X-Men: The Mystery of One-America Divorce and the Heavy Taste of French Sharks" for details.）。

Frank, the protagonist of the film, is the lead singer of an English underground band and a talented psychopath. He has never taken off this headgear since he was 14 years old. Not only singing with a hood, but also eating with a hood. As a result, I can only eat liquid food, and I don’t even want to take off my hood in the shower. Therefore, the shark in the film can’t show its face at all except for the last few minutes.

What’s even more amazing is that the image of Frank is not fabricated out of thin air. He comes from Chris Sievey, a singer and actor who was very popular in Britain in the 1970s and 1980s. Sievey was first recognized by the public as the lead singer of a punk band The Freshies, and later turned to be a comedian, creating the comic image of Frank Sidebottom (yes, Frank) and being active on the small screen. Sievey died suddenly at the age of 54 in 2010, and jon ronson, the keyboard player of his band, wrote this play in memory of him.

In 2014, when he starred in "Frank", the French shark had already made it to Hollywood by waiting for other films, but he still starred in this small-budget cult film with his consistent love for literary films and independent films. And it turns out that despite wearing a hood all the time, we can still detect Frank’s cowardice, nervousness, brilliance and obstacles to self-identity from the body language of the shark.

Second, Hugo Weaving in

Among these faceless roles, if Hugo Weaving in "V for Vendetta" ranks second, almost no one dares to rank first (of course, Edward Harrison Norton fans may protest).

The film, adapted from the novel of the same name by Alan Moore, tells that Britain will become an authoritarian country with centralized system in the future, and the whole country will be shrouded in the white terror of the head of state Sutler. Hugo Weaving plays a mysterious anarchist V, who has an extraordinary physical quality because he was once used by a prison to do biological experiments. He escaped from the prison in a fire and was burned beyond recognition, so he wore a mask and never showed his true colors.

The film is a collection of "Fried Uncle", john hurt and many other British actors, as well as Natalie Portman, who just played the Queen in the prequel, but the most impressive thing is Hugo Weaving, who can’t show his face. Through his magnetic voice and profound lines, he showed a rich sense of hierarchy and unique texture, which made this rambling neurotic and idealist come to life.

Moreover, Hugo Weaving in those days was not the image of the elderly in today’s movies. After all, he was a man who played "bullet time" with the savior Neo in the movies and played the elf king in the movies. I don’t know if it is addictive to play such a faceless role. In 2011, he played the red skull in the movie, and he couldn’t show his face half the time.

Third, Edward Harrison Norton in

Ridley scott, a great American film director, has always wanted to make a film about the Middle Ages and knights. Finally, he realized this wish in the 2005 "Kingdom of Heaven". Based on the real history of the European Crusades, this film is a masterpiece in terms of script structure, cast and scene construction, but it is a pity that the whole film has no other highlights except Edward Harrison Norton.

Edward Harrison Norton has always been a powerful actor who won by acting, and he is always willing to choose some eccentric and paranoid roles. For example, baldwin iv of jerusalem in "Kingdom of Heaven" wears a silver mask in all the films because he has leprosy since childhood. However, Norton completed the last strong man of the Jerusalem dynasty, who was weak, sick, brave, resourceful and caring for the world, only by virtue of the shaping of his voice, which can be called an acting textbook.

Compared with those small fresh meat and flowers in China who have poor lines and don’t even recite lines, you will find that the gap between people is so big! Moreover, Edward Harrison Norton’s face value is not low, and people were even with Brad Pitt!

four、Lee Kwang Soo in

Lee Kwang Soo, the "giraffe" in Running Man, is also a sad advocate. He was bullied by various kinds in variety shows, and finally became a leading actor in a movie, but he could not show his face. In this film, he plays a young loser who takes part in a drug experiment, because the side effects of the drug actually turn his upper body into a fish. After being exposed by the media at first, he was regarded as an idol by the masses, but then the wind of public opinion changed and he became a disgusting devil and monster.

There are only two scenes of Lee Kwang Soo’s appearance in the whole film, and they are all in photos. During the filming, he spent 4-6 hours every day on special effects makeup, and then put on a fish head mask weighing 8 kilograms, not to mention eating, and even breathing was a problem. However, he explained this timid, cowardly and freedom-hungry role well.

The giraffe, who is 190cm tall and has been a model and has long legs, said, can’t I be a quiet handsome man? !

V. gerard butler in

Phantom of the Opera is one of the four major musicals in the world, the masterpiece of the musical master Weber. Since its birth 20 years ago, it has staged more than 70,000 performances around the world, with a box office of more than 3.2 billion, and won more than 50 important drama awards. Many people are confused about the difference between musical and Opera. Simply put, it is equivalent to the difference between pop music and symphony.

Four major musicals in the world

In 2004, this musical was put on the big screen, and the film was finally original. Not only did it reproduce classic tracks such as Angel of Music, The Phantom of the Opera and All I Ask of You, but even some transitions came from the musical version.

It’s really hard to connect Butler in Phantom of the Opera with him in 300 Warriors.

Of course, the most striking part of the film is the Phantom of the Opera played by gerard butler. The Phantom of the Opera has been wearing a mask for a long time because of his deformed appearance since childhood. For this reason, Butler spends four hours putting on makeup every day. He had never even seen a musical before he appeared in the film, but he had to undertake a lot of aria in the film. He only had 14 lines in the whole film, and all the others were sung. To this end, he found six vocal music teachers around the world to practice singing during the filming, and finally created an elegant and rough singing in the film, which overwhelmed many actors.

6. Daniel Wu in

Nowadays, Daniel Wu has simply become synonymous with handsome guy, and he is not the kind of "evil spirit" handsome guy that WeChat official account raved before. He has been trying to make the audience ignore his appearance. He tried to take the villain route, tried the action and kung fu route, and tried the sloppy and decadent image, but they failed to change people’s stereotype of him.

Last year, playing Gourdain in the Hollywood game adaptation blockbuster "Warcraft" finally satisfied Daniel Wu’s long-cherished wish. He finally did it. Although he knew that the role was played by him, he couldn’t relate him to Daniel Wu’s face when watching the film. Let the audience completely forget that the actors themselves project into the characters, which is also a realm of performance.

To this end, Daniel Wu also paid a lot. He attended a training class for more than a month and read a lot of information. And because Gourdain’s walking posture is different from others, when doing motion capture, he has been playing with others with a stance of "ma bu" or horse stance just look for four months in a row, and his legs are so thick that he can’t put on his original pants.

Back to the opening of Beauty and the Beast, this film expresses a truth that everyone knows — — You can’t judge a book by its cover. Inner beauty is the most important thing. The seven handsome actors mentioned above have practiced this point with their behaviors. They are not proud of their appearance, but rest on their laurels. Even when interpreting the roles that can’t be seen, they do their best without reservation. So they created characters that were deeply loved by the audience. Looking back at the chaos in the domestic film and television circle, it is simply embarrassing!

　　Recently, a whistleblower sent an e-mail to China Youth Daily, claiming that "Since 2004, Modernization of Shopping Mall began to collect money crazily, and within four years, the publishing fee income was tens of millions of yuan". CFP

　　In the past, when it was a core journal, the charging standard was 1,200 yuan per page. Now, it has been taken down from the sequence of core journals, and each page has been reduced to 600 yuan, with a discount. An editor of Shopping Mall Modernization told the China Youth Daily reporter: "If we have the opportunity to become a core journal again in the future, our price will rise back." (See this edition reported on April 22nd)

　　An academic journal is in such a different situation just because it has the words "National Chinese Core Journal" on its cover. Why is the selection of "core journals" so influential? What kind of interest pattern is behind the selection of "core journals"? In this regard, China Youth Daily reporter launched an investigation.

　　"Many people think it is a national standard."

　　The "National Chinese Core Journals" marked on the cover of "Shopping Mall Modernization" originated from Peking University’s "Overview of Chinese Core Journals" (hereinafter referred to as "Overview"-reporter’s note). In order to show its identity, Shopping Mall Modernization sometimes photocopies the Certificate of Selection of National Chinese Core Journals in journals.

　　"It is true that the evaluation results will be improperly understood and used," said Cai Ronghua, a research librarian of Peking University Library, one of the editors-in-chief of Overview. The research results of core journals presented in Overview can only be used as a reference, and if its role is not properly expanded, it will have a negative impact.

　　Cai Ronghua said that the editorial board even wrote this point into the "research report" in the front part of the "Overview" many times, saying that "core and non-core are only a relative concept, and it is wrong to exaggerate the role of core journals and use them inappropriately", and "calling on all sectors of society to correctly understand the concept of core journals, rationally use the list of core journals, and avoid negative effects caused by unreasonable use of core journals".

　　In the research report part of the 2000 edition of the Overview, the editorial board also highlighted in black: "Especially on the issue of evaluating professional titles, we must determine the’ list of important journals’ suitable for our unit according to the specific conditions such as the professional scope and academic level, and should not indiscriminately copy the list of core journals."

　　The "research report" also mentioned: "It is obviously unreasonable for professionals of different levels and different natures to use the same core periodical list to evaluate their professional titles. The value of the core journal list lies in that it can face different levels of users with different needs, and users’ reference’ the core journal list and select the journals they need after screening is the correct way to use the core journal list. "

　　Xing Dongtian, editor-in-chief of the General Office of China Academy of Social Sciences, has made an in-depth study of Peking University’s Overview. He believes that this appeal may not be effective under the background of "judging articles by journals" in China’s academic circles at present.

　　He said that quite a number of scientific research institutions stipulate that only papers published in "core journals" can be regarded as assessment results. "This regulation makes no sense, because the level of journals is not necessarily related to the level of papers. However, this typical practice of’ judging articles by journals’ is the reality of academic evaluation in China. "

　　Ceng Wei, director of the editorial department of Higher Education Research in Huazhong University of Science and Technology, also believes that evaluating professional titles is equivalent to reading papers, while the quality of papers is equivalent to the level of published journals, while the level of academic journals is equivalent to whether they have been selected as "core journals".

　　Xing Dongtian said that this is because it is often difficult to identify what level a paper is, especially those theoretical achievements that cannot be tested at the moment. "But if it is evaluated by what kind of publication it is published in, it is clear at a glance and it is very convenient to operate."

　　"There is such a simple and easy way, and the scientific research management department can’t ask for it. Is there any reason why the ready-made tools are not used?" Xing Dongtian said that The Overview is not a national standard, but only a scientific research achievement of bibliometrics, but most scholars who know little about bibliometrics simply don’t know how the core journals are selected.

　　"No matter the executive department or the assessed, it is regarded as a mandatory evaluation system, and many people even think that it is a national standard. In fact,’ core journals’ have become the basic indicators of academic evaluation in China. " Xing Dongtian said.

　　Every review season, editors frequently conduct public relations.

　　Qian Ronggui of Nantong University Magazine pointed out in his monograph "Core Periodicals and Periodical Evaluation" that whether a publication is a "core periodical" under current conditions is directly related to its own survival and development. If a journal is selected as the "core journal", the source of manuscripts and financial resources will come one after another. However, if it is not selected, it will be followed by the scarcity of high-quality manuscripts and the shrinking of high-quality authors, and the whole editing and publishing work will become difficult.

　　Since the evaluation results of core journals will have such a great impact, its evaluation process will inevitably be interfered by relevant interest groups.

　　"As a folk research behavior, there is nothing wrong with Peking University Library to make such an evaluation. Peking University has its own standards, and other institutions can have other standards, and no one has the right to interfere. But the key point is that today’s academic evaluation system links core journals with many real interests, objectively expands the function and influence of core journal evaluation institutions, and there is the possibility of’ power rent-seeking’. " Xiong Bingqi, a professor at Shanghai Jiaotong University, told the China Youth Daily reporter.

　　Cai Ronghua admits that the evaluation of core journals every four years is a series of "public relations" and "anti-public relations" processes.

　　Every review season, many editors-in-chief of academic journals have found research groups to mobilize classmates, fellow villagers, teachers and friends and other people to intercede. Because for them, whether a publication can enter the sequence of "core journals" may be related to the issue of "life and death": once it is listed, its value will increase sharply; And if the publication is in the "core" sequence, but it is "removed" by the new edition of "Overview", it is like rolling in the deep.

　　Because Modernization of Shopping Mall was not included in the 2008 edition of Overview, the page fee was reduced by half, which shows the scale of interest disputes caused by Overview.

　　"They (referring to the editors-in-chief of academic journals-reporter’s note) keep looking for us again and again, and we need several people to receive them," Cai Ronghua said. But she also pointed out that in the last few months, the research group will be closed and no one will receive it.

　　An Xiumin, an associate researcher at ISSN China National Center, told China Youth Daily reporter that at the end of 2008, just before the publication of Overview (2008 edition), she often received phone calls from her friends, and even a friend told her in a nearly pleading tone that if the core was not evaluated, the unit would not be allowed to do it, and the unit would not allocate money, so I should be laid off.

　　An Xiumin said that in the face of such a situation, many journals try their best to get into the circle of core journals.

　　A journal that is quite influential in the industrial and economic circles has been in the "core journal" sequence of Overview before, but it was pulled down in the latest edition of Overview in 2008. The editor-in-chief of the journal showed a short message sent to him by a university professor to China Youth Daily reporter: "Editor-in-chief, I didn’t expect your journal to be rated as a core journal, which is beyond most people’s expectation. This will be disastrous for the development of our engineering management discipline. Please do something to remedy it!"

　　The editorial board has received sponsorship fees for selected publications.

　　The huge economic benefits behind "Overview" are even reflected in the pirated market.

　　At the beginning of 2008, before the book was published, the "List of Core Journals Selected in 2008 Edition and Book Subscription Notice" began to circulate on the Internet, so that the editorial board had to issue a special statement on the homepage of Peking University Library on March 11th: "This achievement has never been published on the Internet, and the various versions of the" Overview of Chinese Core Journals "which are popular on the Internet at present are not published by the project team … The so-called 2008 published online at present.

　　It is understood that the 2008 edition of the Compendium of Chinese Core Journals, although less than 1,000 pages, is expensive and priced in 360 yuan.

　　Cai Ronghua claims that the research group will not be disturbed, because it is useless for those who want public relations to come to the research group and can’t solve any problems. The research group is only responsible for collecting and sorting out data. "Data is a past tense, and no one can change it."

　　Because the evaluation of "core journals" is divided into two parts: quantitative evaluation and qualitative evaluation, Cai Ronghua admits that the qualitative evaluation part, that is, the part evaluated by experts, is uncontrollable to some extent and "may exploit loopholes". "We will send invitations to a large number of experts to participate in the review, but basically only a quarter of the experts are willing to participate in the review. Actually, we are not completely clear about which expert."

　　She said that during the evaluation process, there will be periodical agencies to inquire which experts will participate in the evaluation. "If the experts participating in the review are bribed by the periodical press, there is nothing we can do. But in order to prevent this, we have adopted the method of increasing the number of experts participating in the evaluation. A magazine can’t afford to bribe more than half the experts, can it? "

　　Cai Ronghua said that some journals did offer sponsorship in the selection, but the editorial board refused. "It’s not good to take someone else’s money and not evaluate others." She stressed that in the later period, "our staff members were isolated, turned off their mobile phones and did not receive visiting periodical agencies."

　　However, she admits that in the previous selection, the jury has received sponsorship fees from some core journals, but the number is generally small and voluntary. As for the specific amount of sponsorship fees provided by these magazines, Cai Ronghua did not elaborate further, but said, "In return, we will give each other a" Overview of Chinese Core Journals ".

　　She said: "There are also many journals that ignore us, but they are still among the core journals in every selection."

　　As for the financial support, Cai Ronghua told reporters that the research group has no special funding support, but the Peking University Library and the university libraries participating in the selection will have some support. There are hundreds of people who regularly participate in the research and development work, most of whom are university library staff. Most of them do research for free, and only the income from the publication of Overview is divided into several hundred yuan each.

　　Cai Ronghua said that because the evaluation of core journals has attracted much attention, there is great pressure, not only financial pressure, but also social pressure. "In the future, we must be strict with ourselves and let the evaluation results stand up to scrutiny."

　　Variation of "Core Journals"

　　"Nowadays, academic journals are directly linked to the actual interests," Ceng Wei said. There are many core journals, not only one from Peking University, but also another core. "If you get a core, you can charge a publishing fee, and business will be good."

　　It is understood that, in addition to the General Survey published by Peking University, the Comprehensive Citation Report of China Academic Journals published by Tsinghua University Library, China Academic Journals (CD-ROM Edition) and China Scientific Literature Metrology and Evaluation Research Center, the Citation Index of Chinese Social Sciences (CSSCI) developed by Nanjing University, and the Outline of China Chinese Social Sciences Core Journals developed by China Academy of Social Sciences are all making similar evaluations.

　　In addition, some educational and scientific research institutions have formulated "core journals" that meet their respective requirements on the basis of referring to various versions of "core journals".

　　Xing Dongtian told the China Youth Daily reporter such a story:

　　He used to work in the China Academy of Social Sciences, and all the journals of world religious studies were called World Religious Culture. The orientation of this journal is: a popular and knowledgeable religious culture publication for the general public and religious believers, and it is the only popular religious culture magazine sponsored by academic circles in China at present.

　　To his surprise, when he visited a teacher in a famous university, he suddenly found that World Religious Culture was also among the "core journals" recognized by the university.

　　"How can such an intellectual journal be a core journal?" Xing Dongtian thought it was ridiculous, so he called the scientific research department of the school and learned that it was reported by the religious department of the school.

　　However, the teacher he visited complained bitterly: "There are very few publications in our discipline. If we don’t report them, the evaluation will be very disadvantageous. The unqualified assessment involves our rice bowl problem. "

　　"In this way, the system forced them to include" popular and knowledgeable "publications in the scope of core journals," Xing Dongtian sighed.

　　Cctv news(News Network): In the face of the current epidemic situation, all localities have implemented detailed prevention and control measures to accelerate vaccination in COVID-19.

　　In Anhui, the local authorities actively allocated vaccines to ensure smooth and orderly vaccination. As of 0: 00 on the 16th, Hefei had received a total of 2,815,700 doses of vaccine. More local medical staff were sent to reduce the waiting time of the people in line.

　　Up to 12: 00 today (May 16th), a total of 15,396,300 people have been vaccinated with COVID-19 vaccine. In addition to more than 180 existing vaccination clinics, Beijing has set up more than 390 temporary vaccination sites supported by large public places such as gymnasiums and convention centers, with a daily vaccination capacity of more than 400,000 doses.

　　Beijing also launched the vaccination command and dispatch platform, which realized the dynamic monitoring of the whole process of vaccine production, distribution, storage and vaccination.

　　In order to improve the efficiency of vaccination, Shanghai has set up 70 large-scale vaccination sites, and at the same time accelerated the entry of vaccines into temporary vaccination sites such as construction sites, parks and communities.

　　Starting today, Shanghai will carry out six nucleic acid tests on new immigrants during quarantine observation and community health monitoring.

　　Accelerate the construction of immune barrier, Guangdong strengthens the connection between vaccine supply and demand, and each vaccine takes only 2 hours from storage to storage; Hengyang, Hunan province, drove the mobile vaccination vehicle into the countryside; A mobile vaccination service team covering all towns and villages has been set up in Linyi, Shandong Province, focusing on providing on-site vaccination for people living in remote villages.

　　In Shijiazhuang, Hebei Province, in order to facilitate the workers in the construction site to be vaccinated, the local area specially set up evening vaccination; Yunnan has stepped up vaccination in border areas. The target population of COVID-19 vaccination in 25 border counties and cities is 4.07 million, and the coverage rate of the first dose has reached 97.4%.

　　Statistics released by the National Film Bureau show that the box office of summer movies this year has reached 17.8 billion yuan, exceeding the total box office of summer movies in 2019 and reaching a record high. Domestic films have obvious advantages in leading, with a market share of 86.15%, which is also a record high.

　　Why do more and more people like watching domestic movies? The "outbreak" of the summer box office has node factors and the accumulation of time, so it is now accumulating. Behind the high popularity and high box office, there is such "high density" data:

　　The script of "The Trilogy of Gods" has been polished for nearly five years, with two years of preparation in the early stage. The subtitle of "The First Part of Gods: The Song of the Wind" lasted for nearly three minutes, and the names of about 10,000 cast members flashed on the screen.

　　More than three years’ production cycle, an original team of nearly 300 people, and an industry support team of nearly 1,000 people have supported the appearance of more than 10,000 small characters "in the same frame" in the complete landscape of Chang ‘an Three Wan Li … …

　　Behind a series of figures is the change and gradual landing of a whole film production process. The first part of Feng Shen achieved a new breakthrough in the genre of mythical epic films. The animated film Three Wan Li in Chang ‘an showed the classic charm of China’s Tang poetry across time and space with a unique narrative, and The Eight-Corner Cage was a new attempt at sports movies. The exploration of difficult and diversified genre films has entered a new stage, which has spawned new production processes and production standards. The large-scale advance screening before the official release of the film has become the "new operation" of the film industry this year. This year, the Spring Festival, May Day, Dragon Boat Festival and summer vacation files are almost hot, and every round of growth in the film market is driven by high-quality films.

　　The film industry chain is more and more detailed, which reflects the efficient empowerment of science and technology and promotes a qualitative leap. Digital technologies such as artificial intelligence, 5G, big data and cloud computing are integrated with film production, changing film production methods and management processes. Motion capture, virtual shooting, 3D printing, etc., more than 20 new jobs were born in this decade, and new IP and new tracks were developed.

　　China’s films are "more emboldened" because of the iterative cycle of experience of one work after another and the accumulation of new experience through new practice. Artificial intelligence technology was applied to the production process of Wandering Earth 2, "filling the technical gap in this field in China"; The hair and expression of the kangaroo in Moon Man are enough to be "confused", and the difficult biological visual effect production is made in China. Consolidate artistic imagination with rich details, activate imagination and creativity, and open up new expressions and new spaces for domestic films.

　　The seeds of innovation and creativity, rooted in the excellent culture of China and the fertile soil of China reality, can blossom and bear fruit. "Oriental Aesthetics" has become a key to the success of this summer movie. Previously, The Wandering Earth put forward the "China Plan" to walk with the earth, and the animated film Deep Sea pioneered the three-dimensional form of "particle ink painting", which presented the sea scene with ink painting with hundreds of colors, all of which contained profound Chinese cultural genes. In recent years, many unique jobs in the film industry have appeared, such as etiquette instruction and folk custom consultant, which also reflect the pursuit of film in cultural connotation and professional details.

　　"Deep cultural heritage+high degree of film industrialization", Zhang Yan, executive director of the Asian and Chinese Film Research Center of Beijing Normal University, believes that technology serves the art, which guarantees the pursuit of style and the level and imagination of the film. Large-scale trend traction, technical aesthetics, image wonders, etc. all bear Chinese’s cultural values within the popular framework.

　　The film’s "opening way" is full of new ideas, which greatly boosts industry confidence; Tell the story of China well, and show cultural self-confidence in "national tide" and "national wind". From this self-confidence, seeing the cultural pattern and tolerance of China and the new height of film industrialization in China, we should respond to the audience’s eager expectation for excellent works with high-quality creation.
