In the first quarter of 2020, the "home life" without going out disrupted the normal life rhythm of Chinese people and brought more opportunities and challenges to the online entertainment industry.

On April 20th, Yuewen Group, an online literature platform, released a national report on the production and consumption of online literature in the first quarter. According to the data, more than 300,000 people chose to become online writers in the first quarter and produced more than 500,000 online literary works. Among them, the number of new authors in Hubei ranks sixth in the country for the first time. During the "city closure" period, Hubei people wrote more than 13,000 online works.

Hubei author’s works are growing rapidly, and short content is the first choice for testing water.

It is reported that in the first quarter of 2020, the number of new authors on the platform was 330,000, an increase of 129% from the previous month; Among them, people in Guangdong, Jiangsu, Shandong, Henan and Sichuan love online writing, while Hubei Province ranks among the Top6 for the first time, and the enthusiasm of local people for online writing is unprecedented.

A large number of new authors poured into the platform, which directly promoted the further diversification of content creation. Yuewen Group said that the number of new works in the first quarter exceeded 520,000, an increase of about 1.5 times year-on-year. Fantasy is still the "good heart" of most writers. However, "short content" has also shown a rapid rise, with the number of "short stories" increasing by nearly five times year-on-year. In the first quarter, the two themes of "short stories" and "light stories" which were small in the past climbed to the second and fourth respectively.

The data shows that young users are the most creative, and writers under the age of 30 account for more than 70%. Combined with popular creative works, it is not difficult to see that most new authors were not professional authors before, short and pithy content became the first choice for testing water, and the online text industry has become an important income-generating channel for "slash youth".

In Hubei, which has attracted much attention, writing by homebodies has become an important way for Hubei people to entertain themselves and seek a second income. The number of new authors has also shown a rapid growth trend, and it ranked sixth for the first time in the ranking of new authors in the first quarter of this year. According to the data of Reading Group, during the period of "closing the city", the number of authors in Hubei increased by nearly 10,000, and the total number of new works in Hubei exceeded 13,000, an increase of 170% from the previous month, far higher than the national average. Similarly, in terms of creative themes, the theme of "short stories" is also the first choice for new authors in Hubei.

Both old and new websites are favored, and writers and netizens chat while watching them.

"Can write and love to read", the number of platform users and the average usage time of the Reading Group in the first quarter have increased to varying degrees. Among them, the number of users in Hubei increased by 28% year-on-year, and the reading time of users increased by 43%.

In terms of popular content, warm, humorous and realistic online articles have become the reading trend, which also shows the enthusiasm and optimism of the people all over the country in the face of the epidemic. During the period, Madam, your waistcoat has dropped again, which was annoying by platinum writers of Reading Group, became the favorite work of the most users. In 2019, the western fantasy work "The Lord of Secrets" broke many reading records at the starting point, followed closely, and the popular Xian Xia male frequency online article "My brother is too steady" ranked third.

The long-term value of IP content of some classic websites is further highlighted. Taking Joy of Life as an example, with the popularity of scriptwriting at the end of 2019, the popularity of original works continues to rise, and the total reading time of users in the first quarter ranks second in the whole station. This website that has been completed for more than 10 years is still loved and sought after by the public.

In addition, the trend of "spitting while watching" and "social comment by paragraphs" is more and more obvious among this group of readers. In the first quarter, the number of new comments on the platform works of Yuewen exceeded 50 million, up 62% from the previous month, and the text barrage "social comment by paragraphs" became the favorite social tool for young users, with the number of new comments exceeding 35 million. Spitting, urging and making suggestions, readers’ "brain holes" have also become an important source of inspiration for the author.

1905 movie network news In 2019, the most popular country man officially released the theme song "Nezha" MV, which was jointly sung by hip-hop singer GAI and Da Tiao. The theme song specially selected hip-hop style, which is in line with the high-burning Nezha spirit of "not accepting fate" in the film. Recently, in the first batch of advanced viewing activities held in Beijing, the film won the highest score of "five stars for all" and the super-high comment of "close to perfection". The film has both laughter and crying. There are more than 43 times of laughter at the scene, and the scenes related to father-son love make some viewers "cry two tissues". It can be seen that it makes sense that Ne Zha was selected as the first domestic animated film to land in IMAX cinema. The advance screening of the film was opened this weekend and officially released nationwide on July 26.

The strength gives voice to interpret "unwilling fate". So what if the new Nezha was born as a demon

The theme song "Nezha" shows the "teardrop subversion" of the new Nezha from many angles through the protagonist’s monologue: as a "rebel" deeply rooted in the hearts of the people, unlike the audience’s previous cognition, Nezha’s resistance has changed from "killing himself with tears" to "fighting with fate to the end" today, full of juvenile stubbornness. The MV revealed a high-burning bridge section, and Nezha’s head was tilted by the falling sky. Even so, it could give birth to three heads and six arms, and the audience shouted "burning"! This change in Nezha is, to some extent, a change in the beliefs of a generation.

In addition, the MV also shows the story behind Nezha’s "rebellion": Nezha, who looks fearless, tries his best to be recognized by the world. Nezha’s bitter experience captured many tears from the audience, much like every teenager who has experienced or is experiencing rebellion in reality.

At the same time, the unyielding temperament of hip-hop itself is also in line with the theme of "not accepting fate" in the film, just as the lyrics say, "Then let me put all my eggs in one basket and don’t want to spend my days in the dark." For the film itself, GAI was even more excited after watching the movie and said "I like it very much."　

Make with heart, get "full marks" from netizens, control details and create summer masterpieces.

Recently, the film held its first foreign screening in Beijing, which won the audience’s "super high score" real name Amway. One is funny. The movie Ne Zha has a lot of comedy elements, and the plot is full of jokes. According to statistics, the first batch of people laughed at the scene for about 43 times. Secondly, it’s easy to cry. In the film, some fragments about the affection between Li Jing and Nezha’s father and son made many audiences cry. Thirdly, the exquisite interpretation of the theme of "not accepting fate" made the film "ignite" the hearts of many live audiences "burning is not stupid, but cool is really cool", praising its completion, plot, picture, special effects and music, and bringing many "subversive surprises" to the audience.

The production of the film lasted more than three years, and the number of shots in the film was over 5,000. Finally, less than 2,000 shots were "selected" and presented on the big screen, with special effects shots accounting for 80%, in order to show the audience the most perfect "new" Nezha. The production of every shot in the film is excellent. For example, the two parts of Nezha’s "Fire Lotus" and Ao Bing’s "Water Column" revealed in this MV are groundbreaking in animation. It took nearly half a year only in the development stage, and in the formal production stage, the special effects artist repeatedly revised it day and night, which achieved the best effect now.

The film Ne Zha will land in the national cinema on July 26th.

CCTV News:In two months, hundreds of pet dogs died strangely, with the same symptoms and painful death methods, which aroused the vigilance of many pet dog owners in Dalian. They visited repeatedly in areas with high incidence of pet dog poisoning and finally found an important clue.

Many pet dogs have been poisoned (network map)

The key to uncover the truth is this pet dog named Dahuang. Rhubarb is a stray dog adopted by Ms. Wang. On October 24th, Rhubarb played in front of Ms. Wang’s shop as usual.

Ms. Wang, a Dalian citizen:At that time, I was working in the house, and the dog took the medicine there. At that time, the neighbor found it and said that the chicken liver was wrapped in yellow pills.

The experience of rhubarb quickly spread among pets, and everyone quickly rushed to the scene to find clues. Finally, they found a surveillance camera of a lottery station on the side of the road, and this camera just recorded the whole process.

Ms. Li, a citizen of Dalian:Now the suspect appears, with a cigarette in his left hand and something in his right hand. You see, he threw something in this position, and then he turned to see if the dog would eat it. He specially waited for the rhubarb to eat what he threw, and he stayed here for 15 seconds to wait for the rhubarb to eat it.

The owner of the lottery shop next to him found that what Rhubarb ate was very suspicious. In association with the recent pet dog poisoning incidents, the lottery shop owner took out what Rhubarb had in his mouth. Two hours later, rhubarb showed symptoms of shortness of breath. This shows that there is something wrong with the yellow tablets taken by rhubarb.

Veterinarian Zhao Yingzhi:Through these cases, our experience in treatment and some information we checked, we suspect that it is an anti-tuberculosis drug.

Reporter:Is this medicine for people or dogs?

Veterinarians:For human use, anti-tuberculosis drugs, because there is no enzyme to resist this drug in dogs, so as long as they eat a little, they will be poisoned.

Fortunately, rhubarb didn’t eat much, but it finally survived after emergency rescue. The experience of rhubarb and the surveillance video confirmed the suspicion of pet dog owners for the first time. It is true that some people deliberately poisoned and killed dogs, and the poisons were carefully selected.

Veterinarian Zhao Yingzhi:There is no specific medicine, and it is recorded in the data that vitamin B6 is injected in large quantities, but the clinical effect is not particularly obvious through us.

The reporter learned that on August 8 this year, there was an article on the Internet that introduced the use of this drug to kill cats and dogs. Although this article was later reported and deleted by animal protection groups, the methods introduced in the article still spread. What is more serious is that this medicine is not only harmful to pets, but also a threat to people, especially children.

Veterinarian Zhao Yingzhi:Adults may not have a big problem, but if they are children, they will definitely have problems. Because children are small in weight, taking one tablet of this medicine may cause problems. This medicine should be a prescription drug.

At present, the police in Dalian have accepted the reports of pet dog owners. It is understood that the police have merged several poisoning cases and the case is currently under investigation.

Have you noticed that there has been a lot of good news from operators recently?

It is also a port number transfer network, and it is also vying to get on VoLTE.

One of them, Xiao Lei, has been waiting for a long time-the mobile phone number supports remote account cancellation.

This policy not only saves time but also saves money. (After all, the trip home can cover your phone bill for several years.)

Yes, you heard me right.

From January 1st this year, all three major operators can cancel their accounts in different places.

Xiaolei wants to praise Unicom most, and he went online to cancel his account early, so we don’t have to run the business hall again.

As for mobile telecommunications, it is a little more difficult.

Last week, Mobile began to pilot online account cancellation. But if you open China Mobile App, you probably can’t find the account cancellation entrance, because it is only limited to Shaanxi Mobile number for the time being.

Mobile number and telecom users in other areas can only go to the business hall to handle it.

(account cancellation entrance: China mobile App→ classification → life → online sales number)

Lei doesn’t know when it will be open to the whole country. Before that, mobile phone users should take a look at the preparations first …

Method for cancel number of mobile telecommunication in different places

Listen, to cancel the number in the business hall, you need:

I bring my ID card and service password and go to the designated business hall to handle it.

Not all business halls can do it.

Take Guangzhou, where Xiaolei is located, as an example. Only the business hall can close the account in different places.

(An authorized agency like this won’t do)

So before you go, be sure to call 10086/10000 to find out which business halls can do it.

But, you can’t just cancel it if you go.

Your mobile phone number cannot have the following conditions:

Arrears;
Have a contract;
It is bound with services such as family number and broadband.

Only one situation:

At the time of inquiry, Xiao Lei found a secret, and the method of canceling the account between Mobile GSM and M-Zone Shenzhouxing was actually different.

The customer service explained this to me:

You must go to the business hall to make an appointment to cancel your account. If you don’t pay for the next 90 days, you will automatically sell the number;
And Shenzhouxing and M-Zone will automatically cancel the number if the arrears exceed 90 days.

You don’t pay your phone bill for 90 days. How can there be such a big difference?

Under the coercion of Xiao Lei, the customer service told Xiao Lei:

Because GSM is prepaid, arrears will affect credit, so you have to make an appointment to cancel your account;
However, Shenzhouxing and M-Zone are post-paid, and how much is charged, even if the arrears are directly thrown away, it will not affect the credit.

In other words, Shenzhouxing and M-Zone don’t have to go to the business hall to close their accounts.

Fortunately, little ray asked, and saved you another thing?

In a word, Xiao Lei suggests that you call 10086/10000, where you belong, to find out your account cancellation conditions, so as not to make a trip in vain.

If there is a Shaanxi mobile phone friend who is reading this article, the account cancellation process on the mobile App is similar to that of China Unicom, and Xiao Lei said it together.

Unicom remote number cancellation method

Xiao Lei cancelled a Unicom number in January.

The entrance is easy to find:

"Mobile phone business hall App → service → handling → account cancellation"

First of all, we have to go through the triple verification of "SMS verification code+uploading ID photo+face recognition". The ID card must be taken now, and photos in the photo album cannot be used.

I can’t help it. I have to prevent others from maliciously canceling your number.

At this time, China Unicom will remind you that the phone bill should not be less than 50 yuan, otherwise it may not be possible to cancel the account ~ (Mobile can cancel online as long as it does not owe money at that time)

In order to close the account successfully, Xiao Lei gritted his teeth and charged the phone bill again.

Of course, the extra money will be refunded to you.

It is only by transferring to the balance of another Unicom number in the same province.

For example, the number of Xiaolei Guangdong Unicom cannot be transferred to Jiangsu Unicom.

Just when I crossed my heart and thought I was done, huh? ? ? Unknown error. What the hell? !

Ray suddenly felt struck by lightning.

No way, find customer service! When I opened Unicom official website and found that there were only two people waiting in line, Lei was secretly pleased.

The problem is that miss customer service can’t solve the problems that Xiaolei encountered, and finally she just gave a complaint feedback link …

Just when Xiaolei was disheartened, ready to give up and went directly to the offline business hall to cancel the account, he suddenly had a flash of light and thought of the key to the problem: Unicom’s mobile phone card number is divided into 4G and 2 G and 3 G.

Generally, 4G numbers belong to China Unicom’s national system CBSS, while many 2 and 3G numbers still belong to local provinces and cities BSS. The two card systems are not connected, so naturally they cannot be transferred.

And the number I want to transfer to is the 3G card!

Sure enough, Xiao Lei changed the number to a colleague’s 4G card, and it was a success.

Almost a month later, the balance was directly charged to the number I filled in.

In addition, Unicom also provides a way that it likes very much-just don’t.

However, if you want cash, you can do it. You have to go to Unicom’s own business hall to cancel the number, and support bank card transfer to refund the balance.

It should be noted that the donation fee is non-refundable, and only the money that you recharge can be refunded.

In contrast, the refund of mobile telecom is very pit.

Lei asked the customer service:

At present, there is no uniform standard for telecommunications, and whether cash can be refunded depends on local policies;
Mobile can only transfer the balance to the mobile number of the same attribution, and cannot refund cash.

Although mobile tries to save the user churn rate by raising various thresholds.

But now there is a remote account cancellation+port number transfer, and it is not a simple matter of who we want to use.

I asked if you were afraid.

Wait a minute! Don’t go after reading the article!

Xiao Lei made a small questionnaire, which is related to you. Used to optimize the article and let you see more interesting content.

　　The educational function of chemistry course is mainly reflected in four aspects: first, to impart basic concepts and key abilities and to discriminate scientific facts; The second is to enlighten scientific thinking and methods and solve real problems; Third, cultivate scientific spirit and quality, and understand the value of disciplines; Fourth, carry forward the patriotic spirit and establish a sense of responsibility and mission to serve the motherland. As a key link in education, the college entrance examination must also implement the fundamental task of cultivating people by virtue, give play to the correct educational orientation of the examination, and give play to the core functions of cultivating people by virtue, selecting materials for service and guiding teaching.

　　Change ideas and jump out of the cycle

　　Looking back over the years, the real questions of the national chemistry college entrance examination are mostly around the major themes of the times and the frontier achievements of chemistry in social life, carefully selecting situational materials such as daily life, production and environmental protection, academic exploration and experimental exploration, focusing on the main contents of the subject, innovating the presentation methods of test questions and information, and highlighting the examination of information sorting ability, critical thinking ability, dialectical thinking ability and language expression ability, which not only examines students’ academic accomplishment and key ability, but also gives play to the educational value and role of chemical science.

　　The common problems in the review process of senior three in general schools are "four stresses and four despises": attaching importance to teaching AIDS and neglecting teaching materials; Pay more attention to knowledge than thinking; Emphasis on answers, light process; Re-explain, light experience. Especially in the last month before the exam, many teachers often adopt the mode of "practice+comment" and "exam+comment", which leads to the boring and ineffective state of students desperately brushing questions and teachers correcting and explaining, leading to physical and mental fatigue and anxiety of teachers and students.

　　In the final review stage, chemistry teachers should change their ideas and jump out of the cycle of "practice+lecture+examination". Through in-depth research on the real questions of college entrance examination, tracing back to the source, and linking the key topics, hot knowledge topics and innovative functional test questions through "theme", the textbook knowledge and problem-solving methods are reconstructed, so that students can build their own knowledge topics and find the focus and breakthrough points of review.

　　Grasp the main content

　　The main contents of high school chemistry include basic concepts and research methods, material structure and properties, chemical reaction principle, preparation and application of inorganic substances, experimental basis and scientific inquiry, organic synthesis and application. Linking textbook topics through themes is to consciously combine the knowledge of each major section to make them interrelated and mutually confirmed. The teaching theme is constructed by creating situations, which makes the original knowledge in students’ minds modular and functional, and promotes the synchronous improvement of students’ knowledge and ability. For example, when reviewing the related contents of salt hydrolysis and weak electrolyte ionization, the following teaching flow can be designed:

　　Summarize the learned hydrolysis reaction → the basic form of salt hydrolysis reaction → understand that it is weak to hydrolyze from the perspective of double decomposition reaction → take CH_3COONa as an example to analyze the relationship between the hydrolysis equilibrium constant of CH_3COOH and the ionization equilibrium constant of CH_3COOH → the weaker it is, the more hydrolyzed it is → analyze the acidity and alkalinity of the mixed solution with the same concentration of ch _ 3cooh and CH_3COONa by combining the equilibrium constant. The acidity and alkalinity of the mixed solution of HCN and NaCN with the same concentration → the comparison of ion concentrations in the two groups of solutions → the analysis of the acidity and alkalinity of the solutions of NaHCO_3, NaHSO_3 and KHC_2O_4 and the concentration of related particles combined with equilibrium constants.

　　When reviewing elemental compounds, students should be guided to understand the properties of elements, their simple substances and compounds with their structures and principles. For example, it emphasizes the influence of chemical bonds and intermolecular forces on the properties of matter, and establishes a channel between micro and macro through the forces; Design a teaching theme with change view under the guidance of balance thought, and deeply understand elements and their compounds, electrochemistry, energy, equilibrium movement and other issues; This paper analyzes chemical phenomena and problems from macro and micro levels as well as qualitative and quantitative perspectives.

　　Generally, the test questions of chemical reaction principle take continuous reaction or parallel reaction (competitive reaction) in industrial production as situational material, and mainly examine enthalpy change (material accounting, energy accounting and economic accounting), chemical equilibrium constant (the problem of material equilibrium transformation), chemical reaction rate and industrial production safety, and mainly analyze it from two angles of balance and rate. The chemical equilibrium is calculated with the equilibrium constant as the core, and the chemical rate mainly analyzes its influencing factors, and finally returns to the temperature for adjustment. For example, in electrochemical review, students should focus on the ionic behavior in electrolyte solution.

　　In the review of experimental chemistry, it is best to choose the preparation of substances to design thematic teaching, because this is the most complete process. Let students fully understand the purpose, method, result and conclusion of the experiment. The core is separation and purification, the focus is on the operation specification, and the difficulty is the principle behind the operation. This requires students to learn from and use the basic experimental methods in middle school chemistry according to the basic principles of the experiment, give priority to the analysis of the material system as the first element of the experiment, and fully consider the restrictive conditions such as experimental equipment and drugs, experimental requirements, experimental safety, tail gas treatment, method selection and other issues to complete the design, analysis or evaluation of the chemical experiment.

　　Cause analysis of wrong questions

　　In the review teaching, in addition to the above topics, we can also carry out the theme teaching of students’ wrong questions and cause analysis. From the perspective of problem solving, subject core literacy is the comprehensive quality and key ability of students in the process of solving real, meaningful, complex and even unpredictable situational problems by using the knowledge and skills obtained from subject courses. In teaching activities, guiding students to carry out comprehensive analysis, practice model cognition and evidence reasoning according to the knowledge of material structure and nature, basic concepts and basic principles in real problem situations can promote the development of students’ understanding of chemical problems, and then realize the development from chemical subject knowledge to chemical core literacy. The selected related questions should be more exploratory, active, practical, open and hierarchical, so as to fully reflect its function of improving students’ comprehensive ability to use chemical knowledge to solve practical problems. In the process of analyzing test questions, we should analyze students’ answers, especially the language expression, thinking and standardization of answering questions, refine students’ feedback, make full use of feedback information, sort out difficult questions, find deep-seated reasons, check for missing items in time, and construct theme teaching through model analysis of test questions to improve review efficiency. (Zhou Xuegong, a researcher and senior teacher of Haining Teacher Training School, Zhejiang Province)

CCTV News:The World Health Organization has designated the last week of April as "World Immunization Week", and this year’s theme is "Vaccine makes us closer". The reporter learned from National Health Commission yesterday (28th) that in order to prevent cervical cancer, China has started the pilot human papillomavirus vaccine, that is, the free vaccination of HPV vaccine in some areas.

At the National People’s Congress in 2020, many deputies called for free HPV vaccination for school-age girls in China as soon as possible. In February this year, National Health Commission publicly replied that it would promote the pilot project first, encourage qualified areas to actively adopt various financing models, and gradually carry out free HPV vaccination. Just a few days ago, Erdos, Inner Mongolia, launched the city-wide HPV vaccine free vaccination project, with the city’s 13-mdash; 18-year-old women can get three shots of HPV vaccine free of charge at designated medical institutions only by paying the vaccination service fee. Guangdong province also said recently that it is actively studying the free vaccination of HPV vaccine for school-age girls.

Zhao Fanghui, Director of Epidemiology Department of Cancer Hospital of China Academy of Medical Sciences:The first way is to enhance the public’s correct scientific understanding of HPV vaccine and cervical cancer and vaccinate as soon as possible; The second way is to promote from the national or government level, and bring HPV vaccine into the immunization program as soon as possible. I think this is also the best way to improve the coverage of HPV vaccination.

The vaccination of girls aged 9 to 14 in China is less than 1%

Last November, led by the World Health Organization, 194 countries around the world, including China, made the first commitment to eliminate cervical cancer by 2030. At present, cervical cancer is the second largest female malignant tumor in China, and the number of new cases in China is around 110,000 every year. In the past two decades, the incidence and mortality have been increasing year by year, and they are getting younger.

Zhao Fanghui, Director of Epidemiology Department of Cancer Hospital of China Academy of Medical Sciences:We found that this younger age is the average in the past. The average onset of cervical cancer may be in the 60 s, but now it can reach the age of 40 or 50. Of course, some patients are younger, and they will also suffer from it in their twenties. From our point of view, it will be about 5 years earlier than 20 years ago.

HPV vaccination is one of the most critical measures to prevent cervical cancer, and another key measure is cervical cancer screening. With the birth of HPV vaccine, cervical cancer is expected to become the first malignant tumor that can be completely eliminated. The standard recommended by WHO is that 90% of girls should complete HPV vaccination before the age of 15, but many countries, including China, are far from meeting this standard.

Bivalent and tetravalent vaccines have provided most protection.

The data show that more than 99% of cervical cancer is related to human papillomavirus, that is, HPV persistent infection. After the whole process of HPV vaccination, it can provide enough protection for women, and there is no doubt about the effectiveness and safety of the vaccine. At present, there are four kinds of HPV vaccines approved for marketing in China. How to choose and fight?

The four approved HPV vaccines include two bivalent vaccines, a tetravalent vaccine and a nine-valent vaccine. The valence mentioned here refers to the type of virus, so simply speaking, the multivalent vaccine is how many types of HPV virus can be prevented. The suitable age for bivalent and tetravalent vaccines is 9-mdash; 45 years old, the suitable age for nine-valent vaccine is 16-mdash; 26 years old, all four vaccines need three shots. Since the price represents the type of virus, is it necessary to vaccinate high-priced vaccines to play a better protective role?

Zhao Fanghui, Director of Epidemiology Department of Cancer Hospital of China Academy of Medical Sciences:There are fourteen types of high-risk human papillomavirus that cause cervical cancer, among which the most common types are 16 and 18, which will cause more than 80% of cervical cancer. Therefore, bivalent and tetravalent vaccines cover 16 and 18 types, and the nine-valent vaccine has five additional types besides the 16 and 18 most important types. Two-valence, four-valence, and nine-valence may sound very different in numbers, but in fact the difference is 10%— Between 15%, bivalent inoculation can avoid cervical cancer with high probability.

The incidence of malignant tumor increases and the mortality decreases.

Yesterday (28th), the Beijing Cancer Prevention and Research Office officially released the Annual Report on Cancer Registration in Beijing in 2020. This is the first time that Beijing has publicly released the cancer monitoring data of its residents in the form of an annual report.

The Annual Report summarizes the 2017 tumor registration data submitted by 168 secondary and above medical institutions in the city, and analyzes the incidence and death of 23 common malignant tumors, the different characteristics of male and female incidence spectra, and regional differences. According to the Annual Report, there were 50,070 new cases of malignant tumor among registered residents in Beijing in 2017, with an overall incidence rate of 367.88/100,000, with an average annual increase of 2.11% in the past 10 years. The mortality rate is 191.38/100,000, with an average annual decrease of 1.06% in 10 years.

Ji Jiafu, Dean of Peking University Cancer Hospital:Although the incidence rate has increased, the mortality rate has decreased. First, it is related to the corresponding and relevant policies issued by the government, encouraging early screening; The second is that with the improvement of education level, people’s attention and awareness of their own health are increasing. Therefore, the tumor was discovered earlier. Although it was discovered, the cure rate was relatively high and the mortality rate decreased.

The data show that the top five diseases in men are lung cancer, colorectal cancer, liver cancer, gastric cancer and prostate cancer, and the top five diseases in women are breast cancer, lung cancer, thyroid cancer, colorectal cancer and uterine body cancer.

11. What are the contraindications for vaccination?

A: At present, there are contraindications to any vaccination except rabies vaccine. The usual contraindications are those who are suffering from serious organ diseases, especially those in active stage; Acute infectious diseases are fever; Children with immune deficiency can’t be vaccinated with live vaccine because they are allergic to vaccine ingredients. When there are clear contraindications, it is really impossible to vaccinate, and vaccination should be carried out after the vaccinated object is ill.

12. Can vaccination guarantee that you will not get sick?

A: All vaccines have a certain protection rate, but due to the individual differences of the recipients, a few people will not have a protective effect after vaccination, and they may still get sick. Another case is the coupled disease. If the recipient happens to be in the incubation period of the disease targeted by the vaccine at the time of vaccination, the disease will still occur after vaccination without protective effect.

13. How to compensate for the abnormal reaction of vaccination?

A: Vaccination is a public health measure. While protecting the health of the vast majority of people, very few people bear the risk of abnormal reactions. Taking full account of the rights and interests of the recipients, the Regulations on the Administration of Vaccine Circulation and Vaccination stipulates that those who have suffered serious damage due to abnormal reactions shall be given one-time compensation, and the specific compensation measures shall be formulated by the people’s governments of provinces, autonomous regions and municipalities directly under the Central Government. The compensation expenses for abnormal reactions caused by Class I vaccines shall be arranged by the provincial finance, and those caused by Class II vaccines (self-funded vaccination) shall be borne by the production enterprises.

Abnormal reaction is inevitable because of the inherent characteristics of the vaccine itself; The occurrence of abnormal reaction is a small probability event; It is neither caused by vaccine quality problems nor by implementation errors, and no one is at fault. Through vaccination, an immune barry is established to protect that recipient and the people around the recipient. Therefore, it is not compensation to give certain economic compensation to the recipients.

14. Do you need routine screening before vaccination?

A: The contraindications of each vaccine are different and have their own special contraindications. General contraindications can only be judged by inquiry or simple physical examination, and it is impossible to screen all contraindications, and the screening cost is expensive; Routine screening of all contraindications before vaccination is not recommended internationally.

15. What will be the impact of public doubts about vaccine safety?

A: If the public’s confidence in vaccines and vaccination declines, it may lead parents of children to refuse to vaccinate their children. Without vaccination, the vaccination rate of the population will decrease, the immune barrier of the population will decrease, and the corresponding infectious diseases may break out.

For example, in Nigeria in August, 2003, some people claimed that polio vaccine (OPV) was unsafe and would lead to infertility of children in adulthood. This has led to the cessation of polio vaccination in two northern Nigerian States, and the proportion of polio vaccination in other States has also dropped significantly. As a result, polio broke out in northern Nigeria. The outbreak eventually paralyzed thousands of children in Nigeria and spread the disease to 19 other polio-free countries. Many children had to face the tragedy of lifelong disability, which could have been avoided by vaccination. In addition, countries such as Japan and Britain have also resisted vaccination because of the dissemination of false information about vaccination. The consequence is that there is an immune gap and a loophole in the immune barrier of the population, which leads to the outbreak of vaccines against infectious diseases.

16. What problems should parents pay attention to before children are vaccinated?

A: Parents should take their children to qualified vaccination clinics recognized by government departments for vaccination. Before vaccination, they should truthfully provide the vaccinators with the health status of the recipients so that the staff can judge whether they can be vaccinated. Parents should pay special attention to whether their children have acute diseases, allergies, immune insufficiency, nervous system diseases, etc., and cooperate with vaccination under the guidance of vaccinators. For example, before the newborn is vaccinated, parents need to cooperate with the vaccinators, do a good job in inquiring about the newborn’s health status and general health examination, and provide the newborn’s health status, including whether it is full-term delivery at birth, birth weight, newborn birth score, congenital birth defects, whether it is suffering from a certain disease, etc., so that the vaccinators can correctly grasp the contraindications of vaccination and decide whether to vaccinate. If you find anything suspicious after vaccination, you should immediately consult the vaccination staff and seek medical treatment if necessary, so as to get timely and correct treatment.

17. Under what circumstances are children not suitable for vaccination?

A: Acute disease: If parents find that their children have a fever, especially those with a fever above 37.6℃, or children with other obvious symptoms at the same time, they should suspend vaccination. After the child recovers and nursed back to health for a period of time, he will be vaccinated. In addition, if the child is in the onset or recovery period of an acute disease, or in the acute attack period of a chronic disease, the vaccination should be postponed until the child recovers.

Allergic constitution: individual children have allergic constitution, which is easily ignored by parents. Children with allergic constitution may occasionally cause allergic reactions after vaccination, resulting in adverse reactions. The so-called allergic constitution refers to children’s repeated contact with a certain substance, which is prone to allergic reactions and corresponding symptoms, among which allergic skin rash is the most common. If it is found that allergic reactions have occurred in the past, vaccination should be stopped.

Immune insufficiency: It is generally believed that children’s immune insufficiency is not only worse than that of healthy people after vaccination, but also easy to cause adverse reactions, especially when vaccinated with live vaccines. Serious immune insufficiency includes immune deficiency (such as agammaglobulinemia/hypogammaglobulinemia), leukemia, lymphoma, malignant tumor and so on. If children are prone to recurrent bacterial or viral infections, often accompanied by symptoms such as fever, rash and lymphadenopathy after infection, the possibility of immune insufficiency should be suspected, and special care should be taken when vaccinating.

Nervous system diseases: It is dangerous for people with nervous system diseases to get some vaccines, so it has been confirmed that children with nervous system diseases, such as epilepsy, encephalopathy, hysteria, encephalitis sequela, convulsions or convulsions, should be carefully vaccinated under the guidance of doctors.

18. What is the probability of coupling disease during vaccination?

A: Take children’s coupled illness as an example. According to the survey of health service demand in China, the two-week prevalence rate of children aged 0-4 years old is 17.4%. Therefore, even if the vaccination is safe, about 17 children out of every 100 vaccinated children will suffer from other diseases in the next two weeks. Although the diseases have nothing to do with vaccination, they are easily misunderstood as abnormal reactions to vaccination because the time is closely related to vaccination. Take the coupled death of newborns vaccinated with hepatitis B vaccine as an example. The mortality rate of newborns (0-28 days) in China is 10.7‰, and the number of children born every year in China is about 16 million. Based on this calculation, about 170,000 newborns die every year in China, which means about 466 newborns die every day. According to the regulations of China’s hepatitis B vaccine immunization program, hepatitis B vaccine should be vaccinated within 24 hours after children are born. Based on the national vaccination rate of the first dose of hepatitis B vaccine in time (within 24 hours after birth) of 75%, about 350 newborn deaths are vaccinated every day, that is, there may be 350 cases of coupled deaths in newborns vaccinated with hepatitis B vaccine every day in China.

19. How do we classify vaccines in vaccination management in China?

A: According to the Regulations on the Administration of Vaccine Circulation and Vaccination promulgated by the State Council in 2005, vaccines are divided into two categories in China.

The first category of vaccines refers to vaccines provided by the government to citizens free of charge, which citizens should receive in accordance with government regulations, including vaccines determined by the national immunization plan, vaccines added by the people’s governments of provinces, autonomous regions and municipalities directly under the Central Government in the implementation of the national immunization plan, and vaccines used for emergency vaccination or mass vaccination organized by the people’s governments at or above the county level or their health authorities. The second category of vaccines refers to other vaccines that are inoculated by citizens at their own expense and voluntarily.

Incorporating the second type of vaccine into the first type of vaccine mainly considers the degree of harm to public health caused by diseases that can be prevented by the vaccine, the effect and safety of the vaccine, the production and supply capacity of domestic vaccines and the financial burden of the government. The first kind of vaccines are generally used to prevent common infectious diseases that seriously endanger children’s health, infectious diseases with relatively high morbidity and mortality in China, and diseases that are generally included in immunization programs in other countries and diseases that are eliminated or controlled globally.

20. What are the management requirements for vaccination services?

A: The Regulations on the Administration of Vaccine Circulation and Vaccination promulgated by the State Council in 2005 stipulates that the medical and health institutions designated by the health authorities of the people’s governments at the county level in accordance with the regulations shall undertake the vaccination work. Vaccination units are required to have a medical institution’s practice license, a practicing physician, a practicing assistant physician, a nurse or a rural doctor who has passed the vaccination professional training organized by the health department of the people’s government at the county level and passed the examination, and a cold storage facility, equipment and a cold storage system that meet the standards for vaccine storage and transportation management.

In order to standardize the vaccination management, the former Ministry of Health promulgated the Code for Vaccination Work, together with the State Food and Drug Administration, promulgated the Code for the Management of Vaccine Storage and Transportation, and also formulated a series of rules and regulations, which set clear technical requirements for vaccine planning, warehousing management, cold chain management and vaccination services. According to local needs, local health administrative departments have formulated corresponding working rules and organized daily work assessment.

Cdc centers at all levels are responsible for technical guidance of vaccination and immunization planning, and undertake the monitoring and control of vaccines against diseases, formulation of vaccine demand plan of national immunization planning, management and maintenance of cold chain, distribution and guidance of vaccines, monitoring of suspected abnormal reactions to vaccination, monitoring of vaccination rate, personnel training and social publicity and mobilization. Grass-roots vaccination units are responsible for the vaccine and cold chain management of their own units, establish vaccination certificates and vaccination cards for school-age children, and provide vaccination services in accordance with the immunization procedures formulated by the state.

So far, the top three domestic box offices.

1905 movie network news 　　According to statistics, as ofeightmoontwelveJapan Saturday,2017The cumulative box office in the mainland has broken through in.364Compared with the same period last year, the total growth rate is close.55Billion. Among them, domestic films performed strongly at the beginning of the year and in the summer — — With the help of waiting for the film, the Spring Festival filesevenTianjingtun33Billion,seven、eightThe moon was born again.Wolf Warriors2》And other explosive works. Finally, accumulate28More than 100 million domestic films won183Billion box office, in the past weekend, the successful realization of imported films.181The overtaking of billions of data.

　

Domestic films surpassed imported films "Wolf Warriors 2" and "Fast 8" in the box office.

　

In 2017, the mainland box office had exceeded 36.4 billion as of the evening of August 12, a substantial increase of nearly 5.5 billion compared with the same period last year. Among them, domestic films made more than 18.3 billion at the box office, higher than the 18.1 billion imported films. From the analysis of specific data, the peak of the market appeared in February, and the box office in that month climbed to 6.18 billion with the help of many films in the Spring Festival. In the week of the Spring Festival holiday alone, the mainland market swallowed more than 3.3 billion. The summer file that just passed followed in July with 5.04 billion yuan, and the box office increased by nearly 500 million yuan year-on-year. Domestic films are also the most outstanding in these two periods, and almost all the top ten box office paintings are concentrated in this period.

　

The overall box office climb is also inseparable from the performance of a single film. As of press time, in 2017, 54 of the new films released in the mainland exceeded 100 million at the box office and 12 exceeded 1 billion. Of the over 100 million films, domestic films account for 28, with a slightly higher proportion than imported films. There is no doubt that the champion of the overall list is the record-breaking Wolf Warriors 2, with a single contribution of more than 4 billion at the box office, while the champion of imported films is 2.67 billion at the box office, and Kung Fu Yoga starring Jackie Chan ranks third with 1.75 billion.

National Day movies are highly competitive.

　

The National Day file and the New Year file are ready to go. The annual box office is 50 billion or no suspense.

　

In August, "Wolf Warriors 2" rewrote the long-lost box office record in film history, and became the new overlord of the mainland film market with an unshakable 4.2 billion box office. At the same time, the film’s hot performance also detonated the summer file that was slightly weak in the first half and revitalized the market. Such a strong momentum naturally makes us have more expectations for the film market in the second half of the year.

　

According to the news that has been exposed so far, there are many kinds of Chinese films that will meet the audience in the second half of the year, including modern military themes that are favored by the market at present, comedies and fantasy films that have always been popular with the audience.

　

In addition, several film directors — — Xiaogang Feng, Chen Kaige and Yuan Heping will all return to the battlefield with their works. Xiaogang Feng’s new film will be the first to be released during the National Day. The film is based on the cultural and art troupe in the 70 s and 80 s, restoring the former director memories of youth; At the end of the year, Chen Kaige’s works and those directed by Yuan Heping and supervised by Tsui Hark are scheduled. The former is based on the story of a demon cat stirring Chang ‘an in the prosperous Tang Dynasty, while the latter focuses on a fantastic Jianghu adventure in the Uber-ridden era.

　

Judging from the release time, the above-mentioned Chinese works will strongly occupy the National Day file and the New Year file, which are also the two most important golden files in the mainland film market in the second half of the year. According to the current growth trend of the broader market, with the strong help of the National Day and New Year movies, it is very likely that the total box office will exceed 50 billion in 2017.

　　"Time has taken away youth, and years have eroded pride. Once a teenager, he is now in a hospital bed. This is the life course that each of us must go through. When you are old, who will be with you … …” The reading of this sitcom is straightforward, and it also puts forward a realistic and urgent proposition: providing for the elderly.

　　A few days ago, the sitcom "Sunflower", which was performed by the "post-90 s" nurses in Hudong Nursing Home for the Aged in Yangpu District, was performed in Shanghai for some medical staff. Sunflower tells the true story of young nurses in this nursing home for the aged. Here, the "post-90 s" nurse team is the main force of nursing, and 13 young girls account for half of the nursing staff in the hospital. The oldest is 27 years old and the youngest is 23 years old. They take care of another group of "post-90 s", those old people in their eighties and nineties.

　　When you treat the old man as your closest relative, your fear will dissipate.

　　"My name is Ni Luyan, born in 1991, and I have worked in Hudong Nursing Home for the Aged for six years. Perhaps it is because I took care of my grandparents who were lying in bed since I was a child. When I filled in my volunteers for the senior high school entrance examination, I did not hesitate to choose the nursing major of Yangpu Health School. " Ni Luyan said that after graduation, she was assigned to Hudong Nursing Home for the Aged as she wished, and faced more "grandfathers and grandmothers" and found that "reality is not a fairy tale".

　　In this nursing home for the aged, the average age of the elderly is 85, and there are many elderly people in their 90s. Most of them suffer from chronic diseases such as coronary heart disease, diabetes and sequelae of cerebral infarction, which lead to disability and dementia of the elderly. They have little ability to express clearly and lack the necessary reaction ability. This is the biggest difference between nursing homes and nursing homes.

　　Grandma Xu in a ward is a patient who is difficult to care for by Ni Luyan. When she was admitted to hospital because of sequelae of cerebral infarction, her face was very thin and she had many pressure sores on her body. Blister sores are particularly easy to break, as long as they are broken, the wound will be eroded. When the illness was serious, Grandma Xu had as many as 16 blisters all over her body, and 40% of her skin was broken. Broken blister sores are often accompanied by thick yellow liquid flowing out, giving off a pungent smell.

　　The smell made the elderly living in the same ward ask for a room change, and the nursing staff resigned one after another. Even the family members of the elderly did not want to stay long, so they left with a few words during the visit … … All this, the old man saw in his eyes, so he has been depressed and unwilling to cooperate with the treatment.

　　"When these strangers are regarded as close relatives, the inexplicable fear and loss will be dispelled by a determination." Ni Luyan took care of the elderly.

　　The stench of wound ulceration is prohibitive. Ni Luyan and her colleagues wear "thickened masks" with multiple layers of gauze. More than 50 pieces of gauze are used for each dressing change, and it takes an hour or two. They keep bending and standing for an hour or two, and concentrate on treating the wound. In order to make the old people clean and comfortable without peculiar smell, this group of nurses should change the medicine for Grandma Xu at least twice a day, four or five times a day. Dressing in winter, the elderly are afraid of the cold, and several nurses set up a "small tent" on the hospital bed with quilts and bamboo poles to keep warm and avoid the contact between broken skin and clothes.

　　Everything comes to him who waits, and with continuous nursing, the blister gradually closes up until it disappears. A smile appears on the lost old man’s face, and he jokes and amuses with the nurse every day, just like a different person.

　　The "painter" nurse painted 200 pictures in five years, knocking on the soft heart of the old man.

　　What is the most important thing in nursing work? Fu Rong, a young nurse, blurted out, "Skilled." Bu Lina, the head nurse of Hudong Geriatric Nursing Home in Yangpu District, smiled and shook her head and said, "It is the temperature passed down from hand to hand."

　　In this nursing home for the aged, there is also a "painter" nurse. Her name is Zhang Yuan.

　　"For most patients in our nursing home, healing and rehabilitation seem to be distant dreams, and their emotions are inevitably pessimistic and disappointed." Zhang Yuan picked up a childhood brush, and painting played a strange role here.

　　Grandpa Shi in the second ward is 86 years old, like an "old child". He especially likes to eat beef jerky, spiced beans and scallion cakes. He comes to everyone. The problem is that he has diabetes and can’t keep his mouth shut, which is going to cause trouble.

　　Once, on the birthday of Wang Apo in the next ward, several nurses bought a cake for the old man. Grandpa Shi looked at it, staring at the cake with his eyes fixed on it.

　　When the old man was young, he loved to eat commander Kay’s fresh milk cake. When he was old, he was sick and couldn’t eat it. Knowing this story, Zhang Yuan painted the old man’s favorite cake, colorful flowers, strawberries, cherries, yellow peaches and other fruits, and there was a bow next to the cake. I didn’t expect this to become a spiritual sustenance for the elderly! It turns out that the old man’s daughter now lives abroad, and the old man often ties a bow to his daughter’s braid when he is young.

　　"The old people who live in nursing homes are most looking forward to the companionship of their loved ones and the visits of their children." Zhang Yuan said. Li Nainai’s son is very busy at work. The old man doesn’t talk, but he often stares at his mobile phone. Zhang Yuan made two cards for her, one with a cartoon image of her son and the other with a photo of Li Nainai. When the old man received the card, he cried with joy and kept saying, "Like! Really like! " The old man put the card on the bed and said that he missed his son. Looking at the card gave him comfort and sustenance.

　　Grandpa Chen has lost his language function because of a cerebral infarction, and sometimes he is not conscious, but as long as his wife comes, he will try his best to support himself and see that their feelings are very good. But his wife is too old to come every day. Grandpa Chen often asks the nurse to call her, and then tries to get close to the receiver and listen to her voice.

　　The sincere feelings of the old people moved Zhang Yuan and her colleagues. Zhang Yuan specially posted a photo of the old couple on his painting, painted the appearance of the head nurse calling, and wrote "Hold your hand and grow old with your son".

　　During more than five years in Hudong Nursing Home, Zhang Yuan gave about 200 paintings to his grandparents. "Behind every painting, there is a story, a sustenance and a desire." She said so.

　　The problem of providing for the aged comes to the fore, and the "post-90 s" holds up everyone’s tomorrow

　　"Chaoyang" guards the "sunset", and such a warm-hearted picture is staged every day in Hudong Nursing Home for the Aged. This is not a microcosm of the social pension proposition.

　　Shao Guihua is 86 years old, and his wife, Xu Zhengtai, is 91 years old. Because of cerebral infarction, he is paralyzed and can’t take care of himself. In January 2016, the old man first lived in Hudong Senior Care Home.

　　As the saying goes, the golden nest and the silver nest are not as good as their own grass nest. When their wife is sick, she has to live in a nursing home. Shao Guihua has concerns. When she sees that most of them are post-90 s nurses, she even drums. "If not, go home."

　　What she didn’t expect was that it took only half a year from "trying to live" to "staying" and now "loving to live". She said that the sincere help of nurses made her feel at home, what’s more, she really couldn’t take care of it herself — — — She is also an old man who is running for nine.

　　"When the families of the patients we are facing are already old people, we know very well that the pace of an aging society is getting closer and closer." "How can 200 beds explore a better and more realistic pension model?" In Hudong Nursing Home for the Aged, the reporter heard such thoughts.

　　As the only public nursing institution for the aged in Yangpu District, Hudong Geriatric Nursing Home is currently exploring "2+1" (second-class hospital+first-class hospital), "combination of medical care and nursing" and other new nursing modes for the aged, including remote nursing and home-based care.

　　Everyone will grow old. In the future, it will not only be the "post-90s" but also the "post-90s" and "post-10th" who will take care of the elderly. Now, every post-90s is not only the sunset today, but also our hope for tomorrow. (Reporter Tang Wenjia)

CCTV News:As the summer movie file continues to heat up, cinemas around the country have also ushered in the peak of watching movies. I don’t know if you have noticed when buying movie tickets. Nowadays, there are different movie theaters to choose from, such as IMAX Hall, Dolby Panorama Hall, CINITY Hall and so on. Among them, CINITY, a domestic film screening system with China’s core independent intellectual property rights, has become the first choice for many viewers in this summer file.

In Shanghai CMG Media Studio, CINITY Cinema has become the first choice for many audiences to watch movies.

In Xinming Cinema in Chengdu, Sichuan Province, the first CINITY LED curved film screen in China, which was officially put into use at the beginning of this year, has been upgraded in summer by virtue of the 16-meter-wide curved CINITY LED film screen, the arc-shaped embracing design and the high-brightness and high-contrast image quality effect brought by LED self-luminous technology.　

State-owned independent brands help improve the film experience.

At present, CINITY and CINITY LED projection systems of China Film have been gradually recognized and favored by domestic and foreign film industries.So, what are CINITY and CINITY LED? What kind of scientific and technological power did they use to enhance the audience’s viewing experience? Get to know each other together.

CINITY system combines the high and new technologies of 4K, 3D, high brightness, high frame rate, high dynamic range, wide color gamut and immersive sound, which can not only present ultra-high resolution pictures, but also provide surround sound effect.

Wu Ting, manager of CMG Media Studio Management Department,Compared with the traditional 2D movie theater, the brightness of the film is 2 to 3 times higher, and at the same time, it can present more picture details, making the film look more delicate and richer. Through the extremely accurate positioning of the sound source and the changing process, the audience can accurately and clearly feel the changes in the sound location, frequency and sound size, and completely immerse themselves in the sound and scene story of the film.

CINITY LED curved film screen is the world’s first cinema LED projection system supporting 4K/120 frame high format.

In the early days of film development, the frame rate of film movies was 24 frames per second, that is, 24 pictures were played per second. However, with the development of technology, the emergence of digital movies has made people’s requirements for film frame rate have also improved. CINITY’s 4K/120 frame is also the highest frame rate version in the film and television field.

CINITY LED has adopted all domestic technical solutions and products, breaking the technical barriers in the industry. Its exclusive film plate-making technology ensures the full expression of the unique characteristics of LED projection to the greatest extent, which makes the film present clearer and smoother pictures and richer and more colorful colors, greatly enhancing the immersion of watching movies.

Up to now, CINITY and CINITY LED projection systems have reached 180 screens in China, and 12 systems have been installed in Europe and the United States.

The world’s first transparent LED giant screen appeared in Nanjing.

In May this year, the National Development and Reform Commission and other six ministries and commissions jointly issued the "Implementation Plan for Promoting Equipment Renewal in the Field of Culture and Tourism", pointing out that the large-scale implementation of the cinema LED display system renewal plan will provide viewers with more comfortable, convenient and rich film consumption services.

Not long ago, the world’s first "sound-transmitting LED giant screen" certified by DCI took the lead in a cinema in Nanjing, providing viewers with better film consumption services.

In the LED giant screen hall of a cinema in Nanjing, the documentary film "Earth Pulsation: Extreme Survival" is being shown.

This transparent LED movie screen is 20.48 meters wide and 10.8 meters high, supports 4K ultra-high definition resolution, and has a high refresh rate of 96 frames, which is four times that of the traditional projection screen. In addition, relying on the unique module perforation design of the product, the large screen puts the main channel audio back, and the sound cavity is realized through the structure of LED box.Ensure the sound transmission effect of the sound.

The upgrade of the screen has also brought a win-win situation for the cinema.

Domestic film projection systems are exported overseas.

At present, the domestic film projection system has broken the monopoly position of foreign countries on the core technology of digital movies.Not only in the domestic market, but also exported to overseas.

This screen showing movies is the HeyLED movie screen independently developed by China.

Chen Weijun, general manager of Shenzhen Times Huaying Technology Co., Ltd. introduced,Its brightness can reach 5 to 10 times that of the original projector, and the contrast ratio of ordinary movies is about 300: 1, but the LED can achieve more than 30,000: 1, so its black place is pure black, the bright place will be very bright, and the details of the bright and dark parts of the movie will be better restored.

This 10-meter-wide LED movie screen has more than 110 boxes, consisting of more than 2.3 million LED light beads, covering the entire light-emitting surface. When a movie is shown, according to the different brightness and color of the played image in different positions, some LED beads will be made to glow, and the rest of the LEDs will not glow at all, thus showing "white" and "black" close to the real world.

At present, HeyLED is not only widely used in cinemas in major cities in China, but also exported to the United States, the United Arab Emirates, Romania and other countries. This is the first time that China’s self-developed LED digital film projection system has been exported overseas.

From making brands to setting standards, the influence of China films has increased.

At present, China has become the country with the largest number of advanced LED film projection system manufacturers and cinemas. There are 18 manufacturers of global LED film projection system that have passed DCI certification, among which 13 are from China.

In addition, China has also actively participated in the formulation of international standards, from branding to setting standards, so that the influence of China’s film industry continues to increase.

In addition to continuous breakthroughs in independent research and development of projection technology, the first film ISO international standard "Technical Requirements and Measurement Methods for Stereoscopic Projection of Digital Cinema" led by China Academy of Film Science and Technology has been officially released recently.

The release of this international standard has filled the gap in China’s film international standard, and also enhanced the international discourse power of China’s film technical standard.

Dong Qiangguo, deputy director of China Film Science and Technology Research Institute, introduced that there is one (in the industry)unifiedGlobal internationalSpecification, "Technical Requirements and Measurement Methods for Stereoscopic Projection of Digital Cinema" is a global industry technical specification for the first time led by China, and it has also won the dominance for domestic film equipment to enter the international market and participate in international competition.
