(Reporter Wang Jingping, an intern in Zhang Yue, Li Tao) Recently, an article entitled "The Pinyin of these words has been changed" was screened on social media. In this regard, Liu Danqing, director of the Institute of Linguistics of the Chinese Academy of Social Sciences, replied to the Beijing Youth Daily reporter yesterday, saying that the pronunciation of Chinese characters mentioned in the online text, such as "Riding (qí) the world of mortals laughs" and "The accent has not changed (shuāi)", has not changed.

　　Netizens laughed at themselves for "going to a fake school"

　　On the 18th, an article entitled "The Pinyin of these words has been changed" was widely circulated on social media, which mentioned, "Because there are many people who mispronounce, ‘ The local accent has not changed, and the hair on the temples has declined (shuāi)’ ‘ Far from Hanshan, the stone path is inclined (xié)’ ‘ Ride (qí) the princess of the world of mortals and laugh ’ The pronunciation in ancient poems has changed. " Some netizens said that the pronunciations of ancient poetry and prose all rhyme. After such changes, ancient poetry and prose lost their original rhyme.

　　Yesterday afternoon, Liu Danqing, director of the Institute of Linguistics, Chinese Academy of Social Sciences, who compiled and revised Modern Chinese Dictionary and Xinhua Dictionary, replied to the reporter of Beiqing Daily that the pronunciations of Chinese characters such as "riding on the world of mortals (qí) and" shuāi "mentioned in this website have not changed, among which" riding on the world of mortals (qí) and smiling on the princess "have not changed. As for "hair decline on the temples", "decline" has always had the pronunciation of (cu Ρ), which is two special meanings in ancient times. The Modern Chinese Dictionary still retains this pronunciation at present.

　　Is there any change in the pronunciation of Chinese characters?

　　So is there any change in the pronunciation of Chinese characters? Liu Danqing introduced that the previous phonetic examination was mainly based on the Beijing phonetic system, and the new phonetic examination principle fully considered the development trend of Beijing language, but also properly referred to the degree of communication in Mandarin and other dialect areas. In Beijing dialect, the word "Jing" originally has different pronunciations in the vernacular, with a literal pronunciation of gēng and a vernacular pronunciation of jīng. According to the phonetic development trend of Beijing dialect, the vernacular pronunciation of "Jing" is dying out, while the vernacular pronunciation is more corresponding to other dialects in China, which is more convenient for learning Putonghua. Therefore, the pronunciation of "Jing" is revised from the vernacular pronunciation to the vernacular pronunciation.

　　In addition, it is mentioned in the net that the word "Shuo" in the two words that were originally read as "Shuo (Shu) Ke" and "Shuo (Shu) Fu" was changed to "Shu not".

　　The reporter of Beiqing Daily noticed that in the latest edition of Modern Chinese Dictionary in 2016, the word "Shuo" in "lobbyist" was pronounced as "(shuō)", but in the latest revised opinion draft of Auditory Table, this word was changed to "Shuo (shuō) ke". In fact, "persuasion" has always been pronounced as "shuō", and there is no pronunciation of "shuō".

　　Pronunciation of ancient poetry should be respected.

　　Another focus of this controversy lies in the pronunciation of Chinese characters in ancient poetry. Meng Pengsheng, a researcher at the Institute of Linguistics, Chinese Academy of Social Sciences, who participated in the development of the new version of the Auditory Table, mentioned, "‘ Riding a princess in the world of mortals and laughing ’ Zhong ‘ Ride ’ Ancient reading when words were used as nouns or quantifiers ‘ jì’ , followed by ‘ Ride (qí)’ The meaning and usage are different, ‘ Riding a princess in the world of mortals and laughing ’ ‘ Ride ’ The word is just in the position of the word. However, there is no such difference in spoken Mandarin today, so the old version and the new version of the Auditory Table have stipulated that ‘ Ride ’ Read as ‘ qí’ 。” Meng Pengsheng believes that, as a national norm, the Auditory Table is applicable to all occasions, and naturally it is also applicable to ancient poems. In principle, reference books and textbooks for primary and secondary school students should not be marked with real "ancient sounds" and so-called "ancient sounds", but the use of some "ancient sounds" in some special occasions, such as ancient poetry recitation activities and other literary forms, should be respected and tolerated, just like the "catchy words" in Beijing opera art.

　　How do you pronounce these words?

　　◎ Japonica J χ ng rice is to be changed into Japonica gēng rice.

　　◎ Bleeding xuè is going to be changed to reading the written language in a unified way.

　　◎ Ride a princess in the world of mortals and laugh.

　　◎ Far from Hanshan, the stone path is inclined (xié)

　　◎ The local accent has not changed its hair (shuāi, also read cu:)

　　◎ Say (shuì) guest.

　　◎ Say (shuō not) take.

　　Have you searched the Internet for "What hurts me? Is there something wrong with me?"? The answer may not be satisfactory. However, with the emergence of large-scale natural language models (LLM) such as ChatGPT, people began to try to use it to answer medical questions or medical knowledge.

　　However, is it reliable?

　　As far as it is concerned, the answer given by artificial intelligence (AI) is accurate. However, James Davenport, a professor in university of bath, pointed out the difference between medical questions and actual medical practice. He believed that "medical practice is not just about answering medical questions. If we just answer medical questions, we don’t need to teach hospitals, and doctors don’t need to receive years of training after academic courses."

　　In view of all kinds of doubts, in a recent paper published by Nature, the world’s top artificial intelligence experts showed a benchmark to evaluate how well large-scale natural language models can solve people’s medical problems.

　　The existing model is not perfect.

　　The latest assessment comes from Google Research and Deep Thinking. Experts believe that the artificial intelligence model has many potentials in the medical field, including knowledge retrieval and supporting clinical decision-making. However, the existing model is not perfect, for example, it may fabricate convincing medical error information, or include prejudice to aggravate health inequality. Therefore, it is necessary to evaluate their clinical knowledge.

　　Relevant assessments have not been without before. However, in the past, it usually relied on automated evaluation of limited benchmarks, such as individual medical test scores. This is translated into the real world, and both reliability and value are lacking.

　　Moreover, when people turn to the Internet to obtain medical information, they will encounter "information overload" and then choose the worst one from 10 possible diagnoses, thus bearing a lot of unnecessary pressure.

　　The research team hopes that the language model can provide short expert opinions, be unbiased, indicate its citation source, and reasonably express uncertainty.

　　What is the LLM performance of 540 billion parameters?

　　In order to evaluate the ability of LLM to encode clinical knowledge, Xie Kufei Aziz, an expert from Google Research Institute, and his colleagues discussed their ability to answer medical questions. The team put forward a benchmark called "MultiMedQA QA": it combines six existing question-answering data sets covering professional medical care, research and consumer inquiries and "HealthSearch QA" & mdash; — This is a new data set, which contains 3173 medical questions searched online.

　　The team then evaluated PaLM (a 540 billion parameter LLM) and its variant Flan-PaLM. They found that Flan-PaLM reached the most advanced level in some data sets. Flan-PaLM surpassed the most advanced LLM by 17% in the MedQA data set integrating the questions of American medical license examination.

　　However, although Flan-PaLM scored well in multiple-choice questions, further evaluation shows that it has a gap in answering consumers’ medical questions.

　　LLM of specialized medicine is encouraging.

　　In order to solve this problem, artificial intelligence experts use a method called design instruction fine-tuning to further debug Flan-PaLM to adapt to the medical field. At the same time, the researcher introduced an LLM— — Med-PaLM。

　　Fine-tuning design instructions is an effective way to make general LLM suitable for new professional fields. The resulting model Med-PaLM is encouraging in the trial evaluation. For example, Flan-PaLM scored by a group of doctors is only 61.9% consistent with the scientific consensus, and Med-PaLM scored 92.6%, which is equivalent to the answers made by doctors (92.9%). Similarly, 29.7% of Flan-PaLM’s answers were rated as likely to lead to harmful results, and only 5.8% of Med-PaLM’s answers were equivalent to those of doctors (6.5%).

　　The research team mentioned that although the results are promising, it is necessary to make further evaluation, especially in terms of safety, fairness and prejudice.

　　In other words, there are still many limitations to overcome before the clinical application of LLM is feasible.

　　Xinhua News Agency, Tianjin, June 28th-China has been an active advocate and practitioner of South-South cooperation for more than 70 years. Many people who are attending the 14th Summer Davos Forum in Tianjin, China said that China is playing an increasingly important role in global South-South cooperation with its accumulated experience, technology and talent advantages in agricultural technology popularization, global poverty reduction and public health, providing a "China sample" for reference.

　　China agricultural technology drives bumper harvest.

　　To achieve the goal of global hunger eradication, Africa is an important puzzle. The food supply here is seriously threatened by climate change and land desertification, and the agricultural technology in China has provided important help for increasing local food production and improving food security.

　　In Mozambique, Wanbao Mosang Agricultural Park, which china-africa development fund participated in, is a large-scale rice planting project, which has significantly improved the local rice planting and rice processing technology; In Kenya, the field micro-rainwater harvesting technology from China was applied in the local demonstration area to grow corn, and the yield increased by 99% to 240%. In Burundi, the expert group of China selected and introduced eight kinds of rice suitable for the local area, which solved the historical problem that the local mountainous area often lost production or even failed to harvest due to rice blast.

　　China has built a number of agricultural technology demonstration centers in Africa, and projects such as "Demonstration Project of Increasing Corn Yield by Thousands of Households and Ten Thousand Mu" have blossomed locally.

　　In the eyes of South African delegate Malelai, China’s agricultural technology has brought tangible benefits in agricultural innovation, poverty alleviation and food security. He said that he expected more cooperation between Africa and China in food security and mitigation of the impact of climate change.

　　According to the data of the Ministry of Agriculture and Rural Affairs of China, by 2021, China has sent more than 2,000 agricultural experts and technicians to more than 70 countries and regions, and promoted and demonstrated more than 1,500 agricultural technologies to many countries, driving the project to increase production by 40% to 70% on average.

　　Medical and health experience in China promotes health.

　　This year marks the 60th anniversary of the dispatch of China’s foreign aid medical team. Over the past 60 years, China has sent 30,000 medical personnel to 76 countries and regions around the world, treating 290 million patients.

　　China, together with its partners in developing countries, shared the experience gained in the field of public health in China, shared public health products such as vaccines, and made joint efforts to reduce the disease burden in developing countries and promote global health governance.

　　The global malaria burden is mainly concentrated in southern countries. There were still 30 million malaria cases in China from the early days of the founding of the People’s Republic of China. By 2017, the number of local malaria cases was reported to be zero, and by 2021, it was certified by the World Health Organization as the national malaria elimination certification … … China’s achievements in malaria control provide a reference for overcoming malaria problems and promoting global health.

　　In Tanzania, using China’s barefoot doctor model for reference, villagers were recruited and trained to become the core medical staff or volunteers of local medical teams. Learn the work standard of "1-3-7" malaria case report and detection in China, that is, complete the case report within 1 day, complete the case review and epidemiological investigation within 3 days, and carry out the investigation and disposal of epidemic spots within 7 days; Pipequine dihydroartemisinin phosphate tablets produced in China have also been popularized in pilot areas.

　　Ren Minghui, a professor at Peking University School of Public Health and former assistant director-general of the World Health Organization, said in an interview with Xinhua News Agency during the forum that South-South cooperation in China is open, inclusive and oriented to the needs of South-South countries. Whether China’s anti-malaria technical scheme has been promoted by WHO for many times, or China’s aid to build medical infrastructure and China’s pharmaceutical enterprises’ overseas localized production or technology transfer, China has provided a reference, further localized and concrete scheme for southern countries to strengthen health system construction.

　　China’s program helps to meet global challenges.

　　At present, international geopolitical conflicts have intensified, North-South cooperation has slowed down, and the development gap has widened, thus facing many challenges in achieving the goal of sustainable development in 2030. According to United Nations statistics, there are still more than 800 million people starving and 350 million people in need of humanitarian assistance in the world, and the momentum of implementing the sustainable development goals has obviously slowed down.

　　China, with its own development path, has provided the world with a feasible and reproducible reference, and also contributed China’s plan and China’s wisdom to jointly deal with global challenges.

　　Zhang Jianping, deputy director of the Academic Committee of the Institute of International Trade and Economic Cooperation of the Ministry of Commerce, said that China has set a development model for the southern countries. China’s participation in South-South cooperation does not attach political conditions and requirements like western countries, which provides opportunities for southern countries to improve their own capacity building, development level and development efficiency.

　　Eliminating poverty is a common challenge facing mankind. As the country with the largest poverty reduction population in the world, China has contributed more than 70% to global poverty reduction, creating a miracle in the history of poverty reduction in the world. Poverty reduction in China has become a research sample of more and more countries and international organizations.

　　Facing the challenge of global climate change, in 2015, China set up the China South-South Cooperation Fund on Climate Change with 20 billion yuan; Since 2016, China has launched 10 low-carbon demonstration zones, 100 climate change mitigation and adaptation projects, and 1,000 cooperation projects to cope with climate change training places in developing countries, and implemented more than 200 foreign aid projects to cope with climate change.

　　Zhu Min, vice chairman of China International Economic Exchange Center, told Xinhua that China has accumulated experience and technology in carbon neutral macro management, technological innovation and new industrial layout. At present, China’s photovoltaic manufacturing industry accounts for 90% of the global production capacity and is an important source country of global wind power equipment and electric vehicles. "China has great potential to promote the green transformation of developing countries in terms of carbon neutrality."

　　Sri Lankan Foreign Minister Sabri said that Sri Lanka’s economy has achieved remarkable growth since China invested in the local area and started infrastructure construction. South-South cooperation is an important mechanism to jointly promote the solution of global challenges, in which China plays an important role.

　　The "China sample" of South-South cooperation provides enlightenment and reference for developing countries from the perspective of global development. In the long run, more global governance has explored new models and new paths different from those in the West. (Reporter Zhang Miao, Xu Supei, Bai Jiali, Henry Hui Wang, Zhang Yuqi)

　　Covid-19 came back with a comeback. With the increase of the number of "Eryang", some people began to worry that multiple infections would cause the virus to accumulate in the body, resulting in the superposition of symptoms. There are even rumors that people can be infected up to eight times, and more will die. The latest issue of the scientific gossip list was released, which refuted the above statement. In addition, more health rumors have been "concentrated" this time.

　　The monthly "scientific" gossip list is guided by Beijing Science and Technology Association, Beijing Municipal Committee Network Information Office, Capital Internet Association, and jointly released by Beijing Science and Technology Journalists Editors Association and Beijing regional website joint rumor platform.

　　It is rumored that blood tests will reduce human immunity.

　　The truth network will draw blood away the white blood cells with immune function, and also remove substances, electrolytes, vitamins and so on that are important to the body. Even mistaken for the more serious a person is, the more blood tests will be taken, which makes many people stay in bed and even die prematurely.

　　In fact, drawing blood won’t hurt you. Generally, the amount of blood for blood test will not exceed 20 ml, while the average human body has 4000 ml of blood, and it has the function of automatic regeneration. Pumping a small amount of blood will not affect human health.

　　Although the main cells that constitute human immunity are white blood cells, the proportion of red blood cells in the blood is large, while the number of white blood cells is small. Generally, donating 200 ~ 400 ml of blood will lose 1% ~ 2% of the total number of human white blood cells, and within 1 ~ 2 hours after blood drawing, the lost white blood cells will return to their original number. Therefore, many white blood cells will not be lost after blood drawing, and the immunity will not be reduced.

　　It is rumored that asthma patients will "gasp"

　　The truth is that it must not be asthma without wheezing symptoms? For asthma, many people still stay in the performance of "shortness of breath and difficulty breathing" in movies and TV series. In fact, these are just typical manifestations of acute asthma attacks. When patients encounter cold air and dry air, they are prone to asthma attacks. The typical symptom of asthma is recurrent wheezing, which may be accompanied by shortness of breath, chest tightness or cough.

　　However, there are still many atypical asthma in clinic. Cough variant asthma, cough is its only or main clinical manifestation; Chest tightness variant asthma, with chest tightness as the only or main symptom; Concealed asthma does not have the typical symptoms of recurrent wheezing, shortness of breath, chest tightness or cough, but it has long-term increased airway responsiveness.

　　It is rumored that drinking lemonade will lead to stones.

　　There are many causes of truth stone, among which heredity, metabolism, anatomical structure and diet are the main factors, among which diet is the most concerned. From the composition point of view, calcium oxalate is the main stone in the body, and a large amount of oxalic acid in the diet intensifies the formation of stones to a certain extent. For example, the oxalic acid content in vegetables such as spinach, celery and leek is high, but it does not include lemon.

　　Unlike oxalic acid, which forms insoluble substances when it meets calcium, calcium citrate tetrahydrate formed by combining citric acid rich in lemon with calcium is slightly soluble in water. At the same time, the slight acidity of citric acid in the intestine can also promote the absorption of calcium, iron, zinc and other mineral elements, which is beneficial to health.

　　The myth that "water control by hanging upside down" can save drowning people.

　　There is a "classic" picture of rescuing drowning people circulating on the truth network — — The rescuer mentioned that the drowning man’s feet were shaking upside down, or ran backwards with the drowning man’s back, trying to "control" the water in the drowning man’s body before cardiopulmonary resuscitation.

　　However, this way, which is considered to have a higher success rate, is not desirable.

　　To rescue drowning, we should remember "four things without doing one thing". "Don’t do it" means that the drowning person will not control the water after being rescued ashore. The method of running around with drowning children on their backs on the Internet is absolutely wrong. It is impossible to expel water from the body, and it may also make the food in the drowning person’s stomach flow backwards, which will aggravate the difficulty in breathing. Hanging upside down to control water can not replenish oxygen in the blood of drowning people, and most of the water controlled is water in esophagus and stomach. For the drowning person who has already had cardiac arrest, cardiopulmonary resuscitation should be started as early as possible to save the patient.

　　"Four actions" are the four correct steps to deal with the drowning person: First, immediately rescue the drowning person from the water and quickly judge whether breathing or heartbeat stops. Second, call the emergency number 120 and get the AED nearby. Third, for those whose breathing and heartbeat have stopped, cardiopulmonary resuscitation should be carried out immediately according to ABC (open airway — Blow — Press) of the recovery operation sequence. If there is no breathing and heartbeat, just blow (12 ~ 16 times per minute) without chest compressions. Fourth, if there is trauma, deal with it in time, especially head and neck injuries.

　　Rumor has infected COVID-19 eight times at most.

　　Truth With the recurrence of the COVID-19 epidemic, a saying appeared on the Internet that "no matter how healthy and strong a person is, he can only be infected with COVID-19 for 8 times at most, and the person will be gone after the 9th time". The truth is, it is possible for a person to repeatedly infect COVID-19. However, for people who have no basic diseases, the statement that "they can only be infected for 8 times at most" is unscientific, and the symptoms are generally mild after reinfection.

　　At present, the observation and research all show that the symptoms of COVID-19 will become lighter and lighter after reinfection. After the first infection, the body produces immunity to pathogens. Even with the passage of time, the specific immunity level against this pathogen gradually declines. After the second infection, the body can quickly enhance the immunity level again through the recall reaction, killing the pathogens in the body. Therefore, the symptoms will not get worse after repeated infection.

　　In addition, in the process of spreading and spreading, pathogens usually mutate in the direction of gradually weakening pathogenicity and gradually enhancing infection ability.

　　If you are really worried about the problem of repeated infection, people over 60 years old and people with basic diseases can be vaccinated with vaccines and booster shots. Go to crowded places, especially hospitals, try to wear masks all the time, and wash your hands and disinfect them when you get home.

　　Rumor may require hysterectomy to solve dysmenorrhea.

　　Truth Recently, patients with network-transmitted adenomyosis can solve the problems of dysmenorrhea and anemia by hysterectomy. However, the treatment of adenomyosis depends on the severity of symptoms, age and fertility requirements.

　　Generally speaking, doctors will use drugs to relieve the disease first, and if the drugs can’t relieve it and there are fertility requirements, doctors will remove the lesions. Total hysterectomy will only be considered if the symptoms are particularly serious, there is no fertility requirement and medical treatment is ineffective.

　　The data show that 35% of patients with adenomyosis are asymptomatic, but 40%-50% are characterized by excessive bleeding during menstrual cycle, and 15%-30% will be characterized by dysmenorrhea. The treatment of adenomyosis depends on the severity of symptoms, age, and fertility requirements.

　　There are four basic requirements of medical ethics: first, the interests of patients are paramount; Second, respect the patient’s right to choose independently; Third, do not hurt; Fourth, the fairness and justice of medical resources. The third point "no harm" means that if the patient’s uterus has no indication of resection, the doctor will never remove it. If the doctor is removed without indication, then the doctor violates the principle of medical ethics and the provisions of the Physician Law, and will be severely punished.

　　Whether the myth is obese depends on the weight

　　The truth is that as long as you are not overweight, you are not obese? No, obesity needs to consider multiple "technical parameters"!

　　To measure whether a person is obese, the commonly used standard is "Body Mass Index" (BMI). It is obtained by dividing a person’s weight (kg) by the square of his height (m). If this value is between 18.5 and 23.9, it is normal weight, and if it exceeds it, it is obese.

　　In addition, whether obesity depends not only on weight, but also on body fat rate. The ratio between total body fat and body weight is called "body fat rate". Generally, the body fat rate of healthy young men does not exceed 20%, and that of women does not exceed 30%. If it exceeds this value, even if the weight is standard, it is the body fat exceeding the standard.

　　On the basis of weight and body fat percentage, there is also a very important value "waist-hip ratio", which is the ratio between waist circumference and hip circumference. If the waist-hip ratio of men is greater than 0.85 and that of women is greater than 0.8, then even if the weight is normal, it may belong to excess abdominal fat accumulation, or even reach "abdominal obesity", which will bring greater potential harm to the body.

　　Rumor has it that sleeping on a hard bed can cure lumbar spondylosis.

　　Truth Jianghu legend says that "people suffering from lumbar pain had better choose a hard bed to sleep, which can cure diseases". However, this is a misunderstanding. Many people think that "hard bed" refers to hard bed and smooth bed. In fact, the hard bed is relative to the soft mattress that Europeans and Americans are used to. The hard bed does not mean a hard bed, let alone a smooth bed, and there are several mattresses on it.

　　Expert introduction: There are four physiological curvatures in the normal spinal structure of human body, namely, cervical curvature, thoracic curvature, lumbar curvature and sacral curvature. If the mattress is too soft, it cannot provide proper spinal support; If the mattress is too hard, it will rely too much on shoulder and hip support, which will also cause spinal distortion; The middle soft bed (hard bed) can better adapt to the curve of human body, and the spine is the least twisted.

　　So, how to grasp the hardness of the mattress on the bed board? Remember the "3: 1 principle", that is, the mattress should not be so hard as not to deform, nor should it deform too much. A 3 cm thick mattress sinks 1 cm when pressed by hand, and a 10 cm thick mattress sinks 3 cm, so the ratio is moderate.

　　Then, lie flat on the mattress, reach out and touch the neck, waist and buttocks to thighs to see if there are any gaps. Then turn the body to one side and try to see if there is a gap between the concave part of the body curve and the mattress in the same way. If the hand can be easily inserted in the gap, it means that the bed is too hard; If the palm of your hand clings to the gap, it proves that the mattress fits the curve of the human body.

　　In addition, when choosing a mattress, we need to refer to three factors besides hardness and fit: gender, weight and age. Women are suitable for elastic mattresses, while men are relatively hard; Slim figure is suitable for a slightly soft mattress, and obese people should sleep on a harder mattress; Infants should choose a moderately soft mattress, while children and teenagers should not sleep on a soft mattress to avoid affecting their growth and development; Elderly people with loose ligaments, especially those with osteoporosis, are advised to choose a slightly hard mattress.

　　Of course, relieving low back pain is not a very simple thing. Don’t imagine that changing a bed or a mattress can completely solve it. Daily maintenance and rehabilitation exercise, avoiding excessive use of lumbar vertebrae and actively coping with problems are all important links to relieve low back pain.

According to the data released by the National Film Bureau on February 18th, the box office of Chinese Spring Festival movies in 2024 reached 8.016 billion yuan, setting a new box office record for the Spring Festival movies, with 163 million people watching movies.

From YOLO’s Pegasus 2, which tells an inspirational life story, to Article 20, which shows the power of fairness and justice, to Boonie Bears: Time Twist &hellip, which shows childlike innocence; … This year’s Spring Festival movies are mainly provided by comedy types and animated films, which will drive the audience into the cinema to celebrate the New Year and promote the sustained recovery of China’s film market.

[Get eye-catching box office results]

This year’s Spring Festival holiday is slightly longer than in previous years, the film supply is abundant, the audience’s demand for watching movies has been fully released, and the box office and the number of people watching movies have reached new highs.

Specific to a single film, YOLO led the box office with 2.718 billion yuan, and the box office of Pegasus 2 also exceeded 2 billion yuan. Boonie Bears: Time Twist and Article 20 ranked third and fourth respectively in the box office list.

According to the survey of China movie audience satisfaction released by China Film Archive, the audience satisfaction score of this year’s Spring Festival stalls is 85.9, ranking second among the nine Spring Festival stalls surveyed since 2015.

"The Spring Festival movies reflect the creative concept of going deep into life and taking root in the people. The creators turn their eyes to the grand narrative and pay more attention to the life experiences and growth process of ordinary people." Zhifina, a professor at the China Academy of Art, believes that these films focus on realistic themes, echo the audience’s expectations for film works, and push the box office to continue to rise.

In terms of the audience, Chen Jin, a data analyst of Lighthouse Professional Edition, said that the box office share of third-and fourth-tier cities increased significantly this year compared with last year, and the number of family audiences increased significantly. "It can be said that the Spring Festival is still a significant’ sinking’ schedule, which will help to better stimulate the vitality of relevant markets." Chen Jin said.

In addition, relevant data show that the average ticket price of this year’s Spring Festival stalls has dropped significantly compared with last year. Under the guidance of Publicity Department of the Communist Party of China Film Bureau and relevant departments of China People’s Bank, 11 financial institutions, including China Industrial and Commercial Bank, China Agricultural Bank and China Construction Bank, invested more than 30 million yuan in subsidies for movie viewing during the Spring Festival. Through full reduction, coupons, digital red envelopes and other means, the audience’s movie consumption gained tangible benefits.

[Comedy films are in full supply]

Throughout the Spring Festival in recent ten years, the head film is often supported by comedy, and whoever can lead the family fun will win the market. This year’s Spring Festival file is an out-and-out "all-staff comedy" Spring Festival file.

"Comedy elements cover almost all the new films released, and the audience laughs often and tears come from it." Li Xiaojun, vice chairman and secretary general of the Shanghai Film Association, analyzed that YOLO advocated living the "true self"; Pegasus 2 encourages people to stick to their dreams in middle age; "Article 20" profoundly reveals the emotion and temperature behind the legal provisions with comedy as the carrier, and the film focuses on the issues that people are concerned about at present, which is impressive.

According to the satisfaction survey of movie audiences in China, YOLO’s main actors’ performances, the visual effects of Pegasus 2 and the positive energy of Article 20 have all been well received by ordinary audiences.

The audience also noticed that "The Movie Emperor", directed by Ning Hao and starring Andy Lau, reflected on all kinds of oddities in the current entertainment field in a humorous way. "Viva La Vida" also chooses to explore the contemporary youth’s outlook on life in a relaxed and humorous way, and the whole film is permeated with an optimistic attitude towards life.

Rao Shuguang, president of the China Film Critics Association, believes that comedy movies are just needed for the Spring Festival. During the Spring Festival, most of the audience walked into the cinema with a relaxed attitude, in order to "have fun." This year, we can see many comedies with thoughts and feelings appearing in the Spring Festival stalls, which brings confidence to the whole industry and is full of positive energy in the Spring Festival.

"Comedy movies can also make people cry. This reflects the kind of responsibility deeply rooted in the times when domestic films develop to a certain height. " Li Xiaojun said.

[Outstanding performance of animated films]

The outstanding performance of "Boonie Bears: Time Twist" in this year’s Spring Festival has attracted a lot of attention. On the first day of the film’s schedule, the box office score exceeded 200 million yuan, and the box office score reached 1.389 billion yuan in the final schedule.

"Boonie Bears: Time Twist" is the tenth film in the series of "Bears Come and Go". The creative team made further innovations in narrative and pictures, telling the story of Logger Vick who came to the metropolis to start his life again. In order to save Xiong Da Xiong Er, he started an adventure journey through time and space, which was close to daily life and integrated with animation, comedy, science fiction and other elements.

As "frequent visitors" in the Spring Festival, the box office performance of the "Bear Haunted" series movies has been rising steadily, which is not only due to the parent-child audience base accumulated over the years and the habit of watching movies during the Spring Festival, but also closely related to the continuous pursuit of breakthroughs in film creation.

According to the analysis of relevant experts, with the increase of the age of the audience, the "bears haunt" has also been "growing up", breaking the boundaries of young age and gradually becoming more compatible in content, and trying to explore deeper topics by enriching narrative connotations and attracting audiences of different ages.

In fact, looking at the domestic animated films in recent years, from Ne Zha, to The New God List: Yang Jian, and then to Chang ‘an Three Wan Li, the creators of animated films have been actively exploring the content and expression, which has improved the technical techniques, narrative level and expression of domestic animated films, and also reflected the continuous development of China’s film industry.

In addition, The Lower Bound of Pig’s Tent, which tells the story of Pig’s growth, and Huang Qi: The Cat of the God of Wealth, which combines the festive elements such as the God of Wealth and the cash cow, also appeared on the big screen during the Spring Festival. The film draws nourishment from the excellent Chinese traditional culture, which sets off a jubilant movie-watching atmosphere and provides more choices for family movie-watching groups.

　　CCTV News: Li Bin, male, born in May, 1950, Han nationality, party member of CPC, section chief of Shanghai Electric Hydraulic Pneumatic Co., Ltd.

　　Li Bin has successively completed 55 new product development projects, 201 process research projects, more than 1,500 NC machining process programming projects, directly created economic benefits of more than 8.3 million yuan, designed 184 cutters, and made 82 pairs of self-made improved fixtures and fixtures, which saved high costs for enterprises and won many patents.

　　Honors won: second prize of national scientific and technological progress, four consecutive national model workers, Chinese skill award, top ten national models of high-skilled talents, Shanghai Mayor’s quality award, and the first Shanghai craftsman.

　　I. Resume

　　Li Bin, male, born in 1960, graduated from technical school in 1980 and entered Shanghai Hydraulic Pump Factory as a junior worker. In order to better contribute to the development of the enterprise, he aims at the continuous charging of demand, what is missing in the post, what he studies, and what the enterprise needs, he will make up. Through self-study, he completed his high school studies. After three years of spare-time study, he obtained a junior college degree in mechanical engineering from Shanghai TV University. In the summer of 1998, Li Bin obtained a bachelor’s degree in mechanical and electronic engineering from shanghai second polytechnic university, and obtained a bachelor’s certificate and a bachelor’s degree.

　　Li Bin is now the section chief of the CNC workshop of Shanghai Electric Hydraulic Pneumatic Co., Ltd., a senior engineer, a senior technician, a chief technician of Shanghai Electric (Group) Corporation, and one of the most influential labor models since the founding of New China. He has won the first top ten workers’ inventors in Shanghai, outstanding professional and technical talents in Shanghai, Chinese Skills Award, national knowledge worker model, national top ten high-skilled talents model, and enjoyed the special allowance of the State Council experts; In 2011, he won the first prize of national model individual and expert in technological innovation of machinery industry workers and outstanding technological innovation achievements of Shanghai workers; In 2013, he was recognized as the chief gold medal worker of the national mechanical metallurgy building materials system. Li Bin is a representative of the 11th, 12th and 13th National People’s Congress and the 16th, 17th and 19th National People’s Congress of the Communist Party of China (CPC). Delegate to the 13th, 14th, 15th and 16th National Congresses of the All-China Federation of Trade Unions. Shanghai Electric Group established the first school named after ordinary workers in China — — Shanghai Electric Li Bin Technician College. Under the background of "innovation-driven, transformational development", Li Bin used his actions to change the status quo that China’s hydraulic technology is still at a low level in the world, and the basic parts of high-end construction machinery and equipment are completely dependent on imports.

　　Second, the work performance

　　1. Personal moral integrity

　　A tree is a painting, and a forest is a landscape. Li Bin always believes that no matter how great one’s personal skills are, it is only a single strength. Only by cultivating and bringing out more "smart workers" can we effectively promote enterprise development and social development.

　　Through Li Bin Studio as the carrier, Li Bin trained and trained a group of technical backbones who love the enterprise, love their jobs, have dedication, can study hard and work hard. Through the training of key projects, many studio members have made outstanding achievements in their jobs.

　　2. Excellent professional ability

　　Since 2012, Li Bin has led the members of the studio and made many breakthroughs in the localization project of A6V variable motor:

　　2.1 A6V series of new product development projects

　　The project has completed seven series, including A6V28, A6V55, A6V80, A6V107, A6V160, A6V200 and A6V250, including new product development and small batch production, and the performance of the products has basically reached the level of similar products of Rexroth.

　　2.2 A6V series cylinder measurement key project

　　According to the characteristics of NC machine tool processing and the measuring principle of three-coordinate measuring instrument, a set of simple and practical coaxiality measuring die is designed.

　　This measurement method is simple and reliable. Now this spherical measuring mold has been manufactured and put into use. The coaxiality between the axis of the seven holes in the cylinder body and the spherical surface can be controlled within 0.02 mm. The quality of the cylinder body is greatly improved.

　　2.3 Manufacturing Project of Assembly Line of Inclined Shaft Piston Pump

　　Through the analysis of the upper and lower stations and fixture positioning, the project organized the improvement of the assembly line. After the trial assembly of the products, the assembly line was gradually improved, which achieved obvious improvement effects: through the active participation and cooperation of various departments, the design and manufacture of the assembly line of the inclined shaft piston pump were completed, and the quality and efficiency of production were greatly improved.

　　2.4 Design and application of casting mould for motor cover and shell of variable speed motor

　　The purpose of the project is to solve the problems of looseness and sand holes in the casting of the motor cover and shell of variable speed motor.

　　According to the characteristics of the product, the casting mold was redesigned and made. The metal mold was used for assembly line casting, and the whole casting process and various parameters were controlled by computer. It plays a very important role in improving product quality and reducing scrap rate.

　　Through a series of project innovations, such as A6V series new product development project, A6V series cylinder measurement tackling key problems project, inclined shaft piston pump assembly line manufacturing project and variable motor motor cover and shell casting mold design and application project, A6V series inclined shaft hydraulic variable motor has reached the international advanced and domestic leading level.

　　3. Outstanding work performance

　　High-pressure axial piston pump/motor is an important component of hydraulic system. The low level of basic technology in China leads to the domestic hydraulic technical performance and reliability far behind that in Germany, which has become a bottleneck restricting the development of main engine. The development of domestic high-end construction machinery mainframe industry depends entirely on imported hydraulic components, and the national military products are also greatly affected.

　　In order to revitalize the hydraulic technology in China, Li Bin took the initiative to propose and undertake the innovative research project of "Key Technologies for Localization of High-pressure Axial Piston Pump/Motor", with the goal of increasing the maximum pressure from 25MPa to 40MPa and the maximum rotation speed from 1,500 r/min to 6,000 r/min, so as to meet the performance requirements of high-end hosts. He led the project team, and through the design and application of 11 technological innovations, laid the foundation for the key technical indicators of the products to reach the international advanced level. Through the third-party type test, the main technical indicators have completely reached the German peak pressure and the highest speed. The appraisal conclusion of Shanghai Economic and Information Commission on "Key Technologies of Localization of High-pressure Axial Piston Pump/Motor" is: "The project has reached the domestic leading and international advanced level in general." The project won the second prize of National Science and Technology Progress Award and the first prize of China Machinery Industry Science and Technology Award.

　　In recent years, Li Bin led the team to make a breakthrough in the project of high-pressure axial piston pump/motor, and further developed the more advanced A6V series variable motor domestically. A6V series oblique-shaft hydraulic variable-speed motors are widely used in the construction machinery industry at present, for example, they can be used to hoist and rotate crawler cranes, and they are important basic parts of construction machinery. However, A6V series inclined-axis hydraulic variable-speed motors used in China’s construction machinery industry have long relied on imports and are basically monopolized by international giants in Europe and America.

　　Due to some domestic fields, such as metal materials, heat treatment technology of metal materials, high precision and high precision machining technology, there is still a certain gap compared with the international advanced level. The A6V products produced by us have many problems, such as many early failures, unstable processing quality and low qualified rate of parts processing. In order to change these technical problems of A6V products, Li Bin Studio took A6V product technical research as "Model Worker Innovation Studio Project". After the completion of the project, the annual sales revenue of variable displacement pump/motor series products related to this key project exceeded 6 million yuan.

　　The breakthrough of key technologies has enabled China to truly possess the internationally advanced manufacturing technology of variable speed motors. By tackling the key problems of localization, we truly have the international advanced manufacturing technology of hydraulic components, which has practical and long-term significance for changing the backward situation of basic hydraulic components in China.

　　Third, the economic and social benefits achieved

　　1. Economic benefits

　　In 2015 and 2016, due to the influence of macro-control, the construction machinery industry was not prosperous, and the sales of major domestic main engine plants all dropped significantly, but our variable displacement pump/motor products still achieved sales of 7.57 million yuan and 6.14 million yuan respectively. Since the end of 2016, with the gradual deepening of the national "One Belt, One Road" strategy, the construction machinery industry has gradually stepped out of the trough. Especially since January 2017, the supply of hydraulic pumps/motors produced by our company has been in short supply in the construction machinery market in China, and the sales volume has greatly increased compared with previous years. In 2017, the sales volume of products related to key projects was 9.213 million yuan, which achieved good economic benefits for enterprises.

　　2. Social benefits

　　2.1 Breakthrough of key technologies

　　The breakthrough of key technologies has enabled China to truly possess internationally advanced A6V series product manufacturing technology. Rexroth’s hydraulic technology has been in the leading position in the world for a long time. By tackling key problems in localization, we have truly advanced international hydraulic component manufacturing technology, which has practical and long-term significance for changing the backward situation of basic hydraulic components in China. Breaking Rexroth’s technical monopoly, realizing the full localization of high-end hydraulic components, greatly reducing the supporting cost of the main engine, saving the national foreign exchange and promoting the national "Belt and Road" strategy have great social benefits.

　　2.2 Product performance and reliability have been greatly improved.

　　With the improvement of product performance and reliability, the company’s products have been designated as supporting products for military industry, which are used for supporting 09Ⅲ and 09Ⅳ steering gear, a new generation of self-propelled gun launchers and missile destroyers. The supporting products participated in the military parade of the 90th anniversary of the founding of the People’s Liberation Army in China at the end of July 2017, visited Hong Kong for the escort ship of the Liaoning carrier in July 2017, and went to the Gulf of Aden for escort operations and China naval parade in September 3, 2015.

　　Beijing, July 10 (Reporter Li Jinlei) According to data released by the National Bureau of Statistics on the 10th, the consumer price index (CPI) rose by 2.7% year-on-year in June. So far, the CPI increase has exceeded 2% for four consecutive months. Among them, the price of fruit rose by more than 40%, and the price of pig rose by more than 20%, which was the main reason for the increase of CPI in June. Experts predict that May and June will be the high point of CPI for the whole year, and then it will fall back.

　　CPI rose by more than 2% for four consecutive months.

　　Driven by the sharp rise in the prices of pork, fruit and other foods, the CPI increase in June was the same as that in May, and it continued to maintain the "2 era". So far, the year-on-year increase of CPI has exceeded 2% for four consecutive months since March this year.

　　In June, CPI rose by 2.7% year-on-year. It is basically consistent with the expectations of previous market institutions. Wind information data shows that the average forecast value of 20 research institutions for the year-on-year increase of CPI in June is 2.7%. Among them, the predicted maximum value is 2.9% and the minimum value is 2.5%.

　　Cao Heping, a professor at Peking University University of Economics, told Zhongxin.com that the price increase did not continue to expand in June, mainly because the price increase of vegetables declined.

　　The data shows that from the ring comparison, the CPI changed from flat last month to a decrease of 0.1%. In food, a large number of fresh vegetables were listed, and the price dropped by 9.7%, which affected the CPI by about 0.25 percentage points. On a year-on-year basis, the price of fresh vegetables rose by 4.2%, 9.1 percentage points lower than last month.

　　The prices of fruits and pork rose sharply.

　　The sharp rise in the prices of fruits and pork is regarded as the "culprit" for the continued rise in prices in June.

　　According to the data of the National Bureau of Statistics, the price of fresh fruit rose by 42.7%, which affected the CPI by about 0.71 percentage points. Pork prices rose by 21.1%, affecting CPI by about 0.45 percentage points.

　　Why do the prices of fruits and pork soar? Dong Yaxiu, director of the Urban Department of the National Bureau of Statistics, said that the price of fresh fruit rose by 42.7%, an increase of 16.0 percentage points over the previous month, which affected the increase of CPI by about 0.71 percentage points. In addition to climate and other factors, the lower price in the same period last year was also one of the reasons for the increase.

　　From the ring comparison, the centralized listing prices of fruits such as watermelon and peach decreased, but the prices of apples and pears continued to rise and the increase was relatively high. In addition, the heavy precipitation in some parts of the south affected the picking and transportation, and the prices of pitaya and pineapple rose. The national fresh fruit price rose by 5.1%, which affected the CPI increase by about 0.11 percentage points. At present, the price level is at a historical high.

　　Cao Heping believes that in addition to seasonal factors, the rising cost of fruit packaging is also the reason for the soaring fruit price. In addition to the tight supply caused by African swine fever, the increase in pork prices is also an important reason.

　　Wang Bin, deputy director of the Marketing Department of the Ministry of Commerce, said recently that the main producing areas of apples and pears suffered from abnormal weather last year, resulting in a significant decline in output; The continuous rainy weather in some parts of the south this spring has had a certain impact on vegetable production. Some of them are influenced by non-market factors. For example, due to the African swine fever epidemic, the number of live pigs has declined to some extent.

　　Will the prices of fruits and pork continue to soar?

　　For ordinary people, the most concerned question is, will the prices of fruits and pork continue to rise in the next period of time?

　　Cao Heping believes that with the influence of seasonality, weather, disasters and other factors decreasing, the logistics cost will decrease, and it is expected that the price increase of fruits and pork will gradually decrease.

　　Lian Ping, chief economist of Bank of Communications, analyzed that at present, the number of live pigs and the number of fertile sows are still declining rapidly, and the rising cycle of pork prices has been formed, which will still be an important factor driving CPI to rise in the second half of the year.

　　Wang Bin said that recently, with the temperature rising, a large number of seasonal vegetables and fruits have been put on the market, and the prices of fruits and vegetables have generally shown a downward trend, and the increase of pork prices has also slowed down compared with the previous period.

　　According to the monitoring of the Ministry of Commerce, from June 24th to June 30th, the average wholesale prices of 30 kinds of vegetables in 36 large and medium-sized cities nationwide decreased by 3.7% compared with the beginning of June, and by 11.9% compared with the beginning of May. The average wholesale prices of 6 kinds of fruits monitored dropped by 0.2% compared with the previous week, and the increase of pork prices dropped by 3.3 percentage points.

　　What is the price trend in the second half of the year?

　　Statistics from the National Bureau of Statistics show that CPI rose by 2.2% in the first half of the year, so what will be the price trend in the second half of the year?

　　Lian Ping said that considering the steady decline of non-food prices and core CPI, it shows that the pulling effect of total demand on prices is not obvious, and there is no significant inflation risk in the economy.

　　Lian Ping believes that the obvious decline of CPI hikes in the second half of the year and the effect of VAT tax reduction will, to some extent, offset the impact of rising pork prices on the year-on-year increase of CPI. It is expected that there will be no problem in controlling the average year-on-year increase of CPI within 2.5%.

　　Lu Yanchun, director of the price monitoring center of the National Development and Reform Commission, had predicted that May and June of this year would be the high point of CPI for the whole year, and then it would fall back and there might be a slight rebound at the end of the year. (End)

　　【Focus of annual meeting】

　　Want power from reform and vitality from innovation.

　　— — Strong voice from the 2018 annual meeting of Boao Forum for Asia

　　Guangming Daily reporter zhang yi Cao Yuanlong

　　Born because of reform and opening up, prospered because of reform and opening up — — Boao is the easiest place to touch the pulse of reform and opening up.

　　Boao Forum for Asia, let the world hear the strongest voice of China’s reform and opening up: In 2013, the Chairman of the Supreme Leader said in his keynote speech at the annual meeting of Boao Forum for Asia that "we will persist in reform and opening up"; In 2015, the Chairman of the Supreme Leader emphasized at the annual meeting of Boao Forum for Asia that "reform and opening up will be deepened more firmly".

　　Boao Forum for Asia will witness the resurgence of the spring tide of reform and opening up and set sail. This year coincides with the 40th anniversary of China’s reform and opening up. The Chairman of the Supreme Leader was invited to attend the annual meeting of Boao Forum for Asia and will deliver an important speech, summarizing and combing the 40 years of China’s reform and opening up, and charting the future direction.

　　Wanghai: The past and the future meet here

　　"Reform and opening up" is the biggest hot spot of the 2018 annual meeting of Boao Forum for Asia.

　　Facing the gate of the main venue of Boao Forum for Asia, the visual exhibition commemorating the 40th anniversary of China’s reform and opening up with the theme of "New Era and New Journey" has made people walk through 40 years in light and shadow.

　　In Boao, reform and opening up are China and the world in the minds of foreign guests — — Chris Marin, president of American Lena International Company, told Guangming Daily that China’s development in the past few decades has benefited from reform and opening up. The reform and opening up has created a huge market in China, which has benefited the American business community a lot. It can be said that reform and opening up are also beneficial to Sino-US relations.

　　In Boao, the reform and opening up is the global thinking of China scholars — — Gu Xueming, president of the Institute of International Trade and Economic Cooperation of the Ministry of Commerce, said: "In a sense, the current economic globalization is facing challenges and may also require worldwide reform and opening up. China’s practice in the past 40 years can provide some useful lessons."

　　The reform and opening up not only brought epoch-making changes to China, but also had a great impact on the world. China has become the second largest economy in the world. Since the 18th National Congress of the Communist Party of China, comprehensive deepening of reform has broken down the institutional and institutional obstacles that hinder development, and 360 major reform plans and more than 1,500 reform measures have been introduced, making China develop vigorously and generate.

　　Wang Yi, State Councilor and Foreign Minister, revealed that the keynote speech by the Supreme Leader at the Boao Forum for Asia will give the most authoritative explanation on China’s great achievements in reform and opening up, its important experience and enlightenment, its world significance and influence, and how China will promote opening up, deepen reform and start again in the new historical moment.

　　Watching the tide: China will start again after reform and opening up

　　"Foreign friends and guests from all walks of life want to perceive the direction of China policy in the new era and find their own development opportunities. This annual meeting of Boao Forum for Asia will be a very good window." Yang Xiyu, executive vice president of Boao Forum for Asia Research Institute, said.

　　In the 2018 New Year message, the Chairman of the Supreme Leader emphasized that reform and opening up is the only way for the development and progress of contemporary China and the only way to realize the Chinese dream. We should take the opportunity of celebrating the 40th anniversary of the reform and opening up to the outside world, open the way on every mountain, bridge the gap when encountering water, and carry out the reform to the end.

　　In the past five years, the changes in China have been profound and fundamental. The main contradiction in our society has been transformed into the contradiction between the people’s growing need for a better life and the unbalanced development. Socialism with Chinese characteristics has entered a new era, facing many new tasks and challenges.

　　The reform and opening up since 1978 is a key measure to determine the fate of contemporary China. Forty years later, China planned and promoted reform from a higher starting point. Different from the state of "crossing the river by feeling the stones" 40 years ago, today’s reform in China has entered the fast-flowing deep water area, and it is going to step into an "upgraded version" led by top-level design. The new policy signals released at the Boao Forum for Asia will surely attract the attention of the world.

　　Dai Xianglong, former governor of the People’s Bank of China, said at the sub-forum of "Asian Economic Forecast" of Boao Forum for Asia held on April 9th that the speed of economic growth in China is not as high as before, but the quality of growth is improving. After 40 years of reform and opening-up, along with GDP growth, environmental improvement, efficiency improvement, income increase and changes in the development stage, China won’t simply pursue speed in the future, but it doesn’t want speed, but it needs quality speed. "In the next 20 years, even by the middle of this century, Asia will still be the fastest growing region in the world, and the very important reason is the strong development of China. To achieve high-quality growth in China’s economy, it is necessary to carry out structural reforms on the supply side, vigorously cultivate new kinetic energy, and eliminate backward production capacity. " Dai Xianglong said.

　　"The open door of China will never be closed, it will only grow bigger and bigger."

　　"China will be more open and benefit the world to a greater extent."

　　Entering a new era, China has embarked on a new journey of further going to the world and developing a higher-level open economy. It is embracing the world with an unprecedented open attitude and bringing more confidence to the world. Boao Forum for Asia will convey China’s determination to deepen reform and open wider to the outside world and China’s voice to the world.

　　Sailing: innovation adds vitality to world development

　　On the afternoon of the 9th, Boyaxuan, Boao Forum for Asia International Conference Center.

　　"Welcome to Boao Forum for Asia!" The welcome language of the intelligent question-answering robot Xiao I attracted Joel Rue, chairman of the French "Bridge" think tank, to stop and interact: "Hello Xiao I, nice to meet you." After asking and answering questions, Lu Ai was amazed at China’s achievements in scientific and technological development. He told reporters that China’s scientific and technological innovation ability has made rapid progress, which has played a very good role in boosting economic development.

　　Innovation is the first driving force of economic development. Turning over the meeting schedule of this Boao Forum for Asia, innovation is a hot topic that cannot be ignored. Sub-forums such as future transportation, future production, future communication, digital economy: the value of wisdom and a new round of technological revolution are colorful.

　　What will the traffic be like in the future? He Xiaopeng, chairman of Xpeng Motors, believes that the future transportation is actually the improvement of efficiency, whether it is car or railway, whether it is air or space travel, it is the improvement of travel radius for users. Today, all technical policies and entrepreneurial actions are making efforts to this end. Liu Hualong, chairman of CRRC Group Co., Ltd. added that in addition to high efficiency, the future traffic should also include green, wisdom and harmony, which are the direction of future traffic tracks.

　　In the future production, how will machines and people coexist? Richard edmondson Bailey, president of Hewlett-Packard Asia-Pacific, said that innovation comes from human beings, not some computers. In the future, some jobs will be replaced by machines, but such changes will take time and everyone will have the opportunity to receive corresponding education and training. Dong Mingzhu, chairman of Gree Electric, said that people are the greatest in any era. It is impossible to grow without hard work, so challenge is our eternal topic.

　　Of course, innovation is comprehensive innovation. Participants believe that comprehensive innovation means not only scientific and technological innovation, but also institutional innovation. Only comprehensive innovation can truly inspire inexhaustible motivation.

　　Pakistani Prime Minister Abasi said that Asian countries have been integrating in the fields of economy, trade, technology and energy in recent years, and they need the guidance of openness and tolerance. With reform, opening up and innovation, Asia has created many economic miracles and become the most dynamic region in the world. In the future, it needs more power and vitality from reform, opening up and innovation.

　　Boao quick tour

　　China is going further to the world and developing an open economy at a higher level. Boao Forum for Asia will convey China’s determination to deepen reform and open wider to the outside world and China’s voice to the world.

　　The Asian Media Summit was held on April 9th. More than 140 heads of mainstream media from 40 Asian countries, as well as more than 300 representatives of Asian cultural scholars and relevant parties attended the opening ceremony.

　　(Guangming Daily, Boao, Hainan, April 9 th)
