The hot weather has been going on all over the country for many days. Such heat, even if you just stand still in the sun, will soon break out in a sweat. But there are still many people who stick to their jobs at high temperatures. Protect the safety, traffic, communication, sanitation and greening of the city … Thanks to them, let our life be as usual.

　　Xinhua News Agency, Zhengzhou, January 4th, New Media Specialist (Reporter Ma Yizhen) In response to the recent online incident of "Henan college students marrying classmates’ mothers", Weibo, the official of Henan Provincial Public Security Bureau, released a message saying that similar rumors have been spread in many places for several years and are false news.

　　Recently, a news that "Henan college students marry classmates’ mothers" attracted attention on the Internet. According to the news, a handsome 21-year-old college student married a 55-year-old divorced middle-aged aunt in a hotel in Henan. Incredibly, this middle-aged aunt is actually the biological mother of the groom’s college classmates.

　　The news also said, "It turns out that the truth behind the incident is actually like this. The groom is young and handsome, while the bride looks very young at the age of 55, just like a young girl in her twenties … …”

　　After testing, it is found that there have been similar articles since 2013, involving different places such as Guangzhou, Wuxi and Pingtan, and the pictures are the same, the story is the same, and most of the words are the same. These articles all mention that classmates and mothers use some kind of skin care products, carry out beauty treatment and so on.

　　Some experts in journalism and communication believe that, in view of the proliferation of fake news, a governance and restraint mechanism should be established, and strict control and strict investigation should be carried out through legal and administrative penalties.

　　"The more authentic and natural the food, the safer and healthier it will be", which is the idea of many people now. When people buy food in the supermarket, "no addition" and "zero addition" often become the selection criteria. However, recently, the State Administration of Market Supervision issued the Measures for the Supervision and Administration of Food Labeling (Draft for Comment) (hereinafter referred to as the "Measures") to solicit opinions from the public. The "Measures" clearly stipulate that "no addition" and "zero addition" cannot be used in food. Why is this?

　　"Food additives are the needs of seasoning and quality assurance, and modern food production and processing are inseparable from food additives, which is really ‘ Zero addition ’ There is almost no food, so-called ‘ Zero addition ’ It’s just a trick of business promotion. " Wang Hao, an associate professor at the School of Food Engineering and Biotechnology, Tianjin University of Science and Technology, said.

　　Therefore, once the regulations such as "zero addition" are officially passed, it will be beneficial to standardize food labeling and greatly limit the operation of some businesses to fool consumers with "zero addition"; It is conducive to strengthening the supervision and management of food labeling and protecting consumers’ right to know and choose; It is conducive to guiding consumers to correctly understand food additives and protecting the legitimate rights and interests of consumers and food producers and operators.

　　Modern food production and processing are inseparable from additives.

　　With the improvement of living standards, consumers’ standards for eating are getting higher and higher. Many people are flustered at the sight of a string of unfamiliar chemical terms in food instructions, and they are worried that the irregular use of additives in food will bring safety problems, even to the point of talking about "adding". Once food safety problems occur, additives often become "back-pot men".

　　"Food additives are one of the most active, developing and improving parts in the food industry. It is a synthetic or natural substance added to food to improve the quality of food such as color, fragrance and taste, and to meet the needs of anti-corrosion, preservation and processing technology. " Wang Hao said, "Food additives have greatly promoted the development of food industry. Only using food additives can prolong the storage period of food, ensure food safety, provide people with more delicious and nutritious food and meet people’s different needs. Food additives are the product of the development of modern food industry. Without food additives, there would be no modern food industry. Therefore, food additives are also known as the soul of the modern food industry. "

　　"After entering the food industrialization, it is quite difficult for prepackaged foods, which has been processed by enterprises, to find food without food additives." Wang Hao said that some people think that they can stay away from additives when cooking at home. In fact, there are many additives in various seasonings used in cooking. For example, soy sauce contains food additives such as caramel color, potassium sorbate and sodium benzoate, and anti-caking agents added in salt and antioxidants added in edible oil are all food additives. This is why edible oil has no "spicy taste" after being put for a long time, and salt is not easy to agglomerate in summer.

　　"Some people will compare the ingredient list when buying food, and think that foods with fewer kinds of food additives are healthier than foods with more additives." In this regard, Wang Hao emphasized that "as long as food additives are used legally and in moderation, the number of types added does not affect the quality and safety of food."

　　Writing "zero addition" does not necessarily mean that there are no additives.

　　"If illegal additives are not added, it’s like a salted duck egg package that says ‘ Sudan Red ’ is not added; Similarly, it should not appear in the product, let alone on the packaging, because it is the responsibility and obligation of the manufacturer that the product does not contain illegal additives. " Wang Hao analysis, and if "zero addition" refers to the absence of legal additives, this situation is even more interesting. The state originally stipulated that additives can be added, but the products are marked in bold and bold, which will cause misunderstanding to consumers and think that these additives are harmful.

　　"In addition, some business logos will not say that no specific substances have been added, but only that they have not been added in general, which makes people think that this is food without any additives." Wang Hao said, for example, some foods that don’t need preservatives themselves, because they don’t have an environment for corrupt microorganisms to "have children", such as honey (high sugar), instant noodle cakes (dry) and pickled foods (high salt). Although these foods may not contain preservatives as food additives, they will contain other food additives, which will mislead consumers.

　　Wang Hao pointed out that the real problem is that some food packages are secretive, and although they are marked with "zero addition" and "no addition", they are actually added. In other words, the so-called "zero-addition" and "no-addition" have become the propaganda tactics of merchants, which not only damages consumers’ right to know, but also disrupts the competition order in the food market. Therefore, it is forbidden for food production and operation enterprises to mark "no addition" and "zero addition" on food packaging, which not only helps to standardize and restrict the production and operation behavior of enterprises, but also fully protects consumers’ right to know.

　　"Zero addition" does not mean healthier and safer.

　　"In fact, even if it’s true ‘ Zero addition ’ It does not mean that it is safe, healthy and nutritious. " Wang Hao explained that, for example, food preservatives are a major category of food additives, which are used to prevent or delay food spoilage and prolong food preservation and storage period. There are some foods with high protein content, and preservatives must be added to ensure the quality and safety of the products, otherwise it will be more prone to spoilage. Therefore, adding preservatives in a suitable range is actually a guarantee for consumer food safety.

　　"Sometimes the right amount of food additives can reduce and eliminate the output of harmful substances in the food production process." Wang Hao, for example, said that when curing food, adding proper amount of ascorbic acid, which is commonly known as vitamin C, can effectively reduce the content of carcinogenic nitrite.

　　"For example, many people like to eat air-dried cured meat, fermented foods and bean products. In the production process, it is easy to produce botulinum that can release highly toxic toxins. A very small amount can paralyze nerves, which in turn causes respiratory failure and death." Wang Hao said that in the industrial production of this kind of food, professional technicians are responsible for controlling the usage and dosage of additives, and there are also standard production procedures to reduce the generation of harmful substances. In the production process and before entering the market, we should also carry out quality inspection on products according to national standards.

　　"Standardizing the use of food additives has the function of ensuring safety, ‘ Zero addition ’ There will be no more advantages in security. " Wang Hao said.

　　Xinhuanet Beijing April 22nd (Wang Ying) Today is the 49th Earth Day. Protecting the earth’s environment and protecting the common home have attracted much attention. There is only one earth for human beings. How can we cherish our blue home? These little efforts in life make it easy for us to add green to the earth.

　　Turn off the lights without wasting power resources.

　　Due to negligence or trouble, many people often forget to turn off the lights or power in their lives. At present, 60% of the electricity used in our life depends on burning coal, and 400 grams of coal is burned for every kilowatt hour. Burning coal not only consumes the earth’s resources, but also produces a lot of carbon monoxide, sulfur dioxide, nitrogen dioxide and dust, which seriously pollutes the environment. Develop the habit of turning off the lights at will, and unplug the power supply for unused electronic equipment in time, which can not only save electricity, but also protect natural resources.

　　Green and low-carbon travel is environmentally friendly and healthy.

　　In recent years, the concept of green and low-carbon travel has been deeply rooted in people’s hearts. In daily life, if you are a car owner, if conditions permit, you can try to walk, ride a bike or take public transport to reduce the use of motor vehicles. When the weather is fine, you can also go outdoors for cycling and walking, which not only exercises your body, relaxes your body and mind, but also reduces energy consumption.

　　Save paper to make the forest more lush.

　　In daily work and life, the consumption of paper is amazing. As we all know, paper is made of trees. The more paper is consumed, the more the number of trees decreases. Save paper from scratch, such as printing documents can be double-sided; Used paper can be used in reverse; Use paper reasonably and refuse to use it excessively (such as pumping paper and toilet paper); Put a handkerchief in your pocket to reduce the use of paper towels.

　　Use less plastic bags to protect soil and atmosphere.

　　The pollution of plastic bags to soil is self-evident. To protect the global environment, we should reduce the use of plastic bags and keep cloth bags or reusable shopping bags when going out. At the same time, use disposable things (such as disposable bowls, chopsticks and cups) as little as possible.

　　Garbage sorting makes the living environment fresher

　　We produce a lot of garbage every day, and disorderly mixing not only leads to the spread of odor, but also pollutes soil and groundwater. In recent years, garbage classification has been widely advocated, and we should also respond positively in daily life, separate waste, make use of existing manufacturing capacity, recycle recycled products, and turn waste into treasure.

　　Save water, the blue planet can’t lose a drop.

　　A dripping faucet wastes 1 to 6 liters of water a day, and a leaky toilet wastes 3 to 25 liters of water a day. Water resources are not inexhaustible. To save water, we should start from the dribs and drabs of life (washing, bathing, cooking, washing cars, washing clothes, etc.). For a simple example, the flushing toilet is the key equipment for household water use. In the past, many families directly discharged the wastewater, but now many people began to keep the wastewater for flushing the toilet.

　　Participate in planting trees to add more green to the earth.

　　A 50-year-old tree produces oxygen worth about $31,200. Absorbing toxic gases and preventing air pollution is worth about $62,500; Increase the soil fertility value by about $31,200; Water conservation is worth $37,500; Providing breeding grounds for birds and other animals is worth about $31,250; Resulting in protein worth $2,500. Excluding the value of flowers, fruits and wood, the total value is about $196,000. In life, take part in more tree planting activities to add more green to the earth.

　　Buying energy-saving appliances saves more than electricity bills.

　　According to relevant data, under the same wattage, an energy-saving lamp saves 80% more energy than an incandescent lamp, prolongs its average life by 8 times, and radiates only 20%. This is just a light bulb. If we replace all the high energy-consuming appliances in our home with energy-saving appliances, or buy energy-saving appliances directly, we can not only save electricity expenses, but also reduce electricity consumption.

1905 movie network news On November 20th, director Chen Kaige was invited to attend the film academic observation jointly organized by the Academic Affairs Office of Beijing Film Academy and the director department, and shared the film from scratch with the teachers and students present after the screening. More than 700 seats in the standard screening hall were packed, and the teachers and students in the school cherished the opportunity of face-to-face communication with director Chen Kaige.

　　　

In the post-screening exchange, Chen Kaige not only sincerely thanked the creative team of that year for "all their great contributions"; I also talked with you about the wonderful past that Leslie Cheung was Cheng Dieyi, and frankly said that "this experience is only this time"; He also expressed his concern and support for young creators, bluntly saying that "the film festival is not only a promised place for movies, but also an inspirational place representing youth and hope", and he hoped that the film festival could focus more on young creators.

　

Sincerely thank all the founders for sighing that Leslie Cheung has given us the only experience.

　　　

After the academic observation and screening of the film Farewell My Concubine, the film director Chen Kaige took the stage to share his feelings with all the teachers and students. Thanks to the hundreds of staff members who fought together in those years, especially Gu Changwei and Tao Jing, the alumni of the same session directed by Chen Kaige, "Photographers and sound recorders were very young at that time, but they created such magnificent images and powerful voices", as well as assistants and collaborators at that time, Zhang Jinzhan, Bai Yu, artist Zhanjia Yang and composer Zhao Jiping, "all made great contributions". ZhangFeng yi, one of the leading actors, is a leader in the performance department of Class 7 and Class 8 of Nortel. Director Chen Kaige highly praised his performance, saying that "his Duan Xiaolou is wonderful" and was moved by Mr. ZhangFeng yi’s dedication in filming.

　Director Chen Kaige also talked with you in more detail about the origin of filming, from being invited twice by producer Feng Hsu at Cannes International Film Festival to having various exchanges with original author Li Bihua. He not only gave Feng Hsu the first credit for Farewell My Concubine, but also praised Li Bihua as "the mother of Farewell My Concubine, and her novels laid an excellent foundation for the film" and "man of great talent, fantastic ideas". Li Bihua, as one of the screenwriters, also traveled from Hongkong to Beijing during the script creation stage to participate in the exchange and discussion between director Chen Kaige and another screenwriter, Reed. One of director Chen Kaige’s creative habits is to communicate with the screenwriter for a long time in the script stage, give a big outline for the characters, plot and story direction, and then discuss with the screenwriter, and finally realize it.

Especially in Farewell My Concubine, the time has been extended to 50 years, and the script structure is very complicated. In about half a year, director Chen Kaige and two screenwriters, Li Bihua and Reed, went through the process of affirmation, negation and reaffirmation. There is no routine, only the understanding and confirmation of the characters. After the first draft of the script was written, Reed took a pen and asked Chen Kaige to draw a circle in the satisfied scenes. If he was not satisfied, he would revise it again. After reading it, Director Chen Kaige only drew a few circles in the first draft, and then took everyone into a new round of discussion and revision. This manuscript is still precious. The script has been polished over and over again, and it is constantly enriched and perfected. Especially at the end of the script, Chen Kaige emphasized that the ending of the two people meeting in the bathroom in Hong Kong has no power. Only letting Cheng Dieyi follow the pace of Yuji’s fate is the only reasonable treatment that conforms to the character’s character logic.

　　

　In the actor’s part, Chen Kaige naturally talked about Leslie Cheung along the role of Cheng Dieyi, and what Chen Kaige always remembers is his first meeting with Leslie Cheung — —

　　　　

"The first time I met Leslie Cheung was when the first draft of the script was not finished. I have to tell him this story orally. Ms. Feng Hsu made arrangements for meeting in advance at the coffee shop of Mandarin Hotel. In the future, he jumped down from the same building. He is very gentle and quiet, and I speak in a hurry, for fear that we will have a language barrier. I speak Mandarin, and he is an actor who speaks Cantonese. I’m afraid what I said won’t impress him. I have also said on other occasions that he smokes a lot and his fingers are shaking all the time. In the process of speaking, I was skeptical and psychologically repulsive, so I asked myself, how do I know that he is the right person to play Cheng Dieyi? I don’t even know if he is a good actor. My story happened in China, and he is a Hong Kong person. Can he understand such characters and stories? And here I am, madly telling a story that may be rejected.

He never spoke, just listened, sometimes he looked up at me, and sometimes he didn’t look at me. But when I finished speaking, it suddenly dawned on me that he was Cheng Dieyi. Because I think he is like a person sitting in the bow of this story ship. After the ship moves, the lakes and mountains are changing all the time, and these light, shadow and water waves all reflect on his face. I don’t want to say that he is acting, but he is following Cheng Dieyi closely, approaching him, expressing him and loving him in a very subtle way. At this time, he stood up and shook hands with me and said,’ Thank you for telling me the story. I am Cheng Dieyi.’ This is a hair-raising moment. "This also made Chen Kaige identify with Leslie Cheung — — This is the only experience.

　

Looking back, I hope the film festival will pay attention to young people and create new possibilities.

　　

After the film Farewell My Concubine was born, it won the Palme d ‘Or Award at the 46th Cannes International Film Festival in 1993, and won the Golden Globe Award for Best Foreign Language Film in the United States and two nominations for Best Foreign Language Film and Best Photography at the Oscars the following year. It was rated as one of the 100 best films in the world by Time Magazine, which has produced great international influence.

　　　

From Farewell My Concubine, Chen Kaige, the director, fought in major film festivals with his works in his youth, and the film festivals did give him honor and support. In Chen Kaige’s view, a good film festival "is full of charm and becomes the hall that filmmakers all over the world yearn for because it is unknowable." "You don’t know what kind of movie form a new trend will run out, and the new possibilities that keep emerging surprise you." Therefore, the film festival "is not only the promised land of movies, but also an inspirational place representing youth and hope". Chen Kaige believes that film festivals and professional organizations such as China Film Directors Association should pay more attention to those "young people who are happy, confused, miserable and give up everything for movies" and let them stand on the podium.

　　　

Director Chen Kaige’s sharing touched the teachers and students of Nortel who were present. In the subsequent interactive session, Chen Kaige answered the questions raised by the students in the audience one by one, and his serious and professional attitude moved people.

　　Yesterday, Jiangsu Education Examinations Institute held an open day for marking the college entrance examination. Yangzi Evening News reporter and 12 candidates and parents’ representatives from Nanjing came to the marking site of the college entrance examination, visited the answer sheet storage group, scanning group and Chinese subject marking group successively, and got in touch with the marking work of the college entrance examination at zero distance, feeling the fair, just, rigorous and orderly working atmosphere of the marking of the college entrance examination.

　　site

　　The electronic image of each candidate’s answer sheet is kept for 4 years.

　　At the examination paper scanning point of the Provincial Education Examinations Institute, the staff are busy unpacking and scanning the examination paper, storing the information in the warehouse, and scanning it through a high-speed special scanner, cutting the contents of the examination paper into pictures, encrypting the candidates’ names, admission ticket numbers and other information, and sending them directly to each marking point through special optical fiber.

　　Fu Yaozhang, director of the Network Information Center of the Provincial Education Examinations Institute, said, "The scanning number of all answer sheets in all subjects must be consistent with the data of candidates participating in the arrangement, and the electronic image of each candidate’s answer sheet should be kept for 4 years."

　　As in previous years, this year, all subjects of the college entrance examination in our province will continue to carry out computer-aided online marking, and the Provincial Education Examinations Institute will undertake the scanning of answer sheets and the marking of multiple-choice questions. For non-multiple-choice questions, the marking of Chinese, mathematics and foreign languages will be handled by Nanjing Normal University, and the marking of six selected subjects and small languages will be handled by Nanjing University.

　　Wu Renlin, vice president of the Provincial Education Examinations Institute, said that there were more than 2,200 marking teachers this year, all of whom were selected from the database of marking teachers in the province. Among them, the marking teachers who mark the test questions with large scores and strong subjectivity, such as composition questions, discussion questions, calculation and solution questions, experiments, etc., all have more than 3 years of teaching and research experience and some marking experience.

　　"Four-evaluation system" makes marking more fair

　　The marking method is also particular: the "four-evaluation system" is implemented in the non-multiple-choice part of all subjects. "After the test paper is scanned and entered into the computer, it will be cut into several blocks. After cutting, the computer will automatically process all the blocks with secret numbers. All the secret numbers correspond to the candidates one by one, but the marking teacher can’t see any identity information of the candidates, and no one can change the answer sheets after secret number processing, which can ensure the fairness and justice of marking work." Wu Renlin said that each marking group marked the cut blocks separately, and each block was randomly distributed to two different marking teachers for independent marking. If the scores scored by the two people are within the scoring threshold set by the subject marking expert group, the average of the scores scored by the two people is taken; If it exceeds the scoring threshold, it will be submitted to the third marking teacher for three evaluations; If it still exceeds the scoring threshold, it will be submitted to the fourth marking teacher for four evaluations. The difficult problems encountered in the marking process are collectively discussed and solved by the marking expert group.

　　Marking progress

　　Chinese: the score of the test questions is accurate to 1 point.

　　Professor Cao, a member of the Chinese marking group of the college entrance examination, introduced that this year’s marking was more orderly, rigorous, scientific and stable. On the second day after the end of the college entrance examination, marking experts entered the marking site to prepare for marking. At present, the scores of most topics are accurate to 1 point, ensuring that the hard work of each candidate is properly reflected.

　　Professor Cao said that the marking of Chinese in the college entrance examination has maintained a steady and progressive trend. "This year, the Chinese in the college entrance examination is generally stable. From the results of the trial evaluation, it is easier for candidates to get started, and their thoughts and feelings can be expressed, and the degree of discrimination in the test papers is ideal. For the composition evaluation that candidates and parents care about, we will focus on correcting the phenomenon of high scores and low scores in the process of marking and correcting ‘ False and wrong cases ’ Strictly check the excellent composition and carefully identify the fake phenomenon of low scores and high scores. In addition, the team leader and the staff of the expert group will repeatedly check without any dead ends, and organize the verification team to conduct spot checks on the composition marking. "

　　Mathematics: More than 8 solutions have been prepared for each problem such as function.

　　The math marking team for college entrance examination consists of math teachers from NTU and NTU and more than 80 middle school teachers. Professor Yan, a member of the math marking group and professor of Nanjing Normal University, introduced that the math marking group organized a subject expert group and each topic leader to investigate the answers of the province’s math test papers, and learned about the possible answers of candidates through full investigation. "The expert group has been carefully formulating the scoring rules. For example, function problems and many big problems have provided more than eight solutions, so it is necessary to formulate scientific evaluation criteria. Decompose each solution into knowledge points, and ensure that homogeneous knowledge points give the same scores and fair standards. Once a new solution is found, the marking teacher must report to the subject expert group in time, and then the experts will discuss and study the scoring rules of this solution, and they are not allowed to evaluate it privately. "

　　Professor Yan revealed that the mathematics marking of the college entrance examination should be completed before the 20th.

　　English: enrich the grading rules and take care of a variety of reasonable composition viewpoints and angles.

　　Professor Shao, a member of the English marking group, introduced that the expert group carefully analyzed the characteristics and reference answers of "task-based reading" and "written expression" and refined the evaluation criteria; The writing points and sub-points of the composition part are subdivided. At the same time, through a large number of sample papers covering various regions and examination rooms, starting from the actual situation of candidates’ answers, the scoring rules are enriched and a variety of reasonable composition viewpoints and angles are taken care of.

　　English marking implements a three-level quality monitoring system of subject expert group, marking team leader and team members. Each paper has been reviewed by team members for multiple rounds back to back, arbitrated or spot-checked by team leader, and monitored and spot-checked by experts. At the same time, the online marking system and monitoring system have a clear division of labor. According to the characteristics of English subjects, the software is designed scientifically and matched reasonably, and equipped with real-time marking, quality statistics, bad error monitoring and early warning systems to avoid misjudgment as much as possible.

　　Yangzi Evening News/Yangyan reporter Yang Tianzi

　　China Rural Network News (Reporter Jiang Wenlong, Zhu Haiyang) The landing of super typhoon "Likima" has had a great impact on Zhejiang’s economy. According to the latest statistics, as of 8: 00 on the 11th, the affected area of crops in Zhejiang Province was 173,000 hectares, with a total harvest of about 22,000 hectares, 34,000 houses damaged due to the disaster, and the direct economic loss was more than 14.57 billion yuan. At present, the Zhejiang Provincial Department of Agriculture and Rural Affairs has issued a notice, demanding that all efforts be made to resume agricultural production after the typhoon.

　　Previously, Zhejiang has released agricultural disaster prevention and mitigation technical measures such as planting, animal husbandry and fishery. In order to effectively strengthen the guidance service and strengthen the implementation of technical measures, all parts of Zhejiang are coordinating relevant forces, selecting a group of people with familiar business and excellent skills to form a disaster relief guidance group, and rushing to the scene at the first time to investigate and understand the disaster situation, visit and sympathize with the affected farmers and agricultural production and operation entities, and help solve practical difficulties in agricultural production.

　　Zhejiang requires that all localities should use seeds, pesticides, fertilizers, disinfectants, vaccines and other reserve materials in time according to the disaster situation and demand, coordinate and organize the transfer of agricultural production materials between regions in time, and give priority to ensuring the supply of agricultural disaster relief materials. If the affected fields need to replant vegetables and other crops, it is necessary to coordinate and organize relevant seedling enterprises, pay close attention to breeding, and do a good job in docking seedlings.

　　The reporter learned that local agricultural disaster relief guidance groups have gone to the front line of disaster relief. On the 10th, technicians from Yueqing Agriculture and Rural Bureau went to Nanyue Egg Duck Breeding Community to guide the post-disaster recovery work, and went to the fields of farmers insured by policy agricultural insurance to check the disaster situation. Technicians from Deqing County Agricultural and Rural Bureau visited agricultural producers such as aquatic products, orchards and shrimp farming to survey and guide the response of agricultural typhoon prevention; Agricultural technicians from Xiangshan County Agriculture and Rural Bureau went to Dingtang Town Elemental Egg Duck Breeding Base and Shipu Town Grape Planting Base to provide guidance on post-disaster recovery.

　　The reporter learned that the typhoon node was special and had a great impact on fishery production in Zhejiang. Zhejiang Fishery Mutual Insurance Association has organized forces to rush to the disaster-stricken sites all over the province for the first time to collect survey information and statistics on damage data. Pacify members’ anxiety, and do a good job in claims settlement and service in post-disaster fishing areas. On the evening of the 9th, the Provincial Institute of Marine Fisheries dispatched 15 experts overnight to form a disaster relief expert guidance group, especially for Yueqing and Dongtou, which were seriously affected by the disaster, to visit and inspect the relevant breeding and seedling raising bases and enterprises on the spot, and to assist the local agricultural and rural departments to carry out disaster relief technical guidance.

　　The report of the 19th National Congress proposed that we should implement the new development concept and build a modern economic system.

　　In this regard, it is an important content to improve the system and mechanism of promoting consumption and enhance the basic role of consumption in economic development. In recent years, consumption has replaced investment as the first driving force of economic growth. Behind this, the innovation of payment methods brought by technical means has contributed greatly, and installment consumption is one of them. "Spend tomorrow’s money and enjoy today’s resources", whether it is life consumption such as digital electronics, home appliances and furniture, or service consumption such as training, tourism and entertainment, the tentacles of phased consumption have extended to all aspects of life.

　　Can installment consumption really make people enjoy life ahead of schedule easily? In the face of the network staging platform with spurt growth, how should consumers rationally stage and make good use of staging?

　　How hot is the market?

　　"It is no exaggeration to say that more than 90% of college students around me have used installment consumption, and food, clothing, housing and transportation, leisure and entertainment can all be solved by installment consumption."

　　"With children at home, the requirements for environmental sanitation are relatively high. My British Dyson vacuum cleaner was made of JD.COM white stripes. I often shop in JD.COM, and I can avoid paying interest by installments with coupons. It is much more economical to installment this year than to use a bank credit card. " Hao Yihang, an employee of a large state-owned enterprise in Beijing, is a fan of JD.COM IOUs. In his words, the slogan of "Consumption by stages, so that youth does not leave blank" attracts young people. The service of "Shopping first, paying later" and "30 days interest-free and staging at will" makes life consumption zero obstacles. "Consumption by stages is so cool!"

　　It reduces the pressure of one-time payment, and the relaxed shopping experience of "installment consumption" makes people happy. Hao Yihang said that Apple’s upcoming iPhone X, which he also intends to buy in stages, will not cause economic pressure and keep up with the trend. Staging consumption can make the monthly salary diversified and meet more new consumption needs.

　　The application method is flexible, the application procedure is convenient, there is no need for mortgage guarantee, and the approval speed is fast. With these characteristics, installment consumption quickly wins the favor of young people. The group represented by "post-90 s" grew up in the era of rapid development of the Internet, and accepted new technologies, new things and new products with a high degree. Pursuing efficiency and enjoying the present are their main consumption concepts, and this group is the main force of phased consumption.

　　"It is no exaggeration to say that more than 90% of college students around me have used installment consumption, and food, clothing, housing and transportation, leisure and entertainment can all be solved through installment consumption." Wang Peng is a junior in a university in Beijing. As early as when he first entered school, he began to use installment consumption, which was very convenient.

　　"This year, the money I signed up for the TOEFL training class was solved by stages. A TOEFL class costs more than 30 thousand yuan, and I ask my parents directly. I’m a little embarrassed. After using the staging platform, I will take out some money from the living expenses to repay the loan on schedule every month. Although there is some interest, I think it is worthwhile. " Wang Peng said that installment consumption is very common among college students, ranging from buying computers and mobile phones, education and training, to recharging phone bills and purchasing tickets for movies. They all like to choose installment.

　　In the past two years, the installment consumption platform has developed rapidly, especially the "internet plus installment consumption" platform has made up for the shortcomings of the traditional financial industry and served the groups that it failed to cover. Recently, the industry has welcomed the "regular army", banks have returned to the field of campus installment consumer credit, and the market is gradually standardizing. According to the forecast of relevant institutions, in the past five years, the average annual growth rate of installment consumption loans exceeded 20%.

　　How tempting is it?

　　Some merchants deliberately weaken the intermediary fees and induce consumers with the gimmick of "low threshold, zero interest and zero down payment", while the handling fee and service fee behind the products are actually higher than the interest.

　　"I obviously bought a 5799 yuan mobile phone, but the final repayment was more than 1700 yuan, which means that I spent nearly 8000 yuan on this mobile phone. Although the mobile phone was used more than one year in advance, it also paid a price. " Speaking of installment consumption, Zhao Xiaoxian, a chef in a restaurant in Hefei, Anhui Province, felt quite helpless. "It is very difficult for migrant workers like me who have no stable income to apply for bank credit cards. Online merchants lied to me that installment consumption threshold is low, procedures are convenient and interest is low. However, in the final calculation, the handling fees are higher than the interest. "

　　Dong Ximiao, a senior researcher at Chongyang Financial Research Institute of Renmin University of China, believes that the staged consumer market is developing rapidly, but the good and the bad are mixed, and many services are falsely advertised. The main purpose of staging business on the consumer platform is to expand users’ staging consumption, but the way to expand customers mainly comes from offline, and salesmen are easy to cheat and induce consumers for the sake of performance. Some merchants deliberately weaken the intermediary fees, and basically induce consumers with the gimmick of "low threshold, zero interest and zero down payment", while the handling fee and service fee behind the products are actually higher than the interest, which makes consumers feel miserable.

　　"The development of bank credit card business is relatively mature, and both the bank’s own risk control system and regulatory regulations are relatively perfect. However, the staged market has outstanding problems such as false propaganda and induced sales promotion in a fierce competitive environment. " Dong Ximiao said.

　　The installment consumption business of traditional commercial banks is standardized, mainly for consumers with stable income. Consumers have lower risk in using it and can effectively protect their rights and interests. The market gap that traditional commercial banks can’t cover has inspired the rise of Internet staging platforms, which have low thresholds and are aimed at social groups such as students and migrant workers. Coupled with the lag of regulatory policies, some disadvantages of installment consumption are constantly emerging.

　　For example, it is inevitable that unqualified consumers will default in time on the staging platform. Salespeople usually "salute before soldiers", but the effect of "collection" will be linked to performance. Because there is no standardized and legalized collection supervision policy at present, there are different kinds of violent collection behaviors in the staged market in reality.

　　The risk of disclosure of personal information makes installment consumption a safety hazard. Many people have encountered the problem of "receiving a collection message without a loan" and "being registered under an assumed name without registration". Most people will choose to ignore it, but doing so may affect consumers’ credit information and bring inconvenience to life and work.

　　In addition, from the consumer’s own point of view, staged consumption increases irrational consumption behavior. The amount of payment is reduced when the installment is consumed, which makes people have the illusion of spending less. The risk monitoring measures of many platforms are not in place, which may easily lead to credit problems such as overdue default by unqualified consumers.

　　How hard is it to choose?

　　By means of digital management and information sharing, we will strengthen the construction of credit system and prevent multi-head lending. Consumers should abandon vanity, comparison and blind obedience.

　　Behind the popularity of installment consumption, how can we rationally use and manage installment consumption?

　　Dong Ximiao believes that from the perspective of regulators, we should continue to carry out the special rectification of Internet finance and increase the cleaning and rectification of various stages of consumption platforms. For the platform with disorderly operation and chaotic management, if it fails to pass the filing in accordance with the regulations, measures should be taken to resolutely close it.

　　"At present, China’s credit information market still needs to be further improved, and the problem of long-term lending in the industry has not been completely solved. I believe that after the sharing of credit information data at the national level in the future, the whole industry will develop more healthily and orderly." Dong Ximiao said.

　　Credit data is an important link in risk control of phased consumption platform. Companies such as Taobao, JD.COM, Ctrip, etc., which have mastered the consumption scenes of hundreds of millions of users, have a large user base and many data resources, and can keenly capture the credit rating of users, and the cost of risk control is low. It is difficult for other financial platforms to accurately judge consumers’ credit information "Facebook".

　　"Now, for installment consumption, we have to put a lot of energy into risk prevention and control. It can be said that if the risk control is done well, the operating cost will be reduced, and the platform installment consumption interest rate will be reduced accordingly, thus attracting more quality customers." Gao Sheng, the public relations director of Staged Music Mall, said, "For example, we are now using artificial intelligence technology to develop ‘ Hawkeye ’ The intelligent risk control engine has more than 6,000 risk control model data variables, which can greatly improve the efficiency of risk control audit. "

　　Dong Ximiao suggested strengthening the construction of credit infrastructure, consolidating and enriching the credit information system by means of digital management and information sharing, improving the risk identification ability and risk prevention efficiency of installment consumption business, and enabling institutions and customers to enjoy more convenience in inclusive finance.

　　Banks and internet platforms should further improve or establish their own risk assessment and monitoring systems, objectively evaluate users’ consumption levels, and reasonably set credit lines; Staging consumption business institutions and platforms should correctly carry out marketing propaganda, put an end to false propaganda and induced propaganda, and set up necessary punishment mechanisms.

　　For consumers, we should carefully choose between bank credit card and installment payment platform, and try to choose a bank credit card with a more formal and perfect management system. If you choose the internet installment consumption platform, you should carefully check how to calculate the installment consumption interest, handling fee and service fee to prevent being charged with high interest and service fee.

　　"Installment consumption is a form of prepayment. If the repayment is overdue, it will not only increase the overdue interest, but also affect their credit rating, and even some financial institutions will terminate the installment business." Dong Ximiao said that consumers should abandon the bad mentality of vanity, comparison and blind obedience, carefully weigh whether the purchase of goods is reasonable, and formulate reasonable consumption and repayment plans to avoid over-consumption and over-consumption.

　　The insiders believe that for platforms with relatively standardized operations, the principle of "same business, same supervision" should be adopted to implement penetrating supervision, safeguard the legitimate rights and interests of financial consumers and protect the security of personal information. At the same time, we will strengthen the monitoring of the installment business it provides in terms of loan purposes and capital flow. Consumers should also enhance their risk awareness, strengthen the study of financial consumption and network security knowledge, and not disclose personal information at will to improve their ability to identify and prevent bad businesses.

　　What are the installment consumption platforms? (link)

　　In the past two years, staged consumption platforms have mushroomed, with different application scenarios and different characteristics.

　　JD.COM White Strip: the first Internet consumer financial product in the industry. You can enjoy a deferred payment period of up to 30 days or a payment by installments of up to 24 days if you use white bars for payment on JD.COM website. In recent years, JD.COM White Bar has been integrated into more consumption scenes, gradually covering the fields of renting, tourism, decoration, education, wedding and so on, extending from credit purchase service to providing credit consumption loans to provide credit consumption services for more consumers.

　　Ant Flower Garden: Born in the e-commerce department, it mainly supports multi-scene shopping. Its main application scenarios are Taobao and Tmall. Recently, it has also settled in most e-commerce shopping platforms, such as Amazon, Suning and local life service websites, such as word of mouth, Meituan, public comment, etc., and also involved some overseas shopping websites.

　　Staging music: Staging music in the staged shopping mall under Lexin Group is a new consumption platform of "e-commerce+finance". The shopping mall consumption scene involves 3C digital, outdoor sports, beauty care, eating, drinking and having fun, etc. It is the official authorized distributor of Apple mobile phones. The platform provides phased consumption services for mainstream consumer groups such as young people and white-collar workers.

　　Consumer finance company: it is a non-bank financial institution that provides unsecured and unsecured consumer loans. According to the "2017 Internet Consumer Finance Development Report and Outlook" by Suning Financial Research Institute, there are currently 22 licensed consumer finance companies in China, of which banks account for more than 90%. Consumer finance companies have offline channels, and offline outlets basically involve the whole country. Many licensed financial consumer companies have launched in-store consumption business to expand the financial consumer market. With the development of internet finance in recent years, many consumer finance companies have begun to cooperate with e-commerce platforms to develop online consumer credit business.
