CCTV News:Today is "national love teeth day". According to the results of the third national oral epidemiological survey, more than 85% of adults in China suffer from periodontal diseases, which are closely related to the health of other organs in the whole body.

　　Periodontal diseases are related to organ health.

　　Periodontal diseases mainly include gingivitis and periodontitis. It is a common oral disease that gingiva and tissues around teeth are inflamed and destroyed under the action of dental plaque, which leads to tooth loosening and falling off.

　　The oral cavity is the entrance of respiratory tract and digestive tract. Periodontal diseases not only harm the oral cavity, but also are closely related to the whole health. When periodontal diseases occur, a large number of bacteria gather on the tooth surface and periodontal area, forming erosive ulcer surface. When a large number of bacteria accumulate on the ulcerated surface, daily chewing activities can make bacteria and toxic products enter the blood circulation, increasing the risk of systemic diseases.

　　Luan Qingxian, director of the Department of Periodontology at Peking University Stomatological Hospital, pointed out that periodontal diseases are linked to the heart, the brain, the lungs, the stomach and the next generation. For example, research now believes that if there are inflammatory factors in the blood, it will increase the prevalence of diabetes. Other studies have shown that the prevalence of cardiovascular and cerebrovascular diseases in patients with periodontal diseases will also increase.

　　Prevention of periodontal diseases and avoidance of obsolescence

　　The tooth loss rate of the elderly aged 65 to 74 in China is as high as 86%, while 10% of the elderly have no teeth at all. Experts remind that missing teeth will add a lot of burden to the digestive system and cannot be underestimated.

　　Tooth loosening is a slow process of physiological change, and the most effective way to avoid tooth loss is to prevent periodontal disease. Symptoms of periodontal disease include gingival bleeding, gingival swelling, pain, etc., which can cause teeth to loosen or even fall off in severe cases. Plaque and tartar are the chief culprit of periodontal disease, and adults should wash their teeth once a year.

　　Some people say that it is a natural law for people to lose their teeth when they are old, and there is no need to repair them. The doctor reminded that if the teeth are missing, the balance of the whole mouth will be disturbed. If not repaired in time, the rest of the teeth will be tilted, displaced and periodontal damage will be caused.

　　Children and pregnant women should pay special attention to oral health.

　　Special attention should be paid to the oral health of children and pregnant women. Children’s oral examination should start within 6 months after the first deciduous tooth erupts, once every six months. The oral health of pregnant women is not only related to their own health, but also affects the health of the fetus, which may lead to premature delivery and low birth weight infants. Moreover, during pregnancy, due to factors such as hormonal changes in the body and decreased immunity, pregnant women are particularly prone to cause dental and gingival lesions.

　　Small floss is a good helper for tooth cleaning.

　　A large number of studies have confirmed that although periodontal disease is the most prevalent oral disease, it can be prevented and cured. In addition to brushing our teeth on weekdays, there is also a small tool that can help us clean the plaque between our teeth, and that is dental floss.

　　The doctor said that brushing teeth with a toothbrush can only clean 70% of teeth, and the other 30% is the gap between teeth. Many oral diseases are caused by the uncleanness of the gap between teeth. Flossing can effectively remove residual food, soft tartar and clean dental plaque.

　　How to use dental floss stick correctly?

　　For patients who floss for the first time, a dental floss stick is a good choice. When you use the dental floss stick, the dental floss is directed at the gap between teeth, and gently slides the gap between teeth by horizontal pulling and oblique pulling, so that the dental floss is "C"-shaped, and then it is pulled up and down for four to six times, and then the other side, which is also the "C"-shaped, is cleaned, and then it is pulled up and down for four to six times, and finally the dental floss is slowly pulled out from the gap.

　　Experts emphasize that dental floss cannot be reused. Some friends reuse the same dental floss for convenience, which is very undesirable. Because dental floss will carry a lot of germs after cleaning teeth, and these germs can’t be washed clean with water. Frequent use may bring more bacteria to teeth, so be sure to pay attention!

　　There is no harm in using dental floss. As long as you master the correct use method, don’t use too much force to avoid damaging your gums, you can floss once or twice a day.

　　Can you really brush your teeth?

　　Do you want to brush your teeth if it bleeds? Can soft bristles brush away dirt from teeth? Xiaobian combed the eight misunderstandings about brushing your teeth and poked pictures to learn how to brush your teeth correctly!

　

　

　

　

　

　

　

Guangzhou Winter Solstice New Year’s Eve Food Celebration Reunion At 5: 48: 01 on December 22, 2022, the winter solstice, the shortest day and the longest night, will be ushered in again. During the Zhou Dynasty, the month of the winter solstice was the first month. In the Han Dynasty, the winter solstice was called "Winter Festival". From the Han Dynasty to the Qing Dynasty, the winter solstice was "as big as a year" or "as inferior as a year". The custom of celebrating the winter solstice has influenced to this day. People in Guangzhou celebrate the Winter Solstice with great solemnity, which is known as "the Winter Solstice is a big New Year" and "the fat winter is a thin year". How time flies, no matter how the times change and the weather changes, Guangzhou people spend the winter solstice with a sense of ceremony: the ancestor worship, the sweet and delicious glutinous rice balls, and the steaming stove are all warm and reunion memories written by Guangzhou people. Tracing back to the history of "Winter Solstice", "Winter Solstice" is indeed true in history. Because "year" is the product of calendar, only when the calendar is made can the year be calculated. To calculate the calendar of a year, we must first set a starting point for calculation, called epoch. Legend has it that the Yellow Emperor ordered people to observe the movement of the sun, the moon and the stars, and made the first calendar in China, Huangdi Calendar, with the winter solstice of Jiazi on the eleventh lunar month as the yuan day. From this perspective, there is a winter solstice and then a year, so "the winter solstice is a big New Year". In the Yellow Emperor, November of the lunar calendar was the first month, and the winter solstice was the beginning of the year. The winter solstice was equal to the Chinese New Year. "New Year in Winter", a family dinner with a traditional sense of ceremony, entrusted a beautiful vision of family reunion. During the nearly 800 years of the Zhou Dynasty,The weekly calendar also takes November of the lunar calendar where the winter solstice is located as the first month, and the winter solstice is very grand. "Zhouyi" says: "The first king and even the Japanese closed their doors, and business travel was not good, and they were not provincial." That is to say, during the Zhou Dynasty, on the winter solstice, the frontier fortress was closed, officials did not work, businessmen did not do business, and everyone had a holiday. Secondly, the winter solstice is a solar term, and the 24 solar terms are part of the solar calendar in the lunar calendar, which was originally obtained by the method of "vertical pole surveying", based on the sun. The "year" is derived from the lunar calendar in the lunar calendar, and the first day of the first month of each year is determined according to the cycle of the moon orbiting the earth. The sun is sunny and the moon is cloudy, which can be understood as "the winter solstice is a big New Year". On the winter solstice, the day is the shortest and the night is the longest in the northern hemisphere. In the eyes of the ancients, the winter solstice is the starting point of the transformation of Yin and Yang. After the winter solstice, the days will get longer and the yang will rise, which is a new beginning. This is an important day when the cathode reaches, and the yang will begin to grow. Therefore, Hanshu said: "The sun is the spirit on the winter solstice, and the monarch is long, so congratulations. On the summer solstice, the yin qi rises and the monarch disappears, so I don’t congratulate you. " It is considered that the winter solstice is an auspicious day and should be celebrated. Festivals The Winter Solstice in the Han Dynasty is called the "Winter Festival", and the Tang and Song Dynasties have a seven-day holiday, which is like the Chinese New Year. Now, on this day of the Winter Solstice every year, the online "North-South dispute" begins: Do you want to eat glutinous rice balls or jiaozi? In fact, Chinese’s winter solstice is not just about eating and drinking. The winter solstice has a long history from solar terms to Chinese festivals. In the first year of Emperor Wudi of the Han Dynasty (104 BC), taichu calendar was used, and the first month was designated as the beginning of the year, separating the first month from the winter solstice.But the custom of He Dong still follows. In the Han Dynasty, the winter solstice was called the "Winter Festival". The custom of festivals is similar to that of the Zhou Dynasty. In addition to offering sacrifices to heaven and having holidays, there are also "winter worship" and "winter greetings". "History of Etiquette in the Later Han Dynasty" records: "Before and after the Winter Solstice, a gentleman lived quietly, refused to listen to politics, chose auspicious days and then saved trouble." It can be seen that around the winter solstice in the Han Dynasty, the imperial court stopped government affairs and concentrated on "He Dong". From the Han Dynasty to the late Qing Dynasty, the winter solstice was "as big as the year" or "as small as the year". During the Wei and Jin Dynasties, every winter solstice, the emperor was "congratulated by all nations and hundreds of people … and his appearance was inferior to that of the old dynasty." The solemnity of the "He Dong" ceremony is second only to the New Year celebration on the first day of the first month. Since then, the winter solstice has been known as the "Asian Year". The night before the first day of the first month is called New Year’s Eve, and the night before the winter solstice is called "winter removal". The "Golden Week" in the Tang Dynasty is the winter solstice and the Spring Festival. Emperor Xuanzong of the Tang Dynasty promulgated the national decree "False Ning Order", saying, "Yuan Zheng and Winter Solstice are given seven days off each." For the first time, it is stipulated that the "Winter Solstice Festival" holiday will be extended to seven days, which is also an important manifestation of the prosperity of the "Winter Solstice Festival". The Winter Solstice Festival in the Song Dynasty also had a seven-day holiday, "Winter Solstice is like Chinese New Year". "Dream of Tokyo" has such a record: "November winter solstice. The capital attaches the most importance to this festival. Although it reaches the poor, it is easier to get new clothes, prepare meals and enjoy the ancestors in a year. Officials let go and celebrate exchanges, just like the New Year Festival. " The Ming Dynasty’s "A Brief Introduction to the Scenery of the Imperial Capital" introduced the grand occasion of Beijing’s winter solstice at that time: on the winter solstice in November, a hundred officials of civil and military affairs, He Donghou, wore auspicious costumes for three consecutive days and worshipped each other with red notes, just like the New Year. During the Qing dynasty,The winter solstice is still very grand among the people. Qing Jia Lu is a monograph that systematically records the folk life in the south of the Yangtze River at the age of 18, in which it is written that "the county people attach the most importance to the winter solstice festival" and "the winter solstice is as big as a year." In 214 BC, Qin Shihuang ordered Ren Xiao and Zhao Tuo to unify Lingnan, saying that "books are the same, cars are on the same track, degrees are the same, lines are the same, and places are the same", and the winter solstice originated in the Central Plains took root in Lingnan. During the Tang, Song and Yuan Dynasties, along Zhuji Lane, people from the Central Plains moved into Guangfu several times on a large scale, and the custom of the winter solstice spread further, and it was very grand. In 1956, the report on the Winter Solstice published in Guangzhou Daily recorded that in the old days, Guangzhou people had a set of "rules" full of "Cantonese flavor" for celebrating the Winter Solstice: worshipping ancestors, eating glutinous rice, cooking glutinous rice with preserved meat, killing chickens and ducks and stewing eight treasures (referring to stewing eight rare and precious cooking materials, the specific meaning of which varies with the times and regions). According to the Collection of China Local Records and Folklore Data (Zhongnan Volume), almost all the "folk customs at the age of one year" in Guangdong local chronicles are written around the world to celebrate the winter solstice, and every family in Guangfu area regards it as as as big as a year. Different from the north, the weather in Guangfu is hot and humid in spring and summer, and warm in autumn and winter, and winter can only be truly felt until the winter solstice, so Lingnan people have taken the greatest enthusiasm to welcome the winter solstice: people who have been working in the four places have come home to reunite; The way of eating has also changed from the usual cooking mode of clearing away heat to "a side furnace", which has opened a rare opportunity to make up for winter. In ancient times, the winter solstice was an important day to worship the gods and ancestors.On this day, the emperor will hold a grand ceremony to worship heaven in the suburbs, and the common people will also worship their ancestors and pray for good weather in the coming year, and then sit around and eat, just like a New Year. Therefore, the winter solstice is also known as the "small year". Lingnan literature also talks about the tradition of the winter solstice, such as "Zengcheng County Records" (an increased edition in the tenth year of Tongzhi in the Qing Dynasty): "The winter solstice is a feast to worship ancestors"; "New Records of Conghua County" (the first year of Qing Xuantong): "On the winter solstice of the mid-winter month, families worship their ancestors and celebrate the lawsuit, such as the story of’ Yuanri’". The winter solstice in Guangzhou is very grand. "Huaxian County Records" (a block-printed edition in the 16th year of Guangxu reign in Qing Dynasty) said that "the winter solstice is celebrated by scholars and husbands. From the beginning of the day to the beginning of the day, the folk custom worships the ancestors and the Yanke, which is especially heavy than other festivals. It is called the group winter to offer a meal. " Nowadays, many older people in Guangzhou still regard ancestor worship on the winter solstice as the most important custom on this day. Cao Popo, who lives in Shabei Village, Baiyun District, has always followed the old ceremony. Every year before the winter solstice, she will buy shad in advance. "Marinate shad with salt, fry the shad skin until golden brown, seal it with plastic wrap and put it in a rice jar, which is called’ pressing winter’." On the day of the winter solstice, she will get up early to get fish, which means that there is more than enough money every year, and then put all the offerings such as roasted meat, winter oranges and glutinous rice balls in the hall to worship her ancestors. "In the past, the days were tight. After completing the ancestor worship ceremony, some of the offerings were robbed by the children to become breakfast and eaten into the stomach." Cao Popo said with a smile that life is getting better and better now, and grandchildren are no longer rare for offering sacrifices to their ancestors. The most important thing to spend the winter solstice is "group winter" (reunion). If the ancients did not reunite with their families on the winter solstice, they were often unhappy.Su Shi once wrote "A Lonely Visit to Jixiang Temple on the Winter Solstice Day": "The sunshine at the bottom of the well has not returned, and the rustling cold rain is wet and withered. Who is more like Master Su, not willing to come alone when he spends time? " Just four sentences, a total of 28 words, describe Su Shi’s inner helplessness. Although Su Shi wants to go back to his hometown to reunite with his family and spend the Winter Solstice Festival together, the real life makes him very helpless, so he has to go to Jixiang Temple alone to play. Sitting around "Tuandong", hot meals warm the stomach and heart. For Laoguang, in winter, glutinous rice balls and preserved glutinous rice are essential! "Every family makes glutinous rice balls, knowing that it is the winter solstice of the Ming Dynasty." According to legend, the original form of glutinous rice balls is a popular snack "Yuan (Yuan) Zi" in Song Dynasty, which is recorded in Dream of Tokyo. When the children finish eating a bowl of sweet glutinous dumplings, the mother often fills another bowl, saying that this is called "adding new year". The New Year has not passed, but it has grown up by one year! The round glutinous rice balls symbolize reunion and perfection, and also place a good vision for life in the coming year. According to a survey, people in Guangzhou love black sesame stuffing, glutinous rice balls stuffed with bean paste and peanut stuffing. Little one learns to make dumplings. Some families in Guangzhou will also specially cook glutinous rice with preserved meat. The ingredients of preserved glutinous rice are very rich, including mushrooms, shrimps, scallops, sausages and other ingredients. Waxy glutinous rice bears the imprint of family. When many people in Guangzhou were young, their elders made it for the holidays. Whenever a wanderer eats glutinous rice outside, he often thinks of a family sitting happily together and eating a bowl of warm waxy glutinous rice to drive away the cold.Talking about the time. Food evaluation Lao Yibo said, why do southerners eat more glutinous rice products during the winter solstice? He believes that, first, glutinous rice is sticky and has the meaning of "reunion" that tightly sticks the family; Moreover, glutinous rice has a high calorie, and eating a portion of glutinous rice in winter is more "hungry" than a bowl of rice. Pan Jianming, vice president of Guangdong Folk Culture Research Association, said that in Guangzhou 40 or 50 years ago, every household still needed to make their own small cakes by hand. Every winter solstice, zhu cun’s neighbors generally like to make meat buns, candy pills or powdered fruit. Eating nine baskets and sitting around the edge furnace is a reunion day on the winter solstice, and there is no shortage of reunion dinner. The winter solstice is difficult to attract the attention of modern people because there is no public holiday. However, in the evening, Cantonese people are still willing to get together and enjoy the reunion dinner. "In the past, most families chose to cook at home, but now they are more willing to go to restaurants for dinner, saving trouble." Feng Yi, who lives in Xihua Road, told reporters that the memory of her childhood winter solstice is inseparable from a reunion dinner. Usually, her mother cooks, kills chickens and geese in advance, buys roast meat, preserves shad, and adds fans, shrimp, fish eggs, mushrooms, radishes and other materials to make nine vegetarian dishes, and then puts them into the "octagonal bowl" with rooster patterns. "Nine dishes not only mean a long time, but also show the importance of festivals. Feng Yi said that the conditions were poor at that time, and there were usually nothing to eat, so everyone was particularly looking forward to the arrival of the winter solstice. "At the end of eating, even the stew in the bowl would be licked clean." But now, her family is used to eating the winter solstice reunion dinner in the restaurant, thinking it is worry-free and time-saving.In addition to the nine baskets, it is freezing in the winter solstice, and the edge furnace has become the best choice for Guangzhou to drive away the cold. In Guangzhou, the history of "edge furnace" goes back to ancient times. In fact, the history of edge-beating furnace in Lingnan has been nearly two thousand years. Various bronze dings were unearthed in the tomb of Nanyue King, including: Chinese bronze dings with short hoof feet, Yue bronze dings with flat straight feet, and Chu bronze dings with high hoof feet. The most noteworthy one is the Chinese bronze dings with the word "Fanyu". Every winter, the King of Nanyue can invite several courtiers to get together, enjoy singing and dancing bells and chimes, and enjoy various delicacies, and at the same time, don’t forget to have a few drinks with a rhinoceros horn-shaped jade cup. In the Qing Dynasty, Guangdong Tongzhi appeared: "Surround the stove on the winter solstice and eat it as a side stove." According to the explanation of "Guangzhou Benzi", eating hot pot and rinsing is like "beating", and because people are standing by the stove and eating food while rinsing, it is called "edge furnace". What ingredients do you use for the edge furnace? The food structure and eating style of Guangfu people who spend the winter solstice also have distinct regional characteristics. Because Guangfu area is surrounded by rivers and seas and rich in aquatic products, its food structure reflects the characteristics of products in large rivers and seas. Guangzhou people love to eat raw fish in winter. Qu Dajun mentioned in "Guangdong New Language": "Cantonese customs are fond of raw fish, with perch, silver carp, yellow croaker, silver carp, snow carp and bighead carp as the top priority." In the Qing Dynasty and the Republic of China, there were many "Zhuzhi Ci" related to Guangzhou fish, such as "The winter solstice fish is the same everywhere, and the fresh fish is exquisite. A cup of hot wine will cool you down, which is still a fad in the past. " Traditional raw fish mostly take pomfret as raw material. "slice" with a thin knifeSlices as thin as cicada’s wings and crystal clear are made into raw fish, which is eaten with various ingredients and sauces. In the early morning of the winter solstice, various residential areas in Guangzhou became lively, and every household bought fish and meat. On the night of the winter solstice, the weather is getting colder. In addition to raw fish, people in Guangzhou also like to "edge the stove". Shrimp, squid, pork liver, lettuce, chrysanthemum, spinach, etc., the meat is cut into pieces, and the fish is cut into two pieces that are connected like butterflies, which are put into the soup and eaten immediately. This method is called "crossing the river with sand". However, with the change of the times, everyone gradually realized that the risk of parasites eating raw fish was extremely high, so they changed to eating cooked food by the side stove. Guangzhou people especially like radishes on the winter solstice. As the saying goes, "Radish in winter solstice and ginger in summer solstice, eating at the right time is not painful", which means eating the right food in different seasons to achieve the purpose of health preservation. In winter, people are accustomed to tonic and do little exercise every day, so it is easy to generate heat and phlegm in the body. Eating radish can stop coughing, quench thirst and promote the qi of viscera, while eating ginger in summer can increase appetite and promote digestion. In ancient times, people didn’t have mobile phones, computers, entertainment, air conditioning and heating, but even if the weather is cold, they should live a good life. Going home to visit relatives, seeking roots and visiting friends and hiking to enjoy the scenery has become an important activity of the winter solstice. Guangzhou people have the custom of going to Luogang to enjoy the "snow" on the winter solstice since ancient times. Luogang Xiangxue, one of the eight scenic spots in Yangcheng, has presented a beautiful landscape of "Shili Meilin" for thousands of years and has become one of the resorts for Guangzhou people to punch cards in the winter solstice. According to records, the cultivation of green plums in Luogang area originated in the Song Dynasty.Because of its unique natural environment, it often blooms twice. In the 1950s and 1960s, Meiyuan stretched for dozens of miles, commonly known as "Shili Meilin". Before and after the winter solstice every year, plum blossoms are in full bloom everywhere, white and crystal clear, full of fragrance, and the wind pulls flowers and dances, not flying snow is better than flying snow. Nowadays, in addition to Luogang Xiangxue Park, there are many places to enjoy the "snow". Plum Valley in Baiyun Mountain has about 600 varieties of plum trees such as Meizhou Palace Powder and Chaotang Palace Powder. Every time plum blossoms are in full bloom, hundreds of plum blossoms compete to open; There are nearly 60 Bai Mei plants in the Four Gentlemen Garden of Baiyun Lake, and the rippling water is just a stone’s throw away, so the Meilin landscape near the lake is particularly elegant. Fat and thin in winter, dry and wet in winter, Guangfu people often say "fat and thin in winter", and winter is more abundant than Chinese New Year. In fact, the saying that fat winter is thin has appeared as early as the Song Dynasty. Song people attached great importance to the winter solstice, but why was it a fat winter and thin year? Jin Yingzhi’s historical notes of the Southern Song Dynasty, The Drunken Weng Tan Lu, are analyzed as follows: "The capital city (now Hangzhou) has three major festivals: cold food, winter solstice and New Year’s Day (now Spring Festival) … Therefore, many people ask about each other’s legacy (greet each other and visit each other), and they will not talk about it until they are old or have insufficient financial resources. There is a saying that’ fat winter is thin’. " It turns out that the festival is too close, spending too much money is limited, so we have to make a choice. However, it can be seen that people pay more attention to the winter solstice than to the Chinese New Year. There are also some sayings about the weather on the winter solstice, the most famous of which is "dry winter and wet year" and "wet winter and dry year", which means that it rains around the winter solstice, and it is often sunny during the Spring Festival, and vice versa. "dry winter and wet year"Is this statement true? Experts say it’s not absolute, it’s just a folk saying. There is no corresponding relationship between the sunny winter solstice and the rainy Spring Festival. Whether it rains during the Spring Festival is mainly determined by the weather system and atmospheric circulation before and after the Spring Festival. Inheriting the white-cut chicken dumplings, waxy glutinous rice, reunion in winter must be eaten for thousands of years. Although the traditional winter solstice custom of Guangzhou people may gradually disappear in the city, many families in Guangzhou still regard the winter solstice as a big festival. Spending a big Chinese New Year holiday in Guangzhou-the winter solstice, can fully prove that Guangzhou exists as a traditional and modern city with great tolerance. On the winter solstice, Guangzhou people who are born and raised often have a family dinner with a traditional sense of ceremony to pin their beautiful vision of family reunion and spend this wonderful and warm day; And many new "Hakkas" who come from all corners of the country to settle down in Guangzhou do as the Romans do. In addition to expressing their homesickness through food with hometown characteristics, they have gradually integrated into Guangzhou’s local flavor customs, and finally condensed into Guangzhou’s rich winter solstice eating customs over time. Winter solstice, revisiting the family holiday dinner ceremony and celebrating the winter solstice according to traditional customs is still the choice of most old people. Every winter solstice night, food critic Lao Yibo’s family must eat "Kaiping Tangyuan". He was born and raised in Guangzhou, but his hometown is Kaiping, Guangdong. Every winter solstice, his parents cooked a large pot of Kaiping glutinous rice balls for the whole family to enjoy. "It is in this way that parents pin their homesickness, and it is also in this way that we remember our ancestral home."Lao Yibo said. Kaiping glutinous rice balls are solid glutinous rice balls, which are only the size of an adult’s index finger. Because of their simple production, when they were young, they always participated in the "action" of rubbing glutinous rice balls together, and glutinous rice balls of different sizes, such as big beads and small beads, fell on the plate. This soup dumpling is the "protagonist" of their winter solstice reunion dinner that night, accompanied by a home-cooked boiled chicken and a plate of boiled shrimp. The soup base of glutinous rice balls is made by boiling chicken shells. Tangyuan is the staple food, and the soup is also rich with fried shad balls, dried pork, dried shrimps, mushrooms, shredded radish and other vegetables. On a cold winter night, a bowl of warm glutinous rice balls warms not only everyone’s stomach, but also the heart of every family member sitting around a table. Boiled chicken with nine famous dishes. Matthew, a media person, is also a native of Guangzhou. He regards the arrival of the winter solstice as one of the most important comforts all the year round, just like a person taking part in a marathon, which is the most important supply station before the end of the race. In his memory, the day of the winter solstice means the time for family reunion. One of the most important things for a housewife’s mother all the year round is to prepare dinner on the winter solstice. When mother is physically able to do housework, she starts to be busy inside and out the day before the winter solstice. In the early years, the economy was not affluent, and the family had a large population. It was not easy to prepare a winter solstice dinner, but even so, I would rather scrimp and save on weekdays, and I would like to prepare more abundantly on the winter solstice day. In the early morning, she will rush to the market to buy food, kill chickens and ducks, prepare dinner, and then everyone will sit around a table.Have a big meal. What impressed Matthew the most was not only the delicious food cooked by his mother, but also the winter solstice dumplings made by his mother, which were filled with shage, pork and shrimp and served with chicken soup, salty but not greasy and delicious. This day’s waxy glutinous rice is not only delicious, but also excellent in meaning. According to mom, glutinous rice means warmth, and it is warm from the beginning to the end of the year. My mother also presents her dried bacon to relatives and friends on the winter solstice. Guangdong-style beef bone beef offal pot, take a bite for the winter, it’s really delicious. The ritual feeling of the full dinner on the winter solstice also made Matthew memorable: Mom is very traditional. Before meals, the family should worship their ancestors first, and they are not allowed to move chopsticks until everyone is here, otherwise they will have to wait even if they wait. The custom of "wintering" continues among the new generation. For Xiao Zhang, a new Guangzhou native born in 1990s, Guangzhou’s strong custom of celebrating the winter solstice has awakened childhood memories and deepened his understanding and recognition of China culture. He told reporters that in Guangdong, where traditional culture is well preserved, the winter solstice is a lively and extraordinary festival, which makes people feel warm and comforted. The winter solstice is regarded as the "sub-year-old" after the New Year. It is not only the end of a year, but also the beginning of a new year. It is a day of family reunion and happiness. Looking back on the winter solstice when I was a child, a few days before the festival, my parents had begun to prepare all kinds of ingredients for the festival, such as mutton, beef and chicken … On the winter solstice, I would see a table full of delicious food, and the whole family would gather around the table to drink, warm up, eat delicious food and chat at home. On the morning of the winter solstice, my mother will wake me up from the bed."The dumplings I cooked are cold, so don’t get up quickly." Listening to my mother’s nagging, eating round glutinous rice balls, which is the warmth of home alone. Have a bowl of warm glutinous rice balls. Miss a bowl of hot glutinous rice balls in the morning of the winter solstice, miss the reunion dinner at night of the winter solstice, miss the tender and meticulous care of parents … This winter solstice, Xiao Zhang decided to go home for the holiday, "Winter solstice is a big New Year", don’t eat dinner alone, it’s better to go home! Have a happy reunion dinner with my family on the night of the winter solstice. It is a day of family reunion to let the traditional winter solstice custom return to the winter solstice rationally. With the improvement of people’s living standards, it has long been the choice of many families in Guangzhou to have a reunion dinner in restaurants. Many people in Guangzhou began to choose restaurants to celebrate the holidays and have family reunion, so that all restaurants, large and small, were shocked (lively). Slowly, the winter solstice became one of the busiest festivals in Guangzhou restaurants in a year. After the winter solstice, the Spring Festival, when the whole family has dinner together, is approaching. In recent years, the developed take-out has promoted the dishes in the Winter Solstice restaurant to enter thousands of households. The complex and laborious "hard dishes" such as Buddha jumping over the wall and potted vegetables have met the needs of some citizens to "eat at home". Gum, abalone, sea cucumber, duck’s feet, chicken wings, pig’s hands, blessing bags … They are soaked in abalone juice, and the rich sauce is boiling in the furnace, and the rising fireworks surround the family, driving away the cold of winter nights. Compared with dishes that are cold as soon as they are put, it is more enjoyable to enjoy hot dishes while boiling. Guangdong-style mutton pot that has been passed down for five generations. This year, as the winter solstice approaches,Although it is still the choice of Guangzhou people to go to restaurants to order takeout for the winter solstice, many people plan to regain traditional customs and spend the winter solstice at home, which to some extent allows the traditional winter custom to return. Matthew is one of them. Now the brothers and sisters have already married separately, and the mother is old, and she can no longer cook and take charge of the kitchen utensils and prepare the winter solstice dinner for her family. Matthew intends to let the nanny who takes care of the elderly at home buy fresh chicken, duck and fish in the vegetable market on the winter solstice and bagged dumplings in the supermarket. Although for many people in Guangzhou, it is no longer a "standard" to eat glutinous rice balls on the winter solstice, what is needed is a sense of ceremony and a warm feeling of home. Affection and warmth are all in this hot glutinous rice ball. Guangzhou people spend the winter solstice in this way, which contains their love for life, their persistence in tradition and their great cherish for the change of years. The sky is dark and smoky, and the famous papers are handed down to celebrate the winter. Embroidered curtains are not rolled up, and it is easy to laugh and laugh. —— Yuan Ma Zhen, thousands of families have been singing for a long time, and they have traveled far and wide.

CCTV News:During the period of Spring Festival travel rush, the passenger flow of Shenzhen Railway maintained a high level and rose steadily, and the peak of passenger flow before the holiday was coming. In order to meet the travel needs of passengers, since February 3, Shenzhen Railway Department has successively opened several high-speed trains at night.

At 00: 10am on February 3rd, the first night high-speed train G4598 from Spring Festival travel rush in Shenzhen in 2024 departed from Shenzhen North Station and ended at Wuzhou South Station. More than 1,000 passengers took this high-speed train to go home.

In Spring Festival travel rush in 2024, according to the pre-sale of tickets and the standby ticket purchase of 12306, the Shenzhen Railway Department increased the capacity in popular directions. On February 3-4 and 6-9, 48 night high-speed trains were added from Shenzhen North Station to Chengdu, Guiyang, Nanchang, Changsha South, Wuhan, Zhengzhou East, Zhanjiang and Chaoshan, and 6 night general-speed passenger trains were added from Shenzhen East Station and Shenzhen Station to Changsha and Yueyang.

During the night high-speed rail operation, Shenzhen Railway also contacted the local transportation department to connect with the surrounding public transportation service hours such as buses and subways, so as to realize the "zero-distance connection" for passengers to travel at night and ensure the "last mile" for passengers to travel.

Pre-holiday peak arrival "charging battery life" home road

In Spring Festival travel rush this year, there are many passengers traveling by car, which is the main artery of north-south traffic in China — — In the service area of Beijing-Hong Kong-Macao Expressway, the number of new energy vehicles charged these days is 10 times more than usual. Is the charging pile enough? What is the charging efficiency? The reporter came to the scene to find out.

CCTV reporter Chen Xi:I am now at the entrance of Baoding service area of Beijing-Hong Kong-Macao Expressway, about 150 kilometers south of Beijing. As you can see, these vehicles leave Beijing and arrive here in about 2 hours. They will refuel, eat and rest in the service area.

Facing the structural changes of self-driving travel, before Spring Festival travel rush this year, 12 high-power charging piles were built in Baoding service area ahead of schedule, and now 20 new energy vehicles can be charged at the same time. Near noon, more and more cars entered the service area. The reporter noticed that all charging piles in the service area were running at full load.

New energy owner Feng Wei:Hello, big brother, there are so many cars. When can I charge this car?

Hebei Baoding service area staff:Don’t worry, we have already dispatched, and the mobile charging car will come soon.

Huo Guoqing, Marketing Manager of a New Energy Technology Company:Four cars can be guaranteed at a time, and more than 100 trains a day (one charging car can charge), and the fixed piles here can basically meet the use of Baoding service area.

The reason why the mobile charging car can be dispatched in time is because there is a "smart brain" behind it. There are seven service areas along the Beijing-Hong Kong-Macao Expressway. The "small dispatch" can dispatch the charging piles in each service area, while the smart dispatch center 100 kilometers away connects the seven scattered service areas into a "line" through the "big dispatch" to co-ordinate all 84 charging piles and 3 mobile charging vehicles on the whole expressway.

During the period of Spring Festival travel rush, the number of new energy vehicles traveling on expressways in Hebei Province is expected to reach about 3.5 million, and the charging pressure is huge. In addition to the "on-demand charging" charging method of charging piles, Hebei Province has also added 50 power stations, with a total of 65. The reporter saw at the scene that it only takes 3 minutes for the new energy vehicle to change the battery, and the replaced battery is left in the power station for charging, and the owner behind can recycle it.

New energy owner Zhou Yadong:There are still about nine hours to go to Xi ‘an, about once every 200 kilometers (battery) and four times (battery to Xi ‘an). It is more convenient to change electricity all the way through our route.

In order to cope with the large passenger flow in Spring Festival travel rush this year, the Hebei Provincial Department of Transportation built 293 highway charging piles in 2023, with a total of 962; 50 new power stations have been added, which is more than three times higher than before, fully ensuring the "rechargeable battery life" on Spring Festival travel rush Road.

　　A few days ago, with the optimization and adjustment of national epidemic prevention and control measures, Jiangsu, Zhejiang, Sichuan, Guangdong, Fujian and other places began to organize business charter flights for foreign trade enterprises to attract investment overseas.

　　Suzhou, the first city to take action, has already got back 1.86 billion US dollars of intended investment from Japanese companies and won over 1 billion yuan of foreign trade orders in the first round of investment delegation to Japan. In the early morning of December 9, Suzhou once again organized a charter flight to Europe. At the same time, Hainan Province, led by Hainan International Economic Development Bureau, sent the first overseas investment delegation to Japan to carry out in-depth investment promotion activities. Jiangxi Province, hosted by the Department of Commerce and co-organized by the Jiangxi General Chamber of Commerce in Japan, held the "Online Promotion Conference of Overseas Investment Promotion in Jiangxi Province (Tokyo, Japan)" to discuss cooperation through Internet connection. On December 9th, Hunan Merchants Group also set off for Africa … … Fighting for the economy and grabbing orders has become a concerted action in various places, and it is expected that more provinces and cities will join.

　　Bai Ming, deputy director of the International Market Research Institute of the Research Institute of the Ministry of Commerce, said in an interview with the Red Star journalist that it is in line with the overall situation of stabilizing foreign trade for local organizations to invest abroad. Lack of orders is the pressure that foreign trade is facing at present. It is only one way to grab orders through government charter flights, but it is not a normal measure. He believes that the results of this batch of orders will be reflected in the economic data at the beginning of next year.

　　↑ Jiaxing, Zhejiang organized a charter flight to Japan to grab orders.

　　Many provinces and cities organized groups to grab orders abroad.

　　Going to Japan and Europe is the mainstream, and Africa has also become a destination.

　　On December 7th, according to the WeChat official account news of "Jiangsu Publishing" WeChat, from November 17th to 23rd, Suzhou Municipal Bureau of Commerce organized a charter flight service to Japan, which became the first charter flight service organized by a large-scale economic and trade delegation at the local government level since the epidemic in 2020. The trip to Japan was fruitful and won more than 1 billion yuan in new orders.

　　It is understood that this charter flight consists of 12 investment teams and 51 heads of foreign trade enterprises, with a total of 88 people. In just seven days, all investment teams visited 62 enterprises and relevant institutions, held three exchange and promotion meetings, and reached 32 investment intention projects with an intentional investment of 1.86 billion US dollars. Foreign trade enterprises actively expand the market and grab orders, visiting more than 200 Japanese customers, and striving for new orders exceeding RMB 1 billion. Charter service further consolidates and improves the level of Suzhou’s economic and trade cooperation with Japan, and strives for more orders and market share. From 9 to 18 December, Suzhou Municipal Bureau of Commerce also organized charter flights to France and Germany.

　　At 1 am on the 9th, Suzhou organized a charter flight to Europe again.

　　"This time, the charter flight time was specially put at 1 am, so it was 6: 45 local time to arrive in France, and you can visit customers immediately after landing." Sun Jianjiang, director of Suzhou Municipal Bureau of Commerce, said in an interview with Xinhua Newspaper Intersection that he had arranged to visit four customers on the first day, including two Fortune 500 enterprises, financial institutions and business associations. In an interview, Sun Jianjiang also said that in Europe, there were only 10 days, more than 230 events were arranged, and the heads of global industry heads were visited every day. In order to have a good harvest and attract more and better foreign investment projects to Suzhou, they feel it is very worthwhile.

　　According to Zhejiang Daily, on December 5, all 11 districts and cities in Zhejiang Province optimized and adjusted the policies and measures for epidemic prevention and control, and at the same time, almost simultaneously promoted the action of "thousands of enterprises expand the market to grab orders" to stabilize the economy. This is a collective action and team battle led by the Zhejiang Provincial Department of Commerce and led by commercial departments all over the province to lead foreign trade enterprises to find markets and grab orders. It is estimated that 1,000 delegations and about 10,000 foreign trade enterprises will participate. On December 4th, the business charter organized by Jiaxing City set sail from Hangzhou Xiaoshan Airport to Tokyo, Japan, and held a seven-day business activity from December 4th to 10th, attending the AFF exhibition in Japan, conducting business visits, inspection and investment promotion activities. There are 50 companies, with a total of 96 people, including 8 merchants. It is the largest foreign trade charter delegation at the municipal level this year. On the same day, the main leaders of Jiaxing Municipal Bureau of Commerce also led a team to Germany and France to launch a six-day European investment promotion trip.

　　According to the news of the Sichuan Provincial Department of Commerce, on December 5th, "Sichuan foreign trade enterprises’ business charter flights to Europe to expand the international market" set sail in Chengdu. Forty people from 31 foreign trade enterprises in Sichuan food, medicine, automobile, furniture, agricultural products and other industries will fly to France, Germany and Italy to carry out 9-day economic and trade promotion activities. By visiting new and old customers, attending famous exhibitions, investigating local business associations and business enterprises, they will deepen their cooperation intentions, grasp the dynamic trends of the industry and investment environment policies, and expand economic and trade exchanges.

　　According to Changsha Evening News and New Hunan, on December 9, the economic and trade delegation of Hunan Provincial Department of Commerce will visit Mozambique, Tanzania and Madagascar, aiming at promoting and inviting them to participate in the third China-Africa Economic and Trade Expo, and will visit nearly 10 departments of industry, trade, agriculture and energy in the three countries, conduct on-the-spot investigation and research on 9 key projects and parks of cooperation with Africa, and hold a series of economic and trade docking and exchange and negotiation activities. On December 11th, Hunan Provincial Department of Commerce will send a team to Singapore to meet Singapore’s economic and trade development and cooperation opportunities, establish a communication mechanism, and tap the potential of economic and trade exchanges and cooperation between the two sides.

　　↑ Zhejiang Ningbo delegation went to Europe to "grab orders" according to People’s Daily Online.

　　Expert analysis:

　　The results of grabbing orders will be reflected in the economic data early next year.

　　A person from a foreign trade enterprise in a city in Shandong told the Red Star journalist that although his city did not propose charter flights to take foreign trade enterprises abroad to attract investment, the registered enterprises can reimburse the air ticket expenses, and many enterprises have signed up.

　　A staff member of Suzhou Bureau of Commerce told Red Star News reporter that at present, Suzhou has only arranged two batches of investment promotion to Japan and Europe. This is not a normalization measure. Whether to continue to carry out it in the future, I hope that enterprises will pay attention to the information of business departments in various districts and counties.

　　A staff member of Hainan International Economic Development Bureau said that Hainan recently organized an investment delegation to Japan, mainly composed of government workers, with the purpose of helping Hainan enterprises go global by visiting Japanese enterprises. At present, we are also studying plans to help enterprises go abroad, such as charter flights, and we are also studying investment promotion activities in other countries. If relevant activities are really launched, they will be sent out through official channels to invite enterprises to pay attention.

　　Bai Ming, deputy director of the International Market Research Institute of the Research Institute of the Ministry of Commerce, said in an interview with Red Star News that the state supports and encourages foreign trade enterprises to go abroad. Some time ago, foreign trade was under great pressure, and the government’s organization of foreign investment was in line with the overall situation of stabilizing foreign trade. On the other hand, China’s epidemic prevention and control measures are more optimized. The "Twenty Articles" and "New Ten Articles" have new requirements for aviation and entry and exit, and also created conditions for government charter flights.

　　Bai Ming said that the lack of orders is the pressure on foreign trade at present. It is only one way to grab orders through government charter flights, but this is not a normal measure. With the stable epidemic situation and the resumption of various routes, enterprises may not need to wait for government charter flights. It is impossible for government charter flights to reach every place, and the time may not meet the requirements of every enterprise. With the recovery of more routes, enterprises themselves should actively go out. He believes that the results of this batch of orders will be reflected in the economic data at the beginning of next year.

　　Bai Ming believes that different types of enterprises should find their most suitable way. Some enterprises have long-term overseas customers and do not need to rely on government charter flights. Some enterprises can find good local agents and rely on overseas institutions or local agents to play their role. We should also make full use of cross-border e-commerce and other channels.

　　Deeply understand and accelerate the development of new quality productive forces

　　Commentator of Qiushi magazine

　　"Developing new-quality productive forces is an inherent requirement and an important focus for promoting high-quality development. We must continue to do a good job in innovation and promote the accelerated development of new-quality productive forces."

　　On January 31, 2024, General Secretary of the Supreme Leader delivered an important speech when he presided over the 11th collective study in the Political Bureau of the Central Committee, systematically expounded the scientific connotation of new quality productivity from the combination of theory and practice, profoundly pointed out the great significance of developing new quality productivity, and put forward clear requirements for developing new quality productivity. From putting forward "new quality productive forces" during a local inspection in 2023, to emphasizing "developing new quality productive forces" at the Central Economic Work Conference, and then making a systematic exposition during the collective study of the Politburo, the General Secretary’s series of important expositions and major arrangements on developing new quality productive forces have profoundly answered the important theoretical and practical questions of "what is new quality productive forces, why should we develop new quality productive forces, and how to develop new quality productive forces", which provides a basis for promoting high-quality development in the new journey.

　　High-quality development needs the guidance of new productivity theory.

　　Marxism holds that productivity is the material premise of all social life, the most active and revolutionary factor to promote social progress, and the productivity standard is a fundamental standard to measure social development. Marx and Engels pointed out that "the sum of people’s productive forces determines the social situation". Unswervingly promoting the development of productive forces and constantly improving people’s living standards on this basis is the fundamental starting point of all our party’s work.

　　The fundamental task of socialism is to liberate and develop social productive forces, and the superiority of socialism over capitalism lies in its ability to develop productive forces faster and better. After the founding of New China, Comrade Mao Zedong proposed that "the purpose of socialist revolution is to liberate productive forces". After the reform and opening up, Comrade Deng Xiaoping clearly pointed out that "there are many tasks of socialism, but the fundamental one is to develop productive forces". Since the founding of the People’s Republic of China, our Party has only spent several decades leading the people to complete the industrialization process that developed countries have gone through for hundreds of years, promoting China’s development into the second largest economy in the world, and creating a miracle of rapid economic development that is rare in the world. It is extremely important to attach great importance to productivity standards, always adhere to the liberation and development of social productivity, and constantly enhance the comprehensive national strength of socialist countries.

　　Entering a new era, China’s economic development has entered a new stage. The CPC Central Committee with the Supreme Leader as the core regards adhering to high-quality development as the last word in the new era, consistently liberates and develops social productive forces, makes a series of major decisions and arrangements, and pushes China’s economy to a higher-quality, more efficient, fairer, more sustainable and safer development path. The level of productive forces has achieved great improvement and breakthrough development, forming a new qualitative state of productive forces development. In view of this new situation, the General Secretary of the Supreme Leader clearly pointed out that "the new quality productivity has been formed in practice and has shown a strong driving force and support for high-quality development".

　　At the same time, we should also see that there are still a lot of factors restricting high-quality development, such as some key core technologies being controlled by people, the problems of "big but not strong" and "all but not excellent" in the industry, and the pressure of transforming the production and living system to green and low carbon, and so on. To further promote high-quality development, we must form new industries, new models and new kinetic energy, firmly grasp key core technologies in our own hands, build a modern industrial system that is self-controllable, safe, reliable and competitive, build a green and low-carbon circular economy system, and realize connotative growth driven by innovation. In the final analysis, it is to achieve greater breakthroughs and greater development at the level of productivity. This puts forward a new topic for our theoretical development, and we need to further deepen our understanding of the new quality productivity. General Secretary of the Supreme Leader emphasized that the development of new quality productive forces "requires us to summarize and generalize theoretically to guide new development practice". General Secretary Supreme Leader’s important exposition on developing new-quality productive forces points out the important focus of promoting high-quality development, embodies a profound grasp of the development law of productive forces and the outstanding problems facing China’s development, and is a profound summary of the law of China’s economic construction, further innovating and developing Marxist productive forces theory, which is an important part of Supreme Leader’s economic thought and has important theoretical and practical significance. We must study deeply and deeply understand it and use it to guide practice.

　　Grasping the scientific connotation of new quality productivity

　　What is new quality productivity? General Secretary of the Supreme Leader pointed out: "In a nutshell, the new quality productivity is an advanced productivity that plays a leading role in innovation, gets rid of the traditional economic growth mode and productivity development path, has the characteristics of high technology, high efficiency and high quality, and conforms to the new development concept. It was born out of revolutionary breakthrough in technology, innovative allocation of production factors, and deep transformation and upgrading of industries. The basic connotation is the leap of laborers, labor materials, labor objects and their optimized combinations, and the core symbol is the substantial improvement of total factor productivity. Its characteristics are innovation, the key is high quality, and the essence is advanced productivity. " This important exposition profoundly points out the basic theoretical issues such as the characteristics, basic connotations, core symbols, characteristics, keys and essence of the new-quality productive forces, and provides a fundamental basis for us to accurately grasp the scientific connotation of the new-quality productive forces.

　　New-quality productivity is an advanced productivity with innovation as the leading role, and its characteristic is innovation. The key to grasping the new quality productivity lies in a deep understanding of the key role of innovation in improving productivity. Looking back at history, from the mechanization of the first industrial revolution in the 18th century to the electrification of the second industrial revolution in the 19th century, and then to the informationization of the third industrial revolution in the 20th century, subversive scientific and technological innovations have brought about great liberation of social productive forces and great leap in living standards, which fundamentally changed the development track of human history. Some countries have seized the rare opportunity of scientific and technological revolution and industrial transformation, and their comprehensive national strength has increased rapidly, even becoming a world power. At present, a new round of scientific and technological revolution and industrial transformation is ready to go, and some major disruptive technological innovations are creating new industries and new formats. Information technology, biotechnology, manufacturing technology, new material technology and new energy technology have penetrated into almost all fields, which has led to major group technological changes characterized by green, intelligence and ubiquity. We have ushered in the historic intersection of the new round of scientific and technological revolution and industrial transformation in the world and the transformation of development mode in China, and are faced with a once-in-a-lifetime historical opportunity. New quality productive forces have emerged as the times require and have continued to grow and develop in practice. New quality productivity represents the new direction and trend of scientific and technological revolution and industrial transformation, and represents the development direction of advanced productivity. To accelerate the formation of new quality productive forces is to gain a leading position in the development of productive forces, take the lead in new fields and new tracks, and win the initiative in development in fierce international competition.

　　Marx pointed out that "productivity, that is, the development of production capacity and its elements" and "labor productivity is developing with the continuous progress of science and technology". New quality productivity is the product of productivity development and scientific and technological progress, and it is a revolutionary promotion of human ability to transform nature. This promotion is holistic and fundamental, and as its constituent elements, workers, labor materials and labor objects must also have new connotations. As far as workers are concerned, workers are the most active factor in productivity. What matches the new quality productivity is no longer ordinary workers who focus on simple repetitive work, but strategic talents who can create new quality productivity and applied talents who can master new quality production materials skillfully. As far as labor materials are concerned, as a "measuring instrument for the development of human labor force", with the development and wide application of original technology and subversive technology, more and more new production tools will be produced, and old and backward production tools will be gradually replaced by new and advanced production tools, which is also the main symbol of the development of productive forces. As far as the object of labor is concerned, the improvement and extensive use of labor materials will inevitably lead to the expansion of the scope of labor objects, including not only traditional natural materials, but also intangible forms such as data that are not limited by space and time.

　　Only by combining various factors of production can we form realistic productive forces. New quality productivity is not only reflected in the innovative development of various factors, but also in the innovative development of the combination of production factors. With the development and changes of laborers, labor materials and labor objects in the new quality productivity, the optimized combination of the three will also undergo revolutionary changes, bringing new industries, new formats and new models, and forming new kinetic energy and new advantages that drive economic development. Productivity determines production relations, and production relations react on productivity. The formation of new quality productive forces will inevitably lead to revolutionary changes in production relations, and it is necessary to form new production relations to adapt to them, and protect, liberate and develop them. Constantly reforming and perfecting the relations of production and forming new management modes and new institutional mechanisms are important guarantees for promoting the continuous development of new quality productive forces.

　　In a word, we should deeply realize that the new quality productivity is not the local optimization and simple iteration of the traditional productivity, but the advanced productivity, which is spawned by the revolutionary breakthrough of technology, the innovative allocation of production factors and the deep transformation and upgrading of industries. It will certainly bring about changes in the development mode and production mode, promote the new leap of China’s social productivity and lay a more solid material and technological foundation for building a socialist modern country in an all-round way.

　　Promote new quality productivity and accelerate development.

　　"We can’t fall behind on the new track", "We should catch up, strive to achieve, run and even lead". At the Central Economic Work Conference in 2023, the words of the Supreme Leader General Secretary were inspiring. On the new journey of building a strong country and national rejuvenation, the most fundamental thing to promote Chinese modernization is to realize the modernization of productive forces. The essence of new quality productivity is advanced productivity. It is necessary to unify thoughts and actions with the spirit of the important speech of the Supreme Leader General Secretary and the decision-making arrangements of the CPC Central Committee, focus on the central task of economic construction and the primary task of high-quality development, further enhance the consciousness and initiative of promoting the development of new-quality productive forces, and improve the practical skills of promoting the development of new-quality productive forces.

　　— — Accelerate scientific and technological innovation. Scientific and technological innovation can give birth to new industries, new models and new kinetic energy, which is the core element of developing new quality productivity. We must strengthen scientific and technological innovation, especially original and subversive scientific and technological innovation, accelerate the realization of high-level scientific and technological self-reliance, lay a solid battle for key core technologies, and cultivate new kinetic energy for developing new quality productive forces.

　　— — Accelerate industrial innovation. Industry is the carrier of productive forces, and scientific and technological achievements can only become social productive forces through industrialization. It is necessary to apply scientific and technological innovations to specific industries and industrial chains in a timely manner, transform and upgrade traditional industries, cultivate and expand emerging industries, lay out and build future industries, and improve the modern industrial system. Layout the industrial chain around the development of new quality productivity, improve the resilience and safety level of the industrial chain supply chain, and ensure that the industrial system is self-controllable, safe and reliable.

　　— — Accelerate the innovation of development mode. Green development is the background of high-quality development, and new quality productivity itself is green productivity. We must speed up the green transformation of development mode, firmly establish and practice Lucid waters and lush mountains are invaluable assets’s concept, unswervingly take the road of ecological priority and green development, and vigorously advocate a green and healthy lifestyle in the whole society.

　　— — Accelerate the innovation of system and mechanism. The relations of production must meet the requirements of the development of productive forces. To develop new quality productive forces, we must further deepen the reform in an all-round way and form a new type of production relationship that is suitable for it. It is necessary to deepen the reform of the economic system and the scientific and technological system, and strive to get through the blocking points that constrain the development of new quality productive forces. Expand high-level opening to the outside world and create a good international environment for the development of new quality productive forces.

　　— — Accelerate the innovation of talent work mechanism. Talent is the first resource, and the essence of innovation drive is talent drive. In the final analysis, the development of new quality productive forces depends on innovative talents. In accordance with the requirements of developing new quality productive forces, we should smooth the virtuous circle of education, science and technology and talents, and improve the working mechanism of talent training, introduction, use and rational flow. Improve the income distribution mechanism in which factors participate, and create a good atmosphere to encourage innovation and tolerate failure.

Since Kunqu Opera was selected into UNESCO’s "Representative Works of Oral and Intangible Heritage of Humanity" in 2001, the government-led protection of intangible heritage in China has gone through 17 years. Although China’s intangible cultural heritage protection has not been carried out for a long time from an international perspective, with the great attention of the CPC Central Committee and the State Council, and the joint efforts of cultural administrative departments at all levels and all walks of life, China’s intangible cultural heritage protection has made rapid progress and achieved fruitful results, which not only created a vivid situation for the inheritance and development of intangible cultural heritage in the contemporary era, but also provided many methods and measures for the international community with China experience.

Establish rules and regulations, and build an intangible cultural heritage protection system.

In order to comprehensively understand and master the species, quantity, distribution, survival and inheritance of intangible resources in various regions and ethnic groups, from 2005 to 2009, China launched the first nationwide survey of intangible resources, and the total number of intangible resources was nearly 870,000. On this basis, China has established a national, provincial, municipal and county-level intangible cultural heritage list system. Up to now, the State Council has approved and published 4 batches of 1,372 national representative projects, and 15,550 provincial and municipal representative projects have been approved and published by various provinces, autonomous regions and municipalities. The former Ministry of Culture identified 4 batches of 1,986 national representative inheritors, and 14,928 provincial and municipal representative inheritors were identified by all provinces, autonomous regions and municipalities. China has been selected into UNESCO’s list of intangible cultural heritage projects, reaching 39, ranking first in the world.

In 2011, China promulgated and implemented the Intangible Cultural Heritage Law of People’s Republic of China (PRC). The promulgation of this law is a milestone, which provides a solid legal guarantee for the protection of intangible cultural heritage in China. The former Ministry of Culture has successively issued regulations on the protection and management of non-legacy representative projects, the identification and management of representative inheritors, the management of special funds, and the construction and management of cultural and ecological protection zones. By the end of 2017, 26 provinces, autonomous regions and municipalities across the country had promulgated regulations on the protection of intangible assets.

With the deepening of understanding, China proposes to protect the intangible cultural heritage and the environment where it breeds and develops. Since the establishment of Minnan Cultural and Ecological Protection Experimental Zone in 2007, China has successively set up 21 national cultural and ecological protection experimental zones in areas with concentrated non-legacy projects, distinctive features and complete contents and forms, and strived to promote each experimental zone to become a cultural and ecological zone with rich heritage, strong atmosphere, distinctive features and benefits for the people.

Carry forward and improve the practical ability of inheritance.

On the basis of continuous improvement of the intangible cultural heritage protection system, in recent years, the former Ministry of Culture put forward three important concepts: "protection in improvement", "intangible cultural heritage entering modern life" and "seeing people, seeing things and seeing life". A series of work focusing on the protection of inheritance practice, inheritance ability and inheritance environment has been carried out, which has brought intangible cultural heritage back to life and revived its vitality in contemporary production and life.

The work of intangible cultural heritage records is a basic work of intangible cultural heritage protection. Since the 18th National Congress of the Communist Party of China, the former Ministry of Culture has carried out non-legacy rescue records on the basis of previous investigation records, and gradually summed up experience and expanded and established the non-legacy record project. By the end of 2017, the central government had supported the rescue recording of 839 national representative inheritors, and the unique skills and cultural memories carried by a group of representative inheritors were recorded and preserved.

Traditional arts, traditional skills and traditional medicine and drug processing are intangible items, which are originally produced in production practice, and their cultural connotation and technical value are reflected by the production process, and the general public share their charm by owning and consuming materialized products or works of traditional skills. In view of this type of intangible cultural heritage projects, China puts forward the concept of "productive protection" to encourage and support the inheritors to actively resume production and truly realize live transmission.

In order to further promote the inheritance and revitalization of traditional crafts and expand the contingent of non-genetic inheritors, in 2015, the former Ministry of Culture and the Ministry of Education launched the training program for non-genetic inheritors in China. By the end of 2017, a total of 48,000 people had established self-confidence, been inspired and enhanced their abilities through research and training; The excellent works and rich products created and produced by the students fully show the great energy that can be generated after the creativity and imagination of the vast number of people are released.

In order to explore effective measures to revitalize traditional crafts, since March 2016, the former Ministry of Culture has supported relevant enterprises, universities and institutions to set up 10 traditional craft workstations in traditional craft gathering places, involving embroidery, wood carving, lacquer art, metal forging, traditional residential building skills and other categories. Up to now, Hami Station in Xinjiang, Xiangxi Station in Hunan, Leishan Station in Guizhou, Guoluo Station in Qinghai and Huangshan Station in Anhui have developed more than 1,000 kinds of practical products that have entered modern life, effectively promoting the creative transformation and innovative development of traditional crafts.

Accurate poverty alleviation, from "fingertip skill" to "fingertip economy"

Through productive protection, on the one hand, traditional crafts are carried forward, on the other hand, the income of the masses is increased and the poor people are helped out of poverty. Some inheritors said that "fingertip skill" has really been transformed into "fingertip economy".

In 2017, the former Ministry of Culture focused on supporting non-hereditary people in ethnic areas, remote areas and poverty-stricken areas to participate in the research and training program. Through training, the trainees not only improved their ability to inherit and practice, but also played a leading role in radiation. Take Qiandongnan Miao and Dong Autonomous Prefecture of Guizhou Province as an example. According to incomplete statistics, in the first half of 2017, only 225 students in this state participated in the research and training program, with the mode of "inheritor+cooperative/company+farmer", achieving an annual sales income of more than 750 million yuan. Excellent students returned to the local area to train new students and drive about 9,500 people to obtain employment, of which the poor accounted for 58% of the total employment, and each enterprise drove 47% on average.

Traditional process workstations have also played an important role in promoting precision poverty alleviation. In Hami, Xinjiang, 231 cooperatives and embroidery associations have been established, and more than 17,000 orders have been received. Nearly 1,000 embroidered mothers directly participated in the production of orders, with an average monthly income of 1,500 yuan per person. Hunan Xiangxi Workstation launched the "Let Mom Go Home" program to attract migrant women to return to their families by increasing the income of embroidered mothers. The workstation also negotiated 2,800 sets (pieces) of Miao embroidery orders with companies in Jinan, Shenzhen and other places, amounting to 500,000 yuan, which led to more than 160 rural women’s employment at home.

Spread communication and let excellent traditional culture shine on the world stage.

This year’s government work report proposes to carry forward Chinese excellent traditional culture and deepen cultural exchanges between China and foreign countries. As an important part of Chinese excellent traditional culture and a "living" heritage, intangible cultural heritage plays an important role in strengthening national cohesion and centripetal force and promoting exchanges and mutual learning between Chinese and foreign civilizations.

According to statistics, in the past five years, 320,000 exhibitions of intangible cultural heritage have been held nationwide, with 540 million people participating. A variety of intangible cultural heritage publicity and exhibition activities have comprehensively demonstrated the outstanding practical achievements of intangible cultural heritage protection in recent years, creating an atmosphere for the whole society to inherit and develop excellent traditional culture.

The renovation of old residential areas is a major livelihood project and development project. General Secretary of the Supreme Leader pointed out that the renovation of old residential areas is an important task to enhance people’s sense of gain, and it is also an important part of the implementation of urban renewal. The Community Construction Department of the Urban Construction Department of the Ministry of Housing and Urban-Rural Development (hereinafter referred to as the "Community Department") takes the transformation of old residential areas as the focus of doing practical things for the masses, and solves the "great livelihood" with "small incision" to continuously enhance the people’s sense of acquisition, happiness and security.

This year, this young team won the National Worker Pioneer. "The renovation of old residential areas is an important task to improve people’s quality of life, and it is a practical matter of people’s livelihood around the people. We are honored to be able to shoulder the heavy responsibility and win the honor, and we feel even more responsible. " Relevant comrades in the community office said.

Find out the base, pilot first, and clarify the direction of the transformation path

Most of the old residential areas were built before 2000. The construction standards of these residential areas are low, coupled with long-term neglect, incomplete municipal supporting facilities, aging houses and other outstanding problems. There are shortcomings in facilities, environmental supporting facilities and public services, which is far from the growing needs of the people for a better life. Residents have a strong willingness to transform. Old residential areas are large in quantity and wide in scope, and the task of renovation is heavy. How to promote renovation in a solid and orderly manner throughout the country?

Understanding what the masses think and expect, and learning from the grassroots is the first priority. The Community Department organized 20 departments and units to conduct in-depth research on 213 old communities in 93 cities and counties, and combed and analyzed the current situation, transformation needs and experience of old communities. Subsequently, Shandong and Zhejiang provinces and eight cities including Shanghai and Suzhou were organized to deepen the pilot projects, and special classes for joint work were set up with local comrades to jointly explore the establishment of nine mechanisms, such as mobilizing the masses to jointly build, sharing reconstruction funds and integrating and utilizing existing resources, and to "explore the road" in the reconstruction projects in detail, so as to accumulate experience for comprehensively promoting the transformation.

On the basis of comprehensive investigation and summing up the pilot experience, the Community Department took the lead in drafting the Guiding Opinions on Comprehensively Promoting the Renovation of Old Urban Residential Areas, which defined the target tasks and the scope of objects, established a package of support policies to meet the needs of renovation projects in terms of approval of renovation projects, taxation and finance, land and so on, basically formed the institutional framework for the renovation of old urban residential areas, and the renovation work was rapidly and comprehensively promoted throughout the country.

Guide the whole process and do a good job in deployment and implementation.

Since 2019, the country has started to renovate nearly 220,000 old urban communities, benefiting hundreds of millions of people. However, the larger new start-up tasks every year, coupled with the projects under construction, have brought great pressure to the streets and communities at the grassroots level. How to make the policy better adapt to the needs of the grassroots and land solidly?

The community department insists on keeping its eyes down, stepping down, throwing itself down and sinking into the front line, so that the policy can be passed on layer by layer from formulation to promotion to landing.

"The transformation of old residential areas is the initial intention and mission of this office. We are both policy makers and policy practitioners and implementers." Relevant comrades said.

According to reports, since 2019, the renovation of old residential areas has been included in the affordable housing project, and the General Office of the State Council has issued guidance. The Ministry of Housing and Urban-Rural Development, together with relevant departments, put forward targeted work requirements for the renovation work in that year according to the latest situation, tasks and objectives, and new situations and problems arising in the renovation, and made clear the "positive list" and "negative list" of work, so as to promote all localities to do their best and do their best to promote the renovation well and quickly.

With the gradual advancement of the renovation of old residential areas, the Community Department promptly answered questions about the difficulties encountered in various localities, followed up and summarized the deepening innovations in the implementation of policies in various localities, organized and printed seven batches of List of Replicable Policy Mechanisms for the Renovation of Old Urban Residential Areas, promoted the replicable experiences and practices in pioneering areas, guided all localities to learn from them, accelerated the improvement of working mechanisms and policy systems that meet the needs of renovation, and promoted the implementation of renovation policies.

For example, in order to solve the problem of "public needs and women need to face" in the transformation of old residential areas, the community department guides all localities to fully mobilize the masses to participate, ask for the needs of the people, ask for the people, ask for the benefits of the people, and seek the greatest common denominator of the transformation effect.

In the residents’ meeting hall of an old residential area in Qingdao, Shandong Province, a young cadre from the community office discussed the renovation plan of the residential area with the residents. Because there are many people in the surrounding primary schools during school hours, the residents are very concerned about the design plan of optimizing the internal traffic routes and getting through the fire exits. "Making policies and implementing them are different. Every old residential area has its own characteristics, and the needs of each resident are different. The renovation plan must be determined according to the wishes of residents and the actual situation of the residential area. In this process, it is very important to be with residents, want to be together, and be together. " The young cadre said with emotion.

Experience comes from grassroots practice and wisdom. The community department adheres to the typical demonstration and leads the way, and promotes the transformation process in various places with demonstration projects. Since 2021, the Community Department has identified a number of contact points communities every year, and adopted the methods of leaders’ efforts, young cadres’ on-the-spot investigation, and experts’ assistance to help the communities break the blocking points of renovation, create demonstration model projects, and share experiences and experiences with community cadres in the streets where various renovation communities are located throughout the country.

In order to evaluate the transformation work more scientifically and objectively, the community office has defined the measurement standard of the transformation work through performance evaluation, supervision and encouragement, so as to make the policy baton and the evaluation index system more unified. During the research and establishment of the National Statistical Investigation System for the Renovation of Old Urban Residential Areas, the Community Department, together with grassroots comrades, repeatedly studied the connotation of each statistical indicator in order to be accurate and efficient, focusing on the goal of timely and accurately reflecting the progress of the renovation and minimizing the statistical burden. "This set of statistical indicators has clear logic and strong pertinence, which is very helpful for guiding and promoting local work. The progress of the work can be clearly reflected in the statistics. Behind the figures are the transformation results that every resident can see and touch, and they are all tangible results. " A grassroots cadre responsible for the renovation of old communities said.

The central and local governments have resonated at the same frequency and exerted their strength in the same direction, overcoming difficulties and taking advantage of the situation. The policy implementation has not only not weakened, but the signal has become stronger and stronger.

Cooperate to fill the shortcomings and improve the supporting facilities

Living and working in peace and contentment is the simplest wish of China people. Residents spend most of their daily life, food, clothing, housing and transportation in the community. In order to do the "last mile" of serving the masses well, the Community Department cooperated with various departments Qi Xin to integrate resources and fill the shortcomings of facilities and services.

"what is missing, what to make up." The Community Office guides all localities to explore the working method of "physical examination before renovation", and before renovation, it conducts a thorough investigation of the facilities in the community, focuses on residents’ needs, adheres to goal orientation and problem orientation, adopts "menu-based" renovation, and makes precise efforts with "one district, one policy", giving priority to solving the urgent problems of the masses, using limited funds at the cutting edge and changing them into residents’ "hearts".

"Stick to the bottom line of safety" and focus on eliminating potential safety hazards. Accelerate the renovation of aging and hidden dangers of gas, water supply, heating, drainage, power supply, communications and other pipelines and pipelines, and put the concept of safe development throughout all links and the whole process of renovation.

"One old and one young" is the main concern of most families. The Community Department guides all localities to actively revitalize the housing and land resources in the community and surrounding areas, and add service facilities such as home care service centers, canteens for the elderly and children’s post stations according to local conditions. In conjunction with the State Sports General Administration, the "national ball into the community" campaign was launched, and small sports and fitness facilities such as table tennis tables were added for old communities to allow residents to move at their doorsteps.

In recent years, residents have a high voice for installing elevators in existing houses, and the community department has faced up to the difficulties of reaching a consensus and raising funds, and adhered to the combination of rule of law and rule of virtue to help solve the problem of "it is difficult for suspended elderly people to go downstairs". Seize the favorable opportunity when the National People’s Congress promulgated the law on barrier-free environment construction, and promote national legislation to support the installation of elevators in existing multi-storey houses in old urban communities. Give play to the role of grassroots organizations in street communities, take party building as the guide and residents’ consultation as the basic working methods, and promote residents to reach a consensus. In conjunction with the Supreme People’s Court, a typical case was issued to guide residents to correctly understand the legal provisions applicable to installing elevators, and to carry forward the traditional virtues of the Chinese nation, such as being good neighbors and helping each other.

Great cause inspires people to forge ahead. The achievements made by the Community Office courageously come from the broad masses of the people’s support for the major decision-making arrangements of the CPC Central Committee and the State Council, and also reflect the hope of millions of grassroots community workers and community residents to work together to build a beautiful home.

　　[XCAR Five Questions and Five Answers Original]

　　On August 22, 2016, the new E-class long-axis version of Beijing Benz was officially launched, and a total of six models were launched, with a price range of 436,800-499,800 yuan. The Mercedes-Benz E-Class long-axis version listed this time is the tenth generation model and the third generation model made in China. The new Mercedes-Benz E-class long-axis version continues the essence of S-class in appearance and interior. Compared with the standard-axis version, the wheelbase has increased by 140mm, and the configuration has been improved in all directions. The competitiveness is no longer the same as that of the old model. What are the highlights of the new Mercedes-Benz E-Class Long Axis Edition? Can face value and configuration conquer consumers? Is the comprehensive competitiveness strong? The following is to answer these questions through the special column "Five Questions and Five Answers" of Aika Automobile. Let’s talk about the editor’s personal thoughts in advance. When I see the brand-new Mercedes-Benz E-Class long-axis version, I want to buy one especially even if I borrow money. I wonder if you will have this idea after reading the following introduction!

　　Question 1: Which generation is the new Mercedes-Benz E-Class long-axis version?

　　In fact, friends who are interested in Mercedes-Benz E-Class must have a better understanding of its history, but I believe there are still many netizens who are not very clear about it, or only know about several generations of models that are closer to us. In fact, the development of Mercedes-Benz E-Class has experienced ten generations of models. For a model with a history of nearly 70 years, we have no reason not to understand its past. In other words, the first generation of Mercedes-Benz E-Class has been very far away from me. At that time, my parents were not born yet, so I couldn’t learn about the past of Mercedes-Benz E-Class from my parents, so I could only collect materials from all directions. If there is any poor introduction, please forgive me.

　　The first generation models are for you who like nostalgia.

　　Need to remind everyone that before the launch of the mid-term redesign of the sixth-generation Mercedes-Benz E-Class, it was not named after the familiar "E-Class", but named after the chassis number of W plus number.

　　　 Let’s first look at what the first generation of Mercedes-Benz E-Class looks like. The birth of the first generation of Mercedes-Benz E-Class dates back to 1947. After World War II, Mercedes-Benz resumed production of 170V and 170S models with chassis codes W136 and W191. The first generation of Mercedes-Benz E-Class was improved according to the model before World War II. The features such as independent headlights and independent rims are very obvious and full of retro style.

　　The second generation Mercedes-Benz E, the first sedan captain, is like this.

　　In 1953, the second generation Mercedes-Benz E-Class was born. The model was named 180 and the chassis number was W120. The second-generation Mercedes-Benz E-Class has completely escaped from the shadow of the first-generation model, and it is also the first sedan of Mercedes-Benz E. It adopts a non-loaded body to ensure spacious interior space. In terms of power, it adopts a 1.8L four-cylinder engine with a maximum power of 52Ps, and the transmission is matched with a 4-speed manual transmission. In 1955, the second generation Mercedes-Benz E introduced an upgraded model 190 with chassis code W121, which was not discontinued until 1961.

　　The sales volume of the fin-shaped tail of the third-generation model exceeded 620,000.

　　In 1961, Mercedes-Benz introduced the third generation E-Class with chassis code W110, including two models: 190c/190Dc. The biggest change of this generation is the fin-shaped rear design. The body size has also been upgraded, with a length of 4730mm and a wheelbase of 2700mm.

　　　 In terms of power, the 190c is still equipped with a 1.9L gasoline engine with a maximum power of 80Ps, while the 190Dc is equipped with a brand-new 2.0L diesel engine with a maximum power of 55Ps. Since 1962, W110 series has added a four-speed semi-automatic gearbox on the basis of a four-speed manual gearbox. In addition, in the later period of W110 series, a 230 model equipped with a six-cylinder 2.3L gasoline engine was added for the first time, with a maximum power of 105Ps. By the end of production in 1968, the third-generation Mercedes-Benz E-Class sold a total of 620,000 vehicles.

　　The fourth-generation models have sold more than one million years ago.

　　In January 1968, Mercedes-Benz officially launched the brand-new Stroke Eight "/8" car series, which is the fourth generation Mercedes-Benz E, with the chassis code W114/W115. This generation of cars has changed greatly in appearance, giving up the fin-shaped rear design of the third generation models and using a lot of concise and lively design styles. In addition, this generation of Mercedes-Benz E-Class models began to enrich, providing a total of 15 models for consumers to choose from, which is also a huge vehicle layout today.

　　In addition, it should be noted that the parking brake of the fourth-generation Mercedes-Benz E bid farewell to manual operation, but adopted the pedal-operated auxiliary brake that we are very familiar with, and at the same time adopted the diagonal swing shaft on the rear suspension, which improved the overall balance, comfort and stability of the vehicle. In terms of power, the W114 series is equipped with a six-cylinder engine, and the upgraded W115 is equipped with a five-cylinder or four-cylinder engine. The top 250CE model also joined the Bosch D-Jetronic electronic fuel injection system for the first time. The fourth-generation Mercedes-Benz E-Class didn’t stop production until 1976, and the cumulative sales volume was close to 2 million.

　　The fifth-generation car was made in China for a short time but left an eternal memory.

　　In 1976, Mercedes-Benz officially launched the fifth-generation Mercedes-Benz E-Class with chassis code W123. This generation of cars has undergone minor changes in appearance, such as changing the lights to horizontal design, and the shape of the water tank grille at the lower part of the front face is also very modern. This generation of Mercedes-Benz E launched the five-door travel version, two-door Coupe version and four-door long-axis version for the first time.

　　In terms of safety, the fifth-generation car has also made a qualitative leap. First, the fuel tank is placed on the rear axle of the car to reduce the danger caused by collision. In addition, a new safety steering column is added, which can fall off sideways in a side collision to prevent the steering wheel from folding into the car in an accident and causing harm to the people inside the car. In the mid-term change, this generation of E-class supports the optional ABS and driver airbag, and the safety is further improved. In terms of power, this generation of Mercedes-Benz E-Class adopts a new 2.8L inline 6-cylinder DOHC fuel injection engine on the 280E model, with a maximum power of 142Ps.

　　It should be noted that in 1988, the fifth-generation E-Class was also introduced from Changchun FAW in the form of CKD, with a total volume of 828. Less than 1,000 of these vehicles are mainly used by senior national leading cadres and foreign guests, and the number of them entering private homes is very small, which cannot be compared with today’s domestic E-class.

　　The sixth-generation car was officially named "E-Class Car" and was first imported into China.

　　In 1985, Mercedes-Benz introduced the sixth generation of Mercedes-Benz E-Class, and the chassis code was W124. In June 1993, the name of "E-Class sedan" in E+ digital mode was formally determined. This generation of E-Class sedan was also the first E-Class imported from China by Mercedes-Benz.

　　The sixth-generation E-class has changed greatly in appearance, and the overall design is more elegant and stable, and the convertible version has been launched for the first time. The weight of this generation of cars has been optimized, the handling performance is better, and the aerodynamic design is equally excellent. The drag coefficient of 0.28 is the best evidence. In terms of safety, the driver’s airbag and ABS have been changed from the option of the previous generation to the standard, and new options such as the co-pilot airbag and ASR traction control system have been added.

　　In terms of power and chassis, in addition to retaining the four-cylinder, five-cylinder and six-cylinder engines, this generation of models has also introduced a 500 E model equipped with a 5.0L V8 engine, with an acceleration time of 6.1 seconds from 0 to 100 km/h and a maximum speed of 250km/h, making it the first model equipped with the first generation of 4MATIC four-wheel drive system. In terms of chassis, this generation of models adopts front multi-link and rear independent suspension, which is more excellent in comfort and handling. In addition, in 1986, the two-door Coupe was also equipped with a 5.6L V8 engine with a completely independent cylinder head developed by AMG, which was only an engine manufacturer at that time. The maximum power reached 360Ps and the 0-100km/h acceleration time was 5.4 seconds. Then in 1990, Mercedes-Benz officially cooperated with AMG, and the launch of E 60 AMG and E 36 AMG created the history of E-class AMG models.

　　On the occasion of the May 1 ST International Labor Day in 2019, the Central Propaganda Department and the All-China Federation of Trade Unions publicly released the advanced deeds of "the most beautiful workers" in 2019 to the whole society. The picture shows the overall design team of the deep space exploration spacecraft system of the General Department of China Academy of Space Technology of China Aerospace Science and Technology Corporation at the release ceremony on April 21st. Xinhua news agency

　　The report of the 19th National Congress of the Communist Party of China expounded the initial intention and mission of the Communist Party of China (CPC) people to "seek happiness for the people of China and rejuvenation for the Chinese nation". For the happiness of China people and the rejuvenation of the Chinese nation, the purpose of China Academy of Space Technology (hereinafter referred to as "Academy") is to develop China’s space industry, serve the national strategic needs, build a world-class aerospace enterprise, and support the construction of a space power. While the whole Party is carrying out in-depth education on the theme of "Do not forget your initiative mind, Keep in mind the mission", it is of great significance to grasp, follow and apply the development law of China’s space industry, stick to its original intention and shoulder the mission bravely, so as to accelerate the development of China’s space industry and better shoulder the historical responsibility of building a space power.

　　1. Grasp the development law of China’s space industry and adhere to the development path of space industry with China characteristics.

　　Looking back on the development of China’s space industry, the development law of China’s space industry is a magic weapon for China’s space industry to create new glories from scratch and from small to large, and it is also an important cornerstone for carrying forward the past and forging ahead courageously, which must be adhered to for a long time and never wavered.

　　Adhering to the leadership of the Party is the fundamental guarantee for the rapid development of China’s space industry.

　　The most essential feature of Socialism with Chinese characteristics is the Communist Party of China (CPC)’s leadership, and the greatest advantage of Socialism with Chinese characteristics system is the Communist Party of China (CPC)’s leadership. Space cause is a great cause that concerns national security, shows national strength and embodies national will. As the main force to promote the development of China’s space industry, the establishment of the research institute is an important decision and strategic choice made by the CPC Central Committee to achieve breakthroughs in economic, national defense and scientific and technological construction in the poor and weak domestic environment. The CPC Central Committee has always attached great importance to the development of the space industry. From the beginning of the establishment of the space industry in 1956 to the present, every step forward and every leap in the development of China’s space industry cannot be separated from the wise decision-making and correct leadership of the CPC Central Committee.

　　At a time when new China is in full swing, the CPC Central Committee has made a decision to develop the space industry considering the country’s long-term development strategy. In 1958, Comrade Mao Zedong put forward that "we should also build artificial satellites", which started the journey of exploring space in China. At the beginning of the reform and opening-up, the CPC Central Committee approved the "863" high-tech research and development plan and made a major decision to develop the "New Samsung One Arrow". In the 1990s, manned spaceflight was carried out. In the 21st century, manned spaceflight and lunar exploration projects, Beidou satellite navigation system and high-resolution Earth observation system have been included in the national medium-and long-term scientific and technological development plan. Since the 18th National Congress of the Communist Party of China, the CPC Central Committee with the Supreme Leader as the core has attached great importance to the construction of a space power, demanding that we "make new contributions to the construction of a space power", which has opened a new chapter in China’s space industry.

　　History shows that the development history of China’s space industry is a struggle history of adhering to the leadership of the Party, firmly following the direction of the CPC Central Committee, and pushing the cause from victory to victory. Adhering to the party’s leadership is a unique advantage for the development of space industry, and it is also the fundamental guarantee for our brilliant achievements.

　　● Always adhering to the country-oriented value orientation is a solid cornerstone for the rapid development of China’s space industry.

　　General Secretary of the Supreme Leader pointed out that in the long history of the Chinese nation’s development for thousands of years, patriotism has always been the passionate theme and a powerful force to inspire people of all ethnic groups in China to strive for self-improvement. "Putting the country first" is a vivid manifestation of patriotism in China’s space cause. For the people in the institute, "putting the country first" means "serving the motherland with success and creating brilliance with Excellence", always insisting on putting national interests first and personal interests subordinate to national interests.

　　Looking back at the history, the development course of the Institute for more than 50 years is an epic of glorious struggle by generations of researchers, Do not forget your initiative mind, who strives for progress, values the country and dares to surpass it. In the initial stage of their career, the older generation of researchers, represented by Qian Xuesen, Yang Jiayuan, Wang Xiji and Sun Jiadong, returned to China with infinite love for the motherland, devoted themselves to the development of space, and turned China’s first artificial earth satellite — — Dongfanghong-1 was sent into space. During the period of social transformation, the people in the institute have been adhering to the belief of "I will do it if the motherland needs it", and have worked hard on their majors, laying a solid foundation for the rapid development of the space industry in the future. During the period of career development, the researchers unified patriotism, ambition to strengthen the country and the trip to serve the country, and explained the life creed of "serving the motherland with success and creating brilliance with Excellence" with practical actions.

　　History has proved that "putting the country first" is the unswerving choice of researchers. People in the institute consciously link personal ideals with the destiny of the motherland, personal choices with the needs of the country, and personal interests with the interests of the people. Adhering to the country-oriented value orientation is a solid cornerstone for the rapid development of China’s space industry.

　　● Adhering to the road of self-reliance and independent innovation is the only way for the rapid development of China’s space industry.

　　General Secretary of the Supreme Leader has repeatedly stressed that China must "adhere to the road of independent innovation with China characteristics" and "be determined to innovate independently, strengthen innovation confidence, and strive to enhance independent innovation capability." Key core technologies can’t be bought, bought or discussed. China’s space industry must take the road of self-reliance and independent innovation to build the country’s heavy weapon.

　　The development history of China’s space industry is a struggle history of self-reliance and independent innovation. During the development of the "Dongfanghong-1" satellite, the researchers were self-reliant, overcame numerous technical difficulties and created a solid "China thickness"; In the process of carrying out the manned spaceflight project, the researchers broke through and mastered the core technologies such as round-trip between heaven and earth, extravehicular space, rendezvous and docking, and on-orbit propellant replenishment, and constantly refreshed the "China speed" in the history of aerospace; During the construction of Beidou navigation satellite system, the researchers realized that the core technologies of on-board equipment such as atomic clock were in hand and 100% controllable, creating a perfect "China accuracy"; In the process of implementing the lunar exploration project, the researchers built the world’s first earth-moon relay communication satellite, realized the first soft landing on the back of the moon, and constantly refreshed the "China height" of deep space exploration; In the process of promoting the special project of high-resolution Earth observation system, researchers have broken through a series of major technical bottlenecks of high-resolution Earth observation, and supported the national people’s livelihood security with a steady "China span".

　　The road of independent innovation and development has been explored by generations of researchers in the long and arduous struggle. Adhering to the development path of self-reliance and independent innovation contains the deepest national endowment of the Chinese nation, which is the only way to climb the peak of world science and technology and the only way for the rapid development of China’s space industry.

　　● Always adhering to the scientific method of system engineering is the magic weapon for the rapid development of China’s space industry.

　　Spacecraft development is an extremely complex system engineering, which has the characteristics of great technical difficulty, high quality risk, many factors involved and complicated organization and management. Eliminating all difficulties to ensure success is the last word, and ensuring success has always been the eternal pursuit of researchers.

　　Over the past 50 years, the Institute has gradually established a scientific and perfect spacecraft development system based on system engineering theory. In the initial stage of the space industry, the Institute insisted on pre-research generation, development generation and production generation, and initially established the China spacecraft development management system. From the late 1970s to the mid-1980s, model development changed from project research to engineering development management. The Institute established a designer system and an administrative command system, and initially standardized the satellite development procedures. Since the middle and late 1980s, space technology has been fully applied to engineering, and the theory and practice of systems engineering have also entered a stage of all-round development. The Institute has carried out research and development contract management with technical and economic integration, and formed a series of systems engineering management ideas and methods.

　　Since the beginning of the new century, China’s space industry has entered a stage of rapid development, and the development of space technology has entered a critical period to achieve a major breakthrough. The number of annual launches and the number of aerospace models under research have hit record highs, which has brought great challenges to model research and production and quality management. The Institute systematically carried out the construction of three capacity projects, namely, "innovation leading", "aerospace intelligence building" and "quality improvement", and formed a scientific research and industrialization management mode of aerospace business in line with the concept of system engineering, as well as many effective scientific research and production management mechanisms and quality management rules and regulations, which laid a solid foundation for the smooth development of model development, continued to promote the transformation and upgrading of spacecraft development mode, and created a new chapter in the transformation and upgrading of China’s space research and production mode.

　　For decades, generations of researchers have always adhered to the scientific method of systems engineering, ensured the complete success of the model launch mission with scientific management methods and a high degree of vigilance, and promoted the steady development of the space industry. Adhering to the scientific method of systems engineering is the magic weapon for the rapid development of China’s space industry.

　　● It is an inexhaustible source for the rapid development of China’s space industry to always adhere to the strategy of strengthening the enterprise through talents and continuously inherit and carry forward the space spirit.

　　Behind every brilliant aerospace achievement, there are a large number of aerospace talents who love the motherland, selfless dedication and innovation.

　　The aerospace spirit is an important part of the Chinese national spirit and a powerful spiritual driving force for the leap-forward development of the aerospace industry. In the process of composing China’s space career for more than 50 years, the Institute has become an important birthplace of the traditional spirit of space, the spirit of "two bombs and one satellite" and the spirit of manned space flight. During the vigorous development of the space industry, the connotation of the space spirit pedigree has been continuously enriched, and the spirit of Beidou and the spirit of exploring the moon have been condensed and formed. They are the continuous enrichment, perfection and sublimation of the space spirit, which has injected more abundant model characteristics and era connotation into the space spirit pedigree.

　　The aerospace spirit has inspired generations of researchers to move from victory to victory. They have been deeply integrated into the blood and soul of the people in the institute, and they are a powerful spiritual driving force for the institute to make concerted efforts to promote the development of the space industry. It is with such a top talent team and brilliant aerospace spirit that the researchers can further overcome difficulties, persevere, keep their motivation and continue their struggle. We firmly believe that it is an inexhaustible source for the rapid development of China’s space industry to always adhere to the strategy of strengthening enterprises through talents and to always inherit and carry forward the space spirit.
