The reform and opening up since 1978 has gone through 40 years. The Third Plenary Session of the Eleventh Central Committee of the Communist Party of China has brought about great social and economic changes in China, and also caused life changes in Chinese, especially the younger generation. After 40 years of reform and opening-up, young people entering the new era in Socialism with Chinese characteristics are the "innovative generation" and "fashionable generation".

　　Top Ten Popular Words of Youth and Their Changes

　　Looking back on the 40-year history of China’s reform and opening-up, the author sums up ten popular words among young people, mainly including — —

　　★ Dare to drink soup.

　　Reform and opening up means "invigorating the country and opening to the outside world". The younger generation took the lead in exploring and trying, and stepped out of the new step of the reform era with the courage of "daring to drink soup". "Tou Pei Tang" is a folk language in the Pearl River Delta region, which means that whoever dares to try the first soup cooked will dare to drink it first. Looking back at history, from the courage to drink soup to the rationality of "discharging pollutants without exclusion", it is an important support for the continuous development of reform and opening up, the continuous change of young people’s ideas and lifestyles.

　　★ Time is money and efficiency is life.

　　After the reform and opening up, young people gradually face market development, commodity trading and money exchange. Especially in special economic zones and coastal open cities, emphasizing money and efficiency has gradually become a popular concept. The most popular saying is that "time is money and efficiency is life". Young people not only earn money by labor and talent, but also don’t indulge in money and enjoyment. Instead, they pursue friendliness, mutual assistance, honesty and beauty beyond money, rich life value and sound personality development.

　　★ Start with me

　　In 1979, Tsinghua University students took the lead in shouting the slogan "Start with me", which spread from colleges and universities to communities and rural areas, and to plains and mountainous areas, and became the strongest voice to inspire people, especially teenagers, to work hard and study hard. "Starting from me" advocates that people take the initiative to take the responsibility of promoting social development and progress, participate in social affairs for their own happiness, and actively contribute.

　　★ going to sea

　　"Going to sea" is actually a figurative word, which means that young people jump into the "sea" of commodity economy and market competition and struggle and survive independently. In the early days of reform and opening up, it means jumping out of traditional organs, state-owned enterprises and units to make a living freely. Then the word "doing business" appeared, and self-employed, Hong Kong-funded enterprises and foreign-funded enterprises were all included in this scope. It is this large number of young people who "went into the sea" and "went into business" that gave birth to many outstanding entrepreneurs and outstanding management talents, and created the miracle of China’s economic development.

　　★ foreign cut in line

　　The popular "foreign jumping in line" among young people is a paraphrase of the saying that educated youth went to the countryside to "jump in line" in the 1960s, and transplanted to point out the generation studying in China. The author finds that it is closely related to the economic development and power enhancement of China after the reform and opening up to the outside world, which is a rare opportunity to be enjoyed by children from ordinary middle-income families. The younger generation who have gained all kinds of knowledge and insight through "studying abroad" will bring new ideas and new horizons after returning home, injecting new forces into economic revitalization and social construction.

　　★ Chuangke

　　"Maker" is a popular term among young people in recent years, which is influenced by both foreign fashion and national leaders’ emphasis on innovation and entrepreneurship. Specifically, "maker" refers to a person who turns ideas into reality without making profits. After social communication, "maker" refers to young people who have innovative ideas and start their own businesses. The survey found that the generation of "Maker Generation" benefited from China’s opening to the outside world and economic development. After helping young people get rid of poverty and solve the problem of food and clothing, in order to realize their dreams, create the value of life, constantly surpass themselves and break through the society, and obtain the development and changes of science and technology, economy, culture and welfare.

　　★ Networm

　　There are some names for the youth network generation, such as "netizen", "net bug" and "net fan". The author finds that with the growth and maturity of teenagers after 1990s and 00s, the diversity and hierarchy of online games will become increasingly obvious, and new games such as "indie games" which focus on humanity, artistry and creativity will become a new bright spot in society and a new element to guide the development of teenagers’ interests. The Internet age has triggered teenagers’ recognition of "Internet addicts", brought opportunities such as online knowledge, online games, online entrepreneurship and online employment, and pushed China into a brand-new development environment.

　　★ wonderful flowers

　　The original meaning of "exotic flowers" refers to strange and beautiful flowers, which are often used to describe unusual outstanding literary works or outstanding people. Now it is a metaphor for someone (or something) who is unconventional and full of personality. Especially, young people after 90s and 00s have rendered this word into a popular discourse of "both praise and disparagement", "both praise and disparagement", "derogatory with praise" and "seemingly derogatory with real praise", which has more social significance. The reasons why the post-90 s and post-00 s youth are keen to participate in and watch the "Qipa Theory" are, on the one hand, to hear all kinds of ideas and statements that are the same as their own hearts in the debate; On the other hand, it is to see the "strange" youth shine and shine in the debate; Have a special sense of identity and pride.

　　★ Volunteer service

　　The spirit of "dedication, friendship, mutual assistance and progress" advocated by chinese young volunteers association inherits the tradition of "learning from Lei Feng and doing good deeds", and adapts to the young generation’s desire to give back to society and help others while increasing their income and improving their lives, and provides opportunities to participate in social services. Volunteerism can become an important part of the socialist core values in China today, and the full development of the core values has laid a more solid foundation for the cause of voluntary service. Guide young people to form healthy values and good personality in the practice of caring, dedication and helping others.

　　★ World Fan

　　China has gone through a century of exploration and 40 years of reform and opening-up, from "closed door" to "open eyes to see the world" and from "bringing in" to "going out". Nowadays, young people are more and more confident, more and more proud, more and more international thinking and international vision, and dare to stand on the international stage.

　　The social value of the change of youth’s concept

　　On the surface, the changes of youth catchwords are only "changes in words and entries", but behind the emergence and evolution of each word, it has an important influence on the social times; At the same time, the emergence of every new concept and consciousness of young people has a positive role in promoting the social structure and promoting the deepening and popularization of reform and opening up.

　　(A) innovative social concepts

　　Looking back on the changes of youth catchwords in the 40 years of reform and opening up, we can find that on the one hand, with the social changes, the younger generation is constantly born with new ideas and new pursuits; On the other hand, the development of youth catchwords has become an important element of social fashion and a manifestation of social civilization and progress. It can be said that the change of young people’s ideas has promoted the continuous generation of new ideas, new concepts and new consciousness in China society, and maintained the vigorous vitality and development vitality of society.

　　(2) Innovating the social system

　　Ideas play a guiding role in practical behavior. Since the reform and opening up, the changes of youth catchwords have not only affected the development and changes of generations of young people and even generations of Chinese, but also become an important driving force for innovating social system and social structure. When people in the past were still used to relying on the "unit system" and "iron rice bowl", a large number of young people took the lead in choosing "the tide of going to the sea" and "the tide of working", and chose the work and living space outside the "old system". These industries and occupations, which were very humble and neglected at first, have gradually become an important force of China’s socialist market economy and an important part of the new social system and structure. In the process of China’s economic system and social reform in the future, the exploration and practice triggered by young people’s new ideas will further promote institutional innovation and structural changes, and will provide a strong impetus for social modernization.

　　(3) Innovating social resources

　　Since 1978, human resources, including young people, have been stimulated through reforms such as the rural "contract responsibility system" and the urban "enterprise responsibility system", which has become an important element to promote social development and progress. Since the 1990s, with the increasing opportunities for young people to choose freely, start their own businesses and form their own associations, more types of resources have emerged to promote social development. Youth social organizations, in particular, have become a new field of youth employment and entrepreneurship, and a new force to give full play to youth creativity and promote social civilization and progress. These resources are different from all kinds of resources in the original social form, and communicate a solid foundation for the development of Socialism with Chinese characteristics in the new era.

　　(D) Innovative social networks

　　In the 40 years since China’s reform and opening-up, generations of young people have experienced constant changes in social networks. The "acquaintance network" under the background of traditional villages has gradually broken through, expanding to the "stranger network" in the process of urbanization and entering the "virtual network" in the network age and information society. It can be said that the elderly are the "aborigines" of traditional community and village life, while the youth are the "aborigines" of the information network society. On the one hand, they actively regard network technology and information resources as the basis of building new social relations, and the whole country and even the whole world can establish cooperative development through "virtual relations" to create new wealth and resources of society; On the other hand, the relationship between "virtual network", "stranger network" and "acquaintance network" is actively reconstructed under the new historical conditions, so that tradition can be rejuvenated by fashion.

　　Studies have shown that long-term intake of waste oil will cause obvious harm to human body, such as developmental disorders, enteritis, hepatomegaly, heart and kidney enlargement and fatty liver. Aflatoxin, one of the main hazards in gutter oil, is a strong carcinogen, and its toxicity is 100 times that of arsenic. Another question is ethical. Can you eat the oil that others have eaten, which goes bad in the sewer and is fished out again?
　　So, is there a simple way to identify gutter oil? We might as well listen to what food science experts and insiders say.
one
There is no good way to scientifically identify waste oil at present.
　　In an era of paying attention to food safety, the ideal state is that when you go to a restaurant, you take out a test paper and dip it in the dish. After a while, you take it out and compare it with the spectrum table, and then shout, "Boss, change the oil!"
　　However, the reality is that up to now, scientists have not found an ideal means to detect and identify gutter oil.
　　"Oil mixed with oil, fairy sorrow, fairy is difficult to separate it. Waste cooking oil has a history of more than 20 years. Even today, we can still see waste cooking oil in rural markets and urban-rural junction markets, and we also feel that it has entered the dining hall. If calculated by tonnage, there should be millions of tons of waste oil digested every year. I am very embarrassed. We can’t find a very effective technical means to identify it. This oil is gutter oil, and this oil is not gutter oil. " When attending a CCTV program, Hu Xiaosong, vice president of the College of Food Science and Nutritional Engineering of China Agricultural University, once said this.
　　Hu Xiaosong pointed out that the current detection methods have not overcome this technology and cannot scientifically distinguish the quality of oil, but the Ministry of Science and Technology has set up a special project for this matter, and I believe that it will be possible to distinguish the quality of oil by scientific means in the near future.

Traditional detection methods have certain limitations.
　　In the view of scientific researchers, the difficulty in treating gutter oil lies in that it is difficult to distinguish gutter oil from ordinary oil only from appearance and sense after refining processes such as washing, distillation, decoloration and deodorization. Illegal traders will also mix waste oil into edible oil, and if the content is small, it is even more difficult to detect.
　　He Dongping, a professor at the School of Food Science and Engineering of Wuhan Institute of Technology, has been engaged in the research of gutter oil for many years. In He Dongping’s view, the traditional detection methods only grasp a certain characteristic of gutter oil, and no method can effectively detect gutter oil from different sources at the same time, which sometimes leads to a large detection error and more possibility of misjudgment.
　　Wang Le, a graduate student of Wuhan Institute of Technology, once developed a blue test paper. With the increasing proportion of waste oil, the blue test paper will show yellow-green, light yellow and bright yellow. This is based on the "accumulation" of oil to detect the purity of oil, but this method is also limited by the proportion of waste oil added.
　　On the Internet, you can find a company specializing in the production of "Quick Detection Kit for Waste Oil", but from the instructions provided by the company, "for some unpurified oils (such as sesame oil, pepper oil, etc.) and oils with other ingredients (such as Chili oil), this method is easy to produce false positives".

Identify the waste oil refrigerator?
　　Senior chef Feng Peng, who once worked as a chef and executive in many big restaurants in Beijing, said that under normal circumstances, gutter oil and ordinary oil can’t be distinguished, and it is inevitable to be fooled when purchasing. He can only judge by practice: restaurants usually need to oil before cooking. In this "lubricating oil" process, good oil can be used seven or eight times repeatedly, while waste oil will become sticky and have a spicy taste after being used for up to three times.
　　"In addition, when the outdoor temperature is low, waste oil will solidify like palm oil, so people often use waste oil to pretend to be palm oil." Feng Peng said that gutter oil can be identified in winter and can be tested in the refrigerator in summer. Some media think that gutter oil has a taste and can be smelled out. In addition, it contains a lot of water, and the pot will explode. Feng Peng thinks these are nonsense, because water can’t be mixed into oil at all, and gutter oil has no odor.

four
How should we identify waste oil?
　　Take a look. Look at the transparency, pure vegetable oil is transparent, and the transparency will decrease due to the mixing of alkali grease, wax and impurities in the production process; Look at the color, pure oil is colorless, and the oil will be colored because the pigment in the oil is dissolved in the oil in the production process; Look at the sediment, its main component is impurities.
　　Second smell. Each oil has its own unique smell. You can drop a drop or two of oil on your palm, rub your hands together, and smell it carefully when you are hot. Oil with odor indicates that there is a problem with the quality, and it is likely to be waste oil with odor; If there is a smell of mineral oil, you can’t buy it.
　　Three tastes. Take a drop of oil with chopsticks and taste it carefully. The oil with sour taste is unqualified, the oil with bitter taste has been rancid, and the oil with peculiar smell may be waste oil.
　　Listen. Take one or two drops of oil from the bottom of the oil layer, coat it on flammable paper, light it and listen to its sound. The products with normal combustion and no noise are qualified products; If the combustion is abnormal and makes a "squeaky" sound, the water content exceeds the standard and it is an unqualified product; The "crack" explosion during combustion indicates that the water content of the oil is seriously exceeding the standard, and it may be adulterated products, so it is absolutely impossible to buy.
　　Five questions. Ask the merchant about the purchase channel, ask for the purchase invoice or check the sampling test report of the local food hygiene supervision department if necessary. (Comprehensive by this newspaper)
