After the founding of the People's Republic of China, the education and scientific research of the tea industry received the attention of the party and the state, which further stimulated his work enthusiasm. 1952 national colleges and universities adjust departments. He volunteered to work in Anhui, where working and living conditions are difficult and tea is abundant, and served as an associate professor and head of the tea industry department of Anhui Agricultural College. He personally grasped the formulation of teaching syllabus, curriculum setting and the construction of production practice base, and did a lot of hard and meticulous work for the establishment of the department and the gradual normalization of teaching and scientific research. 1957 promoted to professor. During this period, he also devoted himself to improving the teaching level of tea making, edited the teaching materials of tea making and tea inspection in national agricultural colleges twice, and published monographs such as Tea Cultivation Technology, Anhui Tea Classic and Fried Green Tea. Even after he was forced to leave his teaching and research posts during the Cultural Revolution, he never stopped writing. Combining his own teaching and practical experience, he sorted out the data collected at ordinary times and wrote the Complete Book of Tea Making, which is divided into five volumes, including general introduction, green tea, yellow tea and black tea, white tea and green tea (commonly known as oolong tea) and black tea, 1 more than ten thousand words.

After the Cultural Revolution, he returned to the front line of teaching and scientific research. At this time, although he is old and weak, his spirit is even more radiant. He said: "I am like an' old tea tree' in the severe winter. Spring has come, and my' old tea tree' has sprouted again. " 1977, although his myositis recurred and he could not walk, he still endured the pain. On his deathbed, he wrote three representative works of * * * 1 10,000 words day and night, expressing an intellectual's contribution to the party. At the same time, he also put forward the idea of developing tea education to the State Council. 1978 suggested and participated in the establishment of the first mechanical tea specialty in Anhui Agricultural College. 1 September, 978, regardless of his old age and infirmity, he led tea teachers from nine universities to go deep into tea areas in Yunnan, Guizhou, Sichuan and other places, which lasted for1several months, collected scientific research materials on tea production, enriched the contents of tea making, and completed the task of editing the textbook "Tea Making" in agricultural colleges and universities assigned by the Ministry of Education and the Ministry of Agriculture on time. Later, the Theory of Tea-making Technology was edited as a compulsory course for graduate students, and Selected Famous Tea in China was edited as a supplementary teaching material for tea-making science. As his students said, "Teacher Chen's life is a life of writing books and educating people." After completing the above-mentioned textbooks, he set out to compile the teaching materials for tea economy specialty, edited Tea Commodities, and was entrusted by the Township Enterprise Administration of the Ministry of Agriculture to compile Tea Management, as well as Tea Pharmacy, Tea Marketing and Tea Trade. Some of these textbooks have been published or will be published soon. He said: "I don't have much time left. I want to finish the last textbook of tea economics, so as to initially establish a complete tea education system in China and the main textbooks of various majors." That's how he persisted in his pursuit and worked sleepless nights. He said: "What impressed me most was Chairman Mao's two words: We should have what foreigners have, and we should have what foreigners don't have. I will fight for this for a lifetime and establish a tea education system that foreigners do not have. "

For decades, Chen Xun has never stopped studying tea science while teaching. As early as 1940s, he made pioneering research in tea-making technology and tea chemistry, especially in the theoretical research of tea "fermentation", and made remarkable achievements, put forward the theory of tea-making discoloration, and demonstrated the principle, mechanism and essence of tea-making discoloration. It is proved that the change of tea-making technology is mainly the oxidation change of tea polyphenols under certain conditions, thus forming the quality and color of various teas. 195 1 year, Academician Oberlin, President of the former Soviet Academy of Sciences, came to China to attend the May 1 International Labor Day. He specially went to the tea professional class of Fudan University and asked Xie Chen about the method of making yellow tea. Xie Chen wrote most of the contents of Tea Chemistry Research in an outline on the blackboard. After reading it, the President found that his hypothesis that "tea fermentation is related to respiration" was to publish an article in a magazine after returning to China, and highly praised Chen Xun's contribution to tea science research. The article wrote: "Who said that China people don't study tea? Isn't Professor Chen Xun from Fudan University doing fruitful research!" After the founding of the People's Republic of China, tea research was paid attention to and the conditions were much better. Chen Xun concentrated all his energy on tea teaching and scientific research, constantly experimenting and summarizing, and writing monographs and papers day and night. By August 1990, * * published 189 (Ministry) * * 650.

Since 1980s, many foreign scholars have come here or written to Chen Xun for advice. Matsushita Sukeyoshi, president of Japan Association, made a special trip to Hefei to ask about the origin of tea making and drinking. In February, 1987, Professor Ji, a Japanese black tea expert, also made a special trip from Japan to attend the 80th birthday celebration. She said in her message: "Mr. Xie Chen is my mentor. Like a loving father, he guided me in many ways. I am an immature researcher, and my research has just begun, mainly engaged in the research of Japanese black tea. In the future, under the guidance of Mr. Xie Chen, I want to continue to conduct in-depth research from all angles ... "198710, the Royal Agricultural Center invited Chen Xun to participate in the Royal International Agricultural Exhibition. Although it is inconvenient to travel because of his age, several of his works have also had great repercussions after they were exhibited in the exhibition. In addition, he wrote two papers, The Origin of Tea Tree and Its Original Species and Twelve Views on Tea Culture, for the first International Symposium on Food Culture in China, which was co-sponsored by Beijing Municipal Government, China Food Industry Association, Cuisine Association, China International Economic and Technical Exchange Center and Beijing International Symposium on Food Culture. All these activities have promoted the tea culture and academic exchanges between China and the world. It has been 50 years since Chen Xun 1940 boarded the university forum. At present, at the age of 80, he is still giving lectures to students in the classroom in person, rain or shine, and one stop in front of the blackboard is two hours. Everyone was moved by his passionate educational enthusiasm and selfless work spirit.

He is rigorous in his studies and tireless in teaching others. For decades, he treated every class meticulously and sometimes attended important meetings. He always makes up lessons in time after the meeting. He often invites students to his home to listen to their opinions on teaching in order to improve the quality of teaching. He said: "Teaching and scientific research are the primary tasks of our university teachers. Without improving the quality of teaching, it is impossible to train talents for the four modernizations. " Tea commodities were increased from the original 8 chapters to 14 chapters, which were supplemented and rewritten on the basis of accepting students' opinions.

Chen Xun is good at reforming teaching methods and actively promoting heuristic education. He asked students to preview three times before class and read the whole chapter for the first time; Find out the problem of the whole chapter for the second time; Draw a problem in red ink for the third time, then think for yourself and solve it by yourself. If there are any difficulties, discuss them among the students first. If there is any problem that can't be solved, just ask the teacher in class. This teaching method is adopted in the national tea-making assistant training class and postgraduate class. At the end of each chapter, everyone should write a book report. This not only comprehensively reviews and summarizes the main contents of this chapter, but also exercises everyone's written language expression ability. Chapter papers submitted by classmates, short 1000 words, long 1000 words, he carefully read them. Some also communicate with students face to face, or point out shortcomings, or praise students' independent opinions. He often personally guides students' tea-making practice, sets an example, patiently and meticulously explains the principle of tea-making and personally guides the operation technology. Sometimes, in order to make good tea, they have to operate continuously until late at night, and even can't afford to eat.

While teaching, he also attaches importance to educating people and ideological education of students. He said: "In the past, the education method of teaching without distinction killed people and must be completely reformed. In order to cultivate qualified senior scientific and technological talents, teaching must teach people. " Because he is approachable, affable, enthusiastic and concerned about his classmates, many students often come to consult him. He never treats visitors and letters differently according to their status and age. His rule is, give whatever people want, whatever comes. He has been rated as an advanced worker, excellent teacher and educator for many times, and won the second prize of teaching achievement in national colleges and universities 65438-0989.

For more than half a century, Chen Xun has trained several generations of tea science and technology talents for the country. In addition to 2-year junior college students and 4-year undergraduate students, 1980 resumed the postgraduate system, and 13 enrolled graduate students majoring in tea making, tea machine, tea inspection, tea history, tea trade and tea marketing. In order to speed up the training of teachers in colleges and universities, 1986 set up a national advanced course for tea-making teaching assistants, compiled teaching materials and taught the course "Tea-making Technology Theory". And cooperate with the Ministry of Agriculture, the Ministry of Commerce and other units to hold a national tea-making technology training class, as well as training grassroots technical forces through short-term study classes in the countryside. Through the above-mentioned multi-level teaching methods, he has trained generations of senior and middle-level talents for the country, and many of his students are professors, experts and business backbones of the tea department. Xie Chen, who is at the forefront of tea education, has been paying close attention to the development of tea production in China. He often takes advantage of attending meetings and other channels to advise the State Council, the Ministry of Agriculture, the Ministry of Commerce, the Ministry of Foreign Trade and the Anhui provincial government on how to develop tea production in China and Anhui. He also used professional publications such as China Tea Newspaper, Tea Newspaper, People's Daily and Anhui Province edited by him. For example, 1958 published the achievements and future development direction of China tea industry after liberation, 1965 published the development of tea production in China, 1979, 1980 published the management system must be completely reformed. 1983 the disconnection between production and sales of tea commodities must be studied and solved; 1984, international tea market trends and China tea promotion countermeasures; World tea market forecast; 1987, the production of famous tea and the development of tea industry; In rural areas, science and technology is the only way to help the poor and get rich in mountainous areas.

He has always stressed that tea scientific research must be combined with production practice. 1972 personally went to Fuzhou tea factory to participate in the national collaborative national project "Study on the new technology of isolated scenting jasmine tea", and wrote papers such as "Experimental study on the innovation of jasmine tea production technology" and "Physical and chemical properties of jasmine tea". 1988 led graduate students to Anhui juntianhu tea factory to study the characteristics and optimum design combination of tea kneading machine ribs. Since 198 1, under his auspices, he has organized 64 experts and scientific and technological workers from tea education, scientific research and production units all over the country. After four years of investigation, data collection, sample preparation, composition determination and sensory evaluation, the Selected Extracts of Famous Tea in China was compiled on 1985.

Since the reform and opening up, he has spent about13 of his time in the tea country every year, sending science and technology to the countryside, guiding tea production, improving tea-making technology and taking the lead in creating famous tea. During the period of 1984 ~ 1986, he braved the hot summer to give lectures for three times and helped to create famous teas such as Qinba No.5, Wuzixian and Hanshui Yinsuo, which greatly changed the face of tea production in Shaanxi, significantly improved the quality and technology of tea making. He has visited Ningguo, Qianshan, Taihu Lake, Jinzhai, Huoshan, Xuancheng, Wuhu, Guichi, Dongzhi, Hanshan, Jingde, Lu 'an, Qingyang and Jiuhuashan in Anhui Province for many times to guide tea making, which has regenerated many lost famous teas such as Tianhua Gujian (Nanyang Gujian) and created "Tianshan Mountain is really fragrant" and "Qishan Cuimei".

Chen Xun has worked hard for the tea industry for more than 50 years, and his selfless dedication and contribution to the people have always been respected and admired by people. People's Daily, Guangming Daily, Wen Wei Po and other domestic newspapers have reported his deeds many times. However, he is still not satisfied with what he has achieved. He said, "Although I am very old, I still have a lot of work to do." He expressed his determination to devote all the waste heat to the tea industry in China.
