His skin was tanned and he had a good time talking with a group of old people in the mountain village - you might not think he was a young scholar when you first met Zhang Jie. Zhang Jie, 36, is an associate professor at the school of traditional Chinese medicine of China Pharmaceutical University (hereinafter referred to as "Yaoda"). Usually, he is either wearing a white coat and burying his head in the laboratory equipment, or standing on the podium to teach. Now, he walks on the undulating mountain road, which looks no different from the local villagers. When it comes to tanned skin, Zhang Jie smiled brightly: "here is strong ultraviolet!" in his mouth, "here" is Zhenping county, Ankang City, Shaanxi Province. This year is the tenth year that Yaoda has helped Zhenping county. In the past 10 years, Yaoda has sent three temporary first secretaries and five temporary deputy county heads to Zhenping county. In March 2020, Zhang Jie took over the temporary deputy county head. In novel coronavirus pneumonia, Zhang Jie first went to Zhenping county during the half month of isolation. Located at the junction of Shaanxi, Chongqing and Hubei, it is said that "nine mountains, half water and half fields". "There are few plain areas and the land is not contiguous, but the forest coverage is high. Traditional Chinese medicine resources are the biggest advantage here," Zhang Jie said. After the isolation period, he visited the agricultural product development enterprises in the county and soon found the problem. "The traditional Chinese medicine planted by the villagers is directly sold to drug dealers. Most enterprises are only rough processed agricultural products with low profits. I thought that we should further develop and process the medicinal materials with the same origin as medicine and food". In the past, the local villagers were conservative and dared not try new things. Zhang Jie insisted on the principle that "it is better to teach people to fish than to teach people to fish". He believed that only when the industry is revitalized can there be long-term development here. Now the famous Jinsi Huangju herbal tea is the "representative work" of Zhenping traditional Chinese medicine product processing. Zhang Jie told reporters that in the past, most of the enterprises here only made and sold golden silk chrysanthemum dried flowers. Professor Tan Ninghua, Dean of the school of traditional Chinese medicine of the University of pharmacy, led the team to conduct in-depth research and communicate with the school and the local area, took the initiative to propose the R & D project of Jinsi Huangju herbal tea, successfully developed and transferred two "Jinsi Huangju" drinks to Zhenping local enterprises for free, assisted the enterprises in listing declaration and processing and production, and conducted countless experiments only on the taste of herbal tea. In the stage of trial production and formal production, they and local enterprises keep an eye on the production line in the OEM factory and check it in person, often staying up until one or two late at night. The development of Jinsi Huangju herbal tea has helped the local extend the industrial chain, developed three Jinsi Huangju planting bases with a total of more than 1000 mu, cultivated a number of enterprises such as Jinrui Agricultural Development Technology Co., Ltd., and also promoted the increase of farmers' income. Lang Shixiang, a villager in jianshanping village, Huaping Town, is an employee of Jinrui Agricultural Development Technology Co., Ltd. she told reporters that her husband is in poor health and can hardly do any work. She is the "vanguard" of the company's golden chrysanthemum planting and picking staff. She undertakes the task of cleaning the company in the slack season. She also raises several pigs at home. Last year, her income was 700000 yuan. In May this year, after Jinsi Huangju herbal tea went on the market, the first batch of 50 tons of herbal tea has been basically sold out. Hu Juan, chairman of the company, revealed that this product is under extended development. It is expected that the annual production capacity will reach 500 tons and the output value will reach 30 million yuan. In addition to Jinsi Huangju herbal tea, there are many "babies" in Zhenping: agaric, bacon and selenium rich Potatoes... These "babies" are not popular because they lack two ways: one is the road and the other is the market. Zhang Jie still remembers his first visit to Zhenping: "it took one day from Xi'an to Zhenping, and it took seven hours to walk on the mountain road! It was carsick and scared." at that time, he was thinking: "without transportation, there would be no investor, no industry, no industry, no economy..." In August 2020, the newly opened Pingzhen Expressway greatly shortened the time from Zhenping to the outside world. When Li qine, a local girl, was a child, she had to take a car for four or five hours to go to Ankang City. Now it only takes one and a half hours. At the opening ceremony of Pingzhen expressway, the first batch of golden silk Huangju herbal tea incubated by enterprises came on stage. Since then, other Zhenping specialties began to be sold all over the country along this road. The highway is unblocked, but a suitable market is still being explored. Zhang Jie, who has no marketing experience, asked for advice everywhere: "how to grasp the key points of publicity? How to develop Zhenping market?" in order to solve the problem of unsalable agricultural products, he tried to bring goods live, stood solemnly in front of the camera and became the representative of mushrooms and bamboo shoots; I also contacted Yaoda and held activities such as "eating Zhenping food for one yuan" and "Zhenping agricultural products into Yaoda", which were very popular at the sales site. Yang Yang, a Zhenping student studying at Pharmaceutical University, told reporters that she ate Zhenping bacon as far away as Nanjing and felt "very family flavor". Zhang Jie was once a teacher of Li qine. In the hearts of the students, he is a "knowledgeable 'master of scientific research' with funny and humorous lectures". After graduating from Pharmaceutical University, Li qine chose to return to the drug and food inspection and testing center of the market supervision bureau in his hometown to return this land with professional knowledge. In Zhenping, teachers and students meet again. What impressed Li qine most was Zhang Jie's iconic laughter. "I can meet Mr. Zhang every day at work. He is very kind and has no sense of distance.". Zhenping is always called the "second hometown" by the teachers and students of Yaoda. There seems to be a solid bridge between Zhenping and Yaoda. Zhang Jie and the teachers of Yaoda who once adhered here are like piers. With their support, a distance of 1000 kilometers can not hinder the closeness of Zhenping and Yaoda. "Everyone does scientific research in different ways. Some people write papers and others do experiments in the laboratory. I do experiments on the earth and write papers on the earth." Zhang Jie, who came to Zhenping for a year and a half, said, "in my opinion, scientific research should eventually serve the society, bring value and benefit one party." (outlook new era)
