Cctv news(Focus Interview): Young people are just at the age with the most entrepreneurial passion and innovation enthusiasm. They have a fiery heart to pursue their dreams and Excellence, and their struggle is a vigorous force to promote scientific and technological innovation. China should strive to become a major scientific center and an innovative highland in the world, and young people should be the pioneers. Today, we will look at two scientific and technological workers. One chooses to engage in scientific research and develop new drugs in colleges and universities. Another chose to start his own business and transform scientific and technological achievements. They all dare to wade in dangerous beaches and break through difficulties, full of the spirit of struggle.

In a laboratory in Hefei, Anhui Province, 33-year-old Li Junpei is busy testing a new product with his colleagues. This macromolecular colorant is a new type of environmental protection dye with independent intellectual property rights.
Traditional dyes are all small molecules, which are easy to be absorbed and migrated, that is, people often say that they are easy to fade and easily absorbed into the human body. Macromolecule colorant makes small molecules hand in hand into chain-shaped or net-shaped macromolecules, which are directly locked in the material, so it is not only difficult to fade, but also can not be absorbed by human cells and becomes a safe colorant.

Li Junpei, Ph.D. in Polymer Chemistry, graduated from University of Science and Technology of China. Now he is the founder of a color chemistry technology innovation enterprise. In their R&D center, at least 20 similar experimental reactions are carried out at the same time every day. Through continuous experiments, they have successfully developed more than 100 kinds of macromolecular colorants with monomer colors, and more than 3,000 kinds of colors can be prepared with them.
It is with this perseverance that Li Junpei’s team broke the foreign technology monopoly. Now, they are conquering a new fluorescent colorant, hoping to apply it to medical detection, thus improving the detection speed and accuracy.
Li Junpei was born in a small mountain village in Heze, Shandong Province, and was the first doctor in the village. Since university, his research direction has been new polymer materials. During his school years, he got more than 20 national invention patents.
But it is not enough to have love. Li Junpei found that in China, compared with the lack of scientific research technology, what is lacking is the landing of scientific research results. In April 2016, the words made by the General Secretary of the Supreme Leader during his visit to the University of Science and Technology of China strengthened Li Junpei’s determination to go out of the laboratory for scientific research transformation.

Li Junpei didn’t break his word. In 2018, after completing the postdoctoral research, he did not enter universities and scientific research institutions, and refused the high-paying employment of foreign companies. Instead, he chose to start a business and specialize in the application of color chemistry materials. Although he got the first investment of 5.4 million yuan with patents and new technologies, set up a team of more than 20 people and set up a laboratory, he ran out of money before he started to do something big.
In addition to the lack of funds, Li Junpei was often shut out when promoting new materials and technologies, and was even rejected by nearly 200 units at most. This is the darkest moment for Li Junpei’s team, but they still haven’t given up. In October 2019, they finally turned around and got a support fund of 20 million yuan from the Shaoxing Municipal Government. The company’s operation is gradually on the right track, and its income has also changed from 13,000 yuan to 280,000 yuan, reaching 8 million yuan in 2020. The income in the first quarter of this year has exceeded that of last year. Now, Li Junpei’s team has more than 70 people, with an average age of 27.
At present, the macromolecular colorant developed by Li Junpei’s team has been applied in cosmetics, daily chemicals, children’s toys, food packaging and other fields. Li Junpei has made two "five-year" plans for the company, aiming at better application and popularization of macromolecular technologies and materials in China and solving the problem of high pollution and high energy consumption in the printing and dyeing industry.

Thalidomide is a famous tragic event in the history of chemistry and medicine. The person who is telling you this story is Qin Chong, 34 years old. He is one of the youngest professors and doctoral supervisors in the School of Medicine, China Ocean University, and is currently leading you to study new anti-tumor drugs.
In 2015, Qin Chong graduated from Peking University with a doctorate in medicinal chemistry. From 2016 to 2019, he studied at the University of Michigan in the United States and studied under the internationally renowned pharmaceutical chemist Professor Wang Shaomeng. In 2019, after completing postdoctoral research, Qin Chong chose to return to China instead of staying in the United States.
Learning to serve the country and realize the ideal of life is not only the ideal of Qin Chong, but also the entrustment of the Supreme Leader General Secretary to the youth of the whole country. On May 4th, 2014, General Secretary of the Supreme Leader visited Peking University. He emphasized that the value orientation of youth determines the value orientation of the whole society in the future, and the buttons of life should be buttoned from the beginning.
Qin Chong’s goal is to make a good medicine. As a student representative, Qin Chong, who was studying for a Ph.D. at Peking University at that time, not only listened to the general secretary’s teachings, but also reported his studies and future plans to him.

This conversation with the general secretary has strengthened Qin Chong’s desire to return to China to serve the motherland. In 2019, Qin Chong ended his postdoctoral research work in the United States. At the same time, Qingdao Municipal Government and China Ocean University also extended an olive branch to him. The two sides hit it off, Qin Chong returned to Qingdao, was hired as a Taishan scholar in Shandong Province, obtained a talent green card, and was selected as the first-level professor of young talents in China Ocean University.
Everything is difficult before it is easy. At the beginning of the project, the laboratory was in urgent need of a batch of expensive equipment. He found Dean Zhang of the School of Medicine.
The School of Medicine of China Ocean University has given Qin Chong great help and full freedom in human, financial, material and academic research. The start-up capital of 3 million yuan was quickly put in place, and the R&D team members were chosen by Qin Chong, all of which made him feel more practical. Academician Guan Huashi, one of the founders of modern marine drug research in China, and other old-timers often encourage and support the research and development work of Qin Chong’s team.
With the efforts of all parties, Qin Chong soon built a laboratory that reached international standards and began the research on degradation drugs targeting protein. His team members can be described as a group of scholars, including more than 20 doctors, 2 doctors, and more than 10 masters or masters, with an average age of less than 27 years old. At present, Qin Chong has led a team to tackle key problems in the fields of colorectal cancer, pancreatic cancer and nonalcoholic fatty liver, and it is progressing smoothly. Among them, there has been a breakthrough in the direction of colorectal cancer.
The research and development cycle of innovative drugs is long and difficult, and success and failure are normal. Like explorers, Qin Chong’s team struggled to find an exit in the dark. Although it is difficult, we should always remember the speech made by the Supreme Leader General Secretary in Tsinghua University — — "Life meets prosperity and shoulders heavy responsibilities", so it is duty-bound.
Run while you are young; Learn martial arts while you are young and serve the country and the people. In the prosperous times, today’s era is full of opportunities and gives young people new responsibilities. If the younger generation has ideals, skills and responsibilities, the country will have a future and the nation will have hope. We also see that the career development of these two scientific and technological talents has been helped by the government and schools. While we applaud the achievements and achievements of young talents, we also need to provide them with more such support, so that more young talents can display their ambitions, realize their dreams, and build the most beautiful country with the warmest heart.
