Description：In 1976, in an ordinary educated youth center in a rural area of Northeast China, the league secretary Peng Tianyi was recommended as a worker-peasant-soldier student and was about to return to Beijing to attend university. However, at this turning point in his life, aerospace scientist Chu Zhongliang secretly handed over his lifelong research results to him for safekeeping. In order to protect his precious academic achievements, Peng Tianyi gave up his passionate first love and the prospect of being recommended for school. While the educated youth returned to the city on a large scale, Peng Tianyi continued to take root in the countryside. In order to promote agricultural reform, he debated with conservative forces and missed the college entrance examination. After returning to the city to work, he made drastic changes in the economic system reform, which caused rifts in his family. In order to stick to his original intention of strengthening the country and enriching the people, he gave up the opportunity to inherit his inheritance in the United States and settled down to the plain and arduous economics research. After countless sacrifices and struggles, the educated youth represented by Peng Tianyi have made great contributions to China's reform.
