Data 1: Chinese deeds

While continuing to study mathematical theory, he tried to find a way to combine mathematics with industrial and agricultural practice. After a period of practice, he found that the overall planning method and optimization method in mathematics can be widely used in industrial and agricultural production, which can improve work efficiency and change the face of work management. Therefore, while giving lectures at the University of Science and Technology, he led students to promote the optimization method and overall planning method in industrial and agricultural practice.

At the beginning of 1964, he wrote to * *, expressing his determination to take the road of combining workers and peasants. In March of the same year 18, * * * wrote back: "Poetry and letters have been read. Top gun, congratulations. " He wrote "Brief Introduction and Supplement of Overall Planning Method" and "Brief Introduction and Supplement of Optimization Method", and personally led the teachers and students of China University of Science and Technology to some enterprises and factories to promote and apply "double methods" to serve industrial and agricultural production. "Go to Jianghan to fight the heat in summer and go to Songliao first frost in winter." This is a portrayal of his life at that time. 1965 * * * Write to him again to congratulate and encourage him to "work hard and serve the people, not the individual".

Information 2: Hua's story

Hua's grades in primary school were average, and his grades didn't improve much after entering middle school, but he had a soft spot for mathematics. The difference is that his homework is not a step-by-step imitation of the teacher's practice, but likes to "doodle" in the exercise book, which is the process we advocate for children to explore and practice by themselves. It can be seen that today's concept allows children to explore the benefits of their own thinking development. Encouraged by the discerning teacher Wang Weike, in Xiong Qinglai, Hua also set a shining example for young people to become self-taught. A diploma is directly proportional to one's ability within a certain range. However, sometimes, when we miss an opportunity to represent our abilities, we can make up for it through our efforts the day after tomorrow. Although such efforts require too much, let us remember his words that inspired future generations: "I am not afraid of difficulties and study hard. This is the most important experience for me to learn mathematics well."
