This grandfather is over 70 years old. 1965 was admitted to the Physics Department of Wuhan University. After graduation, he taught in three universities for more than 30 years. Grandpa also said that watching Gao Shu and selling eggs were the ways he used to spend his leisure time.

In uncle's time, it was not easy to get into college. Many families don't have this kind of family condition, and they don't have this kind of consciousness to train their children to learn from childhood until they enter the university. Presumably, this uncle's family conditions are relatively good, and his parents also have certain cultural self-restraint. Therefore, it trained college students who were very rare at that time.

In those days, people respected knowledgeable scholars. So teaching in a university is also a very serious matter. In such an environment, it must seem that he has been entrusted with some kind of mission, like when he was studying, to teach young people what he has learned all his life, to study hard and to teach rigorously. And because I can communicate with other scholars and students, I also enjoy it.

My uncle read the English version of the advanced mathematics book, which shows that my uncle's mathematics foundation is still relatively solid. Generally speaking, people who are good at mathematics have strong logical thinking ability. Combining with my uncle's major in physics, if a person is good at mathematics and physics, which are very important in the scientific field, then he will also be a potential scientific research talent. Not only that, at that time, my uncle's English level was still very good. Therefore, people will know the information, knowledge and culture of the English-speaking world earlier than many contemporary people. This is very useful for enriching one's mind.

Grandpa is also a restless man, because he didn't come out to set up a stall to do business because of the pressure of survival. Moreover, his income conditions should be good, otherwise he would not just sell eggs on the street to kill his leisure time. Moreover, the state attaches great importance to the cultivation of talents. It is said that the retirement salary of the older generation who went to work and teach in primary and secondary schools at that time was ideal. That's not to mention the uncle who has taught in the university for more than 30 years.
