Zhu Miaosheng: I later went to Hebei to attend primary school. 1965, I graduated from China University of Science and Technology, majoring in nuclear physics, and volunteered to participate in the research and development of atomic bombs in Qinghai under difficult conditions. Later, he returned to Beijing and worked in Beijing Hospital until his retirement (engaged in the application and research of physics in medicine), with the title of chief physicist. I am called "Professor of Physics at Peking University" on the Internet, but I have never worked in Peking University at all.
