University of Chinese Academy of Sciences, referred to as National Science and Technology University, is affiliated to China Academy of Sciences. Founded in 1978, formerly the Graduate School of China Academy of Sciences, it just changed its name this year. China Academy of Sciences has more than 100 institutes. If you are admitted to the graduate school of National Science and Technology University, you will study basic courses in Beijing in the first year, and go back to the graduate school to do research with your tutor in the second and third years. After graduation, the degrees of all graduate schools are unified. It used to be the Graduate School of Chinese Academy of Sciences, but now it is the National Science and Technology University. Probably this relationship, I just graduated from graduate school.
