Which schools are good, which famous teachers and which books can be read in the history of Qin and Han Dynasties!

I personally know that Renmin University, Shandong University and Peking University are all very strong. In addition, Huazhong Normal University, Fudan University, Zhengzhou University, Henan University, Jiangxi Normal University and Beijing Normal University also enroll masters in the history of Qin and Han Dynasties. Shaanxi Province was originally an important place to study the history of Qin and Han Dynasties, but I don't know what it was like in 13, and I can't recruit a master's degree in the history of Qin and Han Dynasties. There are too many famous teachers in the history of Qin and Han Dynasties. I don't know whether you are referring to the master of modern academic circles or the contemporary living scholars. If it is contemporary, you can search the members of the Qin and Han History Research Association, which includes most domestic scholars of Qin and Han history. We can learn about the works about the history of Qin and Han dynasties by means of the reference book A Summary of the Research on the History of Qin and Han Dynasties (Zhou Tianyou) and the paper A Study on the History of Qin and Han Dynasties in China in the Twentieth Century (Zhou Tianyou and Sun Fuxi).
