This 1 1 professor belongs to the emperor. Yu Pingbo, Yao Yao, Fu Ying, Zhou Peiyuan, He Lin, Ma Yinchu, Tang Yongtong, Feng Youlan and Ding Feng are all "bigwigs" of Peking University, while Xu Cai and Chen Yuan work in Beijing Agricultural University and Beijing Normal University respectively. The account here is to restore the old "landscape" according to the records of official materials and a large number of original files at that time.

This 1 1 professor's fate reflects the fate of intellectuals in China, which embodies the tragedy of China's education and China's culture and is also a scene of China's historical tragedy.
