He was the introductory teacher of Cheng Qianfan, a master of Traditional Chinese Studies, and One of the founders of Chinese Library Science, Liu Guojun.
Liu Guojun (1899~1980), Zi Hengru, a native of Nanjing, Jiangsu Province, graduated from Jinling University and received a doctorate in philosophy from the University of Wisconsin. Mr. Liu's 37-year-old book "Chinese Book Classification Law" is one of the representative works of China's new library science movement, and it is also an academic product that integrates the traditional classification method of Chinese library buildings with the modern classification method of Western library science.
Mr. Liu Guojun is not only proficient in the study of book catalogs, but also good at edition proofreading. Mr. Liu Guojun is familiar with the handover of the ancient Chinese classics and has a very in-depth study of the changes in the history of ancient Chinese book printing. Mr. Liu Guojun has long been the head of the library department of Peking University, because of the great influence of his Chinese book classification law, and in 1958 he was forced to make an open self-criticism at Peking University.
When Cheng Qianfan (1913-2000), a professor of the Department of Chinese of Nanjing University, studied at Jinling University in his early years, the courses of bibliography were taught by Liu Guojun, who was selected to listen, and Cheng Qianfan's first university paper was an assignment in Mr. Liu Guojun's class, which was recorded in Cheng Qianfan's memoirs "Sang Yu Reminiscences" in his later years.
