He received his M.S. degree in Mathematics in Fudan University in 1987, and got his Ph.D. degree in Information Science in Renmin University of China (The People’s University of China) in 2000. He translated many scholarly works in musicology, philosophy, history and library science, and compiled several books in library acquisitions and library cataloging. He was awarded by the State Council for his special contributions in library science. He also writes under various pen names, such as Mandarin Bookworm, Bookworm (书蠹精) and Sanniu (三牛), and sometimes uses Benjamin Gu (or Benjamin Kupên) as his English name. There are some variations of his name, including 구벤 (Korean), Pen Ku (Wade–Giles Romanization) and Бэнь Гу (Russian). Biography Ben Gu's grandfather was born in Suzhou, China, not far from Shanghai.

After entering high school, Ben Gu began to excel in pure mathematics and received one of the top prizes in Shanghai Municipal Mathematical Competition. He studied in the Department of Mathematics, Fudan University, and achieved excellent academic records every year. As a graduate student in the Institute of Mathematics, Fudan University, he focused his research on partial differential equations. His Master's thesis "Reflection of Singularities at Boundary for Piecewise Smooth Solutions to Semilinear Hyperbolic Systems" was published in the Journal of Partial Differential Equations. During this period, he began to be interested in the Humanities. In his university years, he also learnt several other languages, notably English, German, French and Italian. These languages became important tools for his later academic research and translation. In July 1987, he became a book selector in the National Library of China, and began to translate scholarly works in his spare time. During 1997-2000, he studied in Renmin University of China as a part-time graduate student, and focused his research on information sociology under the advice of Prof. Yu Chen. He received his Ph.D. degree in 2000. He wrote several articles and books on library acquisitions in the 1990s, conducted research in library cataloging since 2004, and has worked towards the internationalization of Chinese library cataloging
