Xin was born October 6, 1950, in Sichuan Province, China. He began his college life when he was 23, but he made progress fast. He received his B.Sc. in 1977, M.Sc. in 1983 from Tsinghua University, supervised by professor Yu-qiu Long (a member of the Chinese Academy of Engineering). He later earned a Ph.D. from The Hong Kong Polytechnic University.

Xin served as deputy dean in School of Civil Engineering until his death.  He was author and co-author of numerous scientific publications, an editor, and was on the editorial board of the Journal of  Engineering Mechanics.  He served on the editorial board of the Journal of  Engineering Mechanics from 1997 and contributed to numerous professional activities in structural engineering.
