On 1st July 1941, Zeng Zhaolun, a chemistry professor of the Southwest Associated University, led a group of scholars and students to investigate the southwestern area of present day Sichuan Province (which at that time was split between Sichuan and Xikang). Zeng published two books, Dian Kang Dao Shang (On the way from Yunnan to Chuankang) in 1943 and Investigation of Daliangshan Yi District in 1945. The content of those books correspond with photographs in this collection.
No further information of Zehan Chen, the photographer, has yet been found, but some of his fellow students in this expedition group who were then undergraduates at Southwest Associated University became renowned scientists. For instance, Guangmao Dai later graduated with a PhD in chemistry at Indiana University, USA, was a chemist working in the USA and China. Shi'e Li studied in Copenhagen and the USA, and was a biochemist contributing to the study of cancer. Both of them are shown in the photographs.
