Investigation Report on the Miao People of Western Hunan
Shu-sheng Ling and Yih-fu Ruey
Between the Spring and Summer of 1933, the authors went to Western Hunan to conduct field research on the Miao people, studying their living patterns, legends as well as their language and culture.
As the book title suggests, this is mostly a descriptive report. The authors not only make use of the first-hand results they obtained from the fieldworks, but also of other creditable sources from the past.
