Qing Chinese paediatric face diagnosis chart

Wan shijia chuanguang si jiyao (Digest of Knowledge Handed Down by Ten Thousand Masters) - often abbreviated to Guang si jiyao - originally existed in a five-volume (juan) and a six-volume version. Only the five-volume version is known to be extant. It deals chiefly with male and female infertility, disorders and complications of pregnancy and childbirth, and illness in babies and infants. Juan 5 includes a supplement entitled Michuan jingyan xiao'er nafa (Secretly Transmitted Tried and Tested Paediatric Massage Techniques), illustrated with 22 diagrams.
