<正> WE introduced Yao medicine practitioner Qin Xunyun in the January issue. This month we give an account of our visit to Jinxiu Yao Autonomous County, home of the Yao people who formulated Yao medicine. The five Yao sub-groups-the Chashan, Pan, Hualan, Shanzi and Ao-all live in Jinxiu. After visiting the county five times noted sociologist Fei Xiaotong says, 'Jinxiu is the center for research into the Yao ethnic group.'
