A Yun-nan polity which the Chinese state considered to be a "native prefecture". It was centred on what is today Feng-qing in Yun-nan, PRC. It was bordered on the east by Da-hou (q.v.) and on the south by Wan Dian (q.v.) and Zhen-kang (q.v.). See Tan Qi-xiang (1982; 76). It is likely equivalent to Muang Chan.
