Xīshānyáng

Xisanyang was a Kam native chieftaincy in the Duliu River hills of southeastern Guizhou, with its seat at Dingshang in present-day Congjiang County. Under the Yuan its territory was called Xishan great dong and governed by the Tian family of Sizhou.

The Ming established the Xishan Yangdong native commandery in 1407 and placed it under Liping Prefecture in 1414. It survived the conversion of neighbouring Fulu-Yongcong into a county in 1441, but the Qing abolished the commandery in 1693. Downriver, Xiajiang became a sub-prefecture seat in 1771.
