Píngchádòng

Pingchadong was a hereditary Tujia cave chiefdom in the Wuling mountains, in present-day Xiushan. Its Yang chiefs traced their ancestry to the Yang of Bozhou and had been enfeoffed by the Sizhou chiefdom.

From 1375 Pingcha and three sister cave offices were supervised by the Youyang Pacification Commission. The hereditary office survived under the Qing until the court's administrative reforms converted it into Xiushan County in 1735. In 1736 the area was incorporated into the new Youyang Independent Prefecture.
