Gǔyǒng
Wadian lay northeast of Tengchong, among the wooded valleys of the western Yunnan mountains. The Ming established a native commandery here in 1427, placing it under the military administration of Jinchi. In 1522 it was assigned to Yongchang Prefecture. Its position in the highlands put it near routes between Tengchong and the Nu River, where mountain communities and the authorities at the frontier town maintained long-standing connections.
