Shídiàn

Shidian lies south of Yongchang in a basin surrounded by the hills of western Yunnan. Under the Yuan a native commandery was established here, and the name Shidian later came to be written with different characters. The Qing abolished the commandery in 1649 and created Pingyi Prefecture, moving its seat to a village by the stone bridge at Baochang. In 1770 a patrol office was established in the district under Yongchang Prefecture.
