Yàngbèi

Yangbei lies west of the Cang Mountains on the Yangbi River. Its name appears in ninth-century records among the local kingdoms of the Nanzhao era and later belonged to a patrol district and a post station. The Bonan road passed through this mountain country on its way west from Dali. During the Hongzhi reign of the Ming, officials of Menghua and Yongchang joined in building an iron-chain bridge across the Yangbi, helping travelers cross the river.
