Níngchāng

Ningchang was a county of Yizhou in the country west of the Liao River. Under the Liao it belonged to a district established from households attached to a princess of the ruling family. The county and neighboring Shun'an lay between the sites now known as Tayingzi and Ha'ertao. In 1318 the Yuan raised Ningchang to the status of a prefecture. Its history belongs to a borderland in which successive states governed communities under changing administrative names.
