Chuānzhōu

Chuanzhou was a prefecture in the country northeast of Chaoyang, on the frontier between the northern steppe and the settled lands of northeastern China. Under the Liao dynasty it was formed from Baichuanzhou in 951 and administered from Xiankang. Its military governor held the title of Changning, giving the prefecture a place in the Liao system of regional command. The name endured into the Ming period, though the political powers ruling the region changed.
