Dìnghú

Dìnghú was a county seat on the east bank of the Yellow River, where the river separates western Shanxi from Shaanxi, at the town of Mengmen in what is now northwestern Liulin. The Tang restored the county in 634 under Shizhou, and under the Song it belonged to the frontier garrison district of Jinning. In 1195 the Jin renamed it Mengmen County, and the old name faded. Mengmen lived on as a town on the Yellow River, drawing on both the water and the hills of the Shanxi bank.
