Changzhi.

Changzhi is a prefecture-level city in the south-east of Shanxi, where the province meets Hebei and Henan. It has four urban districts and eight counties. The Taihang mountains close it on the east and the Taiyue on the west, and the middle is the Shangdang basin, the floor of an old lake; the three headwaters of the Zhuozhang River join inside the prefecture before the river leaves it eastward, and the Qin River rises in the west of the city. The old names were Shangdang and Luzhou, and a commandery was set up here in the fourth century BC. In 578 the Northern Zhou divided the commandery to create Luzhou. The city's protected buildings sit mostly in its counties rather than in its streets.
