Taihang Mountains
The city stands at the edge of the North China Plain, which rises to the Taihang Mountains to the west of the city, and lies south of the Hutuo River. From west to east, the topography can be summarised as moderately high mountains, then low-lying mountains, hills, basin, and finally plains. Out of the eight east–west routes across the Taihang Mountains, the fifth, the Niangzi Pass, connects the city directly with Taiyuan, Shanxi.
