Hàomén

Haomen lies in a high valley of the eastern Qilian Mountains, on the river of the same name. The Haomen is a reach of the Datong River, which flows eastward toward the Huang and ultimately the Yellow River. Marshes lie in its higher reaches, while the valley around Haomen provides land for cultivation and grazing. Mountain ridges rise on either side, separating this basin from other valleys and from the dry Hexi Corridor farther north.
