Mount Buzhou (不周山 lit. "Unrevolving Mountain") was an ancient Chinese mythological mountain which, according to old texts, lay to the northwest of the Kunlun Mountains, in a location today referred to as the Pamir Mountains. It is the mountain said to have supported the heavens, against which the Chinese water god Gonggong smashed his head in a fit of anger, requiring the goddess Nüwa to repair the sky. Nevertheless, once the spacer between the Earth and Sky was damaged, the land of China was permanently tilted to the southeast, causing all the rivers to flow in that same direction.
