Gǔshàn

Gushan lies in the mountain country south of the Huang River in the eastern approaches to the Tibetan Plateau. An old settlement stood here in Han times, and the locality later belonged to the frontier territory of Shanzhou. In 1386 the Ming established Gushan Post under the Xining Garrison. The remains of its old fortified settlement recall the importance of this route through the eastern highlands, where travellers passed between the river valleys of Gansu and Qinghai.
