Gejiu

Gejiu is a county-level city and the former capital of Honghe prefecture, Yunnan Province, China. It is the site of the country's largest tin deposits and its main industry is mining.

To the south-west in this valley is Nansha, which lies directly below the town of Yuanyang. To the north-west lies Jianshui, and to the north Jijie. Mengzi lies 12 miles to the East. Originally a small mining settlement Gejiu was called Gejiuli. Under the Yuan (1206–1368) and Ming (1368–1644) dynasties the mining of silver was begun there. In the late 17th and 18th centuries, mining in Yunnan boomed, but tin mining in Gejiu did not develop until the second half of the 18th century. In the 1880s the city was created a subprefecture under Mengzi County, about 30 km to the east.

The town is located in a crater-like depression around a lake on top of a mountain. The main road enters the town from the north through a thin pass. To the east and west are steep cliffs.
