Baiyin
Baiyin (simplified Chinese: 白银; traditional Chinese: 白銀; pinyin: Báiyín; lit. 'White-Silver') is a prefecture-level city in northeastern Gansu province, People's Republic of China. Established in the 1950s as a base for mining non-ferrous metals, its mines are becoming exhausted in recent decades, requiring the city to reinvent its economy. Located around 60 km (37 mi) from Gansu's capital Lanzhou, it is part of the Lanzhou-Baiyin Economic Belt.
