马家军
Shizuishan used to be a center of local trade and eventually became a mining town. In 1934, Shizuishan was occupied by the army of warlord Sun Dianying during his attempt to conquer Ningxia from the Ma clique. Sun set up a rival provincial government in the town, but he was eventually defeated by Ningxia's official governor Ma Hongkui. Shizuishan was consequently returned to Ma's control.
