History of Shizuishan

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 control.
