Ma Zhongying
Ma Zhongying seized Hezhou and vanquished the forces of Ma Lin, who had been sent to recapture Hezhou from him. However, he was relieved by his commander—who was also his uncle—Ma Ku-chang, for acting without orders to take Hezhou. Ma Zhongying seized Gansu's capital from the Guominjun in April 1929 but was eventually defeated and expelled by them.
