Fu Zuoyi
With the Anti-Japanese Allied Army under Fang Zhenwu and Ji Hongchang considerably reduced by Song's activities, Fang Zhenwu as the new commander-in-chief ordered the army east to Dushikou. Some of the subordinates of Ji Hongchang attempted to move west to Ningxia via Suiyuan. However Fu Zuoyi and Zhang Lingyun pursued and blocked them east of Ertaizi, forcing them east to join Fang Zhenwu at Dushikou.
