In 887, when Zhu Quanzhong decided to turn against his former allies Zhu Xuan the military governor of Tianping Circuit (天平, headquartered in modern Tai'an, Shandong) and Zhu Jin the military governor of Taining Circuit (泰寧, headquartered in modern Jining, Shandong) (who were cousins to each other), he sent Zhu Zhen () and Ge Congzhou to attack Tianping's Cao Prefecture (曹州, in modern Heze); they captured it and killed the prefect Qiu Hongli (). They then engaged Zhu Xuan and Zhu Jin at Pu Prefecture, defeating Zhu Xuan and Zhu Jin, who fled barely alive. This started a war between Zhu Quanzhong and the Zhu cousins.
