by the chancellor Jing Xiang), Zhu Zhen continued to leave Duan in command. Subsequently, before Duan could start his operations, Li Cunxu made a surprise maneuver across the Yellow River around Duan's army, and directly attacked Kaifeng. Zhu Zhen, unable to resist and unable to flee, committed suicide.
