Zhu Yougui
While the Yan campaign was going on, in late 912, Zhu Quanzhong was assassinated by his son Zhu Yougui the Prince of Ying, who thereafter declared himself the emperor of Later Liang. The major Later Liang general Zhu Youqian the military governor of Huguo Circuit (護國, headquartered in modern Yuncheng, Shanxi), refused to submit to Zhu Yougui, and instead submitted to Jin, seeking Li Cunxu's aid. When Zhu Yougui subsequently sent the general Kang Huaizhen () to attack Zhu Youqian, Li Cunxu went to Zhu Youqian's aid and repelled Kang's attack, forcing Kang to withdraw. (Zhu Youqian would subsequently return to the Later Liang fold after, in 913, Zhu Yougui's brother Zhu Youzhen the Prince of Jun overthrew Zhu Yougui in a countercoup and became emperor, but would yet later revert to Jin.)
