李存勗
After Li Keyong's death, Li Kening initially took over the discipline of the army, and no one dared to create a disturbance. By contrast, the officers and the soldiers did not then respect the young (then 22) Li Cunxu, and they were constantly commenting about him. Li Cunxu, in fear, offered the command of the army to Li Kening, but Li Kening declined, pointing out that he was Li Keyong's lawful heir. Under Li Kening's and Zhang Chengye's insistence, Li Cunxu took the titles of Prince of Jin and military governor of Hedong.
