周德威
Liu Shouguang, however, was not satisfied with the princely title under Later Liang suzerainty. In 911, he claimed the title of Emperor of Yan. Subsequently, Li Cunxu, who was by that time allied with Wang Rong and Wang Chuzhi the military governor of Yiwu, had Zhou Dewei command a major operation against the new Yan state. By late 913, nearly all Yan cities had fallen to the Jin army, except for You Prefecture. Liu Shouguang claimed that he would surrender to Li Cunxu if Li Cunxu personally arrived to accept his surrender, but when Li Cunxu arrived, Liu Shouguang again refused to surrender, under Li Xiaoxi's advice. However, Li Xiaoxi then himself surrendered to the Jin army and revealed the desperate state the Yan army was in. Li Cunxu then ordered a final attack, and the city fell. Liu Rengong, his wife, and his concubines were taken captive. Liu Shouguang tried to flee to Cang Prefecture (which was then defended by Liu Shouqi, who had become a Later Liang general), but was captured on the way there. (When he was brought back to You Prefecture, Liu Rengong and his wife both spat on him and stated, "Rebellious bandit! Look at what you did to our household!")
