Zhou Dewei
Originally an officer under the Later Liang, he defected to Later Tang and served under Li Cunxu (Emperor Zhuangzong of Tang). He helped Zhuangzong's generals Zhou Dewei and Yuan Xingqin in an attack on Youzhou, against the Later Liang general Liu Xun in modern Wei County, Handan. While waiting for assistance from later Tang general Li Cunshen, Xia and Zhuangzong were caught in ambush set up by Liu Xun and fought their way out, killing hundreds. Zhuangzong rewarded Xia with the privilege of using the imperial surname of Li. In another battle, Xia recognized Later Liang general Wang Yanzhang and rode out by himself and pointed his lance at Wang's neck. After the conquest of Later Liang, Zhuangzong sent Xia to Zhengzhou with the title of Jiedushi of Heyang.
