周德威
Later in 914, with Liu Shouguang in dire straits under siege by the Jin/Zhao/Yiwu army, Yang headed north with Liu Shouguang's brother Liu Shouqi (), pillaging Zhao territory. This failed to save Liu Shouguang, however, as his capital You Prefecture () fell to Li Cunxu later in the year, ending Yan. After Li Cunxu annexed Yan lands, he then headed south with Wang Rong, Zhou Dewei, and his cousin Li Sizhao the military governor of Zhaoyi Circuit (昭義, headquartered at Lu Prefecture) to attack Xing Prefecture. When Yang advanced to try to save Xing Prefecture, however, the Jin/Zhao army withdrew.
