周德威
Later in 910, Li Maozhen the Prince of Qi—one of the rival states to Later Liang—as well as two military governors under him, Li Jihui the military governor of Jingnan Circuit (靜難, headquartered in modern Xianyang, Shaanxi) and Liu Zhijun the military governor of Zhangyi Circuit (彰義, headquartered in modern Pingliang, Gansu)—sent emissaries to Li Cunxu, the Prince of Jin (another rival state to Later Liang), suggesting that they attack Dingnan together. Li Cunxu sent his general Zhou Dewei to join the Qi forces. The two armies put Dingnan's capital Xia Prefecture (夏州, in modern Yulin, Shaanxi) under siege. Li Renfu sought aid from the Later Liang imperial government, and Zhu Quanzhong sent the generals Li Yu () and Liu Wan () to aid Li Renfu. When Li and Liu reached Xia, the Qi and Jin forces lifted their siege and withdrew. For his holding out against Qi and Jin, Zhu bestowed on Li Renfu the titles of acting "Taibao" () and honorary chancellor (同中書門下平章事, "Tong Zhongshu Menxia Pingzhangshi").
