Zhou Dewei
In 900, Zhu further had Ge command armies of four circuits (Xuanwu, Weibo, and two other circuits under Zhu's control—Taining (泰寧, headquartered in modern Jining, Shandong) and Tianping (天平, headquartered in modern Tai'an, Shandong)) to attack Liu Rengong's territory. Ge quickly captured Yichang's De Prefecture (德州, in modern Dezhou, Shandong) and put Liu Shouwen under siege at Cang Prefecture. When Liu Rengong sought aid from Li Keyong, Li Keyong responded by sending his officer Zhou Dewei and his nephew Li Sizhao to attack the Xingming region (which had fallen to Zhu earlier) to try to divert Zhu's forces. When Liu Rengong himself tried to lift the siege by engaging Ge, Ge defeated him. However, when weather turned against the siege army, and mediators were sent by Wang Rong the military governor of Chengde Circuit (成德, headquartered in modern Shijiazhuang, Hebei), Ge withdrew.
