Li Sizhao
In late 899, Zhu sent Ge to attack Liu Rengong the military governor of Lulong Circuit (盧龍, headquartered in modern Beijing), putting Liu's son Liu Shouwen the military governor of Yichang Circuit (義昌, headquartered in modern Cangzhou, Hebei) under siege at Yichang's capital Cang Prefecture (). In spring 900, Li Keyong sent Zhou with a 5,000-men cavalry force, and then had Li Sizhao follow up with a 50,000-men force to attack Xing and Ming Prefectures to try to relieve the pressure on the Lius. Subsequently, though, Zhu recalled Ge, as Wang Rong the military governor of Chengde Circuit (成德, headquartered in modern Shijiazhuang, Hebei) mediated the dispute, and Ge's army was also itself stalled by rainstorms. By that point, Li Sizhao had captured Ming Prefecture. Zhu sent Ge against Li Sizhao, and subsequently arrived himself with reinforcements. Li Sizhao withdrew, but suffered substantial losses.
