Li Sizhao
In late 899, Zhu sent Ge to launch a punitive campaign against Liu, putting Liu's son Liu Shouwen under siege at Cang Prefecture (滄州, in modern Cangzhou, Hebei). In spring 900, Li Keyong sent Li Sizhao 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.
