李罕之
Around the new year 899, Li Keyong's subordinate Li Hanzhi the prefect of Ze Prefecture (澤州, in modern Jincheng, Shanxi) seized Lu Prefecture (潞州, in modern Changzhi, Shanxi), then turned against Li Keyong and submitted to Zhu. Li Keyong ordered Li Sizhao to attack Li Hanzhi, and Li Sizhao was able to immediately capture Ze and take Li Hanzhi's family members captive, sending them to Taiyuan. However, Li Keyong subsequently diverted Li Sizhao to try to aid Luo Shaowei the military governor of Weibo Circuit (魏博, headquartered in modern Handan), who was then under attack from Liu Rengong the military governor of Lulong Circuit (盧龍, headquartered in modern Beijing). However, as Liu was subsequently repelled by the Xuanwu generals Ge Congzhou and He Delun () (as Luo also requested aid from Zhu) before Li Sizhao could arrive in Weibo territory, Luo again cut off relations with Hedong, and Li Sizhao withdrew.
