李罕之
In 890, when Emperor Xizong's brother and successor Emperor Zhaozong, at the instigation of the chancellor Zhang Jun, as well as Zhu Quanzhong, Li Kuangchou the military governor of Lulong Circuit (盧龍, headquartered in modern Beijing), and Helian Duo the military governor of Datong Circuit (大同, headquartered in modern Datong, Shanxi), announced a general campaign against Li Keyong, one of the prongs of the imperial/Xuanwu/Lulong joint attacks at Heyong was aimed at Li Hanzhi at Ze Prefecture, and as part of the announcement, Emperor Zhaozong stripped Li Hanzhi, as well as Li Keyong, of all offices and titles. Li Keyong sent Li Cunxiao to aid Li Hanzhi; Li Cunxiao, after capturing Zhang Jun's deputy Sun Kui () in a surprise attack, defeated the Xuanwu forces sieging Ze Prefecture, forcing them to withdraw. After Li Keyong subsequently defeated Zhang's main forces, Emperor Zhaozong was forced to exile Zhang and fellow chancellor Kong Wei in 891 and restore Li Keyong's and Li Hanzhi's offices.
