Li Baozhen
Emperor Daizong died in 779 and was succeeded by his son Emperor Dezong. In 780, Emperor Dezong officially made Li Baozhen the military governor of Zhaoyi. In 781, when Emperor Dezong, wanting to reassert imperial authority, refused to allow Li Weiyue to succeed his father Li Baochen as the military governor of Chengde or Li Na to succeed his father Li Zhengji as the military governor of Pinglu, Li Weiyue, Li Na, and Tian Yue the military governor of Weibo rose together against imperial forces. As a part of their operations, Tian attacked Linming (臨洺, in modern Handan), then defended by the Zhaoyi general Zhang Pi (). Li Baozhen sought aid from the imperial government, and Emperor Daizong sent the general Ma Sui the military governor of Hedong Circuit (河東, headquartered in modern Taiyuan, Shanxi) as well as a commanding general of the imperial Shence Army (), Li Sheng, to aid Li Baozhen. Together, Ma, Li Baozhen, and Li Sheng defeated Tian at Linming, forcing him to flee back to his headquarters at Wei Prefecture. In spring 782, they, along with Li Qiu () the military governor of Heyang Circuit (headquartered in modern Jiaozuo, Henan) again defeated Tian (who was then aided by forces from Pinglu and Chengde as well) at Huan River (洹水, flowing through modern Handan). It was said that, in the aftermaths of the battle, Tian's subordinate Li Changshun () was ready to surrender Wei Prefecture to imperial forces, but as Ma and Li Baozhen did not get along with each other, their progressed was slowed, and only after 10 days after Tian was able to flee back to Wei Prefecture and kill Li Changchun did the imperial forces arrive at Wei Prefecture, and they were unable to capture it. (Ma and Li Baozhen's grudge against each other had originated when Ma was the defender of Heyang; at that time, there was an occasion when Li Baozhen wanted to kill his subordinate Yang Shu () the prefect of Huai Prefecture; Yang fled to Ma, who not only allowed him to take refuge but further submitted a petition to the emperor to defend Yang.)
