Li Zhengji
Li Zhengji was soon made military governor. He continued his alliance with the other military governors who sought "de facto" independence from the imperial government in order to pass the territory to their descendants, however, and as part of the alliance system he gave a daughter in marriage to Li Baochen's son Li Weicheng () and took a daughter of Li Baochen's as the wife of his son Li Na. By 775, however, both Li Zhengji and Li Baochen were displeased with another member of the alliance — Tian Chengsi, who had seized much of Xue Song's Zhaoyi Circuit (昭義, headquartered in modern Anyang, Henan) and merged it into his own Weibo Circuit (魏博, headquartered in modern Handan, Hebei) and who had offended both Li Zhengji and Li Baochen by looking down on him and by caning Li Baochen's brother Li Baozheng (), a son-in-law, to death. In 775, both Li Zhengji and Li Baochen submitted proposals to Emperor Daizong to attack Tian, and Emperor Daizong approved, mobilizing the armies several other circuits loyal to the imperial government (commanded by Li Zhongchen, Zhu Tao, and Xue Jianxun ()) as well to join Li Zhengji and Li Baochen in attack. The joint army initially were successful against Tian, causing Tian much apprehension, but soon began to fall apart, with Li Zhengji initially withdrawing his army after his army complained that Li Baochen's army was receiving more rewards than they were. Tian further sent messengers to flatter Li Zhengji and hinting that he would be willing to yield his land to Li Zhengji, thus causing Li Zhengji to hold off his attacks entirely. Eventually, after Tian was able to play Li Baochen off against Zhu, Emperor Daizong was forced to abandon the campaign against Tian and, at Li Zhengji's urging, permitted Tian to remain at his post.
