Tian Chengsi
Later in 775, when Tian Chengsi, the military governor of Weibo Circuit (魏博, headquartered in modern Handan, Hebei), had offended both the emperor and the military governors nearby, Emperor Daizong ordered a campaign be waged against him. Li Zhongchen and Li Zhengji were to attack Weibo from the south, and Zhu Tao, Li Baochen, and Xue Jianxun () were to attack from the north. Li Zhongchen initially put Weibo's Wei Prefecture (衛州, in modern Xinxiang, Henan) under siege, but after Li Zhengji withdrew from the campaign due to fears that his own soldiers would mutiny and a humble letter Tian sent him, Li Zhongchen withdrew as well. Emperor Daizong was subsequently forced to abandon the campaign against Tian.
