Li Shi
Still, Emperor Wuzong was worried that the rivalry between Zhang Zhongwu and Liu Mian would interfere with the Zhaoyi campaign, and therefore (after the imperial emissary Li Hui was unable to moderate the strain between Zhang and Liu) soon transferred Liu to Yicheng Circuit (義成, headquartered in modern Anyang, Henan). The former chancellor Li Shi was made the military governor of Hedong, but soon, a mutiny led by Yang Bian () expelled Li Shi. In the aftermaths of the mutiny against Li Shi, Emperor Wuzong considered sending Zhang to attack Yang, but Li Deyu pointed out that, due to Zhang's and Liu's rivalry, Zhang might bear a grudge against Hedong Circuit in general and might kill excessively, so Emperor Wuzong did not send Zhang. (Yang's mutiny was soon put down by Hedong soldiers under the command of the eunuch monitor of the army, Lü Yizhong ().)
