Dong Zhang
By late 926, An had begun to be concerned about two powerful military governors that Emperor Zhuangzong had commissioned prior to his death to govern the former territory of Former Shu—Meng Zhixiang the military governor of Xichuan Circuit (西川, headquartered in modern Chengdu, Sichuan) and Dong Zhang the military governor of Dongchuan Circuit (東川, headquartered in modern Mianyang, Sichuan), because Meng was closely related to Emperor Zhuangzong (as his wife was a niece of Li Keyong's and therefore a cousin of Emperor Zhuangzong's) and Dong was a favored general of Emperor Zhuangzong's. Meng was also acting fairly independently as the military governor of Xichuan Circuit, as he refused to yield tax revenues to the imperial administration. The official Li Yan () volunteered to serve as a monitor to the Xichuan army, believing that he could help curb Meng's exercise of authority, and An then sent him to Xichuan. Meng subsequently had Li executed, and another officer, Zhu Hongzhao, whom An sent to Dongchuan to serve as Dong's deputy military governor for a similar reason, fled back to Luoyang.
