Meng Chang
In 934 (by which time Li Siyuan's son Li Conghou was Later Tang's emperor), Meng Zhixiang declared himself the emperor of a new state of Later Shu. He became deathly ill not soon after, however, and he, after entrusting his young son Meng Renzan (soon renamed Meng Chang) to Zhang Gongduo and a few other high-level officials and generals — the chancellor Zhao Jiliang and the generals Li Renhan, Zhao Tingyin, Wang Chuhui, and Hou Hongshi (侯弘實) — died. Meng Chang succeeded him as emperor. Meng Chang conferred on Zhang the honorary title of acting "Taiwei" (太尉).
