Guo Chongtao
In 925, Emperor Zhuangzong was planning to launch a major campaign to destroy Former Shu. He commissioned Li Jiji as the titular commander as its operations, with Guo Chongtao serving as deputy commander, in actual command of the operations. Before departing Luoyang, Guo, still thankful to Meng for having recommended him initially, recommended Meng as the prospective military commander of Xichuan if the campaign would be successful in conquering Former Shu. Later in the year, after Li Jiji and Guo were successful in capturing Former Shu's capital Chengdu and its emperor Wang Zongyan (Wang Jian's son and successor), thus destroying it, Emperor Zhuangzong summoned Meng to Luoyang and made him the military governor of Xichuan, also bestowing on him the honorary chancellor designation of "Tong Zhongshu Menxia Pingzhangshi" (), preparing him to send him to Xichuan.
