Li Shaohong
In 925, Emperor Zhuangzong wanted to launch a major attack to destroy Later Tang's southwestern neighbor Former Shu. He first requested Li Shaohong's opinion on the right commander for the army, and Li Shaohong recommended the former Later Liang general Li Shaoqin, who had flattered Li Shaohong. However, Guo opposed on the grounds that Li Shaoqin was wicked and had contributed to Later Liang's destruction, and also opposed Li Siyuan (on the grounds that Li Siyuan would be necessary to be available for defending against another potential Khitan incursion). Instead, Guo recommended putting Emperor Zhuangzong's oldest son Li Jiji in command. Emperor Zhuangzong agreed, and also made Guo Li Jiji's deputy, in actual command of the army.
