In 939, Xu Zhigao changed his surname back to his birth name of Li, and took a new name of Li Bian. His children also changed their names to Li, and Xu Jingsui thus took the name of Li Jingsui. Not long after, Li Jingsui's title was changed to Prince of Shou. In 942, when the senior statesman Song Qiqiu insisted on taking over the executive bureau, Li Bian had Li Jingsui yield the oversight of the executive bureau to him, and instead had Li Jingsui oversee the legislative (中書省, "Zhongshu Sheng") and examination (門下省, "Menxia Sheng") bureaus instead, but also having Li Jingsui's older brother Li Jingtong (whose name had been changed to Li Jing by this point) oversee all three bureaus. Shortly after, Song's close associate Xia Changtu () was involved in a corruption scandal, but Song initially did sentence him to death. Li Bian, in anger, personally ordered Xia's death. Song thus resigned his oversight over the executive bureau and was no longer meeting the emperor. Li Bian had to send Li Jingsui to his mansion to comfort him and promise to make him the military governor of Zhennan Circuit (鎮南, headquartered in modern Nanchang, Jiangxi) in order for him to come to the palace, upon which Song was given the Zhennan command.
