Ji. He also commissioned Xu Jingsui the titles of Shizhong (), defender of the eastern capital (as Jinling became the Southern Tang capital, with Guangling becoming the eastern capital with the name of Jiangdu (), and mayor of Jiangdu. He had Xu Jingsui lead the officials who were assigned offices in Jiangdu back to Jiangdu. In 938, Xu Zhigao recalled Xu Jingsui to Jinling, to participate in the matters of the office of chancellors, overseeing the executive bureau of government (尚書省, Shangshu Sheng). When Yang died later in 938, it was Xu Jingsui that Xu Zhigao sent to attend to the funereal train. Xu Jingsui was overcome with grief, and those who saw him were touched. 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.

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. During Li Jing's reign Li Bian died in 943. Li Jing, as the oldest son, was expected to be the heir, and while he initially offered the throne to Li Jingsui instead, Li Jingsui earnestly declined, and Li Jing thereafter took the throne. He created Li Jingsui the greater title of Prince of Yan. Shortly after, Li Jing, believing that it was Li Bian's will that he pass
