晋出帝
In 944, the Khitan Liao dynasty's Emperor Taizong—whose support had been instrumental in Shi Jingtang's establishment of Later Jin but whose relationship with Shi Chonggui had become inimical—invaded Later Jin. Li Shouzhen was one of the Later Jin generals sent to resist the invasion. When the Liao general Yelü Mada () tried to attack Shi Chonggui himself directly during the campaign, Li Shouzhen intercepted and defeated him. After the end of that campaign, Shi, while retaining him as discipline officer, also made him the military governor of Taining Circuit (泰寧, headquartered in modern Jining, Shandong).
