晋出帝
At one point in 945, Shi fell seriously ill. During that time, there happened to be an occasion where Sang had sent a maidservant to greet Shi Jingtang's wife Empress Dowager Li, and part of the greeting stated, "Has the Emperor's younger brother, Chongrui, been studying well?" Shi Chonggui heard of this and discussed this with Empress Feng's brother Feng Yu (who was also a chief of staff), and Feng Yu thereafter accused Sang of considering deposing Shi Chonggui and replacing him with Shi Chongrui. As Li Shouzhen also disliked Sang, he, Feng Yu, and Li Yantao () thereafter suggested that Shi Chonggui remove Sang. Shi Chonggui agreed, and not long after, Sang was removed from his posts as chancellor and chief of staff, and made the mayor of Kaifeng. Zhao Ying, who was then the mayor of Kaifeng, was made chancellor, and Li Song was made chief of staff, to replace him.
