In summer 942, Shi Jingtang fell seriously ill. He summoned the senior chancellor Feng Dao, and then had Shi Chongrui come out to bow to Feng, and then put Shi Chongrui into Feng's lap, intending to show that he wanted Shi Chongrui to inherit the throne with Feng guiding the young emperor. However, after Shi Jingtang subsequently died, Feng, in consultation with the imperial guard general Jing Yanguang, concluded that as the realm was not calm yet, an older emperor was needed, so they supported Shi Chonggui, who then took the throne.
