Shi Jingtang
Shortly after Shi Jingtang's being proclaimed emperor, the Later Tang army, trapped by the Khitan/Later Jin forces, surrendered after Zhang Jingda's deputy Yang Guangyuan assassinated Zhang. Emperor Taizong and Shi Jingtang prepared to advance south, toward the Later Tang capital Luoyang. Shi Jingtang was prepared to leave one son at Taiyuan to serve as the titular defender, and he called out all of his sons for Emperor Taizong to choose. Emperor Taizong chose Shi Chonggui, stating, "This large-eyed child can be it." Shi Jingtang thereafter left Shi Chonggui in charge at Taiyuan, giving him the titles of defender of the northern capital (i.e., Taiyuan), mayor of Taiyuan, and military governor of Hedong. Subsequently, as the joint Khitan/Later Jin forces approached Luoyang, Li Congke, finding the situation hopeless, committed suicide with his family, ending Later Tang. Shi JIngtang then entered Luoyang unopposed. Still, the realm was not calmed, and in one of the rebellions against Shi Jingtang in 937, the general Zhang Congbin () killed two more sons of Shi Jingtang's, Shi Chongxin () and Shi Chong'ai (). As another son of Shi Jingtang's, Shi Chonggao (), had died in childhood, all that were left of Shi Jingtang's sons at this point, other than Shi Chonggui, was Shi Chongrui (). Later in 937, Shi Jingtang summoned Shi Chonggui to then-capital Kaifeng, and made him an imperial guard general. In 938, he made Shi Chonggui the mayor of Kaifeng and created him the Prince of Zheng.
