He Ning
In winter 941, both An Congjin and An Chongrong were preparing to launch their rebellions. Believing An Chongrong to be the greater threat, Shi prepared to take an army north from then-capital Kaifeng, preparing to engage An Chongrong as soon as he rebelled, leaving his nephew Shi Chonggui the Prince of Zheng in charge at Kaifeng. As he departed Kaifeng, the chancellor He Ning pointed out that An Congjin was also about to rebel. At He's suggestion, Shi Jingtang secretly left a number of blank, but pre-signed, edicts with Shi Chonggui, to allow Shi Chonggui to commission generals against An Congjin as soon as An Congjin launched his rebellion.
