Meanwhile, An Chongrong the military governor of Chengde, who had viewed Shi's submissive attitude toward Liao as a sign of weakness, was himself considering rebelling against Later Jin. He entered into an alliance with An Congjin the military governor of Shannan East Circuit (山南東道, headquartered in modern Xiangyang, Hubei), who was similarly considering to rebel. He also continuously provoked Liao by intercepting its emissaries and killing them. In summer 941, he issued a declaration in which he called on Shi to renounce the peace agreement with Liao and attack it to recapture the territories and peoples that Liao had previously captured, but was not yet openly breaking with Shi. In response, Shi, under Sang Weihan's advice, headed to Guangjin — since then renamed back to Yedu — to prepare for a potential campaign against An Chongrong. Anticipating that An Congjin might rebel when he left Daliang, Shi, under the advice of He Ning, left his nephew Shi Chonggui in charge of Daliang with authority to immediately commission generals to act against An Congjin.
