Gao Xingzhou
In early 944, Emperor Taizong led a major invasion into Later Jin territory, and quickly reached Yedu. When Shi sent emissaries to the Liao camp to try to sue for peace, Emperor Taizong rejected the overture. Yang Guangyuan, then the military governor of Pinglu Circuit (平盧, headquartered in modern Weifang, Shandong), subsequently rebelled in coordination with Liao. Shi commissioned a number of generals to resist the Liao attack, and himself also commanded troops, and, when the generals Gao Xingzhou, Fu Yanqing, and Shi Gongba () were put under siege by Liao troops at Qicheng (戚城, in modern Puyang, Henan) and Jing, overseeing the operations against Liao, refused to launch a relief army, it was Shi Chonggui himself who led his army to the three generals' rescue. Because of the other generals' hatred of Jing's control of authority, Shi Chonggui used this incident as an opportunity to remove him from his chancellorship, and the senior official Sang Weihan was put in charge of the army overall operations, as his chief of staff ("Shumishi"). After the Liao forces were repelled and withdrew, Shi Chonggui sent the general Li Shouzhen against Yang, and subsequently, faced with certain defeat but with Yang unwilling to surrender, Yang's son Yang Chengxun () forcibly put Yang Guangyuan under arrest and surrendered. (Yang Guangyuan was subsequently secretly killed on Shi Chonggui's orders.)
