Yang Guangyuan
Meanwhile, while Shi Jingtang was alive, he had lent 300 horses from the imperial guards corps to Yang Guangyuan the military governor of Pinglu Circuit (平盧, headquartered in modern Weifang, Shandong). Jing demanded them back. Yang became angry and believed that the imperial government was suspecting him, and therefore secretly summoned his son Yang Chengzuo () back to Pinglu's capital Qing Prefecture (), and then prepared to rebel. In spring 944, Yang rebelled, and Emperor Taizong led a Liao army south to support him. Shi Chonggui mobilized the Later Jin troops to counter the Liao and Pinglu troops, with Jing in charge of the overall operations. It was said that Jing, impressed with his own power, was insulting to the other generals, such that even the emperor was unable to curb him.
