impudent response, although the text of the response was not recorded. With this apparent break in relations, Jing persuaded Shi Chonggui to arrest Liao's trade liaison officer at Daliang, Qiao Rong (), and seize all of property owned by the Liao liaison office. Further, all of the other Liao-authorized merchant officers within the Later Jin realm were seized and executed, and their property was seized. With the other officials pointing out that it was Liao aid that led to Later Jin's establishment, Shi released Qiao in 943, comforted him with kind words, and returned him to Liao. However, before Qiao's departure, Qiao went to bid Jing farewell. Jing, arrogantly, stated to him: As Qiao feared that Emperor Taizong would blame him for the loss of the Liao wealth, he flattered Jing and requested that Jing write his words down on paper. Jing had his secretary write down the words and give them to Qiao. When Qiao presented them to Emperor Taizong, Emperor Taizong was incensed, and therefore became resolute that he would attack Later Jin. He had the Later Jin emissaries detained at You Prefecture (幽州, in modern Beijing) and refused to see them himself. Even though Sang Weihan (who negotiated the original alliance between Shi Jingtang and Emperor Taizong) repeatedly suggested that Shi Chonggui revert to subservience to Liao to avoid a war, Jing repeatedly stopped Shi from doing so. 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. The second Liao thrust, led by Yelü Andu toward Hedong, however, was repelled by Hedong's military governor Liu Zhiyuan. Later Jin's prefect of Bo Prefecture (博州, in modern Liaocheng, Shandong), Zhou Ru (周儒), who was in secret
