of the imperial guards. After chancellorship It was said that the demotion from chancellorship depressed Jing Yanguang, who was also beginning to realize that Liao's strength would eventually endanger both himself and the state. He began drinking heavily. Meanwhile, as the campaign that repelled Liao drained the imperial treasury, Shi Chonggui sent out 36 emissaries to the various regions of his realm to have the local governments extract wealth from the people forcibly. Jing's Henan Municipality (河南, i.e., the Luoyang region) was to submit 200,000 coins. Jing, wanting to extract more, offered 370,000 coins, but his assistant Lu Yi () rebuked him for benefitting himself at the people's expense, and he stopped. In 945, Emperor Taizong made another major incursion into Later Jin territory, advancing to the vicinity of Yedu (鄴都, in modern Handan, Hebei). During this incursion, as part of the overall Later Jing defense efforts, Jing took his position at Huliang Ford (胡梁度, in modern Anyang). After a series of attacks and counterattacks on both sides, the main Later Jin army, under the command of Shi's uncle by marriage, Du Wei, defeated the Liao army near Yangcheng (陽城, in modern Baoding, Hebei).

Shi, finding the demands insulting, cut off negotiations. In 946, Emperor Taizong laid a trap for Later Jing. He had Zhao Yanshou write to Du, offering to surrender Lulong Circuit (盧龍, headquartered at You Prefecture) to Later Jin. Shi's then-chiefs of staff, Li Song and Feng Yu, believed in Zhao's letter, and advised Shi to accept. Shi commissioned another army, with Du in command and Li Shouzhen serving as Du's assistant, to advance north. Once they entered Liao territory, however, Emperor Taizong's army was ready to face them. They tried to retreat, but were surrounded at Zhongdu Bridge (中度橋, in modern Baoding). During this crisis, Jing was, per Shi's orders, stationed at Heyang to prepare for emergency operations. However, Emperor Taizong was then able to persuade Du and Li Shouzhen to surrender their army. He then advanced quickly toward Daliang. Finding the situation hopeless, Shi surrendered, ending Later Jin. After Later Jin's destruction Even before
