Zhao Yanshou
Meanwhile, with no army coming to its aid, Zhang's army fell into desperate shape at Jin'an. Zhang's deputy Yang Guangyuan assassinated him and surrendered the army to the combined Khitan/Later Jin army. The Khitan/Later Jin army then prepared to head toward Zhao's army, and then to the Later Tang capital Luoyang. Apparently pursuant to Emperor Taizong's suggestion, Shi commissioned Sang and fellow staff member Zhao Ying chancellors (同中書門下平章事, "Tong Zhongshu Menxia Pingzhangshi"), with Sang also receiving the additional title of "Zhongshu Shilang" () and Zhao Ying "Menxia Shilang" (); Sang also continued to act as chief of staff. The Khitan/Later Jin army then crushed Zhao Dejun's army, forcing him and his adoptive son Zhao Yanshou to surrender. (Emperor Taizong subsequently took Zhao Dejun and Zhao Yanshou captive and had them taken to Khitan proper.) Emperor Taizong then decided to let Shi and his Later Jin army head toward Luoyang without the Khitan army (other than a small contingent), not wanting to disturb the Han Chinese of the region. As they parted each other, Emperor Taizong stated to Shi, "Liu Zhiyuan, Zhao Ying, and Sang Weihan are all great contributors to your establishment of the empire. Do not abandon them unless they had major faults." As Shi approached Luoyang, Li Congke, finding the situation hopeless, committed suicide with his family, ending Later Tang and allowing Later Jin to take over its territory.
