Zhao Yanshou
The joint Liao/Later Jin forces (now enlarged with the remnants of the Later Tang army at Jin'an) then engaged another Later Tang army sent to combat it, commanded by Zhao Dejun the military governor of Lulong, at Tuanbo Valley (團柏谷, in modern Jinzhong, Shanxi), crushing it. Zhao Dejun and his son Zhao Yanshou fled to and tried to defend Zhaoyi's capital Lu Prefecture (). The Later Jin emperor sent Gao Xingzhou back to Zhaoyi, and when he reached Lu, he persuaded Zhao Dejun and Zhao Yanshou to surrender. With the Zhaos out of the way, nothing was left to block the Liao/Later Jin forces from advancing on the Later Tang capital Luoyang, and so, as Emperor Gaozu did so (Liao's Emperor Taizong opined that if he advanced on Luoyang with Khitan troops, the people would panic, and therefore chose not to), Li Congke and his family committed suicide, ending Later Tang. Emperor Gaozu entered Luoyang and took over the rest of the Later Tang realm. He allowed Gao to return to his post at Zhaoyi, and bestowed on Gao the honorary chancellor designation of "Tong Zhongshu Menxia Pingzhangshi" ().
