As of 936, Later Tang was embroiled in internal strife, as then-emperor Li Congke was suspicious that his brother-in-law Shi Jingtang the military governor ("Jiedushi") of Hedong Circuit (河東, headquartered in modern Taiyuan, Shanxi), would rebel against him. At the advice of the imperial scholars Li Song and Lü Qi (呂琦), Li Congke considered entering an alliance with the Khitan to ward off the possibility that Shi would seek aid from Khitan. However, when another imperial scholar, Xue Wenyu (薛文遇), argued against it by predicting that Emperor Taizong would demand a marriage alliance, Li Congke changed his mind and never made the alliance proposal.
