In 926, by which time Tang had long fallen, and the emperor of central China was the
Later Tang emperor
Li Siyuan, Li Siyuan commissioned his adoptive son
Li Congke as the acting military governor of Huguo Circuit (護國, headquartered at Hezhong). Either at that time or shortly after, when Li Congke went to Hezhong to take over the circuit command, Fang Gao went to greet him on the road, and requested to serve on his staff. Li Congke was pleased with him and made him in charge of the guests in Li Congke's household. However, Fang (along with imperial scholars
Li Song and Lü Qi () did do what they could to dissuade Li Congke from an idea that he had that they believed would be disastrous—moving Shi from Hedong to Tianping Circuit (天平, headquartered in modern
Tai'an,
Shandong)—believing that Shi would rebel if he did so. In summer 936, by which time Lü was no longer imperial scholar, there was a night when Li Song had the night off, and Xue was on duty, attending to Li Congke. Xue took the opportunity to persuade Li Congke that Shi would rebel anyway, and that it was better to let him rebel now. Li Congke agreed, and therefore issued an edict moving Shi from Hedong to Tianping. Shi did in fact rebel, and thereafter, with aid from the Khitan, defeated Later Tang forces Li Congke sent against him and then approached the capital
Luoyang. Li Congke and his family committed suicide, ending Later Tang. == During Later Jin ==
