唐明宗
In 913, by which time Liu Shouguang had declared himself emperor of an independent state of Yan and was subsequently under attack from the joint forces of Jin, Zhao, and Yiwu Circuit (義武, headquartered in modern Baoding, Hebei), Liu Shouguang sent Yuan north of the Yan Mountains to try to recruit reinforcement troops and encourage aid from the Khitan, as well to allow the warhorses to feed. Subsequently, the Jin general Li Siyuan (adoptive brother to Jin's prince Li Cunxu) attacked the region. The Yan general Gao Xinggui (高行珪) the prefect of Wu Prefecture (武州, in modern Zhangjiakou, Hebei) surrendered to Li Siyuan. When Yuan heard this, he counterattacked and put Wu Prefecture under siege. Li Siyuan came to Gao's aid, and Yuan withdrew. Li Siyuan gave chase, after eight battles in which Yuan was hit with arrows seven times but continued to battle, and was able to hit Li Siyuan with an arrow once, he ran out of strength and surrendered to Li Siyuan. Li Siyuan was impressed by Yuan's bravery, invited Yuan to a feast, and subsequently took Yuan into his army and made him an adoptive son.
