Murong and Liu for their defeat. Murong responded, "I have met many opponents, but none is as difficult as Hou. Why do you not try to engage him and see." As Hulü and Zhang rode out to engage Hou, however, Murong warned them, "Do not cross the Guo River [(渦水)]." (Murong's troops and Hou's troops were by this point stalemated across the Guo River.) When Hulü challenged Hou by showing his bow and arrows but did not cross the Guo, Hou told him, "You came for glory, but I am trying to leave in fear of death. I am your father's friend. Why shoot at me? And how do you know not to cross the Guo? It must be Murong Shaozong who taught you." Hulü was unable to respond, and Hou subsequently had his subordinate Tian Qian (田遷) shoot and kill Hulü's horse, and Hulü was forced to withdraw. Hou then captured Zhang but released him, and both Hulü and Zhang fled back to Murong's camp. Murong then stated, "What have you seen now? Do not rebuke me." (In spring 548, Murong defeated Hou, who was forced to flee to Liang Dynasty. Historical records do not indicate whether Hulü contributed to the victory.) During Emperor Wenxuan's reign After Gao Cheng died in 549, his brother Gao Yang took over as regent, and in 550, he had Emperor Xiaojing of Eastern Wei yield the throne to him, ending Eastern Wei and establishing Northern Qi as its Emperor Wenxuan. Hulü Guang continued to serve as a general, and was created the Viscount of Xi'an. In 552, when Emperor Wenxuan made an attack against the Kumo Xi tribe (in the upper Liao River drainage area), Hulü accompanied him and contributed in the victory. Over the next few years, he served as a provincial governor on the borders with Northern Zhou, and was largely successful in border skirmishes, capturing a number of minor cities from Northern Zhou. During Emperors Fei's and Xiaozhao's reigns In 560, after Emperor Wenxuan died and was succeeded by his son Emperor Fei, Hulü was made the governor of the important Bing Province (并州, modern central Shanxi). Also in 560, Emperor Fei's uncle Gao Yan the Prince of Changshan, with support from, among others, Hulü Jin, killed the prime minister Yang Yin and took power. Later that year, Gao Yan's mother and Emperor Fei's grandmother Grand Empress Dowager Lou Zhaojun
