Hulü Guang
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.
