Yan Liang
In 200, Cao Cao had become Yuan Shao's main rival for domination of northern China. In the preparations for the clash, Chunyu Qiong sided with Guo Tu against Ju Shou, calling for a more aggressive strategy against Cao Cao. As a result, he was given command of a third of Yuan Shao's army along with Guo. In the spring of 200, he joined Guo Tu and Yan Liang in an attack on Boma, held by Cao Cao's general Liu Yan.
