In 200, Yuan Shao mustered an army boasting 100,000 in strength and declared to march on Xuchang, the base of his rival, Cao Cao. To ensure a safe crossing of the Yellow River, he intended to send Yan Liang to attack Boma (northeast of present-day Hua County, Henan) and set a foothold on the southern bank of the river, but his adviser Ju Shou warned him that Yan Liang was too frivolous to handle the responsibility alone. Yuan Shao thus sent Guo Tu and Chunyu Qiong to supervise Yan Liang's operation. Before Ju Shou was stripped of power, he was responsible for the whole army. Yuan Shao later divided Ju Shou's command between him, Guo Tu and Chunyu Qiong.
