In the year 200, during the Battle of Guandu between Cao Cao and Yuan Shao, Xu Huang participated in the early skirmishes at Boma (白馬; near Hua County, Henan) and Yan Ford (延津; present-day Yanjin County, Henan), where he defeated the warlord Liu Bei – who had joined Yuan Shao after losing Xu Province – and Yuan Shao's generals Yan Liang and Wen Chou. He was promoted to Lieutenant-General (偏將軍) for his achievements, and later joined Cao Hong in eliminating rebels led by Zhu Bi (祝臂) at Yinjiang (氵隱 疆; southwest of present-day Xuchang, Henan).
