夏侯渊
In 216, the Han imperial court awarded Xiahou Yuan with an additional 300 taxable households in his marquisate, bringing the total number to 800. Subsequently, Xiahou Yuan led an attack on the Di and Qiang tribes of Wudu (武都; in present-day Longnan, Gansu) at Xiabian (), capturing over 100,000 "hu" (斛; a large unit of measurement) of grain. When Cao Cao led his forces to attack the warlord Zhang Lu in Hanzhong Commandery, Xiahou Yuan led all the military officers and nobles in Liang Province to meet Cao Cao at Xiu Village (). The Qiang and tribal chieftains were fearful of Xiahou Yuan whenever they attended meetings with Cao Cao.
