定军山
Xiahou Ba's parents were important figures in Cao Wei; his father, Xiahou Yuan, had fought alongside his distant cousin and founder of Wei, Cao Cao, since the start of the civil war, and was one of the most trusted of Cao's generals, while Xiahou Ba's mother was a sister-in-law of Cao Cao. After Xiahou Yuan was killed at Battle of Mount Dingjun in 219 at the hands of Shu general, Huang Zhong, most of his troops were placed under the command of Zhang He upon advice from Guo Huai, while his private militia and guards were succeeded by his five sons. Xiahou Ba displayed great hatred for Shu, and vowed revenge for his father. In 220, Xiahou Yuan's eldest son Xiahou Heng was given his own marquisate and marquis title, so Xiahou Ba inherited his father's marquis title with a stipend of tax revenues from 800 taxable households.
