Pi succeeded him and inherited his vassal king title as the King of Wei (魏王). Xu Huang continued to be heavily trusted by Cao Pi, and he was appointed General of the Right (右將軍) and enfeoffed as the Marquis of Lu District (逯鄉侯). In late 220, Cao Pi usurped the throne from Emperor Xian, ended the Eastern Han dynasty, and established the state of Cao Wei (or Wei) with himself as the new emperor. After his coronation, Cao Pi promoted Xu Huang from a district marquis to a county marquis under the title "Marquis of Yang" (楊侯). Later, Cao Pi ordered Xu Huang and Xiahou Shang to lead an army to attack Shangyong Commandery (上庸郡; in present-day northwestern Hubei). After completing his mission, Xu Huang moved to the garrison at Yangping County (陽平縣; present-day Shen County, Shandong), so his marquis title was changed to "Marquis of Yangping" (陽平侯). Cao Pi died in 226 and was succeeded by his son Cao Rui as the emperor of Wei. During that time, Xu Huang successfully repelled an invasion on Xiangyang by the Wu general Zhuge Jin. For his contributions, he was awarded another 200 taxable households in his marquisate, bringing the total number to 3,100. When Xu Huang became seriously ill later, he gave instructions that he was to be given a simple burial after his death. He died in 227 and was granted the posthumous title "Marquis Zhuang" (壯侯), which literally means "robust marquis". Xu Huang's son, Xu Gai (徐蓋), inherited his father's peerage as the Marquis of Yangping. After Xu Gai died, his son Xu Ba (徐霸) succeeded him as the next Marquis of Yangping. Cao Rui later divided their marquisate and awarded marquis titles to two descendants of Xu Huang. Appraisal Chen Shou concluded Xu Huang's biography in the Sanguozhi with a brief appraisal: In Romance of the Three Kingdoms Xu Huang is a character in the 14th-century historical novel Romance of the Three Kingdoms, which romanticises the events before and during the Three Kingdoms period of China.
