吴王
Xu Sheng was known for his confidence and fervent loyalty towards Sun Quan, as demonstrated in the incident when Xing Zhen (邢貞) came to confer the title "King of Wu" () on Sun Quan. In 220, Sun Quan became a vassal of the state of Cao Wei, which replaced the Han dynasty after the Wei founder, Cao Pi, forced Emperor Xian to abdicate the throne to him. Cao Pi sent Xing Zhen as an emissary to meet Sun Quan and confer the title "King of Wu" () on him. Xing Zhen behaved arrogantly in front of Sun Quan and incurred much anger from Sun Quan's subjects, including Zhang Zhao and Xu Sheng. Xu Sheng told his colleagues: "Isn't it humiliating to watch our lord submit to Xing Zhen and not be able to serve him with our lives and help him conquer Xu, Luoyang and Bashu?" Tears rolled down his face. When Xing Zhen heard Xu Sheng's remark, he told an aide: "It's obvious from the reactions of the subjects of Jiangdong that they won't remain subservient for long." Xing Zhen was right, because in 222, Sun Quan declared independence from Wei but continued ruling his domain under the title "King of Wu" before declaring himself emperor in 229.
