典韋
In February 197, Cao Cao invaded Wancheng (宛城; present-day Wancheng District, Nanyang, Henan) in the north of Jing Province. Wancheng was the territory of the warlord Zhang Xiu, who immediately surrendered upon learning of Cao Cao's invasion. Cao Cao was pleased so he threw a party for Zhang Xiu and his men. During the party, Dian Wei stood guard behind Cao Cao, holding a giant battle axe whose blade was one "chi" long. Zhang Xiu and his followers did not dare to look up when they toasted to Cao Cao.
