사마의
One day, Zhuge Liang sent a woman's ornaments to Sima Yi to taunt him to come out and fight. Sima Yi felt enraged and wanted to attack Zhuge Liang, but Cao Rui denied him permission and ordered him to remain in camp. Cao Rui even gave Xin Pi his imperial sceptre (a symbol of the emperor's authority) and sent him to the Wuzhang Plains to keep an eye on Sima Yi. When Zhuge Liang taunted him again, Sima Yi wanted to attack the enemy, but Xin Pi used the authority of the imperial sceptre to order him to remain in camp.
