سيما يي
In response to the Shu invasion, the Wei general Sima Yi led his forces and another 20,000 reinforcements to the Wuzhang Plains to engage the enemy. After an initial skirmish and a night raid on the Shu camp, Sima Yi received orders from the Wei emperor Cao Rui to hold his ground and refrain from engaging the Shu forces. The battle became a stalemate. During this time, Zhuge Liang made several attempts to lure Sima Yi to attack him. On one occasion, he sent women's ornaments to Sima Yi to taunt him. An apparently angry Sima Yi sought permission from Cao Rui to attack the enemy, but was denied. Cao Rui even sent Xin Pi as his special representative to the frontline to ensure that Sima Yi followed orders and remained in camp. Zhuge Liang knew that Sima Yi was pretending to be angry because he wanted to show the Wei soldiers that he would not put up with Zhuge Liang's taunting, and to ensure that his men were ready for battle.
