曹休
In 228, during the reign of Cao Rui, Jia Kui and Cao Xiu were put in command of an army to invade Wu. This led to the Battle of Shiting. Cao Xiu fell for a ruse by the Wu general Zhou Fang, who pretended to defect to the Wei side. However, Jia Kui found Zhou Fang's defection suspicious and maintained his guard. Although the Wu forces won the battle, Jia Kui managed to save Cao Xiu after his defeat and protect him while he retreated.
