Cao Xiu

Cao Xiu (rōmaji: Sō Kyū) was a Wei officer as well as Cao Cao's nephew. He was hailed as a wonderful archer and the "stallion" of the clan. After being fooled by Zhou Fang's false defection, his health fails due to the shame and he dies, though before his death, he would succeed Cao Ren in becoming Wei's Commander-in-Chief.

Roles in Games
In the Dynasty Warriors series, he is usually the commander at the Battle of Shiting in which he is fooled by Zhou Fang, thinking the Wu officer would defect to Wei. In most games he always survives until the battles of Hefei Castle and Wuzhang Plains.

For Dynasty Warriors 4 at He Fei, if Wu manages to take Shi Ting, Cao Xiu will arrive to get revenge for his defeat. In Wei's scenario, saving Cao Xiu from Zhou Fang's ploy enables him to join the fight in Fan Castle.

Historical Information
Cao Xiu was a nephew of Cao Cao, whom he joined during the formation of the Alliance against Dong Zhuo. He was treated by Cao Cao as if he were his own son and led Wei's elite Tiger and Leopard Cavalry alongside Cao Chun and Cao Zhen. During Liu Bei's campaign against Hanzhong, Cao Xiu served as an advisor to Cao Hong. He suggested to fight Zhang Fei and Ma Chao head on when the former threatened to cut off Cao Hong's retreat route, seeing through the ploy and defeating them both, which led to the death of Wu Lan.

After Cao Cao's death, his successor Cao Pi promoted him to General who Guards the South and sent him south to the borders to Wu. He was made General who Conquers the East in 222 and followed Cao Pi on the campaign against Wu. Together with Zhang Liao and Zang Ba, he defeated Lu Fan at Dongkou, but had to retreat after reinforcements led by Xu Sheng, Sun Shao, and Quan Cong arrived. After Cao Pi's death, Cao Xiu became Great Defender-in-chief and led another campaign against Wu.

At Shiting he fell for a ploy by Zhou Fang and was heavily defeated and wounded. He escaped thanks to the efforts of Jia Kui and retreated. He sent a memorial to Cao Rui, pleading guilty for his misjudgment. Cao Rui forgave him and treated him with even more respect. Cao Xiu died shortly afterwards because of skin infections resulting from his wounds at Shiting and was posthumously named Marqius Zhuang ("robust marquis"). He had two sons, Cao Zuan and Cao Zhao.

Romance of the Three Kingdoms
In the novel, Cao Xiu shoots an arrow that hits Ling Tong's horse and knocks him down. Ling Tong would have been killed by Yue Jin if not for the aid of Gan Ning.
