Cao Ren

Cao Ren, courtesy name Zixiao, was a military general serving during the late Eastern Han dynasty of China under the warlord Cao Cao, who was also his older second cousin. He continued serving in the state of Cao Wei – founded by Cao Cao's son and successor, Cao Pi – during the Three Kingdoms period. He played a significant part in assisting Cao Cao in the civil wars leading to the end of the Han dynasty. He was appointed as the Grand Marshal (大司馬) when Cao Pi ascended the throne, and was also credited by the latter for the establishment of Wei. However, Cao Ren was also once derided as a mediocre commander by Zhu Huan, a general from Wei's rival state Eastern Wu.
