《资治通鉴·魏纪·魏纪七》
造成曹爽恶名声的那些事情，他都必定加以改正。终日兢兢业业，以安抚人民为先务，而且他们父子兄弟都掌握着兵权，是不容易被推翻的。 
爽之所以为恶者，彼莫不必改，夙夜菲懈，以恤民为先，父子兄弟，并握兵要，未易亡也。 
He has definitely corrected those things that had brought Cao Shuang a bad name. He worked hard all day long, and put appeasing the people first, and moreover, he and his father, brothers and sons all held military power, which was not easy to overthrow.
