Cao Yu
Before his death, Cao Rui had initially planned to exclude Sima Yi from the regency and instead appoint Cao Yu, Xiahou Xian (), Cao Shuang, Cao Zhao, and Qin Lang as the regents. However, two of his close aides, Liu Fang () and Sun Zi (), who were not on good terms with Xiahou Xian and Cao Zhao, managed to persuade him to not just exclude those two, but Qin Lang and Cao Yu as well, thereby simply having Cao Shuang and Sima Yi appointed as the regents instead.
