Cao Shuang
During the same chain of events, Cao Shuang had Sima Yi appointed to the position of Grand Tutor under the guise of a promotion, and while the position was indeed an honourable one, it practically held no actual authority, and removed Sima Yi from the position of Intendant of the Affairs of the Masters of Writing, instead giving authority over the Masters of Writing to Cao Shuang.
