司馬師
Xiahou Hui was a daughter of Xiahou Shang, a military general of the Cao Wei state in the Three Kingdoms period. Her mother was the Lady of Deyang District (德陽鄉主), a sister of the Wei general Cao Zhen. She married Sima Shi, who was regent of the Cao Wei state from 251 to 255. She bore Sima Shi five daughters but no sons. She was an elegant and intelligent woman who helped Sima Shi with his scholarship and his strategies. Xiahou Hui knew that Sima Shi had an evil ambitions and rebellious heart, so she was often considered an obstacle to the realization of the ambitions of Sima Shi's father, Sima Yi. As a member of the Cao clan, the clan that founded the state of Cao Wei, Xiahou Hui could start a conspiracy against her husband's family, which would easily lead to the fall of the Sima clan.
