 The couple became estranged from each other when Xiahou Hui saw that Sima Shi had the intention of usurping the Cao Wei throne.Sima Shi also became suspicious of his wife because she was distantly related to the ruling Cao family, so he allegedly had her poisoned to death in 234.After the Jin dynasty (265–420) replaced the Cao Wei state in 265, the first Jin ruler Sima Yan (Emperor Wu), a nephew of Sima Shi, bestowed posthumous honours on many of his deceased relatives but refused to do so for Xiahou Hui.
