Cao Huan
After Sima Yi's death, his eldest son, Sima Shi, assumed his father's authority up until his own death on 23 March 255, after which Sima Yi's second eldest son, Sima Zhao, took up his elder brother's position. On 2 May 264, when the Wei emperor, Cao Huan, enfeoffed Sima Zhao as the vassal "Prince/King of Jin", Sima Zhao went on to honour his father with the posthumous title "Prince/King Xuan of Jin". Sima Zhao died on 6 September 265, and his eldest son, Sima Yan, succeeded him in his position. By the next year, in 266, after Sima Yi's grandson, Sima Yan, usurped the throne from Cao Huan and established the Jin dynasty with himself as the emperor, he honoured his grandfather with the posthumous title "Emperor Xuan of Jin", with the temple name "Gaozu", and named his grandfather's burial place "Gaoyuan Mausoleum" ().
