About Sima Rong

Sima Rong, courtesy name Zihui (子徽), posthumously known as Prince Xiao of Liang (梁孝王), was the son of Sima Yi and his concubine Lady Zhang, and a younger half-brother of Sima Shi and Sima Zhao. Sima Yi, Sima Shi and Sima Zhao eventually became regents of the Cao Wei state during the Three Kingdoms era. Besides his heritage, Sima Rong was known for his involvement in the death of Jin official Zhou Chu, his association with his half-brother Sima Lun, and his relative mediocrity in the various positions he held in the Western Jin government during the reigns of his nephew, Emperor Wu of Jin, and his grandnephew Emperor Hui.
