Sima Wei

[6] Late in his father's reign, on 22 December 289,[7] he was created the Prince of Chu and charged with the military commands of Jing Province (荊州, modern Hubei and Hunan).

One of those was Emperor Hui's wife Empress Jia Nanfeng, and she entered into a conspiracy with Sima Wei, among others, to overthrow Yang Jun.

Empress Jia, who had her husband easily under her control, had him issue an edict declaring that Yang Jun had committed crimes and should be removed from his posts.

Empress Jia, who had already resented Wei for having, during Emperor Wu's reign, suggested that he change his heir selection, also wanted more direct control over the government, and therefore resolved to plot a second coup.

In summer 291, Empress Jia had Emperor Hui personally write an edict, ordering for Sima Liang and Wei Guan removed from their offices.

On 13 October 301,[8] after Empress Jia's death, he was posthumously rewarded with the office of a general, and his son Sima Fan (司馬範), while not given the principality of Chu, was created the Prince of Xiangyang.
