In summer 291, Empress Jia instructed Emperor Hui to write an imperial edict to Sima Wei, ordering him to have Sima Liang and Wei Guan removed from their offices. His forces thereby surrounded Sima Liang and Wei Guan's mansions, and while both men's subordinates recommended resistance, each declined and was captured. Against what the edict said, both were killed – Sima Liang with his heir Sima Ju () and Wei Guan with nine of his sons and grandsons. After Empress Jia, concerned about Sima Wei's power, then falsely declared that the edict was forged by Sima Wei and had him executed, Wei Guan was posthumously rehabilitated and restored to the status of a duke.
