Сыма Чжао
In 254, while Sima Zhao was at the capital Luoyang, advisors to the Wei emperor, Cao Fang, suggested that the emperor surprise Sima Zhao and kill him to seize his troops, and then use those troops against Sima Shi. Cao Fang, apprehensive, did not act on the suggestion, but the plot was still discovered, and Sima Zhao assisted his brother in deposing the emperor and replacing him with Cao Mao. In the aftermath of the removal of the emperor, the generals Guanqiu Jian and Wen Qin rebelled in 255 but were defeated by Sima Shi.
