司马颖
Once Sima Ying became in effective control of the government, he deposed Crown Prince Qin and made himself crown prince instead, and he also deposed Empress Yang—the first of four times she would be deposed during a duration of two years. He became arrogant and extravagant, and the people became disappointed. Seeing this, Sima Yue decided to resist; he welcomed Empress Yang and Crown Prince Qin back to their positions, and, in Emperor Hui's name, set out to attack Sima Ying. His forces were defeated by Sima Ying's, and he fled, leaving Emperor Hui in Sima Ying's hands at Yecheng. Sima Yong's forces entered Luoyang and deposed Empress Yang and Crown Prince Qin again.
