司马颖
As Sima Ying continued to remotely control the government from his stronghold of Yecheng (鄴城, in modern Handan, Hebei) as both regent and crown prince, the officials in Luoyang tired of the situation. Later in 304, Sima Yue led them in a rebellion against Sima Ying's forces, and he took Emperor Hui with him on the campaign. After some initial hesitation, Sima Ying fought and defeated Sima Yue's forces, forcing Sima Yue to flee. Emperor Hui was captured and taken to Yecheng. Subsequently, however, Sima Ying was defeated by Wang Jun (王浚), the commander of the forces of You Province (幽州, modern Beijing, Tianjin, and northern Hebei) and fled to Luoyang without his troops. Sima Yong then seized control of the government and Emperor Hui, deposing Sima Ying from his position as crown prince and replacing him with another brother of Emperor Hui's, Sima Chi the Prince of Yuzhang. In late 304, he further had Zhang forcibly move Emperor Hui and Crown Prince Chi to Chang'an, under his firm control.
