司馬穎
After Sima Ying briefly served as crown prince in 304, he was forced to flee with his brother Emperor Hui to the capital Luoyang and was deposed by Sima Yong the Prince of Hejian. Many of his subordinates, including Ji and Gongsun Fan (公孫藩), deserted, and Gongsun eventually started a rebellion with the stated goal of restoring Sima Ying. Ji and Shi both joined the rebellion—and it was only at that time that Ji gave his friend the family name "Shi" and personal name "Le." After Gongsun was subsequently defeated and killed, Ji became leader of the rebellion and made Shi his key general—now with the goal of avenging Sima Ying, who was forced to commit suicide in 306. However, their rebellion, while briefly successful in capturing Yecheng in 307 and killing Sima Teng (司馬騰) the Prince of Xincai, ultimately was defeated in the winter of that year, and Shi instead joined Liu Yuan, an ethnically Xiongnu former Sima Ying subordinate who had by now declared independence from Jin and established his own state Han Zhao. Liu Yuan made him a general.
