石世
Shi Shi was Shi Hu's youngest son, by his third empress Empress Liu, the daughter of Han Zhao's last emperor Liu Yao. In 348, after Shi Hu had executed his second crown prince Shi Xuan () for having assassinated his brother Shi Tao (), he considered whom to make crown prince, and although Shi Shi was the youngest, Shi Hu's official Zhang Chai () was able to convince him that he needed to create a crown prince whose mother did not come from low birth. Empress Liu and Zhang then planned to control the government after Shi Hu's death.
