Shi Hu
Shi Zun was a son of Shi Hu and his (then-)favorite, Zheng Yingtao, who also bore Shi Hu his oldest son, Shi Sui (石邃). After Shi Hu seized power after the death of his uncle and Later Zhao's founding emperor Shi Le in 333, he forced the new emperor Shi Hong to create him the Prince of Wei and all of his sons princes—and it was this time that Shi Zun was created the Prince of Qi. Shi Hu would seize the throne in 334, and after he declared himself "Heavenly Prince" ("Tian Wang") in 337, he changed the ranks of all of his sons except Shi Sui to dukes, and so Shi Zun became the Duke of Pengcheng. His mother Princess Zheng was created empress, while his older brother Shi Sui was created crown prince. Later in 337, however, Shi Sui would be executed for plotting their father's death, and Empress Zheng was also demoted in rank to Duchess Dowager of Donghai.
