Tian Wang
After Shi Hu deposed Shi Hong in 334, he did not immediately give Princess Zheng a greater title, but after he claimed the "Heavenly Prince" ("Tian Wang") title in 337, he created her empress and created Shi Sui crown prince. Later that year, however, after discovering that Shi Sui, unable to stand his constant rebukes and whippings, had plotted to kill him, he killed Shi Sui and deposed Empress Zheng to the title of Duchess Dowager of Donghai. The empress title went to Du Zhu.
