Liu Ruyi (208 – c.January 194BC[1]), posthumously known as the "Suffering King of Zhao" (趙隱王, Zhào Yǐnwáng), was the only son of the first Han emperor Liu Bang's concubineConsort Qi. He was a favorite of the emperor and appointed king or prince of Dai and Zhao, but loathed by his stepmother, the Empress Lü Zhi, as consort Qi had attempted to persuade Liu Bang to have Liu Ruyi replace Liu Ying (Lü's son) as crown prince. Despite his half-brother Emperor Hui's protection, she finally succeeded in killing him in 194BC.
^According to volume 12 of Zizhi Tongjian, Liu Ruyi was poisoned in the 12th month of the 1st year of Emperor Hui's reign. This corresponds to 31 Dec 195 BCE - 28 Jan 194 BCE in the proleptic Julian calendar.
