Liu Ruyi_

Liu Ruyi, posthumously known as the "Suffering King of Zhao", was the only son of the first Han emperor Liu Bang's concubine Consort 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 as crown prince. Despite his half-brother Emperor Hui's protection, she finally succeeded in killing him in 194 BC.
