劉安
Liu An had two sons. The younger was Liu Qian (刘迁), who was born by his princess consort and thus became heir to Huainan, while the elder, Liu Buhai (刘不害), was born to a concubine. Liu An favoured Liu Qian over Liu Buhai and never viewed the latter as his son. Liu Qian never regarded Liu Buhai as his elder brother. According to Tui'en Ling (推恩令, "Order to Expand Favours"), Liu Buhai could become a marquess if Liu An carved a part of Huainan for him as his fief, but Liu An never did. Liu Jian (刘建), son of Liu Buhai, having realized that both he and his father had little chance to be a marquess, became so resentful that he accused Liu An and Liu Qian of a coup attempt. Finally, in a fate similar to his father, Liu An committed suicide in 122 BC after his plot was revealed.
