As to which prince to choose to be the new emperor, some of the conspirators suggested that Liu Xiang, being the eldest "Di son" (嫡長子) of Emperor Gao's oldest son (thus the eldest grandson of Emperor Gao), was the obvious choice. However, most of the important officials disagreed with this suggestion. They were concerned that Liu Xiang's uncle Si Jun (駟均) was a dominating figure and that, if Liu Xiang were to become emperor, they would have a repeat of the Lü clan situation. They believed that Emperor Gao's oldest surviving son, 23-year-old Prince Liu Heng of Dai, was the better choice, because he was known to be filial and tolerant, and because his mother Consort Bo 's family was known to be careful and kind. They then secretly sent messengers to Prince Heng, inviting him to be the new emperor.
