《史记》: Ministers and conspirators said: "The Shao Emperor and Liang, Huaiyang, Changshan Wang, are not true filial piety. Lu later counted others, killing his mother, raising the harem, making Xiao Huizi After the thought, and the kings, to the strong Lv. This has been annihilated by Zhu Lu, and the establishment of the establishment, that is, long-term use, I am not class. It is better to regard the king of the sages stand.
After Lu’s death, the heroes and the royalists joined forces to destroy the Lu’s family and control the political affairs. On the one hand, Lv Hou’s ten-year powers have caused them to be suppressed and squeezed. On the other hand, they have also seen the power of the ruling. None of them have the ability and strength to swallow this mountain, but they don't want to lose the power to get it. They are even more afraid of retaliation and liquidation in the future. For various reasons, they need a suitable agent to stand in the foreground - a Liu surname, no The prince of Lu family background.
The essence of weak motherhood, filial piety and weakness is to facilitate the control of Chen Han and Zhou Bo and other Western Han ministers. When Emperor Wen of the Han Dynasty was in power, he was rewarded with Zhou Bo as the first. It can be seen from this that Zhou Bo’s credit is not to kill Zhu Lu, but more importantly, to support it.
In the eyes of everyone, Liu Heng seems to be a very suitable candidate: the son of Gaozu, who has nothing to do with Lu, the most important point is "weakness." Liu Heng’s weakness is manifested in two aspects: the remote land and unfavorable status determine his weakness in strength, and he is willing to stay in the country instead of moving to the prosperous Zhaodi to show his character weakness. So after some elimination, Liu Heng emerged from the water and became the final candidate of the new emperor.
