After Lü Hou's death, the eunuch Zhou Bo and The Chancellor Chen Pingren joined forces with some of the Liu clans to launch the Shulu War, crushing the Zhulu forces in one fell swoop and deposing the little emperor, who they believed was not the son of Emperor Hui of Han.
The throne is empty, so who to choose? Liu Heng actually did not have any merit in this, but he inherited the throne. There are two main reasons for this, the first is the result of mutual compromise between Chen Ping, Zhou Bo and Liu Zongfu. The second Liu Heng's reputation for generosity and benevolence is outstanding, but at the same time there is no foreign power.

At that time, in the LuLu War, the two brothers of Liu Bang's eldest son Liu Fei's family, Liu Xiang and Liu Zhang, were greatly contributed. At that time, Liu Xiang was the King of Qi, and he still had soldiers in his hands, and his strength could not be underestimated.
After the Rebellion of Zhu Lü was quelled, Zhou Bo and Chen Ping's ministers secretly selected an emperor. At that time, there were many people who supported Liu Xiang, and their own families had made meritorious contributions, and without him, they might not have succeeded.
Besides, Liu Xiang is not an outsider, he is the King of Qi, the grandson of Liu Bang, there is nothing wrong with succession, after all, in how to say that the throne has also been passed to the third generation, he is not inappropriate.
But Liu Xiang's strength was too great, and the key was that his uncle was not a good class, which made Chen Ping and Zhou Bo and others very jealous. The ministers were very afraid of foreign forces, and if there was such a thing as Lü Hou again, they would be in trouble.
Therefore, Chen Ping and Zhou Bo were not happy that Liu Xiang would succeed him, besides, Liu Xiang's power was not small, and after he ascended the throne, he naturally did not need Chen Ping and Zhou Bo, so Yu was public and private, chen Ping and Zhou Bo were unwilling.
So Liu Xiang is impossible, who to choose? Acting King Liu Heng.
Liu Heng had several advantages, first of all, he was the son of Liu Bang, Gen Zheng Miao Hong. Moreover, people have done a good job in the country of the country, and he has the ability to govern the country in an orderly manner.
Secondly, his mother Bo Shi is also very kind, and there is no one in her mother's family, there will be no phenomenon of self-reliance, and naturally there will be no monopoly of foreign relatives.
In the end, Liu Heng was generous and kind to others, and it was appropriate to choose such a person to be emperor. The most crucial point is that the king is the oldest and the whole country is indisputable.
