Liu Bangben is just a pavilion in Surabaya. After Guangwu Uprising, Chen Sheng led 3000 people to revolt in Peixian County. In the end, Daqin was destroyed first, and then Xiang Yu became the founding emperor of the Western Han Dynasty. Zhu Yuanzhang completed the counterattack from beggar to emperor. At the age of 25, he took refuge and embarked on the road against Yuan. It took sixteen years to realize the ideal of "expelling Land Rover and restoring China" and establish Daming.
After two emperors from grass roots ascended the throne, they began a large-scale heroic purge. Liu Bang successively wiped out Peng Yue, Ying Bu, Han Xin and other princes with different surnames. The number and scale of Zhu Yuanzhang's massacre were even greater, and only a few of the founding ministers, such as Tang He and Mu Ying, survived. On the other hand, Li Si and Wang Jian, who helped Qin Shihuang accomplish the great cause of reunification, saved their lives and were highly valued.
This difference is caused by their personalities and origins. Liu Bang and Zhu Yuanzhang were not as vicious as the first emperor. They can't treat heroes with different surnames with a normal heart, and they are dismissed out of a vicious mentality. The monarch who came up from the bottom has a very strong sense of crisis in his heart. He is always worried that someone will covet his country. In order to get rid of future troubles, he will remove all uncertainties about his ability.
