Why did Xiao He, Han Xin and Sean follow Liu Banggan?

Sean is obviously a man with feelings. Sean 16 years old, South Korea was destroyed, but at the age of 32, he was still engaged in the assassination of Qin Shihuang. 16 The closest person to Sean in modern times is the Saudi royal bin Laden. For Sean, money and power are really not the primary goals. Sean's primary goal is to restore South Korea, and then assist the king of South Korea. Therefore, after the collapse of the Qin Dynasty, Liu Bang was obviously the second most powerful vassal, and Sean chose to leave and return to Wang Han. If Wang Han had not been killed by Xiang Yu, Sean would have been forced to defect to Liu Bang and become prime minister for life.
