Unlike Xiang Yu, Liu Bang was born in a noble family and had no education as a celebrity since childhood. As an ordinary farmer, Liu Bang didn't learn a skill and work hard like others. He hangs out in hotels on the street all day and hangs out with some local ruffians. Old, no fertile land, no money, only a small pavilion. His father was very angry and scolded him. You might as well be a man next door with a big field. Later, Emperor Gaozu built Changle Palace and Weiyang Palace. He once pointed to the palace and said to his father, what am I compared to now? The ministers mocked his father. This made Liu Taigong look natural when he saw his son.
People say that Liu Bang is shameless, mostly because of the shameless degree achieved by Liu Bang's sentence "Give me a piece of cake". This story happened during the struggle between Chu and Han. Xiang Yu was worried that he would suffer in the long-term confrontation, so he shamelessly arrested Liu Bang's father, tied him in front of the two armies, and threatened to kill his father and cook him into a meat soup if Liu Bang did not surrender. Hearing this, Liu Bang said calmly that you and I are "about brothers", so my father is your father. If you really want to cook him, give me a piece. I don't know what Liu Bang's father's first reaction was when he heard this. He was rescued and sealed the emperor's father. Anyway, Liu Bang can't be a father and son. Shameless, there are limits.
Another reason is that Liu Bang is the son of heaven, the statue of the Ninth Five-Year Plan. His words and deeds, every move are in accordance with the standards of the country's top leaders. Liu Taigong has been a farmer for most of his life, but he is a nobody at heart. When Liu Bang met him, there must be many funny things and embarrassing things. Might as well disappear.
