An example of a father who was still alive when the founding emperor proclaimed himself emperor in history, Liu Bang. Liu Bang is a self-made emperor, and his father Liu Taigong is an ordinary farmer. Liu Taigong's other three sons are honest farmers, farming honestly. Liu Bang neither farmed nor engaged in other businesses. Liu Taigong despises this son so much that he scolds Liu Bang whenever he has the chance. Liu Bang proclaimed himself emperor and became the first emperor of the Han Dynasty. Liu Bang became the emperor, and Liu Bang's father Liu Taigong became the emperor's father. After Liu Bang proclaimed himself emperor, he not only received Liu Taigong from the palace, but also arranged a luxurious palace for Liu Taigong. Since then, Liu Taigong has lived a luxurious life. Liu Bang once challenged Liu Taigong at a banquet. Liu Bang took the opportunity of toasting to his father and jokingly said to him, "You used to scold me for not doing my job well, and I was very helpless. Few brothers have a future. You see, who is more promising among the brothers now? "
