What are the outstanding generals in history who were not optimistic at first, but later became a blockbuster?

I want to talk about several ancient generals in China: Han Xin, Lu Xun and Wei Qing. These generals were not optimistic or even despised at first, but in the end they all changed their lives by their own wisdom, talent and hard work. Not only did he become a famous star, but his deeds have been passed down to this day, constantly inspiring future generations to work hard.

Han Xin's first days were particularly bitter and his legs were humiliated. He took refuge in Xiang Yu and was not reused. But took refuge in Liu Bang, but after a long period of patience and grasping the opportunity, he finally became a famous god of war. Lu Xun was a general of Dongwu during the Three Kingdoms period. When there was no general in Dongwu to command the military forces, he volunteered to resist Liu Bei's crusade, which caused heavy losses and made a name for himself.

Wei Qing was originally an illegitimate child, and his mother was unable to support him. His father's family regarded him as a slave and had a miserable childhood. Later, after being promoted by Emperor Wu of the Han Dynasty, he showed extraordinary talents, and his first expedition went smoothly. Later, he won many battles and became a famous star in the Western Han Dynasty. Even if these generals came from poor backgrounds, even if they were bullied and insulted, they finally became excellent generals by their own efforts.

They just explained a truth. Even if they have fallen into the abyss, even if they are unknown, even if no one is optimistic, as long as they are given a chance, they will prove that they are not sand but pearls. General Han Xin, Lu Xun and Wei Qing are more persistent and patient than those who have been promoted smoothly. Because they have experienced hardships, setbacks and contempt, they know how to seize opportunities and win with one move.
