Muscle man may be beaten by young people for two reasons. First, a muscular man must be muscular and healthy, but he is kind-hearted and never fights, so he doesn't know fighting skills and is good at hitting people. On the other hand, young people in society do nothing every day, idle, take pleasure in hitting people, hate their hands without considering the consequences, so he is good at fighting. It is not surprising that a strong man can't beat him. Second, there is only one strong man, and young people in society love to fight in groups, so they can gather several people to fight one person. So the strong can't beat them!
