What if I meet the bad guys? How to deal with bad people?
Whether the bad guys are so big, whether they still carry knives, and whether they have accomplices around them, this is something you should consider quickly. Otherwise, your blind resistance will only lead to losses, even indifferent sacrifices.
If you feel that you can't beat him, you can slow down and delay as much as possible until the good people draw out their swords to help. Or escape to a crowded and safe place. If you can't get rid of him and get robbed or bullied by him, you should calmly write down his appearance and voice. Try to leave more clues and evidence for the later alarm. Don't provoke him when he is tied up, or he will stab you to death in a panic. If he wants money or a mobile phone, give it to him, or you may be stabbed several times and become disabled. That's not worth it. Money is a thing outside the body, and life is the most important thing.
If you are sure you can beat the bad guy and have a guy in your hand, give him a good beating and then call the police to take him away. Don't push too hard, or you'll end up with intentional injury and go to jail.
