Learn to protect themselves
When rescuing the fallen elderly, it is best to have a witness, pay attention to taking photos to retain evidence, and call the police when necessary. When catching thieves, we should prevent thieves and dogs from jumping over the wall and hurting people.
Pay attention to your ability.
If you find someone else falling into the water, if you can't swim, don't jump into the water to rescue them. You can shout, find a stick and call the police. When you find vicious cases such as robbery and murder, don't rush in when your mind is hot, but fight with your wits. The most important thing is to ensure your own safety.
