I'm going to travel to Brazil in South America. What should I pay attention to when going there?

The first thing to do here is safety first! Be sure to nip in the bud, try not to go out at night, try not to carry a backpack when you go out, try to make people think you are poor, and keep a low profile! Keep a low profile. Your low profile index is directly proportional to your safety index. In case of being robbed, don't resist, don't scream, don't put your hands in your pockets, and it will be over if you are misunderstood. In short, it is generally no problem to break the bank and eliminate disasters and give whatever you want.
