What would you do if you saw someone sneaking around?

When someone else is being stolen, you can subtly show that you know the stolen person, or remind him to stop. If you are stolen, the protection action is effective. If there are many people, you can say it directly (don't call the thief)

Hehe) attract the attention of people around you.

You can also record it on your mobile phone as evidence. Stop it when there is no danger, for example, let many people around you see the thief's behavior and let everyone catch the thief together. If there are few people in the car, try to follow him and call the police.
