As a bystander, I warn you to pay attention to this matter The other party knows you by knowing your mobile phone number, and the person who knows your mobile phone number specifically targets you. One is the phone number dialed by the other party. If it's two, it's easy to say. If you suspect it's one, be on your guard! You can mention it to some people you doubt intentionally or unintentionally, and observe the other person's look carefully. This time depends on perception. If it is the second one, I will give you four suggestions.

1: (direct method) Change the mobile phone number.

2. Open a QQ to add him, get acquainted with him first (if he is not a good person, pretend to be a rogue) and then cheat him slowly. Don't worry and don't be careless. You should make up a story about your identity first. When he asks you, he will say, be mentally prepared and don't tell the truth at all! Then we'll do it.

3. Ask him first that he is the owner of the mobile phone number. He is not afraid to tear his face or call the police, but don't take the money to call the police, otherwise it will be difficult to find it.

I wish you success in your work and get out of hot water as soon as possible! You have to believe in yourself, justice will win! ↖(^ω^)↗

4. Open the blacklist or green channel and call the firewall.
