I don't know if this alarm is useful, you can try it! My sister was cheated of 300 yuan some time ago, and the police said that one was willing to buy and the other was willing to sell. At most, it was commercial fraud. But you are large, you can try! It's no trouble anyway. Just take your ID card to the police station and make a statement. But the police may laugh at you because they just laugh at my sister and say you can be fooled?
