1. Collect evidence: Try to keep all evidence after being cheated, including chat records and transfer records. These evidences will play an important role in the subsequent legal proceedings.

2. Call the police: Once it is determined that you have been cheated, you should report the case to the police immediately. If the amount you are defrauded reaches the local fraud filing standard, the police will file a case for handling.

3. Seeking legal aid: After the investigation by the public security organ is completed, it will be handed over to the people's procuratorate, which will bring a public prosecution to the people's court and investigate the criminal responsibility of the criminal suspect according to law. The victim may file an incidental civil action.
