If you are cheated online, you should report to the local network security supervision department in time, or log on the network security supervision and reporting website of the Ministry of Public Security to report, or you can report to the local police station.
 The best evidence to keep before reporting: the perpetrators of online fraud cases generally contact the victims indirectly through the media.
 First of all, the victim should keep all the evidence and transaction records. It is better to have the transaction records of the bank, as well as the online chat records, and your contact information with the other party.
 If conditions permit, you can ask people who can see the computer to help you find their IP address, so that the alarm will be more secure.
