What does it mean to call the police station for early warning?

Prevent fraud. The police station called for an early warning to remind you to be careful recently and not to be cheated. Because the anti-fraud center of the public security organ in your area detects fraudulent information or contacts you by telephone, it will inform the police station in the jurisdiction to call the person who receives fraudulent information. This process is called fraud to discourage telephone calls, which means to remind you not to transfer money indiscriminately, not to do part-time jobs indiscriminately, and not to believe the contents of telephone messages indiscriminately.
