What should I do if I receive a text message and go to the nearest police station for online education?

You need to go to the police station and ask if the message was sent by the police station.

Don't trust any text messages, which may be harassing text messages or encountering telecom fraud. If the short message is attached with a network link address, don't click Open, because this is probably a fraudulent website of criminals.

You can also study online security education at home. Network security is a comprehensive subject involving computer science, network technology, communication technology, cryptography technology, information security technology, applied mathematics, number theory, information theory and other disciplines.
