I received several spam messages not long ago. Today, a man called me with a strange number and said he was a policeman.

Liars may use this information to continue to defraud or sell information. If you receive spam messages or fraudulent phone calls like this, you can call the customer service hotline or log in to the Internet lobby, send text messages and other related channels to make a complaint. Ordinary policemen don't call the masses. If you assist in handling a case, you need to go to the public security department to make a record, instead of just calling to handle the case. It is recommended to be vigilant, there are many tricks for scammers.
