177, claiming to be the police station, asked where my family lived.

It's probably fraud. Go to the local police station to check. According to relevant public information, similar fraud cases have occurred from time to time in recent years. Fraudulent gangs pretend to be the staff of the entry-exit department and the public security bureau, send text messages or make phone calls to the masses, falsely claim that passports or other information have been fraudulently used, etc., in order to verify that passports or passports have problems and ask for important information such as personal bank accounts. The purpose of criminals is to set up a set of tricks step by step to induce citizens to provide information such as bank cards or click on links on phishing websites to defraud money. Public security organs will not require citizens to provide personal information such as bank card numbers, nor will they require citizens to make cash transfers or online payments. Citizens should not trust this kind of information easily, let alone blindly dial the phone number left by the other party or click on the network link. They can contact the local public security department to verify and call the police in time.
