Binding my mother's bank card with QQ stole more than 3000. Can my mother go to the bank to find out?

Yes, the bank card has a bound mobile phone number. If your mother has opened the mobile phone information, you don't have to go to the bank to find out, so I suggest telling your mother in advance, because if you don't say anything, if your mother asks, if your mother calls the police because the money in the bank card was stolen by the bad guys, it will be a big deal, so I suggest confessing.
