Mainlanders have set up credit cards in Hong Kong. What will happen if they don't return it?

1) You can't get a credit card without an address.

2) Even if there is proof of address, there is no proof of bank income.

3) You must have a bank account in Hong Kong.

4) Even if you have complete documents, the credit card loan amount will not exceed the total deposit in your account because you have mainland status.

5) Even if you don't want to repay the borrowed money and take all the money from the bank, the Hong Kong police will hand over your information to the mainland police, who will arrest you and transfer you to Hong Kong for trial. Therefore, you have a criminal record, and your application for foreign travel and immigration will be rejected in the future.
