If the card has been collected and needs to be changed during use, you can bring the card and valid documents to the bank counter of CCB outlets to make changes, dial the customer service hotline to make changes, or log in to online banking to make changes (after logging in to online banking, select Credit Card-Credit Card Management-Personal Data Modification-Address Information Modification), enter the billing address to be modified, and verify the security tool to successfully modify the credit card billing address. )

If you have other specific questions, I suggest you call the customer service staff of the bank, hoping to help you.
