No matter how many CCB personal credit card master cards are handled in the name, the bill date is the same, and all credit card transactions are also recorded on the same bill, but they must be returned separately according to the card number when repaying.

Only one card can be successfully issued by the same card organization, the same category and the same level. For example, one Hong Kong, Macao and Taiwan tourist card gold card and one Hong Kong, Macao and Taiwan platinum card can be issued, but two Hong Kong, Macao and Taiwan gold cards cannot be issued. Therefore, for friends with multiple cards in their names, all the cards you hold are of different card types or card levels or card organizations.
