For the platinum card, it is a higher-level card in the bank credit card, a credit, and also your own wealth. Only when it meets the requirements of the bank will it be handled. The face of a platinum card is different from that of an ordinary credit card, and the bank has treated it differently when issuing the card, so the platinum card cannot be directly converted into an ordinary card.

If you need an ordinary card, you can only return the platinum card and apply for an ordinary card again.
