Most credit cards of China Merchants Bank do not charge an annual fee, and a few cards will charge a certain fee because of their high cost. In addition, if the applied credit card has not been opened, the card will automatically become invalid after expiration, and China Merchants Bank will not renew the card for customers. If you don't need a credit card, you can also call the transfer service specialist of China Merchants Bank's credit card customer service hotline to cancel it for you. The cancellation is free.
