Most credit cards do not charge a production fee, but some cards will charge a production fee due to special production processes and other reasons.
When a China Merchants Bank credit card expires, customers can bring their ID card and bank card to any China Merchants Bank outlet, or apply for a card replacement through the professional version/public version of personal online banking. If you apply for card replacement through the self-service channel, you need to go to the issuing bank of the original card to get the new card.
