If the expired credit card can no longer be used, the bank will reactivate the new card and then need to reactivate the credit card to continue using it. The new credit card limit and points will continue the previous card.
Agricultural Bank of China's credit card is valid for three years, and you can see it by paying attention to the information on the card surface. If there is anything you don't know, you can call the customer service number of China Agricultural Bank at 95599.
If you have other specific questions, I suggest you call the customer service staff of the bank, hoping to help you.
