You need to check it yourself. The bottom of the credit card is marked with "valid until month/year", which means "valid month/year" in Chinese, that is, the credit card is valid. Usually, if there is no long-term overdue or other things that need to be evaluated, the bank will issue a new card to the billing address of the credit card in the month when the credit card expires. After receiving the new card, the cardholder can activate the new credit card, and then the new card can be used normally, while the old card is invalid.
