according to the inquiry of credit card network, the CCB credit card will be invalid about 3-5 years after it is issued. Moreover, in this case, CCB will not replace the cardholder with a new card when it expires. According to the requirements of CCB, the new Longka credit card after October 1, 216 will be controlled by CCB within 18 days from the date when the cardholder activates the credit card. Once the cardholder is controlled, he can't make consumption and cash withdrawal, but can only handle counter business.
