One person can apply for more than one CCB credit card, and the number is unlimited. \x0d\ At present, it is not stipulated that the same bank can handle multiple credit cards, and the same bank can handle multiple credit cards, but the credit limit is shared, that is, the credit card with the highest limit is the highest limit. \x0d\ In the case that the same bank holds multiple credit cards at the same time, the credit lines of multiple credit cards are the same, and the credit card with low credit line generally enjoys the available credit line of the credit card with high credit line. \x0d\ For example, if someone holds three credit cards of a bank with a credit limit of 30,000 yuan, then the credit limit used by the three credit cards together is 30,000 yuan. When one card overdraws 4,000 yuan, the other two cards can only overdraw 26,000 yuan.
