This is what I saw when I clicked on the cash installment on the credit card website of CCB. Let me show you the cut photos. If you have more than one CCB credit card, the quota is shared. If one of your credit cards is not enough, the other one will also be affected.

For example, suppose you have two AB cards, both of which have a quota of 30,000. Then the maximum amount that these two cards can overdraw together is 30 thousand, not 60 thousand. Similarly, the maximum installment amount is 30,000.

Suppose your A card applied for 20,000 cash installments and didn't use anything else, then the available amount of this card is 10000. Then if card B is useless, the available amount is only 10000, and the maximum cash installment amount that can be applied for is10000; On the other hand, if you apply for a cash installment of 25,000 yuan for card A and spend 5,000 yuan, then the available amount of this card is 0, which leads to the available amount of card B being 0. Of course, you can't apply for cash installment.
