What you said above is that your maximum credit limit is 18000 yuan, and -4330 yuan means that this is an overpayment, which means that the 4330 yuan in your credit card is your own money. At this time, if you spend money by credit card, the amount you can swipe your card is 4330+ 18000 yuan. I don't know why there is so much money in your credit card. Credit cards let you use the bank money first!
