After installment payment, pay back the credit card every month, and the credit line will be released in installments, that is, your credit line will gradually return to your credit line. The credit limit cannot be increased in another installment payment period.

For example, if your credit line is 6,543,800 yuan, you will spend 80,000 yuan in installments, and each installment will be 5,000 yuan, then you will only have a credit line of 20,000 yuan in the first month after installment. Every time you repay 1 period, the credit card limit will be restored to 5,000 yuan, that is, the credit will be restored to 25,000 yuan in the second month, to 300 million yuan in the second month, and so on, until the position is repaid (fees and the like will also be shared with you in each period).
