When the bill is divided into installments, select a credit card and enter the bill division page, displaying the card number of the credit card you selected, the upper limit of the current division amount and the lower limit of the current division amount. It means that the maximum installment amount you can make in the current period is not higher than the upper limit of the current installment amount, and the minimum amount cannot be lower than the lower limit of the current installment amount. You can choose the amount you need to pay in installments from these two reference amounts.
