Hello, bill installment refers to the period from the day after the billing date to the final repayment date when the cardholder applies for installment repayment of a certain amount of RMB consumption that has been booked (only once every 30 days). The minimum application amount is 500 yuan RMB, and the maximum application amount does not exceed 90% of the total RMB consumption in the bill (excluding cash withdrawal, installment payment and other transactions stipulated by the bank).
