The interest rate of the remaining amount after the minimum repayment is agreed as follows: the upper limit of the daily interest rate is 0.7 times 0.5% (the upper limit is 18.25%, and the lower limit is 0.7 times of 18.25%, that is, 12.775%, and the conversion formula is calculated according to the annual interest rate = daily interest rate *365). Without special notice, the daily interest rate standard defaults to five ten thousandths.
