The people's court shall support the lender's request to the borrower to pay interest at the agreed interest rate if the interest rate agreed by the borrower and the borrower does not exceed the annual interest rate of 24%.

The interest rate agreed between the borrower and the borrower exceeds the annual interest rate of 36%, and the interest agreement in excess is invalid. The people's court shall support the borrower's request to the lender to return the interest paid in excess of 36% of the annual interest rate.
