Our system will collect the remaining undistributed principal and the installment fee payable in the current period by installments, which will be included in the minimum repayment amount of the bill on the next billing date. The prepayment of the remaining installments is free of charge, and the received fees are not refundable (amortized fees are not refundable, unamortized fees are only charged 1 installment, and the rest are free).
