The down payment balance means that if you pay 50 yuan now, this 50 is the down payment balance. Because of the arrears, there is still 50-6.34 left. This is also the available balance. The balance of the discount is allocated to you every month, and it will be used up in a few fixed months. The balance of prepaid interest is the remaining balance after settlement last month.
