1. Mortgaged passbooks are the same as ordinary passbooks, and can be deposited and taken;

2. Just deposit the repayment amount of the current month into the passbook before the monthly deduction date. It is recommended to deposit more because the number of days in each month is different, and the repayment amount is calculated according to the actual number of days, resulting in a slight difference in the monthly repayment amount. Theoretically, the repayment of equal principal and interest is the same, and the average capital is decreasing;

3. When repaying the loan, there is usually a buffer period of the month. When the loan is repaid before the end of the month, it will not be submitted to PBOC, but will be recorded in the internal system of the lending bank.
