Usually deducted once on the same day. If it is a commercial loan, the automatic deduction method for personal loans is twice a day. The system will automatically deduct the loan account before the business starts on the morning of the repayment date, and automatically deduct it for the second time after the business ends that day. Under normal circumstances, the fee will be automatically deducted every night 18. It is recommended that you deposit enough funds in advance to avoid overdue.
