The repayment date of ICBC's car loan is 25th, and I successfully repaid it in Alipay on 23rd. Will there be a message from the bank? Will the bank not deduct money until the 25th?

The repayment date is 25th, that is, the deduction will be made on 25th. Generally, car loans are similar to mortgages. If you use a bank card to pay back the car loan, the bank will generally ask to open a text message or something. When the repayment date is approaching, the bank will generally scan whether the amount of your bank card can pay the car loan. If the amount is insufficient, the bank will send a short message to remind you that the amount is insufficient, and the date of deduction is the same.
