This method is feasible, but the bank doesn't want us to do so, but we can realize mutual transfer between credit cards through Alipay. I don't know if the bank doesn't know about this loophole, or if they can't prevent it at all ... This method is very easy to use, but I just don't want the bank to plug this hole. In this way, using a credit card is the same as swiping it. You don't need to repay the overdraft before the latest repayment date, and you don't need to worry about any interest. Agree 2| Comment
