The interest-free repayment period of Guangfa Bank's credit card for several days is really an indispensable advantage. With a money fund that pays interest on a daily basis, this cheapness can be directly converted into money.

In the same bank, you can apply for a savings card and an overdraft credit card, and then leave a small amount of emergency cash for your monthly salary, all of which will be deposited in the savings card and bought into a money fund. Then, all your daily needs are overdrawn by your credit card. (At present, almost all small supermarkets and shopping malls can spend money by credit card, and some preferential activities are often launched for different card-issuing banks. After receiving the credit card bill every month, you can redeem the corresponding amount of funds two days before the due repayment date. It sounds very troublesome, but if you use the salary card as a savings card and handle banking services such as "automatic repayment" (free of charge), you can greatly save the above procedures.
