Don't take cash, because when you take cash, the interest is calculated from the time you take the money out. Brush credit, brush as little as possible, and then repay in full. You can improve your credit. Security cards are as easy to use as ordinary cards.

I don't know much about the bank's credit, but as far as we know, even if it is odd (it is said that each order is more than 5 yuan, you can swipe 10 if you are not at ease. Brush 20 bills every month and pay them back in full when they arrive. ), full repayment during the account period. No staging, no extension.

Besides, it's no use taking it out and putting it in. When you withdraw money, the money is used to calculate the bill for next month, and then used to calculate the bill for this period. If you deposit it and take it out, you will find that your interest will be much higher by the next billing date.

Credit card withdrawal is not recommended. Unless this is the case, you should swipe your card at a familiar store. Pay him a certain handling fee and get the rest at a discount. But don't stay in the same house all the time. It will affect the credit of the card, not the health card.
