Credit cards are really convenient to use. But if you don't use your credit card properly, it's really deadly. Credit card repayments will be compounded with interest. For example, if you owe 1 yuan a month ago, if you don't pay attention to it, the bank will not pay interest according to your unpaid debts. For example, if you repay 999 yuan and still owe 1 yuan, the bank will not pay interest according to 1 yuan, but will pay interest according to 1 yuan, that is, if you owe a month. You need to pay back 1 * .5 * 3 = 15 yuan

You are used to using credit cards, and you will get into the habit of spending in advance. That's a terrible thing. You have been using the money for the next month this month. What should you do if it breaks in the middle? And do you think it's comfortable to always borrow money to live and always owe money to others?
