If your original intention is that you don't have enough money now, use a credit card to make up for it first. Then I suggest you cancel this card immediately. Because the interest on credit cards is much higher than the ordinary interest rate of banks. It will only lead you into a vicious circle, as your boss said, cheat people. Haven't you heard that someone borrowed 5,000 yuan with a credit card and will have to pay back more than 20,000 yuan two years later?
If your original intention is that you have tens of thousands or even hundreds of thousands of deposits on you, and the purpose of using a credit card now is to facilitate consumption and you don't have to run the bank all day, then you can apply for a credit card and repay it online later.
But remember, don't deceive yourself, or you will die miserably.
