Well, it means that you are tight now and lack emergency funds, and you have a credit card, but the credit card can only be used for consumption. If you withdraw cash, the limit is usually halved, and the handling fees and interest are very high. At that time, you need to find someone with a POS machine, go to his place and transfer the credit limit on his credit card to him. After deducting the agreed commission, he will give you the remaining cash. Commonly known as credit card cash out.
