No, withdrawing cash through formal channels is one of the functions of credit cards. There is no rule that the money obtained after withdrawal can only be done.

However, it should be noted that credit card withdrawal is interest-bearing, which is generally charged according to five ten thousandths of the cash withdrawal amount. For example, if you take 6,543.8+0,000 yuan, the daily interest will be 5 yuan, and the compound interest will be calculated. Secondly, the cash withdrawal part of the general bank credit card must be returned in full, and the cash withdrawal part cannot be paid in installments or exchanged for the minimum repayment amount. For example, if you take 10000 yuan and spend 5000 yuan with a credit card, the 10000 yuan withdrawn on the repayment date must be returned in full, and the 5000 yuan spent with a credit card can be returned in installments or exchanged for the minimum repayment amount.
