The credit card of CCB can be used for 8,000 yuan, and the maximum cash limit is 4,000 yuan. It is impossible to take it out completely. Withdraw 4,000 yuan to get 20 yuan service fee, and there is no interest-free period for withdrawal. 4,000 yuan daily interest 2 yuan, until the service fee is paid off. As long as you still have one point unpaid, you will also calculate the interest according to the daily 2 yuan. Be careful, so it is not recommended to withdraw cash from the credit card.

If you spend 8,000 yuan with a credit card and there is an interest-free period, there is no interest in paying off the amount within 20 days after your bill comes out. For example, if your bill date is 17, you spend 8,000 yuan by credit card on July 9, and your bill rises on July 17, then you can pay it off 20 days later, that is, before August 7, without charging you interest.
