The withdrawal limit of CCB credit card is generally 50% of the cardholder's credit limit and cannot exceed the current available credit limit of the credit card. For example, if the credit line of the cardholder's credit card is 10000 yuan, then the cardholder's cash withdrawal line is 5000 yuan. It should be noted that China Construction Bank does not enjoy interest-free repayment when withdrawing cash from its credit card, and the bank will charge interest at a daily interest rate of 0.5 ‰, and calculate compound interest on a daily and monthly basis until it is paid off.
