CCB's credit card is not approved on weekends, because the credit card department of CCB is also closed on holidays stipulated by the state. It will take some time for your application data to be transmitted to the credit card center, and it will also take some time for the data to be entered into the audit system. If approved, it will take 1-2 days to make the card. So it takes about 15-3 working days to sort out the process. You can check the audit progress by logging in to official website of China Construction Bank.
