If you apply for a card through mobile banking, the approval time is 1-2 weeks.
Through WeChat, the approval can be completed within 5 working days at the earliest (at present, only customers with CCB credit cards are supported to apply for new cards).
If the application is made through CCB outlets, the approval time is 20-25 working days. After his card is basically passed, it needs to be filed, printed and handed over to the post office. It will be sent by registered mail in about 3 working days (except for some special cards in Shenzhen and Dalian), and it will be received in about 10 days.
