You can log on to the credit card website of CCB, click "Credit Card Online Application" and fill in the information directly to apply. It is convenient to apply without providing any economic proof. But because you don't need to provide any information, the bank will generally review your personal payment and credit status. If you don't pay or pay less, it is not recommended to apply in this way because it is difficult to pass. In this case, you can provide more financial proof to apply at the outlets, such as providing some certificates of time deposits or passbooks for real estate, automobile production or China Construction Bank. The more information you provide, the more helpful it will be to your card review.
