The credit card of CCB is not activated, and the credit limit is insufficient 100. The reason for this is the following：

1. Deduct the annual fee: CCB credit card may automatically deduct the annual fee before you activate it. You can check the related bills of credit cards or contact China Construction Bank for details of annual fee deduction.

2. Temporary credit line: Some banks will grant temporary credit lines when issuing cards, which will take effect after activation. If your credit card has not been activated, it may show a temporary credit limit instead of your actual credit limit.
