You mean that you have applied for a new credit card from China Construction Bank, but there is no available credit line?

If so, how many credit cards do you have at CCB? You should remember that the credit card limit under your name is shared, not accumulated. For example, you already have a bank with a credit line of 10000 yuan, and now you have spent 10000 yuan, so the available credit line is 0. If you set up another B card of CCB, the amount will also be 10000. Although I just applied, it is useless, but the available amount is also 0, because using another card will also affect this card.
