The initial credit card (debit card) limit of China Construction Bank is 5,000 yuan, and CCB can automatically increase the credit card limit through good repayment records and consumption records. Or, after users use it for a period of time, they take the initiative to apply for an increase in the quota. CCB will evaluate users' usage, and consider that users meet the conditions for increasing the quota, and will increase the quota for users. If you don't actively apply for increasing the quota, you have to wait for the system to automatically increase the quota.

Therefore, users applying for active quota promotion can effectively shorten the time for quota promotion, but the active quota promotion may not be successful.
