Your current comprehensive score has not reached the standard set by the CCB system, so your card application was rejected by the system. System audit will refer to many standards, including your work situation, income situation, personal financial situation and so on. As this is the result of comprehensive evaluation, I'm sorry I can't tell you the specific reasons. If you want to reapply for CCB credit card, I suggest that you try to supplement your financial information and reapply after three months.
