If it is a CMB credit card, you can reapply after the temporary quota expires. In addition, after the temporary line expires, the used temporary line (exceeding the fixed line) will not enjoy the convenience of revolving credit, and will be included in the minimum repayment amount of the latest bill, and must be paid off in one lump sum on the due repayment date. If you can't pay off, you can check whether you can apply for bill installment through customer service evaluation.
