1. Understand the reason: Contact the credit card issuer and ask why the credit card limit was reduced. This could be due to factors such as a drop in one's credit score, poor payment history, or changes in the issuer's policies.

2. Check your personal credit report: Check your personal credit report to understand your credit status and possible problems. If there is wrong or inaccurate information, contact the credit reporting agency promptly to have it corrected.

3. Improve your credit score: If your credit score is low, you can take steps to improve your credit score, such as paying bills on time, reducing debt, and establishing a good payment record.

4. Negotiate with the issuer: Contact the credit card issuer to find out whether the original limit can be restored or the limit can be increased. Explain the repayment ability and credit status and provide relevant evidence, which may help to re-evaluate the credit limit.

5. Find other credit cards: If the credit card limit cannot be restored, you can consider applying for other credit cards or debit cards to meet your consumption needs.

6. Save expenses: Re-plan your consumption plan based on the new credit limit, arrange expenditures reasonably, and avoid exceeding the credit limit.

Is the credit card limit exclusive?

Credit card limits are usually enjoyed independently by individuals, not by individuals. Each credit card holder has his or her own credit limit, which is determined by the credit card issuer based on the individual's credit score, income, and other factors. Different personal credit profiles and credit card products may result in different credit limits. Therefore, credit limits between credit card holders are usually independent and do not share or affect each other. Each cardholder has his or her own credit limit and associated repayment responsibilities.
