In order to restore your credit card limit, you can try to increase your actual consumption ratio, and try to choose credit card as the preferred payment method when spending in bars, hotels, supermarkets, restaurants and other places.

3. Reduce the debt ratio: specifically, stop large expenditures and reduce installment consumption. Large consumption means that the single amount of credit card exceeds 50% of the limit. If a large amount of consumption occurs many times, it is easy to trigger the risk control of the bank and make the bank suspect that the cardholder has illegally taken the current behavior. If you often pay by installments, it will also make banks doubt the repayment ability of cardholders, thus reducing the credit limit of credit cards.
