When using a credit card with a limit of 1 million, the following points can help you reduce debt pressure:

1. Carefully consider every purchase: When using a credit card, carefully consider every purchase. Whether the consumption is really necessary and avoid over-consumption. Only use your credit card to purchase items and services that you can pay off in a timely manner.

2. Develop a budget and repayment plan: Develop a detailed budget listing monthly expenses and income to ensure that you maintain good daily living expenses while paying off your credit card bills. Set up a repayment plan, make your payments on time and avoid late payments, which can incur high interest rates and additional penalties.

3. Try to repay in full every month: To avoid high interest and overdue fees, try to repay in full every month. This way, you can take advantage of the interest-free period offered by your credit card without racking up huge debt.

4. Pay attention to interest rates and fees: Carefully study the interest rate and fee structure of credit cards and choose a credit card that suits you. Make sure you understand transparent fees and only choose credit cards with longer terms or no annual fees.

5. Use installment payments with caution: If you do need to pay in installments, make sure you understand the interest rates and fees for installment payments, and choose an option with a lower long-term interest rate. Avoid excessive installments to avoid increasing your debt burden.

6. Properly manage your credit limit: Use your credit limit rationally and do not exceed what you can afford. Make sure you keep a portion of your credit line aside for emergencies to avoid being unable to use your credit card in an emergency.
