If your credit card monthly payment limit is 50,000, it can be lifted by increasing your credit limit, increasing your credit card limit, and applying to the bank to cancel it.

1. Increase your credit limit: You can apply to the bank to increase your credit limit. Banks usually evaluate your credit limit based on your credit history and income. If your credit record is good and your income is stable, the bank may approve your application.

2. Increase your credit card limit: If your credit card limit has reached 50,000, but you still cannot use more than this amount, you may consider applying to the bank to increase your credit card limit.

3. Apply to the bank to lift the limit: If the bank suspects that your account is subject to risk, you need to go to the bank to go through the limit lifting procedures.
