This situation can be solved by trying to contact the bank customer service, applying for a temporary line and using other payment methods.

1. Contact the customer service of the bank: call the customer service of the credit card to apply for increasing the payment limit.

2. Apply for a temporary line: If you often need to spend more than 50,000 yuan, try to apply for a temporary line, but you need a good credit record and a high income level.

3. Use other payment methods: the credit card limit cannot meet the consumer demand, so you can consider using other payment methods, such as Alipay and WeChat payment.
