Bank of China has a large credit card limit, but usually it needs to be increased after long-term consumption and good repayment record. If you want to apply for a large credit card directly, you can try to provide more financial proof and apply for a platinum credit card. The financial proof recognized by the bank includes: payroll records issued by the bank, or income tax withholding certificates, or documents proving the market value of houses, automobiles, deposits, investments, etc. (such as a copy of real estate license/automobile driving license/bank time deposit certificate); The more personal assets, the more financial certificates provided and the stronger repayment ability, the easier it will be to apply for a large credit card.
