I suggest you try to handle it through the self-service channels of BOC (Bank of China Mobile Banking, "China Bank Credit Card" WeChat official account, BOC Colorful Life APP). Handling related businesses through self-service channels will also inquire about their credit information, and the increase results will be returned in 1-3 natural days, and the results will be subject to SMS. Or you can wait for the Bank of China to increase the amount of eligible cards from time to time, and generally make a comprehensive evaluation with reference to your frequency of use, repayment record and consumption type. I suggest you choose diversified consumption and keep a good repayment record, which will help to increase the quota.

The above contents are for your reference. Please refer to the actual business regulations.

If in doubt, please consult the online customer service of China Bank or download and use the mobile banking APP of China Bank to handle related business.
