Supported! Select the credit card tab in the online banking payment channel to pay by credit card.

I guess what you mean by "not supported" may mean that the installment instructions do not mention CCB. If that's the case then you've misunderstood. There are three main types of credit card installment operations:

One is that the bank and the merchant have an agreement. When making a purchase, the merchant can directly perform the installment operation for the consumption. In this case, the payment will be made directly after the card is swiped. The installment was successfully processed.

The other is that after the consumption operation is completed, the cardholder contacts the bank to apply for installment of the consumption. This kind of installment requires the bank's approval and may not be successful.

The third type, of course, is that some credit cards represented by China Guangfa Card support automatic installment. After the cardholder signs a contract in advance, the system will automatically make installments for consumption that meets the conditions.

After this explanation, it is not difficult to find that the installments of China Merchants Bank, Bank of China, etc. listed in the installment introductions of JD.com and Newegg actually belong to the first type. That is because they have an agreement with the bank and can Perform installment operations on behalf of consumers. After you use your CCB credit card to make purchases, you can still use the "second" method to apply for installments, but you may encounter disapproval.
