Bank of communications credit card quota sharing. If you have more than one Bank of Communications credit card, whether it is a gold card, a regular card or a platinum card, you can use a higher credit card.

For example, if you have three credit cards with credit lines of 20,000, 30,000 and 40,000 respectively, then your three cards share a credit line of 40,000, and the credit line you can use is not 20,000+30,000+40,000 = 90,000.
