In terms of credit limit, if the host has multiple CCB credit cards, they will indeed use the highest limit (Sanqin Tonglong Card and Traffic Safety Information Card are two different credit card types). For example, if card A has 30,000 yuan and card B has 50,000 yuan, if card A uses up 30,000 yuan, card B can only use 20,000 yuan. In other words, the maximum use of the two cards combined is 50,000, not 80,000, while the use of card A cannot exceed 30,000.

At the same time, we would also like to remind the poster that when the cards have been activated and used, you must remember to make separate repayments according to the card number.
