In terms of credit limit, if the landlord holds multiple CCB credit cards, then they do share a maximum credit limit (Sanqin Tonglong Card and Traffic Safety Information Card are two different credit card types). For example, 30,000 A cards, 50,000 B cards, 30,000 A cards and only 20,000 B cards can be used. In other words, the two cards add up to 50,000, not 80,000, and the A card does not exceed 30,000.

At the same time, remind the landlord that when all the cards have been opened for use, you should remember to repay them separately according to the card numbers.
