Sharing, as long as the landlord holds multiple CCB credit cards at the same time, then they share a maximum amount, such as 30 thousand A cards, 50 thousand B cards, and only 20 thousand B cards are left after 30 thousand A cards are used up. In other words, the maximum amount of two cards is 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.
If the landlord has other questions, you can ask.
