If you already have a credit card from Zhang Pingan Bank, then you apply for a credit card from Zhang Pingan, and the amount of the two cards is shared; If your previous credit card is not safe, it doesn't matter. Two credit cards are used separately.

If the credit card limit you originally applied for in Ping An Bank was 10000 yuan, and then you applied for one of them, the maximum overdraft limit of your credit card in Ping An Bank was 20,000 yuan. However, your original card can only be swiped out of 10000 yuan, and your later card can only be swiped out of 10000 yuan after it is full, which is equivalent to an increase in the quota.
