The "current balance" of CCB's credit card refers to the debt amount recorded in the credit card. The larger the amount, the more liabilities, the smaller the amount, and the less debt records. If it is negative, it means that there is still a balance in the card after deducting the debts that have been recorded, that is, the landlord has more money, and the landlord is 0, which means that it has not been recorded (while the beneficiary credit card has automatic installment function, and if the card has been used, there should be no debt).

"Available credit limit" refers to the maximum credit limit that can be used after deducting the used credit limit from the credit card. Is negative, indicating that the credit line used by the landlord has exceeded the credit line given to you by CCB, indicating that there is no available credit line. So the landlord can use 3000, which means you can use 3000 at most.

If the landlord has other questions, you can ask.
