each bank has different policies. Some of them are deducted from the transaction at that time, while others can be counted as repayment. It is specifically suggested that the landlord can call the bank's customer service hotline to confirm.

Here, taking the CCB credit card I used as an example, the money refunded by their family is counted as repayment. You can first deduct the bill owed, and if there is more, you can deduct the unpaid bill owed, and the balance will be in the landlord's credit card account.
