Hello, if the "payable amount in this period" of your credit card RMB or USD account is negative, it means that there is still deposit in the RMB or USD account, and there is no need to make another deposit. This bill is for reference only. 2. If there are refunds and rebates from merchants, they will be listed as negative values and displayed in the "Current Adjustment Amount" of the bill. 3. If the customer returns US dollars in RMB, we will list the exchange rate of automatic foreign exchange purchase in the transaction summary of your US dollar bill, so that you can know the amount and exchange rate of foreign exchange purchase.
