1. If you overdraw in foreign currency, you can choose to repay in US dollars or RMB regardless of whether the repayment date is at home or abroad. The difference is that if you repay in US dollars, you can still pay 100, assuming that you spent 100. If repayment is made in RMB, the repayment amount is the exchange rate of RMB against USD on the day of consumption. Assuming that the exchange rate on the day of consumption is RMB: USD = 1: 8, it is necessary to repay 800 yuan RMB. Suppose the daily exchange rate of consumption is RMB: USD = 1: 7.5, and you need to convert RMB into 750 yuan.
