hello, after the credit card generates the USD bill, you can choose RMB to purchase foreign exchange for repayment or USD cash and cash for repayment;

1. Repayment by purchasing foreign exchange in RMB: ① Only one card RMB and credit card automatic repayment function are required, and RMB can be repaid directly without setting automatic repayment in USD; ② It is necessary to open the credit card to purchase foreign exchange for repayment;

2. Repayment in USD cash: ① Set the automatic repayment function of credit card, which defaults to USD cash and cash current account, or directly repay USD; ② It is necessary to cancel the repayment function of purchasing foreign exchange by credit card.
