if you mean to directly issue a dollar bill after spending dollars, don't turn on the function of "automatically posting RMB after spending dollars". When foreign currency consumption has generated a dollar bill, you can choose to turn on the function of "purchasing foreign exchange for repayment with dollar bill". After opening, your RMB repayment will be automatically converted into US dollars, and your US dollar bill will be repaid first (the exchange rate is the exchange rate on the day of your payment), and the repayment after the US dollar bill is paid off will continue to repay your RMB bill.
