Excuse me, will you change me some money, please?
Of course.
I'd like to change these dollars into RIB. Would you please tell me the exchange rate between American dollar and RIB?
Sure. At present one dollar is equal to 6. 4392 yuan. How many dollars would you like to change?
500 dollars, please.
Please wait for a moment. . . Now here is your Chinese currency. See if it's right. It's 3, 220 yuan. Please keep this exchange memo. You may need it for converting when you leave China.
OK. Thank you for your help. That's very nice of you.
It's my pleasure.
