Excuse me, could you tell me where the post office is?
Post office? It's not far from here. Do you know Xinhua Road?
I'm from the United States and this is my first trip to your city. I know nothing about the city.
Oh, welcome to our city, I'll show you the road. Please follow me.
Thanks, by the way, where can I buy a map of the city?
Just at the gate of the post office. Look, the post office is just across the street.
Thank you very much. Good-bye.
Good-bye.
