Good morning， sir.
Good morning. My wife and I would like to do some sightseeing today. Would you please introduce some places of historical interest in Beijing?
My pleasure， sir. Above all， I would recommend the Great Wall. It is amazing.
I’ve heard of it for a long time.
Yes. As the saying goes， ‘He who has never been to the Great Wall is not a true man’.
Great! Mary， let’s start off right now.
