documents: #Person1#: Good morning. This is Shanghai Car Rental.
  #Person2#: Good morning, Miss. A friend of mine suggested I call you to hire a car.
  #Person1#: Oh, yes. A lot of people do this these days.
  #Person2#: Yes, we are just on holiday here for a few days and they said it would be a good idea to hire a car to get around the city.
  #Person1#: Well, it certainly is. What kind of car do you want to hire?
  #Person2#: What can you suggest?
  #Person1#: We have a variety of choice, such as Xiali, which is the cheapest, 200 yuan a day, Citroen, Jatta, Elysee, but Santana sedans are the big favorite these days.
  #Person2#: How much if I hire a Santana for three days?
  #Person1#: Oh, that will be 1,200 yuan.
  #Person2#: On, it sounds a bit too expensive. What about a Jetta?
  #Person1#: It will be 300 yuan a day.
  #Person2#: Then I'd better hire a Jetta tomorrow morning, would there be any problem?
  #Person1#: No problem at all. Now let me take down your name and telephone number.
