answer: #Person1# recommends Mei Hong to go to Xi'an by air and will book a ticket for Mei Hong.
documents: #Person1#: Hey Mei Hong, how are you getting to Xi'an next week?
  #Person2#: I'm not sure yet. I may take the train but then again I might take the bus.
  #Person1#: Yeah but the bus takes a long time. You could fly - it's not so expensive these days.
  #Person2#: Really? Maybe I'll do that then.
  #Person1#: Ok well, you let me know your schedule and I'll book a ticket for you.
  #Person2#: Ok. Thanks for that!
