documents: #Person1#: David, recently I established a travelling forum, and now I want to make a plan to hold the first activity. Where can we go for this time?
  #Person2#: How many members are there in your forum?
  #Person1#: a dozen.
  #Person2#: I think we can visit West Lake. The landscapes are attractive. It is said that just as there is paradise in heaven, there are Su Zhou and Hang Zhou on earth.
  #Person1#: It's surely worth going to. There are ten famous spots there.
  #Person2#: Great, let's say Hang Zhou is the place. What can we do next after locating the place?
  #Person1#: Inform my members to prepare for the travelling to Hang Zhou. And then we can discuss about the travelling costs.
