Dear Xiaowang,
     How are you these days?
     The holiday is coming. It's really a nice holiday, isn't it? I still remember that you once invited me to travel with you. Maybe we'll have enough time soon. I'd like to visit some places of
great interest and eat delicious food. It must be exciting to travel with you.
     Ha! Ha!
     You are a good traveler and could you tell me when and where to go, how to get there
and what to do there?
      Please e-mail me soon. Good luck with you!
                                                                                                                     Yours,
                                                                                                                  Xiaoxing
