Dear Mary,

     It is known to everyone: Oct. lst is our National Day. It is coming. I am having a seven-day holiday.

I like  traveling  for vacations. This time I am going to Lhasa, the capital of Tibet, because  there  are  

beautiful  views everywhere-bright sunshine, blue sky and clear air. I am going with my parents. Of

course, we are taking the train to get there. The new railway between Tibet and Qinghai has been built

already.  I am visiting many places of interest in Lhasa. I am going hiking and camping there, too. I am

staying . there for about a week. I think I am 'having a good time there. Would you like to go there with

me? I hope you can.

                                                                                                                                           Yours,

                                                                                                                                            Jack
