Dear Jim:

     I am very glad to hear that you are coming to China in Winter Holidays. In your letter you ask me

 which the best way to travel in China is.

     In my opinion, I think it's better for you to travel by train than by air in China.

     First of all, train is the safest means of transportation. we can use our mobile-phone and laptop at any

 time on the train. Another thing I like about train travel because I can get up and walk around. There is

 often a cafe or dining car so I can go there and have a cup of coffee. What's more, if you want to save

 more money, taking trains is more cheaper than taking planes. Finally, I also enjoy looking at the scenery

 through the windows of trains.

                                                                                                                                Yours，

                                                                                                                                Wang Hai
