dear tom,
i'm glad to know you will come to china. in winter, the sky is azure here. i believed you will meet the amazing vista in china. probably because of the nino phenomenon, it's not so cold as years before.
you had better visit tian'an men square. it's exceptionally great! your country has the yellow stone park whereas mine has the great walls as wonderful as yours. therefore i suggest you to have a look.
don't miss the spring festival! you can do alot of things interesting during it. nevertheless, do not eat too much, otherwise you can't enjoy the beijing duck! it's sure that the beijing duck will beyond your imagination. thus keep your expection.
have a good time! i think you'll always cherish the memory of this trip when you come back home.
yours,
li lei
