Dear Mr. and Mrs. Johnson,

    I’m writing to tell you that I had a safe journey back to Xi’an. Thank you so much for your kind reception, which assured that I had a wonderful time in London.

    Though I was a little nervous when I first arrived, your warm smiles and kind advice made me feel at home, with your help, I enjoyed the most exciting events in the Olympic Games and visited so many places of interest in London, which left me quite a good memory.

    I hope someday, you will come to China. I’ll show you around Qin Terracotta Warriors and Horses Museum and the Great Wild Goose Pagoda in Xi’an, as well as some other Chinese places of interest, such as the Bird’s Nest and the Great Wall around Beijing.

    Thanks again.

 Yours，
