Dear Li Hua,

     Glad to hear from you last Monday. From your letter, I have learned something about Kunming. Great

changes have taken place in Kunming. I am expecting to pay a visit to Kunming one day in the future.

     Now I am eager to know something about your school life, especially what you do in your school. I will

be more than happy if you can meet my request.

     I am looking forward to your letter.

     With best wishes.

                                                                                                                                              Yours,

                                                                                                                                               Mike
