Dear friends,

     I'm awfully sorry to hear that horrible and severe earthquake unexpectedly hit your hometown.

Faced with such a rarelyseen disaster, you remain as calm and strongwilled that we are all moved

to tear. A friend in need is a friend indeed. Think about your present situation, you can not wait a

minute to make every bit of our effort to help you. I, as for chairman of the Students' Union, on

behalf of all my schoolmates, express our most sincerely pity and care for you. Besides, we made

a donation of 120,000 yuan to you, expecting that it can help you go through the difficult. A better

hometown can be rebuilt. Remember we won't  be far away as you need any help!

                                                                                      Yours sincerely,

                                                                                              Li Hua
