Dear Sir or Madam,
Thank you of your time to read my letter. As the coming of the 50th anniversary of our school, I'd like to
be a volunteer.
I'll try my best to serve for our distinguished guests with enthusiasm. I have good understanding of our
school. I am sure I'll not only offer good services to the guests, but I'll also act an excellent communicator of
our school's culture. What's more, I can say standard Chinese and English. I had no trouble working 8 hour a
day this coming weekend.
I will value the chance and do all I can if I am accept.
Li Hua
