Dear Mr. Smith,
I'm writing to invite you to the Traditional Chinese Cultural Fair be held by our school at the Art Center this Friday afternoon, at 2p.m .to 5p.m.
Since a event aims to help more people learn about the traditional Chinese culture, the staff, all the students and their parents as well as anyone interested in it is welcome. At the fair, relating books, pictures, videos and objects will be exhibited, through that visitors will not only understand traditional Chinese culture better but definitely feel about the unique beauty of it.
If you were interested, please come and enjoy them. And I'd be glad to offer any helps. Looking forward to your early reply.
Yours,
Li Hua
