Dear Li Ping,
I heard that your school was going to have an English Festival next week. I'd like to come and join you, but could you please tell me more information about it? When is it exactly? What interesting activities are there? You know I like making friends, so is it possible for me to sing an English song and let others get to know me?
Hope to hear from you soon.
Yours,
Mike
