Dear Frank:
How happy we are to learn that you will take part in our China idiom contest. This is what you should know.
We will hold a competition in the school library at 8: 00 am on February 20th, 20 16/KLOC-0. The typos in some Chinese idioms can be recognized. In addition, you need to say these idioms by guessing your partner's gestures. I wish I could remind you that you'd better prepare an idiom story in case you might be invited to tell one. By the way, all our Chinese teachers will be invited to be judges.
I look forward to your excellent performance in the upcoming competition. Best wishes!
Yours,
Li pin
