I am glad to receive your letter. I am writing to tell you something about my school. You're right, many changes have taken place in the school. There is a new teaching building by the roadside. On the other side, what used to be the playground is now our new library. There are many kinds of books, newspapers and magazines there. The playground is in front of the school now. We also planted many trees around the school. I hope you can visit it yourself.

Best wishes to you.
