Dear Tom,
How are you? Thank you for your letter. I am really excited about our new teaching building. I can't wait to share with you about it.

It is a five-storey building located on the east side of our campus. When I go up to the fifth floor, I can get a full view of our beautiful campus. Our classroom is so spacious and outfitted with state-of-the-art teaching equipment. Our classmates have put in an earnest effort to maintain cleanliness and upkeep of the classroom.
In short, it's great to see our new teaching building come to life before our eyes. I wonder if there is any chance that you could pay us a visit in person soon.
Yours truly,
