Dear Tom,
I am delighted that you have passed the exam successful. What you have gained are the result of your hard work. How time flies! It’s two years before you came to study Chinese in Beijing. In the passed two years, you have helped us a lot, without that we couldn’t have made great progress in English.
Before you leave, many classmate and I intend to hold a farewell party for you, hope that you can remember the wonderful time we spent together. By the way, the party will be held on this Saturday evening in my house. We can take the No.1 bus at the hotel gate and get off bus at the Booking Building. I will be there meeting you.
We’re looking forward to your coming.
Yours sincerely,
Li Hua
