Dear Mr John,
How are things going with you in Beijing?I am writing to show my thanks to you.
You tutored me in my spoken english before you went to Beijing.
With your help I made such rapid progress that i won the first place in the spoken english competition of the city.
My achievement is owed to your help. Thank you very much.
I have heard that you and your wife will pay a visit to my school. I am very glad at the news.
In that case we can see each other again.
I am looking forward to your coming. I am sending you a telescope as a small gift. I hope you will like it.
All the best. Yours, Liu Jie
