Dear Black,
I am writing to express my thanks for your kind help during my visit in England. Many thanks for all the things you have done for us. And thank you for the gift you sent me. It’s one of the best gifts I have ever got.
During my stay in your country, you offered us such good opportunities to communicate with you and your students. Therefore, I have learned more about English culture and my English has improved a lot. Besides, I have made several good friends there.
I am looking forward to your early visit to China so that I will show you around our country.
Thank you again for your kind help.
Best wishes.
Yours sincerely,
