How are you these days? I am very thankful for your help when I visited London. London is really a very beautiful city and I enjoyed it very much. I had fun during that time and the friendly people impressed me deeply. What’s more, I am interested in London’s history. By the way, could you come to China for a visit? China is country which develops very fast, if you can, I will show you around to know more about Chinese history.
I am looking forward to your letter.
