I’ve come back home safely. Looking back to my stay in Britain, I feel so happy and satisfied. The beautiful scenery and friendly people impressed me a lot. I also benefited a lot from learning together with local students (about the custom in your country). More importantly, your help and kindness made it easier for me to have a better understanding of British culture and adapt to the life there. / Thanks to your help and kindness, I can have a complete and clear comprehension of British culture.

You are expected to come to China soon.
