I'm lihua, a boy who was your student when I was in senior grade one and two. I have learned that you're going back to your country, so please allow me to express my thanks to you for your help.
My English used to be poor and once, I wanted to give up. It was your patience end encouragement that made me in love with English, and now I am doing very well in it. I appreciate what you did for my English study. Without your efforts, I wouldn't have achieved so much.
Again,I'm truly grateful for your help,I heartily hope that you are happy and healthy everyday!
