Dear Mr. and Mrs. White,

I’m writing to you from my home in China. I returned back home safe and sound. When I think of the wonderfully two weeks I spend in Australia, I just can’t help thinking of you. You has provided everything to make my staying here such a happy and lucky experience. I’ve learned so many, not only English and also culture. Thank you very much. I’ll always remember the fun and laughter we shared each other as well as your kind. I’ll get in touch with you and write to you often. Please take care!

Yours,

Li Ming
