Dear Mr. Chao and Mrs.Chao,
I'm the kid you helped. Thanks to your close attention paid on me, I've already recovered. I was born in a village and my family is very poor. There's no hope of recovery if I haven't got your donation. It was due to your help that I finally got well. I determine to study hard and will thank you again in the future.
Best wishes,
DAI dongdong
