Dear uncle Wang,
I am from a poor mountain village.I am Li Hua. My family is poor, so my parents can't afford my school fee.As a result I dropped out of school last year.
Thanks to your help,I am able to go back to school. Thank you very much.I will study hard at school and get top grades, so I will go to college.I am sure in the future I can repay your kindness and the society.
All the best wishes to you.
