     Almost every child in cities has the chance to go to school, but not all children in the countries are so

lucky. 

     There is a girl called Xiao Fang. She is eight years old and lives in a small village in Guangxi. When she

was young, she wanted to go to school. But she could not, because her family was too poor to afford the

school fees for her, so her parents had to keep her at home. Instead of studying, Xiao Fang worked in the

fields with her parents every day. Then Hope Project heard about Xiao Fang. It agreed to help Xiao Fang to

go to school. Her wish of study came true, and now she is studying in a school.

     Unluckily there are many thousands of children who can not go to school. You can join in Hope Project

and help these children. You know all the good work needs money. Hope Project needs your help.
