nts: I’m a middle school student in Beijing. Last summer holiday, I went to my grandparents’ in Gansu. There I met several friends. They were at the same age as me. But they dropped out of school because their families were poor. Li Yinming is only 14, but he has been away from for several years only because his parents have been ill and and he has to look after them. There are still more children like him. So I hope you will help them so that they can study at school. I think they will be thankful. Thank you! a middle school student 1.
