She lives in a poor village called Zhangjiashu in Tongxin, Ningxia, and she has no money to go to school. However, she is brave and wants to go to school very much.

Ma Yan is now a Junior Three student at Yuwang Middle School in Tongxin. Before this, she had to drop out of school twice. She had to stop going to school the first time, because her mum told her there was no money for her to go to school. She worked for 21 days and saved 13 yuan. With this money, she went back to school. The second time, her family told her she had to leave school while her two brothers could stay. "I want to study," Ma Yan wrote in her diary.
