How much pocket money do you get from your parents every month? Maybe 200 yuan? But for Li Beibei, 30 yuan each month is enough. The only thing she buys is lunch—1.5 yuan each day. “Meat is too expensive for me,” said Li.

Li, 14, is a Junior 1 student at Beijing’s Xingzhi Experimental School. Her parents are migrant workers(外来务工人员). They came to Beijing from a village in Luohe, He’nan two years ago. Her father now works as a cleaner and gets 500 yuan every month. Her mother has no job.

Li Beibei has 460 friends at Xingzhi. Every day, Li gets up at 5:30 am and rides her bike for 20 minutes to get to school. Like many teens, Li has a lot of homework—usually at least one hour every day. But that is not all her work. During the weekdays she helps her mum cook. On weekends, she helps wash clothes. “I could cook when I was eight. Dad said sometimes I cook better than Mum!”

Li said she wanted to be a doctor. “I watch TV and find out there are many people with AIDS in He’nan. Some are kids. They need help,” said Li.

But she is afraid to leave school. “I hope I will always be in school,” said Li. “Dad works hard to get money. I promise him I will study hard to be a good student and a good doctor in the future.”
