As a Perking University graduate and volunteer,Yang Lei is now teaching high school students in a poor mountain village in Gansu Province.
It is not easy for her to live though the early days.As the village was 2,000 meters above sea level,the thin air makes her feel sick.And the food is only porridge.However,both she and her husband think it's a good idea to stay there.Most of the pupils live in the dormitories and study very hard.They love volunteer teachers there because they're just like elder sisters to them.
Lacking of money,some of the students may not able to go to senior high school or college.Yang lei says that she can't change the poverty but she will do everything she can to change the children's lives.
