Long long ago, there is a child.His name is Che Yin.He is smart and loves to read.His parents don't have much money.They can't buy lamp oil (灯油) for Che Yin to study at night.
One night, he sees fireflies (萤火虫) outside his house.Then he thinks, "Can fireflies be my lamp?" He gets some fireflies in a bag and uses the bag to be a lamp.It's great.He reads like this at night.
Another child, Sun Kang, also loves reading.One night, Sun Kang doesn't have lamp oil and can't study.When he gets up at night, he sees the snow reflecting the moonlight(反射月光) outside his house."I can use the reflected light to read," he thinks.He takes out his books and reads.He is very cold, but he still reads outside.
The two children become great people.This is the story of Nang YingYing Xue.
