There was once a little boy in the Ching dynasty whose name was Che-kwang. He liked to read very much, but his family was so poor that he could not even afford to buy candles.
"If Che-kwang's family is too poor to buy candles, how can he study at night and become so learned?" The little girl next door wondered. One day she decides to find out.
As the girl hid behind a tree in the evening, she saw Che-kwang coming home with a bag full of a glittering substance.
The girl was more curious than ever, and followed him into his house. She seized the bag and said, "What have you there?"
Before Che-kwang could stop her, she pulled the bag open and hundreds of fireflies escaped, lighting up the whole room.
