Stealing the light is an idiom in China, which comes from the story that Kuang Heng, a great writer in the Western Han Dynasty, dug a hole to attract his neighbors to study by candlelight when he was young, and eventually became a generation of writers. Now it is used to describe people who are poor and study hard.
Kuang Heng studied diligently without a candle. His neighbor had a candle but couldn't catch it, so he went through the wall to absorb its light and read it with a book that reflected its light. City people can't read their surnames. They have money at home and many books. Therefore, Heng is cooperating with him, not claiming compensation. The master was surprised and asked Heng, who said, "May the master read all the books." The host sighed, gave books and became a university.
Kuang Heng is diligent and studious, but there are no candles at home. There are candles next door, but the light can't reach his house. Therefore, Kuang Heng dug a hole in the wall to attract the light from his neighbors, so that it could be read in a book. There is a large family in the county, which is not very literate, but it is rich and has many books. Kuang Heng went to his house as an employee, but he didn't want to be paid. The host was surprised and asked him why. He said, "I hope to read all the books of the host family." Hearing this, the master sighed deeply, so he lent Kuang Heng a book (to help Kuang Heng read it). So Kuang Heng became a great scholar.
