Study hard and learn good allusions in the history of expansive materials: poaching and stealing light.
Kuang Heng, a great writer in the Western Han Dynasty, cut through the wall to attract his neighbors to read by candlelight when he was young, and eventually became a story of a generation of writers. Now it is used to describe people who are poor and study hard.
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 big family in the county, which is famous for its literary knowledge, 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.
It can be seen from the example of digging the wall to borrow light that external factors (environment and conditions) are not decisive factors, external factors are only conditions that affect the change of things, and it can only work through internal factors.
It's the same as sugar cane.
