Why did Kuang Heng cut the wall for light?

Kuang Heng wanted to study when he was a child, but because his family was poor, he couldn't afford to go to school. Later, he learned to read from a relative before he could read. Kuang Heng can't afford books, so he has to borrow books to read. At that time, books were so valuable that people who had books refused to lend them to others easily. During the busy farming season, Kuang Heng worked as a short-term worker for wealthy families and asked them to lend him books for free.

A few years later, Kuang Heng grew up and became the main labor force in the family. He works in the fields all day, and only has time to read some books during his lunch break, so it often takes ten days and a half months to finish reading a book. Kuang Heng was in a hurry, thinking: planting crops during the day, no time to read, you can spend more time reading at night. But Kuang Heng's family is too poor to buy oil for lighting. What should we do?

One night, Kuang Heng was lying in bed reciting the books he had read during the day. Behind me, I suddenly saw a light coming through the east wall. He stood up and went to the wall to have a look. Ah! It turned out that the neighbor's light came through the cracks in the wall. So Kuang Heng thought of a way: he picked up a knife and dug several cracks in the wall. In this way, the light coming through is also very big, so he gathered the light coming through and began to read.

Kuang Heng studied hard and thrived in this way, and later became a very learned man. This story is also called "Digging a wall to steal light" and "Digging a wall to borrow light".

Extended data:

The Kuang family has been farming for generations, but they are very diligent and eager to learn. Because his family is poor, he has to help others get an education. His story of "digging the wall to borrow light" is widely praised by the world.

The Kuang family has been farming for generations, but they are very diligent and eager to learn. Because his family is poor, he has to help others get an education. He was studying the Book of Songs with a doctor. Because of his diligent study, his understanding of this poem is very unique and thorough. Confucian scholars at that time once said that there was no need to say poetry. Kuang said "The Book of Songs", which means that listening to and explaining "The Book of Songs" can make people frown and feel comfortable, showing a profound understanding of the Book of Songs.

But Kuang Heng's career didn't go well at first. According to the regulations of the Han Dynasty, once a doctoral disciple has mastered one of the Six Classics, he can obtain an official position through the examination. A-level students can be doctors, B-level students are Prince Scheeren, and C-level students can only make up literary anecdotes. Kuang Heng got nine subjects, only a C, and was compiled as a history of literary death in Taiyuan County. However, Kuang Heng's profound understanding of The Book of Songs was highly valued by the literati at that time, and Yuan Di, as a prince at that time, also had a special liking for The Book of Songs.
