Extended information:

The word "borrowing light" has a long history. Kuang Heng was diligent and studious, but there were no candles at home. There was a candle in the neighbor's house, but the light couldn't shine into his house, so Kuang Heng cut a hole in the wall to attract the light from the neighbor's house, so that the light could shine on the books for reading. There was a wealthy family in the county who was illiterate and had many books. Kuang Heng went to his house to work as a hired worker, but he didn't want any reward.

The master felt very strange and asked him why. He said: "I hope to read all the master's books." The master was deeply impressed after hearing this, and used books to support Kuang Heng. So Kuang Heng became a great scholar of his generation.
