Kuang Heng was born in a poor family. He liked reading books very much. He needed to work at daytime, so he had to read books during night. But he was too poor to buy a candle.
One day, he found his neighbour had candles, but the light couldn’t go through his room. So he dug a small hole on the wall so that he could use the light to read books. From that day, he read books every night until the light went out.
However, he finished reading all his books and there were no books for him to read. Then he went to a rich man’s house and worked for him without payment. The rich man asked: “ Why don’t you want the money?” Kuang Heng said: “ Because I only want to borrow your books.” The rich man agreed. Kuang Heng read the books one by one. Finally, he became a great scholar.
