原文：

杨氏者，富人也。其家大富，田宅广袤，奴婢众多。然杨氏性吝啬，虽富有，却常自苦，不肯轻易施舍他人。一日，杨氏入山伐木，路遇一老翁。老翁问曰：“汝何为入山？”杨氏答曰：“伐木以售之，得利而归。”老翁笑曰：“汝虽富，然心贫矣。若能施予他人，方显真富。”

杨氏不以为然，仍继续伐木。数日后，杨氏因劳累过度病倒，家中无一人前来探望。杨氏悔悟，遂改变态度，开始乐于助人。自此，杨氏不仅精神愉悦，且生意兴隆，生活更加美满。

翻译：

There was a man named Yang who was very wealthy. His family owned vast fields and numerous slaves. However, Mr. Yang was stingy by nature, unwilling to give even small gifts to others despite his wealth. One day, while he was in the mountains cutting trees for sale, he met an old man. The old man asked him, "Why do you come to the mountain?" Mr. Yang replied, "To cut trees for selling, so that I can make money and return home." The old man laughed and said, "Even though you are rich, your heart is poor. Only when you give to others will you truly be wealthy."

Mr. Yang ignored the old man's words and continued chopping wood. A few days later, due to overwork, he fell ill, but no one came to visit him at home. Mr. Yang regretted deeply and changed his attitude, beginning to help others. From then on, not only did he feel happy mentally, but also his business prospered, making his life much better.
