中国成语故事传说：自胜为强

Zeng Zi saw Zi Xia and asked him, "Why have you gained weight?"

Zi Xia said, "I had a victory, that is why I have gained weight."

"What victory do you refer to?" Zi Xia said, "When I immerged myself in reading books, I revered(崇敬) the principles of the emperors and sages of the past. When I went out, I admired the life of nabodism. There was a fight between the two in my mind, and they came out even. So I got emaciated(瘦弱的). Now that the principles of the emperors and sages of the past have won victory, my mind has become more and more peaceful. So I have gained weight."

曾子见到子夏，问道：“你怎么胖了?”

子夏说：“我获得了胜利，所以胖了。”

曾子问：“你是指什么?”子夏说：“我埋头读书时，敬仰先生至圣的道理，出门在外则羡慕富贵生活的快乐，两者在心中交战，难分胜负，所以瘦了下来。现在，先王至圣的道理获胜了，心中也日益安宁，所以人也胖了起来。”
