● This story comes from The Mencius, "Mencius debates the king of Liang." Later people used the expression "fifty paces laughs at one hundred" to describe people who have failed in a small way teasing those who have lost on a larger scale. Another usage is to describe people with the same trait or problem, with their difference only being one of degree.
這故事出於「孟子梁惠王篇」後人把「五十步笑百步」這句成語比喻那些以小敗嘲笑大敗的人；又以「五十步笑百步」來比喻程度不同，但本質相同的做法。
