English Original
An old crab said to her son, "Why do you walk sideways like that, my son? You ought to walk straight."
The young crab replied, "Show me how, dear mother, and I'll follow your example."
The old crab tried, but tried in vain, and then saw how foolish she had been to find fault with her child.
Example is better than precept.

小螃蟹回答说:“亲爱的妈妈,请示范给我看,我会照着您的样子做。”
老螃蟹试了试,但徒劳无功,这才意识到自己指责孩子是多么愚蠢。
身教胜于言传。
