The Axe at Lu Ban's Gate
班门弄斧
bān mén nòng fǔ
A Ming-dynasty official read the bad poems scrawled across Li Bai's grave and answered with the four words that became Chinese for showing off exactly where the real master can see you do it.
A theme across cultures
Hypocrisy is the gap between the face shown to the household and the face shown to the world. Proverbs catch it with affection more often than scorn — most cultures have noticed that humans cannot help being slightly different in front of their mothers than in front of their bosses.
The Mongolian gertee bar, gadaa khulgana — “a tiger at home, a mouse outside” — turns the observation upside down: the same person is one creature inside the door, another outside it. The image stays with you long after the proverb itself does.
