《古代寓言·羊蒙虎皮》
羊质而虎皮，见草而说，见豺而战。忘其皮之虎矣。
——《法言》
The Lamb in a Tigers Skin
Once a lamb clad itself in a tiger’s skin.
As it was stalking along, it bleated joyously at the sight of the green grass, but when it saw a wolf in the distance it trembled all over.
The truth is that the lamb had forgotten that it had the tiger’s skin on.
