An ass once found a lion's skin. He put it on, and walked towards the village.
All fled when he came near,both men and animals.
The ass felt quite proud. He lifted his voice and brayed, but then everyone knew him.
His owner came up and gave him a sound whipping.
Shortly afterwards,a fox came up to him and said, "Ah, I knew it was you by your voice."有头驴发现一张狮子皮，他披着狮子皮走进村庄。
驴感到很得意，他高声地嘶叫，却被人认了出来。他的主人跑过来打了他一顿。
不久，一只狐狸也跑过来，对他说：“哦，你一张嘴我就知道你是驴。”
寓意: 外表虽然可以暂时掩盖一个人的缺点，但它很容易被揭穿。
