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（鞭打）. 

Shortly afterwards, a fox came up to him and said, "Ah, I knew it was you by your voice."
