Classic Poem

Where did this tiger come from?
He has invaded the village of Three Forks!
Yesterday he devoured the eastern neighbor's pig,
today he has eaten the western neighbor's dog!
The animals of the mountain dare not make a sound;
dark winds blow in the poplars and bamboo.
A youth from one family, feeling very brave,
goes off into the mountains, with his bow and arrow.
Late at night, beneath a black moon, he stalks the tiger...
and the next day, only his white bones are found,
in the wild grass.
