A tiger caught a fox in a forest.
the fox said, 'You mustn't eat me. I was sent by Heaven to rule the animals. By eating me, you will violate the command of Heaven. If you don't believe me, just follow me to see whether the animals are afraid of me.'
The tiger agreed, and followed the fox as it walked around the forest.Sure enough, the animals all ran away on seeing them. The tiger felt very surprised thought they were afraid of the fox, so he let it go.
