English Translation:
A tiger caught a fox. The fox said: "You dare not eat me. The Heavenly Emperor has sent me to be the king of all beasts. Follow behind me and see if the animals are afraid of me." The tiger followed the fox, and all the animals ran away in fear. Actually, the animals were afraid of the tiger, not the fox.
