In ancient times there were no donkeys inGuizhouProvince. Somebody brought a donkey from somewhere and tied it to a tree at the foot of a mountain. A tiger saw the donkey, and thought that it must be a fearsome monster. It hid behind a tree and spied on the donkey. When the donkey brayed, the tiger was frightened, thinking that the donkey was about to devour it. After a while, seeing that the donkey had not moved, the tiger approached it and teased it. The donkey became angry, and kicked the tiger. The tiger thought to itself: ‘Is that all it is capable of?’ It then jumped on the donkey and ate it.
