What's the story of kangaroo and cage?

One day, the city zoo found that the kangaroo escaped from the cage, so it held a meeting to discuss and agreed that the height of the cage was too low. So they decided to raise the height of the cage from 10 meter to 20 meters. As a result, the next day they found that kangaroos were still running outside, so they decided to raise the height to 30 meters again.

I didn't expect to see all the kangaroos running outside the next day. The keeper was very nervous and decided to raise the height of the cage to 100 meters.

. One day a giraffe was chatting with some kangaroos. "Do you think these people will continue to keep your cage?" Asked the giraffe. "It's hard to say." Kangaroo said, "If they continue to forget to close the door!" " "

Moral: There are "beginning and end", "importance" and "urgency". Closing the door is the end point, lifting the cage is the end point, and it certainly doesn't matter to give up the end point.

Extended data:

Kangaroos and cages are from Aesop's Fables, which is said to be a collection of fables written by Aesop, an ancient Greek slave who was released in the 6th century BC. There are 357 stories about India, Arabia and Christianity.

There are more than 30 fables in Aesop's Fables, most of which are related to animals. The stories told in the book are short and pithy, and the images portrayed are vivid and vivid. Every story contains philosophy, or exposes and criticizes social contradictions, or expresses understanding of life, or summarizes daily life experience.

This collection of fables shows the social relations at that time by describing the relations between animals, mainly the unequal relations between the oppressor and the oppressed. Fable writers condemned the oppression of people by society at that time and called on the bullied people to unite to fight against the wicked.

Aesop's Fables had a great influence on the creation of later European fables. It is not only a model of western fable literature, but also one of the most widely circulated classic works in the world.
