There are no animals on the earth. This is a lifeless world.

You don't know which came first, the bird or the egg. I don't know, only birds know.

Whether the bird disappears first or the egg disappears first, you know, I know, only the bird doesn't know.

Animals are close friends of human beings, and human beings are trustworthy partners of animals.

Don't let our children only see today's animals in the museum.
