On the day of 1 in the 23rd century, a man named Grandpa Hua was counting the stars. Suddenly a round thing fell from the sky and landed in a park. Master Hua saw it and drove the spaceship to the park. He picked up the strange thing and looked at it with the recognizer. It says "System failure". He thought it was strange and took it home.

The next day, Master Hua called the whole family together to study this strange thing. Daughter, the orange said, "Dad, this should be an ostrich egg!" " "Son, the orange said," Dad, that can't be a bomb! "Mrs. Hua was about to pick up this unknown thing when it cracked. Everyone couldn't wait to know what was inside, but they were afraid it was a bomb, so they hid far away.

The shell of the unknown object was completely broken, and something similar to a dinosaur climbed out of it. Master Hua handed him some ham, but the little thing didn't even touch it. It slowly climbed onto the balcony to eat leaves, and everyone was relieved. Because everyone knows that this little thing doesn't eat meat and won't bite itself.

It turned out to be a baby Tyrannosaurus Rex. Everyone thinks it's strange. Why did Tyrannosaurus Rex eat grass instead of meat?

In these doubtful days, the little Tyrannosaurus Rex grew up and became a dinosaur with a bigger house. Everyone thought there was no way to raise it, and it became as small as a puppy in a few minutes. But it is actually an adult dinosaur. Everyone thinks it is very good and ignores it.

At this moment, on another planet, the dinosaur headquarters has found that Master Hua and his family are raising small dinosaurs. In fact, dinosaurs didn't go extinct, they just went to another planet to survive. Besides, they have evolved. Now they don't eat meat, they are small, they can talk and work! Now, the big ones are as big as people, and the small ones are as big as sheepdogs.

Dinosaur headquarters wanted to know whether humans could live in harmony with dinosaurs, so they sent several dinosaurs to the earth.

Pterosaurs came to the earth and flew in the air. It met many spaceships. It will stop and go when it sees the traffic lights!

Since these dinosaurs came, everyone knows that Master Hua has a little dinosaur at home. Therefore, Master Hua's family was rated as "the first human family in the world to live in harmony with dinosaurs".

The harmony between humans and dinosaurs was known by the dinosaur headquarters, and they decided to live on the earth with humans.

Since then, many new occupations have appeared on the earth, such as: dinosaur nanny, dinosaur dancer, dinosaur cleaner, dinosaur … dinosaurs have also become artists, pianists, painters, mathematicians, educators and poets …
