A story suitable for seven-year-old children

The story suitable for seven-year-olds is as follows:

Long ago, animals lived happily on the ground. Because the rooster sang beautifully, the fairy in the sky was moved and gave him a diagonal line. As long as he wears this diagonal line, the rooster can fly freely into the sky. The rooster told all the interesting things he saw in the sky to his friends on the ground, and everyone was curious about life in the sky.

One day, the rooster's good friend Long came to him and said, "Brother Rooster, can you lend me your horn?" I also want to see the sky. I promise to return it to you as soon as I finish reading it. The rooster thought for a moment and said, OK. He repeatedly told the dragon to return the horn to himself immediately after reading it. The dragon agreed.

Put on the cock's horn and the dragon flew into the sky at once. He can't get enough of everything in the sky. I forgot to promise the rooster a long time ago. The rooster on the ground looked up in a hurry and shouted, Brother Long, come back and honk your horn. But the dragon ignored him and stayed in the sky. The rooster can only keep shouting: Brother Long, come back and honk the horn. Brother Long, come and return the horn.

As the days passed, the dragon still didn't come down, and the rooster's voice was hoarse, and he could cackle. But he didn't give up. He gets up before dawn every day, looks up at the sky and shouts: giggle. I wonder if the dragon in the sky can hear the cock crow. I wonder when the dragon in the sky can turn the horn into a rooster.
