There was a family on the Yellow River who made a living by cutting reeds and making curtains and dustpans. They lived in poverty. One day, his son was cutting reeds by the river. The scorching sun made him dizzy, so he sat down to rest. He looked at the river in front of him shining with sparkling waves in the sun, and remembered that his father had said that there were many treasures in the deepest part of the river, but no one dared to go there because there lived a ferocious black dragon called Lilong.
He thought that if he could dive to the bottom of the river and find treasures, our family would not have to work all day long and still not have enough to eat like we do now. It was better to go out and give it a try. He suddenly took off his clothes and plunged into the cold river. At first, he could still see small fish swimming around. As he went deeper, the light became darker and darker, and the water became colder and colder. Finally, he couldn't see anything anymore, and everything was pitch black.
He was a little scared and didn't know where to swim. At this moment, there was a round object shining not far away. If you look carefully, ah, it turns out to be a pearl! He held his breath and swam over, hugged the pearl with both hands, and pulled hard, and the pearl came into his arms. He quickly surfaced, landed and ran home. As soon as his father saw the pearl, he asked him where he got it. He told his father everything about it.
My father heard this and said: "What a danger! This pearl worth thousands of gold grows under the black dragon's chin. The black dragon must be asleep when you pick it. If it is awake, you can He's dead."
