Legend of the origin of kites (simple) 20 words

According to legend, in the Eastern Han Dynasty, there was a clever carpenter named Li who often used wood or bamboo as toys for his son in his spare time. One day, carpenter Li accidentally caught a little Shan Ying in order to chop wood for a paper mill in the forest to make a wooden cabinet, and took it home to play with his son. To prevent Shan Ying Jr. from flying away, he tied one of Shan Ying Jr.' s paws with a long rope. My son, holding the rope, was having a good time chasing flying Shan Ying in the yard. No, he accidentally fell, the rope slipped from his hand and the flash-forward flew away. My son often cries. Carpenter Li promised to be a Shan Ying to play with his son in order to appease him. A few days later, carpenter Li made a Shan Ying out of bamboo sticks and gave it to his son. But my son only played for a while and then stopped playing. He said gloomily, "It can't fly at all. It's not fun at all. I want Shan Ying who can fly. " Carpenter Li is worried now.

Half a month later, carpenter Li sent the finished wooden cabinet to the paper mill. Just as I was about to leave, there was a sudden gust of wind, and some papers that had not been bundled before were blown around in the yard. Carpenter Li was overjoyed at the flying paper. When the wind stopped, he hurried home with some papers. He asked an artist to draw a mountain shadow on the paper, then made a hole in the paper with a thin thread, tied it to the paper, and gave it to his son happily. But I don't want to, because there is no wind at this time, no matter how he pulls or throws, the paper can't fly. He was very disappointed.

Neighbors came to see him in the evening and wanted him to go out to sea tomorrow to help close the net. The next morning, carpenter Li went to his neighbor's house to help. As soon as Carpenter Li went out, his son chased him out and asked him when he could be a Shan Ying. Carpenter Li had to perfunctory.

He and his neighbors came to the seaside. The wind that day was just towards the sea, and it was very windy. He got on the boat, thinking about how to make a Shan Ying for his son. The neighbor raised the sail and the boat sailed into the sea under the action of the wind. Unexpectedly, the bottom rope of the sail was not fastened properly, and the sail was blown up, and the ship became an oblique angle. Under the action of the wind, the bow was lifted several times and almost capsized, which was extremely dangerous. He and his neighbors desperately pulled down the sail rope to fasten it. On the way back, carpenter Li was in shock. He looked straight at the bow and waited for a while, thoughtfully. Suddenly, he seems to have found something. He suddenly stood up and startled his neighbors. "If the sail is at an oblique angle to the wind direction, the ship will have upward power. If paper is at an oblique angle to the wind, can it fly? " The idea was deeply imprinted on his mind.

Back home, carpenter Li began to think hard about how to make the paper oblique to the wind. Finally, he decided to tie three lines on the paper into a triangle, with the top one short and the bottom two long, and then connect the three lines with one line. As soon as this line is pulled, the paper will form an oblique angle with the wind, just like a sail. There must be upward force. After several experiments and improvements, the paper Shan Ying really flew upwards.

One day at noon, he just woke up and saw his son fiddling with the Shan Ying paper. He found some pieces of cloth and added a tail to the paper Shan Ying. He immediately asked his son what he was doing. His son smiled and said to him, "Shan Ying has a tail, which makes him look like Shan Ying ..." To his surprise, it was this little improvement of his son that completely solved the problem of the eagle's head down and really flew. One day, carpenter Li took his son to play paper Shan Ying. After reading it, the neighbor's children loudly asked the adults for it. Neighbors came over and asked with interest, "Carpenter Li, what are you flying?" Carpenter Li thought for a moment and said, "I've heard of wooden harriers." I am made of paper. Let's call it a paper owl. " This simple paper kite is the embryonic form of modern kite.
