In ancient times, there was no equal village, the Dong family lived on the hillside, a small counterfeit product, only a dozen families. There was a small counterfeit product in the offspring, named Buka, married a wife, named Pei Guan. The husband and wife are very loving, almost inseparable. When the two came back from work, one picked firewood, one carried grass, one carried a hoe, and one petunian, always following them back and forth. Pei Crown was very beautiful, and when the husband and wife crossed the bridge, the fish in the river jumped out of the water with envy to see them.

One morning, the river suddenly rose sharply. Buka and his wife were in a hurry to go to work in the western mountains, but they couldn't take much care of it. They walked together to the small wooden bridge in front of the village. Just as they reached the center of the bridge, a sudden gust of wind blew, and Buka could not open his eyes, and Pei Guan fell into the river with an "oops" sound. Buka opened his eyes and saw that his wife was gone. Knowing that he had gone down the river, he jumped into the water and dived into the river. However, after searching back and forth for a few laps, he couldn't find it. The villagers knew and came to help him look for it. After searching for a long time, they still couldn't find Pei Guan. What was going on?

It turned out that there was a crab spirit in the depths of the river and rolled Pei Guan into a cave at the bottom of the river. All of a sudden, the crab spirit turned into a beautiful descendant and wanted Pei Guan to be his wife. Pei Guan refused and slapped him. He immediately showed a fierce look and threatened Pei Guan. Pei Guan cried and cursed, and the sound of crying and cursing spread from the bottom of the river to the ears of a flower dragon upstream.

At this time, the wind and rain were mixed, and the waves were rolling, and I saw a flower dragon in the waves, looking around with its head held high. The dragon head looked to the left, the waves hit the left, the landslide on the left, the dragon head looked to the right, the waves rushed to the right, and the right bank cracked. The small wooden bridge had long been swept away by the waves. Everyone was terrified. But when the dragon head came to the beach of Buka, the dragon head clicked a few times and the waves calmed down. Then, the dragon flower made a circle on the water and rushed to the bottom of the river. Immediately, the sound of "bones and bones" at the bottom of the river continued to come, and the vortex flew one after another. Then, a black smoke came out of the water, and it rose into the air and turned into a dark cloud. The flower dragon rushed into the air, tossed its body, pressed down the black cloud, and finally pressed it into its original shape. It turned out to be the black crab as big as the top of the drum tower. The black crab fled in panic and climbed a cliff three meters high. The flower dragon went down to the water and somersaulted, and with a swing of its tail, it swept the crab into the water again. After a few rounds, the crab was exhausted and swayed towards the bamboo forest, trying to use the bamboo to block the flower dragon. But the flower dragon jumped up, opened its mouth and sprayed water, causing the bamboo forest to fall down one by one, and the crab fell into the river again. After the dragon flower caught up with the bottom of the water, the waves rolled down the river, and the black crab was no longer seen. Later, not far from the river, a black stone in the shape of a crab was exposed, which was where the flower dragon held the crab essence. This stone was later called the crab stone.

When the river was calm, she heard the voice of a woman on the opposite beach. Buca saw that it was her wife. Buca called a few people to swim over immediately. After going ashore, Pei Guan said to Buca, "Thanks to Hua Long for saving her!" Everyone knew that Hua Long had saved her, and they were very grateful to Hua Long. At this time, Hua Long flew back upstream, nodding to the people from time to time.

This story quickly spread throughout Dong Township. Everyone converted the small wooden bridge near the water surface into a large wooden bridge like a sky corridor, and carved the pattern of flower dragons on the four middle pillars of the bridge, wishing the flower dragons would always be there. After the completion of the large wooden bridge like a sky corridor, a grand celebration ceremony was held, which was very lively. At this time, colorful clouds floated in the sky, shaped like long dragons, and when everyone looked closely, it was the flower dragon that came back to visit everyone. Therefore, later generations called this bridge Huilong Bridge. Some places are also called flower bridges, and because the bridge can shelter from wind and rain, it is also called wind and rain bridges.
