According to "Nanchong County County Records", "Longmen Township Township" records, Longmen Township was called Anfu field, the Tang Dynasty when the Jialing River diversion of Anfu field north of the Pangjiashan break, the formation of ghostly Dragon Gate Gorge, Anfu field from the name of the Longmen field. Longmen Gorge between the gorges underwater boulders across the threshold, every summer and fall when the water rises, the torrent swooped over the "threshold of the water", splashing the shocking splash, then there will be groups of red carp from the bottom up, in front of the "threshold" jumping, striving for the upper reaches. This spectacular spectacle was later interpreted into many versions of the "Carp Jump Dragon Gate" myth and legend. Legend has it that the carp jumped over the "water threshold" after the dragon robe, from fish to dragon. At present, Longmen Town is still well-preserved with this legend related to the "Dragon Gate Gorge", "Dragon Gate Tuo", "Water Threshold", "Carp Jump Dragon Gate "
When the legend of the Dragon Gate Gorge is told, it is said that the Dragon Gate Tuo, the Water Threshold, and the Carp Jumping Dragon Gate are the most important features.
When the fish from the water was brought up, but also jump around, the reason is that the fish swimming in the water, the muscles of the body is always a stretch, wagging head and tail, in order to make it forward in the water. When it just left the water, still like in the water, doing the same action, but because there is no resistance by the water, so the shaking action is particularly large, and then if encountered such as the ground, the board and other solid objects, there is the phenomenon of jumping about. In fact, modern science can be cracked "carp leap Dragon Gate" this mystery: here said "carp" is actually "tuna", or "Acipenser fish ", also known as "sturgeon" or "yellowtail", also known as sturgeon. Sturgeon is the river and sea back to swim fish, body length of about two meters, the largest can be more than 5 meters long. China's rare animal Chinese sturgeon, northeast sturgeon, Yangtze sturgeon is this kind of fish. Because the ancient big carp is also known as "Acipenser", so the ancients will be "tuna Acipenser" and big carp mixed, rumored to be "Carp leap Dragon Gate".
"Bamboo Book Chronicle" is the work of the late Warring States period of Wei historians, the book "Dragon Gate Red River" records, indicating that at that time, "carp jumped the Dragon Gate" myths have not yet been formed. And "fish into a dragon" records from the Han Dynasty canon, so the formation of myths in the early years of the Western Han Dynasty, and may be with the early Han Dynasty, the concept of worship of dragons strengthened.
Li Bai of the Tang Dynasty wrote a poem: "The three-foot carp in the Yellow River, originally residing in Mengjin, did not become a dragon, but returned to accompany the ordinary fish."
The Northern Song Dynasty's Yuanfeng Nine Regions Zhi reads, "There is a dragon gate 30 miles north of Guozhou."
The Sanqin Records: Longmen Mountain, in the eastern boundary of the river. Yu chiseled the mountain to break the gate more than a mile wide. The Yellow River flows down from the center, and the two sides of the river are not open to cars and horses. In the spring of every year, there are yellow carp, from the sea and all the rivers compete to go to it. In one year, only seventy-two people climbed to the Dragon Gate. The first time you go to the Dragon Gate. The first time you reach the Dragon Gate, there will be clouds and rain, and heavenly fire will burn your tail from behind, and you will be transformed into a dragon.
Translation:
The Dragon Gate is located in the boundary of Hedong. Dayu chiseled down Longmen Mountain and opened up the Dragon Gate, which was more than a mile long, and the Yellow River flowed down the middle, so that the two banks could not be passed by carriages or horses. Every year in the late spring there were yellow carp, scrambling from the sea and all the big rivers to come to the Dragon Gate. In a year, no more than seventy-two carp ascend to the Dragon Gate. As soon as it ascends to the Dragon Gate, clouds and rain follow it, and the sky sends down a great fire to burn its tail from behind, so (the carp) changes into a dragon. In the East China Sea, a large group of golden-backed carp, white-bellied carp, gray-eyed carp, heard that King Yu wanted to select a talented person who could leap onto the Dragon Gate to take care of the Dragon Gate, so they formed a group and swam upstream along the Yellow River. Have not seen the shadow of the Dragon Gate, that a gray suit carp will be the Yellow River in the mud and sand to beat dizzy, it turned the head, downstream, without effort and swim back to the Yellow Sea. Unfortunately, it ran into a sea monster with a big mouth, and then it died. But the gold back carp and white belly carp, set up a long serpentine formation, take turns to play the front, against the wind and waves, day and night, and finally swam to the foot of the Dragon Gate. They put their heads out of the water, looking up at the Dragon Gate God: only to see the magic of the Dragon Gate on both sides, each with an embracing thick white jade pillar. The jade pillar is carved with a vivid stone dragon. Dragon body wrapped around the jade column, circling up to the top of the column of 100 feet. Dragon Gate in the water waves, silver splash to the dragon head above, - just into the "two dragons playing pearls" of the strange color picture. The view was better than that of Penglai's fairyland. The carp, having seen the beauty of the scenery, applied to King Yu for the examination. King Yu was overjoyed at the sight and said, "Fish and dragons are born of the same species, and they become dragons when they leap to the Dragon Gate." Carp heard, immediately drum gills shake tail, make all the life force to leap upward, I did not expect just jumped out of the water more than ten feet high, fell down, fell on the surface of the water, the old pain old pain. But they are not discouraged, but day and night training hard to fall tail jump. So straight practice for seventy-seven forty-nine days, a leap of seventy-seven forty-nine feet high. But they were still far from reaching the hundred-foot dragon gate. Seeing that the carp were willing to practice hard kung fu, Dayu enlightened them and said, "What a big group of fish!" A golden-backed carp was greatly enlightened by King Yu's words, and said to the group of fish: "When King Yu said, 'What a big group of fish,' didn't he inspire us to make a group effort to jump up to the Dragon Gate?" The group of fish exclaimed in unison: "Many thanks to King Yu!" The carp were so happy that they waved their heads and tails, one by one, glaring, bulging their gills, and striking the water with their tails, only to hear the sound of "fattening" striking the water one after another. They jumped seven hundred and seventy-nine feet high, and in mid-air, one of them cushioned itself for the other, and then, after catching their breath, they jumped seven hundred and seventy-nine feet high again. Only two feet away, King Yu used his hand to fan over a breeze, the wind urged the fish to leap, the fish one by one jumped up to the Dragon Gate, which they aspire to day and night. But there was a golden-backed carp, which was the air cushion for all the fishes, who saw that all his companions had jumped up to the Dragon Gate, but he himself remained at the foot of the Dragon Gate. It thought, "Why don't I use the power of the water to jump up to the Dragon Gate? Coincidentally, the Yellow River water is rushing in the heart of the Dragon Gate on the boulders, wave splash dozens of feet high, the gold back carp violently out of the water, jumped on the crest of the wave, and with the tail slamming the tip of the wave, the fish body jumped up, I did not expect to leap to the blue sky between the white clouds. The fish leaped up and landed on top of the dragon gate, just like a dragon descending from the sky. Dayu saw, marveled at, then in this gold back carp head point red, a flash, fish and dragon change. In a flash, the fish and the dragon changed. The gold-backed carp turned into a golden dragon for good luck. Dayu ordered the golden dragon to lead the carp to protect the Dragon Gate. According to the legend of the old man, in the past, if people who fished on the Yellow River found a carp with a red color on its head, they would immediately put it back into the Yellow River. School enrollment out of the list, the name of the red point on the law comes from this.
