"The Nine Dragons groaned in shock, and once they entered the flood, they turned into the Yellow Dragon. In the Purple Heaven Palace, it was often heard that Nuwa had also made a contribution to the creation of people. The Heavenly Dao also speaks of the establishment of the human race, the Three Emperors and Five Emperors Xia Shang Zhou. Fu Zhou extinguished the Shang sealing god and expounded the two sects fighting divine powers. Flourishing to the extreme is also extinguished, turning around the Qiankun I Huanglong. ”

The yellow dragon mentioned in the poem is the dragon ancestor of Chinese myths and legends- Ying Long. The Ying Dragon is a winged dragon in ancient legends, also known as the Flying Dragon, also known as the Yellow Dragon. According to legend, Ying Long, as a general of the Yellow Emperor, killed Xuan You in the Battle of chasing deer, and also used his tail to draw the land into a river, and helped Dayu to control the water. Ying Long himself belongs to the five elements, juxtaposed with the four spirits and four elephants of heaven, in the center, in charge of the clouds and rain of heaven and earth, and the blessings and well-being of the world. There are two kinds of Ying dragons, one is born of Mao Calf and Yu Jia, born of phoenix and unicorn; the other is the dragon cultivation of 1,500 years, the dragon 500 years is the horned dragon, and the horned dragon is the Ying dragon.
Ying Long first appeared in the human world during the Yellow Emperor period, and is recorded in both the Classic of Mountains and Seas and the Records of History. To the effect that the tribes of the Yellow River Basin, led by the Yellow Emperor, fought against the tribes of the Yangtze River Basin headed by Xuan You, and both sides invited various gods and immortals to assist in the war. The Ying Long on the Yellow Emperor's side was good at "animal water", and Xuan You Nafang also invited the gods who were good at calling the wind and rain, and their skills were better than the Ying Dragon, so the heavy rain drifted to the Yellow Emperor's side.
After the Yellow Emperor was in a weak position, he asked the Heavenly Lady "Ray" to help stop the heavy rain, and took advantage of the situation to annihilate the Xuanyu tribe in one fell swoop. Ying Long made great contributions in this battle and killed Xuan You and Quao's father. Due to the exhaustion of his strength in the battle, Ying Long was no longer able to flapp his wings and fly back to the Heavenly Garden, so he quietly came to the south and lived in the mountains. Because the dragon is water-based, the place where it lives, the cloud moisture will naturally gather, which is why the south is rainy.
After recovering his strength, Ying Long came back to help Dayu check the water vein, open the river, and became one of the heroes of Dayu's water control. According to the book of Shuyi, "The water flies have been transformed into jiao for five hundred years, jiao for a thousand years into a dragon, a dragon for five hundred years as a horned dragon, and a thousand years as a ying dragon."
Of course, some people think that Ying Long may refer to the ancient kingdoms of ancient times - Ying Long Clan and Ying Guo. The great poet Qu Yuan, in "Heavenly Questions", expressed his confusion and doubts about how the dragon helped Dayu to control the water, how to use his tail to draw rivers on the ground, and how to divert the flood into the sea.
According to legend, Ying Long is the divine dragon of the Yellow Emperor in ancient times, this divine dragon is also known as the Yellow Dragon, and the Yellow Dragon is the Ying Dragon. Ying Long is the essence of the dragon, so it has wings, scaly spines, a large and long head, a small nose, eyes and ears, large eye sockets, high eyebrow arches, sharp teeth, a protruding forehead, and a long tail tip.
Ying Long often appears on the bronze ware of the Shang Zhou Dynasty, the jade carvings of the Warring States, the stone carvings, paintings and lacquerware of the Han Dynasty. The earliest image of YingLong belongs to the pterosaur pattern found in Inner Mongolia, dating back to 7400 years ago.
In Han mythology and legend, the dragon is the king who rules the water tribe, rules the rainfall of Xingyun, and is also one of the four spirits in ancient Chinese mythology. In Taoism, the East Sea Dragon King is named Ao Guang, the South Sea Dragon King is named Ao Ming, the West Sea Dragon King is named Ao Shun, and the North Sea Dragon King is named Ao Ji, which is called the Four Seas Dragon King. The duty of the Dragon King is to raise clouds and rain, to control the wind and rain between heaven and earth, and the Dragon King's rule of water has become a common belief of the Han people.
The "Dragon King Pin" in the Taoist "Taishang Dongyuan Divine Mantra Sutra" says, "The land is hot and dry, the grain is not harvested, and the three threes and twos do not know how to count the time", the Yuan Shi Tianzun came to the land with five colored clouds, and preached the Fa-rectification with the Dragon Kings of the Heavens, saved all sentient beings, and the torrent of heavy rain and rain was sweet at the right time. The East Sea Dragon King is the head of the four kings, because the Dragon King is afraid of fire, and the East Sea Dragon King holds fire in his hand.
"The father of the dragon has no dog", since the dragon is so powerful, it can swallow clouds and spit fog, stir up wind and waves, and be admired by Chinese folk for thousands of years, its son is naturally not an idle person. The so-called "nine sons of the dragon" means that the dragon gives birth to nine sons, and the nine sons are not dragons, each of which is different. And the dragon gave birth to nine sons is not the dragon just gave birth to nine sons. In traditional Chinese culture, nine is used to represent a lot, has a supreme status, nine is an imaginary number, but also a noble number, just like the emperors use the nine five to elevate themselves, so nine is used to describe the dragon. The saying that the dragon has nine sons has a long history, but there has been no exact version of which nine sons it was until the Ming Dynasty.
Because Ming Xiaozong could not figure out the names of the nine dragons, he went to ask Li Dongyang, a cabinet scholar at the time. Li Dongyang received the emperor's "Imperial Book Post" and asked "The Names of the Nine Sons of Longsheng", he seemed to remember that he had seen it in the "Miscellaneous Books" when he was a teenager, but he could not answer it in a hurry, so he asked the editor Shu Luoxuan. Luo Xuan said that he had heard his teacher say it, but he only remembered five or six of them, so he asked the official Liu Ji again. Liu Ji said that he had an old book in his home, "this phrase was recorded on the book", and when he took it and saw that it did have the name of "Nine Sons", it was not written down in the Book of He, and there was no way to check it.
The emperor's inquiry could not be delayed for too long, and Li Dongyang had no choice but to reply on this basis. According to legend, the dragon gave birth to nine sons, each of which had its own good.
The boss is a prisoner of cattle, good music in his life, and the beast carved on the head of the huqin is his relic. The old man is blind, and he is easy to kill in his life, and the dragon swallowing mouth on the handle of the sword is his relic. The old third laughed at the wind, his life was dangerous, and the beast in the corner of the temple was his relic. The old fourth Pu Prison, who has a good life, is his relic on the beast button on the clock. The old five foxes, who are easy to sit in their lives, are now the buddha lions who are his relics. Under the old six hegemons, he was born with a good weight, and the beast foot of the monument is his relic. The old seven foxes, who lived a good life, are now the lion's head on the prison gate is his remains. The old eight-fold, good at life, and the dragons on both sides of the stele are his relics. The old nine clams kissed, and the life was easy to swallow, and the head of the beast in the present temple was his relic." Of course, in the ancient Chinese mythology, there are many versions of the nine sons of the dragon, it is said that the gluttony, cattails, etc. are one of the dragons, as for this many dragons, whether it is the dragon ancestor Ying long born, or the dragon king of the four seas, the author does not dare to say anything, but also ask the readers to advise the gods.
