There are many legends about dragons and many stories about the origin of dragons in the four ancient Chinese beasts: Qinglong. Some said it was imported from India, while others said it was transformed from China. India itself is said by the dragon god, but the status of dragons in India is not high, and there is a real thing-python. In the era when the Five Elements Theory prevailed, the story about Qinglong began to spread slowly. According to the Yin-Yang and Five Elements, the Five Elements assigned five colors to the Southeast and Northwest Middle Schools, and each color was equipped with a beast and a god. East is cyan, with dragons, west is white, with tigers, south is scarlet, north is black, with martial arts, and yellow is the central positive color. Among the four gods, according to Shan Hai Jing,' Southern Zhurong is a beast with a face and rides two dragons.' ; In the west of Ru Shou, there is a snake in the left ear. You can ride two dragons. ; In the East, there is Ju Mang, who is a bird and a man, riding two dragons. ; In the north, Yu Jiang, with dark hands and feet, rode two dragons. Interestingly, the dragons in Shan Hai Jing are all riding, while the snakes of the same kind with him are all being led or held or held or wrapped around their necks, which shows the difference between them. However, the five gods are different from the four gods, so I won't elaborate here. Suzaku, Xuanwu (black tortoise snake, martial arts means tortoise snake), Qinglong and Baihu represent the twenty-eight lodges in four directions respectively. The dragon is the seven lodges in the East-horn, clang, car, room, heart, tail and dustpan. These seven lodges are all dragon-shaped. As can be seen from their meanings, horns are the horns of dragons, and clanging is dragons. There is still a part of the dragon's heart, which some people call' fire', which is related to sunny and rainy days, and because Qinglong is a wood, it is also the age of Jupiter. After the rise of Taoism, these four spirits were also given names to facilitate human beings to call them. Qinglong is called Meng Zhang, White Tiger is called prison soldier, Suzaku is called Lingguang, and Xuanwu is called Zhiming. In many dynasties, emperors took Qinglong as their national title, such as Wei Mingdi of the Three Kingdoms, and there were also records that the Xia Dynasty belonged to the Mude Dynasty, so he had' After ancient times in China, those with horns on their heads were male dragons; Double horns are called dragons, and single horns are called dumplings; Those with horns are poisonous snakes. In ancient times, there were often large and small Ssangyong in Yu Pei, and it was still called mother and son poisonous snakes. The status of dragons is much higher than that of India. Because it is sacred and supreme in the dragon, it is also a symbol of the emperor. It is also the representative of the east, and the five elements belong to wood. Because cyan belongs to wood, there is the saying of Zuo Qinglong and you Bai Hu. Among the 28 stars, seven stars in the East-Jiao, Kang, Bian, Fang, Xin, Wei and Ji-are used among the stars. The ancients imagined them as Jackie Chan. Because it is located in the east, the five parties are colored according to the theory that the east is blue, so it is named' Qinglong'. There is also a folk saying that dragons are lustful, that is, having sex with cows will give birth to unicorns, and having sex with pigs will give birth to elephants. The so-called dragon gives birth to nine sons, unlike the dragon's saying, this is the case-the eldest son is called prison cow: he loves music, so he often stands on the head of the piano. Such as Hu Qin of Han nationality and Qin Sang of Bai nationality. Ma Touqin in Mongolia may also be a variant of prison cattle. The second son's name is Chipi: He loves to kill people, so he is often put on weapons to deter the enemy. At the same time, it is used in ceremonial ceremonies to appear more solemn. The third son's name is Mo Chifeng: it is an animal-shaped dragon, which looks a bit like a dog. It is good at viewing, so it is often placed in the corner of the temple. It is said that it can kill demons and eliminate disasters. The first Si Er is not old: people like to growl, so they put it on the clock, mostly the image of not old. It is said that it lives by the sea, but it is very afraid of whales. Once a whale attacks, it screams in fear. Therefore, people make the wooden pestle into the shape of a whale, which makes the bronze bell particularly loud. The fifth son is a sister-in-law: shaped like a lion. It's imported, and it was introduced to China with Buddhism, so it's a bit like Buddha. It is so quiet and likes fireworks. Therefore, it is often placed on the Buddha's seat or incense burner to protect the dharma. Liuzi is a bully: also called tortoise, he looks like a tortoise. Legend has it that in ancient times, it often carried three mountains and five mountains to make waves. After being appeased by Yu Xia, he made many contributions to Yu Xia. After flood control became an attack, Yu Xia accepted its advantages and let it recover on its own. So China's stone tablets are mostly carried by it. The seventh son is an armadillo: also known as the Charter, it looks like a tiger. According to legend, it upholds justice and can distinguish between right and wrong, so it is placed on the top and bottom of the prison gate, in the lobby and at the top of the sign of silence and avoidance when officials patrol, in order to maintain the awe-inspiring atmosphere of the court. The eighth son is a burden: because he loves literature, he put it in two stone tablets. Mozi is a kiss: also known as fish-shaped dragon, with a tail. According to legend, it was introduced from India with Buddhism around the Northern and Southern Dynasties. It is something under the rain god in Buddhist scriptures, which can put out fires. So the kiss was changed, so it was placed at both ends of the roof to eliminate disasters and put out fires. The white tiger is in Four Holy Beasts, China, and another one that is often compared with the dragon is the' white tiger'; The tiger is the leader of all animals. Its strength and legendary ability to subdue ghosts make it a beast belonging to Yang, and it often goes out with dragons. The cloud follows the dragon and the wind follows the tiger' to become the best partner for subduing ghosts. And the white tiger is also the god of war and war. White tiger has many magical powers, such as avoiding evil, avoiding disasters, praying and punishing evil, promoting good, making a fortune and getting married. And it is one of the four spirits, and of course it is also changed from the stars. Among these 28 stars, there are 7 in the west: osmium, building, stomach, ang, bi, Gou and Shen. Therefore, it is the representative of the west, and its whiteness is due to the west. The five elements belong to gold and the color is white. So it is called white tiger not because it is white, but because it comes from five elements. In addition to the four spirits in Taoism, including dragons and white tigers, and even when Feng Shui masters explore cemeteries, the terrain protruding from the left and right sides in front of the terrain can be used as burial rooms, which have unique titles, called Zuo Qinglong and Right White Tiger, to take the meaning of their guards, and also have the same decoration in the court. The left and right pillars are painted with dragons and white tigers to suppress evil spirits. After the rise of Taoism, dragon and tiger were borrowed as Taoist alchemy terms, meaning "lead, mercury, fire, water, yin and yang" and so on. Taoist alchemy is divided into two parts: internal alchemy and external alchemy (I'm not sure). As far as Yin-Yang and Five Elements are concerned, Inner Dan means that dragons are born in fire, so the cloud' dragons are born in fire', while tigers are born in ridges and ridges belong to water, so the cloud' tigers are born in water'. After the two elements are combined, one yin and one yang are mutual. Another way of saying this is that sex belongs to wood, and wood represents the East. In divination, it is an earthquake, so it is a dragon. Love belongs to gold, gold represents the west, and the hexagrams are exchanged, which is golden white, so it is called white tiger. In the eyes of the ancients, the tiger is a terrible thing and a respectable thing. The terrible thing is that it will eat people and animals. Respectably, it can ward off evil spirits because of its great power. In some ancient books, such as Ying Shao's Custom Yi Tong. Sacrifice in the Eastern Han Dynasty: "Draw a tiger on the door, ghosts dare not enter", "A tiger is a penis, and all animals are long. Can resist sharpness and eat ghosts. Today, people have to burn tiger skin to drink after they die. Beating its paws can also cure evil. This is also a fact. " The ancients also thought that the white tiger was an auspicious feeling:' virtue is a hundred birds and beasts.' The original West Star gods were bears and owls, and later, because of the totem of the ancient Qiang people, when bears became dragons. When the Yellow Emperor developed eastward, the dragon totem was brought to the east and merged with the' Oriental Black Dragon Constellation', and Zhu Bird became the new home of the celestial phoenix totem when the south was unified, and eventually became a' dragon and phoenix' because of the integration of the two tribes. As an ancient totem, it is the East Phoenix and the West Dragon, and as an astrology, it is the East Black Dragon and the West Zhu Bird. After the Zhou Dynasty, the feudal system was formally established, and the five elements thought also became mature. The astronomical phenomena were re-divided, and the Zhu bird was placed in the south, where it was sacrificed with Zhu Rong Vulcan. The west worships the white tiger. In the tribal struggle and migration, the dragon in the northwest moved eastward, the phoenix in the east moved southward, and the tiger in the south moved northward, showing a great conceptual movement throughout the country. By the Han dynasty, the concept of five elements had become a unified thought, and with Xuanwu, the' God of the Four Sides' was completed.
