What does a green dragon with a white tiger mean?

There seems to be an explanation in the book. . ：

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 black 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.

In Four Holy Beasts, China,

Another one that is often compared with dragons 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. Gold can crush wood, so feelings are more harmful. If we use the true meaning of 28 to make it one, then it will be seamless, and the dragon and tiger will change from crouching tiger to Dan. In the human body, the liver is the dragon and the kidney is the tiger, while the external Dan still takes the meaning of yin and yang, with the dragon as the lead and the tiger as the mercury.

Among many door gods, there is a special door god, which is specially used to guard the Taoist temple gate. They are what Taoism often says: "Left green dragon, right white tiger". For example, in the Taoist resort Qingcheng Mountain Ancient Road View (Shi Tian Cave), in front of the towering mountain gate, there are two temples. The left temple is a powerful dragon statue named Meng Zhang Shen Jun, and the right temple is a brave white tiger statue.

There is a saying in Taoism that dragons, white tigers, suzaku and Xuanwu are the guardians of the gods. These four gods actually come from the worship of ancient stars. The ancients divided the stars on the ecliptic (the celestial region where the sun and the moon passed) into twenty-eight constellations, which were called "twenty-eight nights"; Later, the twenty-eight schools and the four elephants merged to form the saying of "twenty-eight schools" and "four elephants". Among them, there are seven places in the East-Jiao, Kang, Shi, Fang, Xin, Wei and Ji. The ancients imagined it as Jackie Chan. Because it is located in the east, according to the theory that the five elements of Yin and Yang are matched with five colors, the east is blue, so it is called "Qinglong". In this way, there are basalts in the north, white tigers in the west and suzaku in the south. Qinglong, Baihu, Suzaku and Xuanwu are collectively called the "four elephants", also known as the 44,000 gods. Generally, the gods of the four directions are often used in military ranks and ranks, and become the patron saint of marching and fighting. QuLi still said, "all right. The former Zhu bird (sparrow) is behind Xuanwu, and the left Qinglong is right white tiger, swinging on the ground. " Chen Man noted, "Yes, the army will leave. Suzaku, Xuanwu, Qinglong and Baihu are also well known. " He said, "Let all the flags fly, Dragon Flag Nine, Sparrow Seven, Tiger Six, Tortoise and Snake Four." In other words, its manifestation is to draw "four elephants" on the standard to show the front, back, left and right military formations, boost morale and achieve invincible goals. Notes on the Thirteen Classics? The Book of Rites Quli said: "If birds fly, like the poison of turtles and snakes, dragons and tigers are excited, which is not comparable to these four things." It can be seen that its role is great.

After the rise of Taoism, Qinglong, Baihu, Suzaku and Xuanwu were included in the list of their gods, and they were regarded as the gods of guards to demonstrate their military majesty. "Bao Puzi Miscellaneous Answer" depicts the image of the old gentleman in Taishang, saying: "There are twelve dragons on the left, twenty-six white tigers on the right, twenty-four suzaku in front, and seventy-two basalts behind." Very imposing, really imposing. Later, the four elephants were gradually personified and had their titles. Qinglong was named "Meng Zhang Shen Jun", Baihu was named "Shen Jun of Prison Soldiers" and Suzaku was named "Ling Shen Guang Jun". Xuanwu is the "Ming King". Soon, the belief in Xuanwu (Zhenwu) gradually expanded, and it stood out from the four elephants and became the "Great Emperor". Qinglong and Baihu are included in the list of door gods, specifically guarding the Taoist temple gate. Fan Zhineng's Yueyang Lu Shengzhi in the Song Dynasty said: "I have two gods, namely the Qinglong and the White Tiger." Yao Ming Zong Yi's "Notes on the View of Changshu Private Records" said: "There are two great gods in the View Gate, Alina Zhang, the god of Qinglong, and, the god of white tiger." Among many door gods, there is a special door god, which is specially used to guard the Taoist temple gate. They are what Taoism often says: "Left green dragon, right white tiger". For example, in the Taoist resort Qingcheng Mountain Ancient Road View (Shi Tian Cave), in front of the towering mountain gate, there are two temples. The left temple is a powerful dragon statue named Meng Zhang Shen Jun, and the right temple is a brave white tiger statue.

However, some people think that the attributes are Lei Long, Hu Feng, Fire Phoenix and Water Turtle. Generally, water matches fire and thunder matches wind.

Since ancient times, the dragon and tiger have been enemies, and many idioms have explanations, such as entering the dragon, jumping the dragon and jumping the tiger.
