What do you mean by left Qinglong and right 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". Usually, the left green dragon and the right white tiger represent the left and right positions, not the real green dragon and white tiger.

Twenty-eight inns were established in ancient China, which were divided into four groups with seven stars in each group. These four groups are the stars in the sky in spring, summer, autumn and winter.

Each season is equipped with an animal and an orientation (see attached figure).

Spring matches the East, and its spirit is Qinglong, because Qinglong represents the vitality of spring and the growth of all things. The vitality of Qinglong is equivalent to the germination of flowers and plants in spring. As for summer, the weather is hot, so it is represented by Rise of the Legend.

And birds are particularly active in summer, so the spirit of summer is Suzaku. Suzaku is a red firebird. In addition, summer is accompanied by the south.

Autumn is full of cold air, and there are more executions in ancient times than in autumn, which is called autumn decision. When autumn comes, yellow leaves fall. So [White Tiger] just represents the loneliness and cold breath of autumn. Autumn is accompanied by the west.

Winter is accompanied by the north. Flowers and trees are no longer lush in winter, and animals hibernate, just like collections. Therefore, Xuanwu just represents this season. The so-called [Xuanwu] is a big black turtle, because turtles have a collection image. Black represents convergence.

Qinglong: Qinglong is one of the four elephants in China traditional culture. According to the theory of five elements, it is a spirit beast representing the East. Qinglong is both a name and a family, and its orientation is east to right, representing spring.

In the 28 constellations, Qinglong is the general name of the seven oriental stars (horn, sound, mutual, room, heart, tail and dustpan). Dongqisu is also called the Black Dragon. The Dongqisu in the Black Dragon-Jiao, Kang, Bian, Fang, Xin, Wei and Ji-is very dragon-shaped. As can be seen from their meanings, Jiao is the horn of the dragon, Kang is the neck, the side is the root of the neck, and the square is the arm, flank and shoulder.
