Xuanwu, one of the four celestial spirits in ancient China mythology, also known as tortoise and snake, originated from the worship of stars in ancient times, which refers to dividing twenty-eight lodges into seven northern Xuanwu lodges according to the southeast and northwest of the four elephants.

In the traditional culture of China, the four elephants refer to Qinglong, Baihu, Suzaku and Xuanwu, representing the east, west, north and south directions respectively. Xuanwu in the north is based on the eight diagrams and the main water in the five elements, symbolizing the old yin in the four elephants and the winter in the four seasons, and is also the land of heaven in the north.

Xuanwu is a spiritual thing composed of turtles and snakes. Xuanwu originally meant Xuanming, and the ancient sounds of Wu and Ming are interlinked. Wu means black; Ghost means yin.

Cultural characteristics

Place name: Xuanwu Emperor Dojo is located in Wudang Mountain, Hubei Province, so Wuhan embraces Guishan and Sheshan across the river.

Totem culture: In ancient China, turtles and snakes were considered as spirit beasts, symbolizing longevity. Before the Han Dynasty, nobles often wore jade turtle ornaments. In Japan, influenced by ancient China, turtle patterns are often used to name and make badges.

The twenty-eight lodgings are divided into four groups, namely, seven lodgings in East Black Dragon, seven lodgings in North Xuanwu, seven lodgings in West White Tiger and seven lodgings in South Suzaku. The ancestors regarded the dragon as the length of the scale worm, the phoenix as the king of all birds, the tiger as the length of all beasts, and the turtle as the king of worms, which were collectively called the four spirits.
