Bagua originated from the ancient Chinese concept of the basic universe formation, the relationship between the earth's rotation (yin and yang) corresponding to the sun and the moon, agricultural society and the philosophy of life. Bagua represents the yin and yang system of things changing themselves, using "one" to represent yang and "- -" to represent yin. Three such symbols are used, combined in parallel according to the changes of yin and yang in nature, to form eight different forms, called Bagua.
The eight hexagrams are: Qian, Kun, Xun (xùn), Zhen; Kan, Li, Gen (gèn), Dui.
Each hexagram represents a certain thing. Qian represents heaven, Kun represents earth, Xun (xùn) represents wind, Zhen represents thunder, Kan represents water, Li represents fire, Gen (gèn) represents mountain, and Dui represents lake. Like the current atomic and molecular theory, it was created by the ancients to explain various material compositions and natural phenomena.
