Bagua is a set of symbols in ancient China. It consists of three long paintings or eight patterns, and is used for divination and symbol in China and Japan. With "one" for Yang and "-"for Yin, three such symbols form eight forms, which are called Eight Diagrams. Each six-pointed star represents something. Dry represents heaven, Kun represents earth, ridge represents water, far represents fire, earthquake represents thunder, root represents mountain, Xun represents wind, and dui represents swamp. Eight trigrams collocate with each other to form sixty-four hexagrams, symbolizing various natural phenomena and personnel phenomena. It is discussed in detail in the Book of Changes.
