Divination is the symbol of divination as a whole. The Book of Changes is divided into four disciplines, namely, image, mathematics and physics, in which the image is to see the meaning of divination. It takes a lot of imagination to read hexagrams, so we should consider problems in an eclectic way and not stick to the rules. Conservative people will feel that they have no ideas when reading hexagrams.
There are sixty-four hexagrams in Zhouyi, and each hexagram has a name.
Dry divination has three yang, pure yang is vigorous, so it is heaven, and generally the circle moves endlessly, so it is round. Everything is born, such as a monarch governing all peoples, and a father governing a family, so it is the monarch's father.
Pure yang is strong and solid, so it looks like jade ice. Yang Sheng is very red, so it is fiery red. Vigorous is a horse, and the fruit on the tree is round, so it is a wood fruit. Therefore, everything in the world that is positive, energetic, authoritative, masculine, precious, rich, cold, hard and fragile belongs to dry divination.
The Book of Changes said in the Biography of Eight Diagrams: "Dry is heaven, round, monarch, father, jade, gold, cold, ice, red, good horse ... and fruit."
Dry represents the sky, Kun represents the earth, Xun represents the wind, earthquake represents the thunder, ridge represents the water, distance represents the fire, root represents the mountain, and change represents the ze.
Gossip is the foundation of the Yi-ology system. The pre-Qin Yi-ology was mainly "three changes", namely, Lianshan in Xia Dynasty, Tibet in Shang Dynasty and Zhouyi in Zhou Dynasty. Later generations are familiar with Zhouyi, which can be divided into Yijing and Yi Zhuan.
