What is the main explanation?

"Yi Yi" is the term of "One Grass and Eight Chambers Method", which is mainly based on the move of this divinatory symbol. It is also based on divination. This is discussed in detail in Zhu's Zhouyi Shenwu. When you use the method of divination, you change three hexagrams, you repeat the steps, and six hexagrams become eighteen. When you get six hexagrams, it becomes a hexagram, which is called a body hexagram. Lao Yang, the old yin in body divination, is stubborn. That is, strong things are easy to get old, and extreme things will be reversed. When you move, you become stubborn, and the hexagrams you become are called hexagrams. The law of divination is to judge good or bad according to the change of action. "enlightenment" is based on seven changes: < 1 > one change, which is occupied by the original poem (judging from the occupation of the garden, the same below. ) < 2 > for those who change their minds, this is the main slogan, and the above slogan is the main slogan. < 3 > 3 > > > > > > > > > > > > > > >12 > > > > > > > > > > >/kloc. 〈 7 〉 Six ideas remain unchanged, and this idea accounts for.

"Shang" is the main explanation of Zhouyi Shenwu. However, Fang Jingyi has reviewed more than this, relying on the flying of six beasts and ten gods, and the birth of five elements.
