How to interpret Liu Yao

The original meaning of "Yi" is "intersection" and "effect", and "effect" is the "utility" produced by "intersection", which can be measured by global calculation and has different interpretations according to different methods, systems and positioning. Yao (Yao; Cantonese food? Au), the two symbols of the Book of Changes, one is "-"and the other is "-". There is no word "yin and yang" in the Book of Changes, but it was called "Yang" and "Yin" hundreds of years later. Eight diagrams reflect objective phenomena with yin and yang symbols. There are different opinions about the original meaning of "two essentials". Some people think that "stubbornness" is also jiao. One refers to sunlight, the other refers to moonlight, and the third refers to the rendezvous (the projection of the rendezvous between the sun and the moon). "Yao" represents yin and yang qi, and divination changes due to the movement of "Yao", so "Yao" is the ancestor of qi. "-"is just Yang, "-"is Yin. The expression of all things evolved from this yin and yang. Some people think that "-"stands for male genitalia and "-"stands for female genitalia. Qian and Guo Moruo hold this view. Six hexagrams can not only refer to the combination of six yin and yang symbols arranged from bottom to top, but also refer to the method of divination by borrowing this combination. The symbol at the bottom is called "Chu Yao" and the symbol at the top is called "Shang Yao", among which, from bottom to top, there are 2345 Yao. Yang Yao'-'(a long horizontal line) is also called' nine', and Yin Yao'-'(two short horizontal lines with a space in the middle) is also called' six'. If the first day is Yang Yao, then the first day can also be called' Nine Days'. If "applying medicine" is yin medicine, then "applying medicine" can also be said to be "still flowing". The first one is added with two or three to form a "stubborn", which is called "inner stubborn" and also called "lower stubborn"; Four or five hexagrams plus six hexagrams form another kind of hexagrams, also called "external hexagrams" and "upper hexagrams". Six-hexagram prediction includes two different methods: Na Jia method and Mei Hua Yi Shu method. Najia combines the six hexagrams with heavenly stems and earthly branches's five elements, the correspondence between six parents and heaven, magic and evil spirits and many other factors, while the number of plum blossoms is relatively simple, mainly based on internal and external hexagrams, body hexagrams, hexagrams changing each other and figures of speech.
