Divination problem

Positive position and negative position (also called improper position)

Position inversion refers to the position of the Yijing hexagrams, which consists of two eight-classics hexagrams (each eight-classics hexagrams consists of three hexagrams). The above is the content of divination in the Book of Changes.

For the convenience of reading, the ancients called Yang Yao nine X (X is one to six) and Yin Yao six X(X is also one to six).

The ancients believed that the first, third and fifth of the six hexagrams should be yang hexagrams. The second, fourth and sixth hexagram should be yin hexagram. When the first, third and fifth are all positive, then we say it is positive. On the contrary, when the first hexagram is negative, it is inverted, because the first hexagram should be positive. Similarly, when two, four and six are positive hexagrams, they are also inverted hexagrams, because two, four and six were negative hexagrams, and now.
