The difference between master divination and changing divination into divination.

The difference between the main divination and the change of divination is that the four divinations change, and the yin divination changes into the yang divination. In this case, it was the wind that made the hexagrams dirty, that is, the four hexagrams changed, the yin became the yang, the upper hexagram became the upper hexagram, and the lower hexagram became the heavier hexagram, indicating that things were developing well and the upper hexagram was compared.
