What is the separation of heaven and earth?

There is "heaven and earth denial" in the sixty-four hexagrams of the Book of Changes, but there is no "heaven and earth separation", which should be "mountain separation". Mountain peeling is a "peeling" divination.

One hexagram has six hexagrams, and when the hexagram is peeled off, the hexagram is on the top, the hexagram is on the bottom, the hexagram is on the mountain, and the hexagram is on the ground, which is collectively called "mountain peeling". The hexagram of undressing is: undressing is not good for you. Warning people not to act blindly. Stripping hexagrams is a villain stripping a gentleman hexagrams. It can be obtained by divination or lottery, so be extra careful what you say or do.
