What do the six hexagrams of the Book of Changes mean?

Six hexagrams is just a tool, and it is a method of the evolution of hexagrams. To understand six hexagrams, we must first understand gossip. Six hexagons are divided into upper hexagons and lower hexagons. The upper hexagrams are 1, 2 and 3, and the lower hexagrams are 4, 5 and 6. The above hexagrams are all yang, which is the work of gossip, and the following hexagrams are all yin and Kun. The other six hexagrams are all evolved from hanging up and down. The first one is the lowest one, that is, from bottom to top, the first one is at the bottom, the second one is at the top, and so on, and the sixth one is at the top. Six hexagrams are the methods and means to evolve the changes of everything in the world, and they are the foundation. A hanging must be six hexagrams, and each name is three hexagrams, but it does not mean that a hanging is composed of two pseudonyms. The combination of hexagrams is varied, and the deeper you understand it, the more random the combination method will be.
