Why six hexagrams? Isn't it Liu Yao?

Don't think that seeing a hexagram with six hexagrams is called sixty-four hexagrams instead of gossip. Sixty-four hexagrams are divided into eight palaces, and the first hexagram in each palace is gossip. Sixty-four hexagrams also evolved from gossip. . In addition, what most people say about six hexagrams refers to "six hexagrams prediction", which is a kind of divination. Generally speaking, the six hexagrams generally refer to this divination method. )
