What is the difference between Fuxi's sixty-four hexagrams and Zhouyi's sixty-four hexagrams?

Fuxi has no sixty-four hexagrams, only eight diagrams, and eight diagrams is innate gossip. When I arrived in Zhou Wenwang, I spent eight years in prison. Some people said it was longer, and it changed from gossip to sixty-four hexagrams, and the eight directions also changed. For example, when I moved to the northwest, it was called gossip the day after tomorrow, so nature is the foundation, and the day after tomorrow is the use. Whether it is six hexagrams or feng shui, it is the day after tomorrow.
