Which ancient books of the Book of Changes have seen the theory of "homology of water and soil"?

There are not only fire-soil homology and water-soil homology in the five elements, but also both of them are correct and only derived from two mathematical models. We need to know where his theoretical system came from after Guiguzi Lukele's Tiism appeared. It can be traced back to the period of the ancient Yellow Emperor, and their mathematical model system is: five movements and six qi, and six hexagrams of Najia, Na Zhi and Yinna. Soil and water belong to the same origin, and the infinite soil belongs to Li Kan. A palace of water and soil, a palace of fire and soil, is the root of fire and soil, and water and soil are the same palace. Li Kan is originally expensive water, and it is also a dry Kun, a body, and a six-year-old. So in that house, Gan Kun was used instead of Li Kan, Na Ren, Guihe, A and B. The so-called "Gui Ren matches A and B, and Gan Kun covers all of them".

From all kinds of data, the two theories existed at the same time, but before the Song Dynasty, it was obvious that the integration of water and soil was the mainstream, and after the Song Dynasty, especially in the Ming Dynasty, the integration of water, fire and soil became the mainstream. This is because after the Song Dynasty, Ziping theory began to occupy the mainstream of Lu's life, while the ancient law gradually disappeared, so it can be said that with the prevalence of Ziping's eight-character theory, the theory of fire, water and soil became the mainstream. The biggest difference between Ziping's method and the ancient method is that it shifted from focusing on the annual column to the solar column. Because of this change, the technique of numerology has also changed: the ancient method is based on the annual column, and the three lives are based on the nectar. The hierarchical transformation is mainly based on Rizhu, which has three elements: Ganlu, life support and underground support. Why is there such a change in technology? Let's go back to the difference between the two five elements, that is, the true five acts as the innate invisible qi and the ten acts as the tangible five elements. Congenital yang, acquired yin. The innate five elements are divided into yin and yang, and the acquired five elements are divided into yin and yang. It is difficult to directly observe the invisible qi.
