The most important thing is to embrace mountains and rivers. The mountain ring can gather the field energy of the sun, the moon and the stars (like a satellite receiving antenna shaped like a pot cover), and the water hug is also surrounded by water to gather the field energy (the so-called "gas dispersed with the wind, the boundary water stops"). In other words, the five-element field of the sun, the moon and the stars can gather water along the mountains. The so-called cave center is the focus of the five-element field, but the surrounding landscape can't be as regular as the satellite signal receiver, so it is not so easy to find its focus.
The only sign of the heart of the cave (the only sign of the land of Feng Shui): Because the soil that has been focused on this focus for many years will produce obvious color changes, it is impossible for any living animal to survive in this focus, and even the roots of plants can't exist (even if there are, they are already burnt), let alone any other treasures. This is the real acupoint.
Yin Zhai decides fate, while Yang Zhai reflects fate. Yin Zhai accounted for seven points, Yang Zhai three points. What is a person's fate? The eight characters were set when he was born.
