What does "Nine Planetary Peaks" mean in Feng Shui?

The peaks in nature are divided into five shapes: gold, wood, water, fire and earth. In fact, the characteristics of peaks can be divided into five shapes. Because there are many versions of the nine planets' theory of feng shui and regulating qi, the theory of Lu 'an's head and five stars is subdivided into nine planets, which evolved from nine shape features to the peak of auspicious nine planets and fierce nine planets, and finally, like the Tang Priest in The Journey to the West's 81 Difficult Project, it evolved into 998 1 peak variant shape. There should be more books of this kind, with graphics, but the description of concepts and shapes is inaccurate, difficult to master and confusing.
