The Ten Books of the Sun Family in the Qing Dynasty pointed out: "People are mainly suitable for living in mountains and rivers, with the greatest momentum and the most important relationship with people's fortunes." Feng shui pays attention to mountain topography. Long Mai's shape and potential are different, thousands of feet is potential, potential is prospect, and shape is close-up. Potential is the worship of form, and form is the product of potential. So the potential is tangible, and the tangible awareness of the potential exists outside, while the shape exists inside. It looks like a wall and a balcony. The potential is a set of ups and downs, shaped like an isolated mountain. It is easy to recognize the situation and observe the pattern. The situation is cause and effect. If it is Ma Benteng, if it is flowing, I want it to be big and strong, different but specialized and smooth. Modeling should be thick, gas storage, gas storage. Moderate feng shui is just right, impartial, neither too big nor too small, neither too high nor too low, as optimized as possible and close to perfection. On the point cloud in Guan Shi's Geography refers to Meng: I want it to be high but not dangerous, low but not empty, obvious but not revealing, quiet but not choking, strange but not strange, clever but not bad.
