In Feng Shui treasure land, living on the "highlands" and living in the "basin" seem to be contradictory

Highland is a microscopic view, and basin is a macroscopic view. From a large perspective, it is required that the northwest and east are surrounded by mountains on three sides, and the south faces a river (or lake). Feng shui comes from the south. Because it is hindered by the mountains, it is accumulated in this small basin, and the feng shui is good. From a small perspective, it is better to require a higher terrain, because if the terrain is low, it is easy to accumulate water and spoil the feng shui.
