From the perspective of geomantic omen, indoor plants used for geomantic omen can be roughly divided into two types, one is evergreen plants that play the role of "flourishing qi" and the other is cactus plants that are used to ward off evil spirits. These two plants have opposite effects, so they are placed in different positions. If you are confused, it will not only help, but will be self-defeating and bring harm. Now I'll tell you the mystery. You must keep in mind the following main principles: put evergreen plants with large leaves in the "prosperous position" and cactus thorns in the "declining position" As long as you can grasp the above essentials, you will not be confused by good luck! As for those common directions that are not prosperous, generally speaking, it doesn't matter what plants are planted (but it is best not to put "evil" spikes).
