What are the benefits of putting stones in the bedroom or study for geomantic omen?

In geomantic omen, especially in houses in modern cities, wooden floors and many wooden furniture are popular in bedrooms, so bedrooms belong to wood in the five elements. The wood property of the study is more prominent because the raw materials of the paper in the book come from wood pulp, so it belongs to wood. If a person is born with strong wood, or strong gold and strong soil, and moves between the study and the bedroom for a long time, it will either make his own wood more exciting, or it will collide or interfere with his own five elements, then he will lose a way to balance the five elements. The bedroom or study itself is extremely woody and has lost the balance of the five elements. In order to restrain wood, stones are placed in it, which belong to gold and Jin Kemu in the five elements, so as to eliminate the adverse effects of being too strong.
