Can you put horns at home?

Horn is pointed, which belongs to the shape of fire in geomantic omen. In geomantic omen, there is a saying that Jin Mu's soil and water don't need fire, so it is generally not suitable to place it at home. However, a clever geomantic omen can use fire-shaped things to promote Mars to achieve the purpose of urging officials to promote wealth and Cui Ding. However, there are strict requirements on the method and orientation of placing, so don't place it randomly.
