Feng shui theory: where should the family sword be placed?

hanging (or placing) sharp weapons such as swords generally follows a principle: the front and the tip should not point in the wrong direction, but generally point to the ground. Sheath should also be put on to avoid sharp weapons such as sharp swords with sharp edges

. Generally, you can't hang them casually, which may ruin your own geomantic omen and hurt the surrounding geomantic omen

If it's not very urgent, try to hide it.
