In geomantic omen, corner-filling cards are considered to fill the earth's atmosphere and make the land type meet the requirements of a round place. Choose sunny days when placing corner filling cards, and pay attention to the stone. The corner filling position should not be too high, nor should it be placed in the corner or under the cabinet. It is best to put it in a bright place.
It should be noted that the above suggestions are for reference only, and the specific placement method needs to be determined according to the actual situation and personal needs.
