What kind of screen is best to use between kitchen and toilet in geomantic omen?

It's better to use patterns with five elements of earth (such as the Great Wall or hillside), because the fire in the kitchen is heavy, and the atmosphere of fire is vented with earth, which is beneficial to the liver health of the owner. Then the bathroom belongs to water, but the water in the bathroom belongs to sewage, so using the principle of soil water is beneficial to the kidney health of the male owner.
