What Feng Shui should a man who is a Dragon and a woman who is a Tiger pay attention to when buying a house?

The dragon's five elements belong to earth, the tiger's five elements belong to wood, and wood controls earth. You can buy a floor that belongs to fire, or decorate it with red or purple colors. In this way, wood generates fire and vents wood energy, and fire generates earth and becomes prosperous. If the wood is weak and the earth is strong, the wood cannot conquer the earth, but the earth can be peaceful. Choose the last two and seven floors that belong to fire. Years of strong fire are beneficial to these floors (i.e., the years of snake and horse).
