How do people who belong to the five elements buy a house on the fifth floor to adjust the feng shui?

There are five behaviors in the fifth floor soil, and you belong to the five elements of water, which is not conducive to water. Metal products can be placed in the north (in different directions) and a little west, and white or silver is the best. It is also good to put a safe in the northwest, which can increase wealth and be good for health. The baby belongs to the dragon and the five elements belong to the earth, so it is just right to live on the fifth floor.
