From the point of view of room space design, the decoration of running water fountain can not destroy the feng shui of the room. Don't put the fountain behind the sofa. From the perspective of geomantic omen, water is impermanent, relying on water as a backing is unreliable and difficult to stabilize, thus affecting the stability of housing fortune. If you put running water next to the sofa, it will not cause great obstacles to housing traffic and geomantic omen. At the same time, running water can't collide with the stove, because fire and water are incompatible, so if running water in the living room collides with the stove, Feng Shui thinks it will affect the health of family members. The height of running water should not be too high, and the horizontal position should not be higher than the height of the average person's heart. From the perspective of Chinese medicine, there is water in the fish tank, and people's hearts belong to fire. Water is not good for people. The position should not be lower than people's knees, forming treading water. If water doesn't flow, it will flush money. Even from the perspective of viewing, too high or too low is not conducive to people's viewing, while from the perspective of safety, too high and unstable is not good for family members, especially children. In addition, the circulating water of the running water fountain should flow into the house, not outward, so as to avoid the loss of wealth.
