Whether it is a pedestrian bridge or a railway bridge, overpass or viaduct, it will have a negative impact on the surrounding geomantic omen. On the one hand, there is a steady stream of water, people or cars under the bridge, and the bridge itself also has a steady stream of people and cars, which leads to the unstable flow of Feng Shui gas field in a certain range. Therefore, the houses near the bridge are easily hit by the airflow of the bridge, or they are suppressed to commit crimes. The dark evil spirit disturbs the traffic of the house and the geomantic atmosphere of the house itself, causing more or less harm, thus hindering the owner's fortune and family fortune from gradually retreating, which is the old saying that "crossing the bridge is not suitable for people to live in, and it is said that the water will hurt people."
