Tianzhansha is also called Tianzhansha (the gap between two buildings is facing the residence, which is against Tianzhansha). Feng shui requires that the wind be stored and the energy can be collected, and strong winds are not allowed to rush in and disturb the feng shui aura. As shown in Figure 1, between two buildings that are close to each other, the gap between them creates a narrow tube effect and strengthens the airflow when it passes through. House C faces the gap between A and B, and strong winds directly hit the house, which is a "Tianzhansha (also known as Tianzhansha)". There are two criteria in Feng Shui to determine whether it violates the laws of nature:
1. The gap between the two buildings must be less than 1/8 of the total height. As shown in the figure, Building A is 50 meters high and Building B is 50 meters high. 50 meters, the total height of the two floors is 100 meters, 1/8 is 12.5 meters, a gap exceeding 12.5 meters is not considered a natural disaster, and a gap less than 12.5 meters is a violation of the natural disaster.
2. The distance between house C and the gap must be 0.7 times the total height of the two floors. For example, building A is 50 meters and building B is 50 meters. If C is within the distance of 70 meters, it will not be counted if it exceeds the distance. ?
