Anti-bow way and anti-bow evil

"Anti-bow evil spirit" means that there is an arc in front of the house to arch outward. For example, "anti-bow water"-the river in front of the house is anti-bow. Another example is the "anti-bow road"-the road is curved, and the door is facing this road. Another example is the "anti-arch building"-a circular building, such as a large supermarket and a large stadium, where nearby houses will be reflected by a circular body. It is one of the biggest shortcomings in geomantic omen.
