In the layout of geomantic omen, Gengmen refers to three directions: Wu Geng, Gengshen and Geng Xu. These three directions are three evil positions, so be careful not to be washed away.
It should be noted that Feng Shui is not a science, and its authenticity has not been widely recognized, so don't be overly superstitious about Feng Shui. When considering the layout of houses or other places, we should comprehensively consider geographical, environmental, cultural and other factors and adopt scientific and reasonable methods for planning and design.
