1. The door facing east makes family life beautiful. 2. If the house is located in a low-lying place, the foundation of the house is lower than the surrounding terrain. This terrain is not conducive to ventilation, lighting, drainage, etc. And it is not conducive to people's daily life. What's more, due to the low terrain, the turbid air with relatively high density around the basin will be concentrated in low-lying areas, which is not conducive to people's health. From the perspective of geomantic omen, all low-lying places gather yin, with more yin and less yang. This is a very bad geomantic omen phenomenon, which not only affects people's health, but also affects people's luck and career. So the low-lying feng shui in front of the east gate is not good. Solemnly declare: the answer is for reference only, don't be blindly superstitious.
