The spine corresponds to the orientation of the house.

In geomantic omen, the spine is an important part of the human body and plays an important role. According to the traditional geomantic omen theory, the spine corresponds to the orientation of the villa, that is, the orientation of the spine when people sit facing south. In Yang Zhai geomantic omen, the north-south direction is considered as the most auspicious direction, because the north-south direction is the dividing line between Tai Chi and Tai Chi, which has the characteristics of balance and harmony between Yin and Yang. Therefore, if you want to arrange the room where the spine is located in the villa, you can consider choosing the north-south room to achieve better feng shui effect.
