Geomantic omen talks about heightening old buildings, okay? -1. It is necessary to confirm whether the original foundation is solid and reliable with bearing capacity. 2. It must be confirmed whether the wall has bearing capacity. These two points involve structural mechanics, but Feng Shui does not.
Geomantic omen and housing emphasize one-stop, one-stop, one-stop, and avoid patchwork. It can only be said that repairing layer by layer is better than patchwork. Of course, it is best to take shape at one time and build a house at one time.
