Look at your own two-story building from the perspective of geomantic omen and design a semi-basement, okay? I hope someone can give me some advice!
If there are two floors, the original feng shui pattern will change. The first floor is a static house, and the second to fifth floors are mobile houses. Different viewpoints lead to different analysis angles. If the original simple house pattern is right, adding a basement will change the position of the original Feng Shui star. Therefore, it is not recommended to make a basement easily.
