At the door of a building, can you buy a house, and what about Feng Shui?

What is a doorway? Whether you can provide some pictures is a good judgment. I see. You can't buy such a house. At present, most of our country is in the earthquake zone. From the perspective of support alone, there is no support below and there is no ground traffic support. If a typical' castle in the air' person lives for a long time, it will have an impact on his health and wealth. Please think twice.
