Excuse me, 200 meters behind the house is a 33-story building. Can it be regarded as a backer?

Hello, your description is vague, you don't know the location, you don't know the layout of your house, and you don't know what other buildings, roads and rivers are within 200 meters. So there's no way to tell if it's a backer.

But the essence of geomantic omen is environmental planning, architectural layout and behavioral psychology. It's no big deal to have a backer, not to mention forcibly pulling geomantic omen, so it's good to be down-to-earth and feel comfortable.

Hope to adopt, thank you.
