Bagua Luo board convex mirror back : Yonkami-juu specification [ golden / large size ] | feng shui entrance mirror Goods

how do i set this up .. do i put this inside apartment.with the mirror facing out side, i dont live in a house. i live on the 5th floor of an apt.

Can i place it on my door. my house entry door is very tall. i am trying to use it to block negative energy coming from house opposite to me.

Do you have the size? Or the diameter?

There's no spot available above the front door, is it okay to place it near my window (on the vinyl siding)? Can I put a few, each facing a direction?
