Hello,
I think that the principles of Feng Shui are interesting there are very things that make us uncomfortable in a place.
And it’s important to study about it, and figher out what can we change to feel better, to have good energy.
I don’t know anyone who tried it or believes in it, but I never talk about it, probably some of my friends believed but never told me.
I don’t know of any buildings or places were I leave that are designed by those principles.
