I think Fend Shui is very interesting but some tips are just common sense (like a tidy space, a few furnitures). Fend Shui use the combination of four elements: fire, water, wood and metal. If we have a good combination of this elements we'll have a relaxing, peacefull and equilibrate place. We can equilibrate the energy (ying and yang) whit a combination of diferents colors, elements, and trying to put the element in the correct place (north, south, east and west)
I know people who like to use Fend Shui at home and at the office, also I know courses about it (I'm trying my family give me one, meanwhile I read books)
