“It is believed to restore the flow of “qi” — the life force.”
Done. It’s crap. Any time you hear about Ancient Chinese Medicine talking about “qi” or “balance” or “energy”, just put it into the “crap” column. Same with India and their seven chakras or whatever those things are.
“...It’s just that demon life that’s got you in Feng shui...”
Apologies to the Rolling Stones.
