Xuan Kong Feng Shui ( aka "Flying Stars Wind Water" )

This School of Xuan Kong Feng Shui system rests on the astronomical basis of the "flight patterns of dynamic stars" through the three yuans or eras of nine yuns or periods which holds seriously impactful consequences on the occupants who lived within a confined space walled by at least three sides and a roof over it. The most common interpretation of this criteria is the human residence or shop space that satisfies this prognosis.

Modern research are still being conducted into the extent of its potency and pervasiveness on the occupant's well-being at a chosen "confined space" in one location over a correspondingly similar conditions in another location can result in a wide rift in terms of favourable versus unfavourable outcome or degree of luckiness benefiting or affecting the individuals living therein.

Though this is a deep and very profound knowledge of Feng Shui studies which most experienced Feng Shui practitioners and scholars alike accepted its pervasiveness but still the debate is endless on the "quantification of its potency" which ranges widely and also depend on which Feng Shui practitioners and their level of experience and skill-sets, are conducting and administrating the "commissioning of the flight patterns of the dynamic stars configuration".
