Feng shui (ˈfʌŋˌʃuːi ), sometimes called Chinese geomancy, is an ancient Chinese traditional practice which claims to use energy forces to harmonize individuals with their surrounding environment. The term feng shui means, literally, "wind-water" (i.e. fluid). From ancient times, landscapes and bodies of water were thought to direct the flow of the universal Qi – "cosmic current" or energy – through places and structures. More broadly, feng shui includes astronomical, astrological, architectural, cosmological, geographical and topographical dimensions.
Historically, as well as in many parts of the contemporary Chinese world, feng shui was used to orient buildings and spiritually significant structures such as tombs, as well as dwellings and other structures. One scholar writes that in contemporary Western societies, however, "feng shui tends to be reduced to interior design for health and wealth. It has become increasingly visible through 'feng shui consultants' and corporate architects who charge large sums of money for their analysis, advice and design." In the wake of the climate crisis, feng shui is being taken into academic consideration for possible contributions to ecological philosophy.
The concept of Qi and other vital energy formulations is pseudoscientific, and feng shui has been described as a paradigmatic example of pseudoscience. However, some academics regard modern practice of feng shui as a non-scientific cultural tradition rather than a pseudoscientific discipline, noting its functional usage as a tool for rural development, social mobilization, and conflict resolution.
The Yangshao and Hongshan cultures provide the earliest known evidence for the use of feng shui. Until the invention of the magnetic compass, feng shui relied on astronomy to find correlations between humans and the universe.
In 4000 BC, the doors of dwellings in Banpo were aligned with the asterism Yingshi just after the winter solstice—this sited the homes for solar gain.
