Feng shui

Feng shui (/ˈfʌŋˌʃuːi/ or /ˌfʌŋˈʃweɪ/), sometimes called Chinese geomancy, is a traditional form of geomancy that originated in ancient China. 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, and in many parts of the contemporary Chinese world, feng shui has been used to determine the orientation of buildings, dwellings, and spiritually significant structures such as tombs.

Feng shui's global uptake during the modern era has been complex. Its host of modern detractors has been very diverse, ranging from 16th-century Jesuit missionaries to the Chinese communist revolutionaries of the 20th century. Regarding its adoption within contemporary Western societies, one scholar writes that "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 Western philosophy of science, feng shui is generally regarded as non-scientific, while some scientific skeptics have more narrowly classified it as a pseudoscience.

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. During the Zhou era, Yingshi was known as Ding and was used, according to the Shijing, to determine the auspicious time for constructing a capital city. The late Yangshao site at Dadiwan (c. 3500–3000 BC) includes a palace-like building (F901) at its center. The building faces south and borders a large plaza. It stands on a north–south axis with another building that apparently housed communal activities. Regional communities may have used the complex.

A grave at Puyang (around 4000 BC) that contains mosaics—a Chinese star map of the Dragon and Tiger asterisms and Beidou (the Big Dipper, Ladle or Bushel)—is oriented along a north–south axis. The presence of both round and square shapes in the Puyang tomb, at Hongshan ceremonial centers and at the late Longshan settlement at Lutaigang, suggests that gaitian cosmography (heaven-round, earth-square) existed in Chinese society long before it appeared in the Zhoubi Suanjing.

Cosmography that bears a resemblance to modern feng shui devices and formulas appears on a piece of jade unearthed at Hanshan and dated around 3000 BC. Archaeologist Li Xueqin links the design to the liuren astrolabe, zhinan zhen and luopan.

Beginning with palatial structures at Erlitou, all capital cities of China followed rules of feng shui for their design and layout. During the Zhou era, the Kaogong ji (Chinese: 考工記; "Manual of Crafts") codified these rules. The carpenter's manual Lu ban jing (魯班經; "Lu ban's manuscript") codified rules for builders. Graves and tombs also followed rules of feng shui from Puyang to Mawangdui and beyond. From the earliest records, the structures of the graves and dwellings seem to have followed the same rules.^{[citation needed]}

Some of the foundations of feng shui go back more than 3,500 years before the invention of the magnetic compass. It originated in Chinese astronomy. Some current techniques can be traced to Neolithic China, while others were added later (most notably the Han dynasty, the Tang, the Song, and the Ming).
