Origins 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 (; "Manual of Crafts") codified these rules. The carpenter's manual
Lu ban jing (; "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.
Early instruments and techniques at
Chinatown station (Los Angeles Metro) 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). The astronomical history of feng shui is evident in the development of instruments and techniques. According to the
Zhouli, the original feng shui instrument may have been a
gnomon. Chinese used circumpolar stars to determine the north–south axis of settlements. This technique explains why Shang palaces at
Xiaotun lie 10° east of due north. In some of the cases, as
Paul Wheatley observed, they bisected the angle between the directions of the rising and setting sun to find north. This technique provided the more precise alignments of the Shang walls at
Yanshi and
Zhengzhou. Rituals for using a feng shui instrument required a diviner to examine current sky phenomena to set the device and adjust their position in relation to the device. The oldest examples of instruments used for feng shui are
liuren astrolabes, also known as
shi. These consist of a
lacquered, two-sided board with astronomical sightlines. The earliest examples of liuren astrolabes have been unearthed from tombs that date between 278 BC and 209 BC. Along with divination for
Da Liu Ren the boards were commonly used to chart the motion of
Taiyi (Pole star) through the nine palaces. The markings on a
liuren/shi and the first magnetic compasses are virtually identical. The
magnetic compass was used for feng shui since its invention. Traditional feng shui instrumentation consists of the
luopan or the earlier south-pointing spoon (
zhinan zhen)—though a conventional compass could suffice if one understood the differences. Not to be confused with the
South-pointing chariot which was used for navigation. A feng shui ruler (a later invention) may also be employed.
Imperial court usage From at least the
Han dynasty, feng shui was formally integrated into Chinese imperial governance, with court officials conducting geomantic assessments for the siting of palaces, capital cities, and imperial tombs. The practice reached its institutional peak during the
Ming (1368–1644) and
Qing (1644–1912) dynasties, when the
Qintianjian (欽天監, Imperial Astronomical Bureau) employed specialists in feng shui alongside astronomers and calendar-makers. Major imperial projects including the
Forbidden City and the
Ming tombs were designed in accordance with feng shui principles, with the Forbidden City's north–south axial alignment and the placement of the artificial hill of
Jingshan to its north reflecting classical geomantic conventions. The imperial court's control over geomantic knowledge served both practical and political functions, as the proper siting of state structures was understood as a demonstration of the ruling dynasty's claim to the
Mandate of Heaven.
Later history After the Song dynasty, divination began to decline as a political institution and instead became an increasingly private affair. Many feng shui experts and diviners sold their services to the public market, allowing feng shui to quickly grow in popularity. Under China's
Century of Humiliation, feng shui began to receive implicit government encouragement as a method of colonial resistance. Through the militarization of the countryside, the local gentry used feng shui to justify and promote popular attacks against missionaries and colonial infrastructure. This allowed local elites and government officials to bypass foreign
extraterritoriality and maintain local sovereignty. This, in addition to the cultural aspects of feng shui, made the practice a powerful expression of demarcation between foreign and Chinese identities. It was only after China's
reform and opening up that feng shui would see a complete resurgence. As economic liberalization promoted social competition and individualism, feng shui was able to find new footing due to its focus on individualism and amoral justification of social differences. ==Foundational concepts==
