Feng Shui, 風水, is the Chinese practice of siting and orienting buildings and graves. The two characters mean wind and water, and they come from one sentence in an old burial text: qi riding the wind disperses, and bounded by water it halts.
So the whole practice is about a current. Gather it, keep it from scattering, and give it somewhere to settle. Everything below is a different method for working out where the settling happens.
It is also the subject in this field with the widest gap between what the sources establish and what gets published in English, so this guide is careful about which is which.
Reading the Land
The older half of the practice reads physical ground. Practitioners call it 巒頭 or 形勢, and the working method is four steps: trace the ridge line carrying the current, examine the hills flanking it, fix the exact spot where it settles, and read the water.
The ideal arrangement has a name for each side, and they are reckoned from inside the site looking out.
- 玄武, the Black Tortoise, is higher ground behind, giving support.
- 朱雀, the Vermilion Bird, is open ground or water in front. It is a vermilion bird rather than a phoenix, despite what some English sources print.
- 青龍, the Azure Dragon, is the ridge on the left.
- 白虎, the White Tiger, is the ridge on the right.
Chinese sources give four animals. Some English ones add a fifth in the centre, and the four animal version is the standard one.
The condition being aimed at is a hill at the back and water in front, forming a sheltered hollow: store the wind, gather the qi. A reader who has seen a well sited old building in southern China will recognise the shape immediately, and it is the part of the practice most people find intuitive.
Reading Direction and Time
The other half, 理氣, works with bearings, trigrams, the five phases, stems and branches, and cycles of time. It needs an instrument, which is the ringed compass called a 羅盤.
Where landform reading asks what the ground is doing, this half asks which way the building is turned and what period it belongs to. The two are not rivals in practice, and most working consultants use both.
The Two School Story Is a Ming Invention
Here is the correction most introductions need.
The division of Feng Shui into a Jiangxi landform lineage and a Fujian compass lineage first appears in a text by a Ming scholar who lived from 1322 to 1373. The figure the Jiangxi line is named for worked in the late Tang and died around 900. So the canonical two school split was written down roughly four hundred and fifty years after the practice it sorts, and about two hundred years after the Song period when Feng Shui was at its most elaborate.
It is a retrospective taxonomy, not a description either group wrote of itself. Academic work agrees the terminology is loose and unstable in the Chinese sources.
There is a further detail which undercuts the binary completely. The official method of the Tang and Song state was neither landform nor compass. It matched the phonetic class of a family surname to permitted directions, and both later approaches displaced it.
One popular explanation deserves to be retired. Jiangxi is mountainous so they read the land, Fujian is flat so they needed a compass. It appears only on commercial sites, and Fujian is one of the most mountainous provinces in China.
San He and San Yuan
These two names come up constantly and are usually explained wrongly. Both are compass systems. Both use a luopan. Neither of them is the landform half.
三合, San He: named for the earthly branch triads it works with, not for landform. It uses four elemental bureaus built from those triads, and a cycle of twelve life stages mapped onto the sectors of the horizon, to judge where water should arrive from and leave. It venerates the Tang figure as its founding patriarch, it combines landform work with formula work, and time is not its primary variable.
三元, San Yuan: established in the Qing, and named for its time cycle doctrine rather than for anything about ground. It splits into the flying star approach and a sixty-four hexagram approach, and time is the organising variable.
The real difference is which formulas, and whether time drives the reading. It is not form against compass.
Two traps worth flagging. 三合 and 三元 each also name a TYPE OF COMPASS, so the school name and the instrument name are the same words. And the list of systems is longer than two: Chinese reference works name several more.
Flying Stars
玄空飛星 assigns nine numbered stars to the nine sectors of a building and tracks how the assignment changes with time.
The nine carry two interchangeable sets of names, one by colour and number and one from the Big Dipper, and each has an element and a home direction: one is water in the north, two earth in the southwest, three wood in the east, four wood in the southeast, five earth in the centre with no trigram at all, six metal in the northwest, seven metal in the west, eight earth in the northeast, nine fire in the south.
The numbers move palace to palace along a fixed path derived from the Luo Shu magic square, the three by three grid whose rows, columns and diagonals each sum to fifteen.
The idea doing the real work is timeliness. A star is favourable when its period is current and unfavourable when it is not, so any source calling a star permanently lucky has flattened the system. Stars eight, nine and one were the timely ones during the last period.
The Periods, and the Date They Turn
Time is divided into nine periods of twenty years, making a cycle of a hundred and eighty years in three groups of sixty. Period eight ran from early February 2004 to early February 2024. Period nine runs from early February 2024 to early February 2044, after which the cycle restarts.
The boundary is Li Chun, the solar term beginning spring, which falls on the third, fourth or fifth of February depending on the year. It is not the first of January and it is not lunar new year, and practitioner sources name both of those as the common error.
Write the ranges as dates rather than as years. Period eight stated as 2004 to 2023 and as 2004 to 2024 are both in circulation, and only the date form is unambiguous. Annual stars turn on the same boundary.
Where Flying Stars Came from, Which Matters More Than It Sounds
This method in its currently taught form is late Qing and Republican rather than ancient, and the history is the single best explanation of why lineages differ.
The Ming and Qing figure credited with reviving it wrote deliberately cryptically, and the method passed on in secret. A practitioner of the next century inherited and interpreted it. Then a scholar working around the turn of the twentieth century obtained a FRAGMENTARY copy of his commentary, worked the method out backwards from it, and published what he had reconstructed. His version became the standard, and most people learning flying stars today are learning it.
So the public method is about a hundred and twenty years old and is one person’s reconstruction of a lineage he was never formally taught. Divergence between lineages is not evidence of bad faith. It is what a secretive transmission produces.
Facing and Sitting, Which Is Contested at Step One
The facing of a building, 向, and its opposite the sitting, 坐, generate the entire chart. Get the facing wrong by one sector and every number in the chart is different.
And practitioners disagree about how to determine it. Three positions are in circulation: the front door, the side receiving the most yang qi, and the most active or brightest or busiest side. Some practitioners state flatly the front door plays no part in classical practice. Others hold the old texts took the reading there.
Sources disagree, this guide does not adjudicate, and apartments are the hardest case of all.
Eight Mansions
八宅 works from the OCCUPANT rather than from the building. A number derived from birth year and sex yields one of eight trigrams, which sorts a person into an east group or a west group, and each group has four favourable and four unfavourable directions.
- 生氣, generating qi: vitality, drive and advancement. Usually rated the strongest.
- 天醫, the heavenly doctor: health, recovery and steady support.
- 延年, extending years: longevity and relationships.
- 伏位, the crouching position: the person’s own direction, mild and settling.
- 絕命, severed fate: the worst of the four difficult ones.
- 五鬼, five ghosts: quarrels, theft and betrayal.
- 六煞, six killings: entanglement and disputes.
- 禍害, misfortune and harm: the mildest, friction and small setbacks.
And the Gua Number Has Its Own Disputes
The number is arrived at by arithmetic on the birth year, with different formulas for men and women, and several parts of it are unsettled.
The sharpest for a reader is the year boundary. Some consultants take the year from Li Chun in early February and some from lunar new year, which lands anywhere from late January to the middle of February. Anybody born between the start of January and the middle of February is therefore liable to be assigned two different numbers, two different groups, and two entirely different sets of favourable directions depending on who they ask.
There are three more. The constant used in the women’s formula varies between sources. The adjustment for births from 2000 onwards is stated cleanly for women and not for men. And the number five has no trigram, so it is reassigned: the majority convention sends a man to one trigram and a woman to another, a minority convention reverses it, and some systems decline to use five at all. Because both replacements sit in the same group, the dispute changes all eight direction assignments while leaving the east or west grouping alone.
If your birthday falls in January or early February, ask which boundary a consultant uses. It decides the whole answer.
The Twenty-Four Mountains, and Why Eight Degrees Matters
The horizon is divided into twenty-four named sectors of fifteen degrees each. They are made of twelve earthly branches, eight heavenly stems and four trigrams. The two remaining stems are left out because they belong to the centre and have no direction, and only the four corner trigrams appear, because the cardinal positions are taken by branches.
Inside each trigram’s forty-five degrees the three sectors are ranked in tiers, and the tier is what decides whether the stars in a chart fly forward or in reverse.
Now the consequence. A bearing error of about eight degrees moves a reading into the neighbouring sector, changing the tier, possibly the polarity, and therefore the entire chart. A fifteen degree error changes it outright. This is a practice where the instrument reading is load bearing.
The Compass, and the Three Needles
A luopan is a rotating dial carrying up to about forty concentric rings of formulas, seated in a square base, with a magnetic needle at the centre and a red thread crossing the dial as the reading line.
One piece of prehistory is worth knowing. The markings on a Chinese divination board from the third century BCE and the markings on the first magnetic compasses are close to identical, so the luopan’s ring layout descends from a divination instrument rather than from a navigational one.
The detail catching most readers by surprise is the needles. A San He compass carries THREE full rings of twenty-four sectors, each with a job of its own and each offset from the baseline by seven and a half degrees, which is half a sector.
- The earth plate ring establishes the sitting and facing of the building. It is the baseline everything else refers to.
- The human plate ring assesses the surrounding hills and structures.
- The heaven plate ring judges incoming and outgoing water.
So reading the same building off a different ring gives a different bearing, and the offset is large enough to move a sector. Traditional accounts attribute the extra needles to two named historical figures, and the practitioner source reporting those accounts adds its own caveat: the old books do not say so, and these are later developments passed on by word of mouth.
Magnetic North, or True North
Magnetic declination is the angle between the magnetic north a needle finds and geographic north, and it varies by place and drifts year to year.
One position holds Feng Shui uses magnetic bearings with no correction, because the luopan was always a magnetic instrument and the sectors were laid out against it. The other holds the reading should be corrected to true north. Both are stated flatly as fact by practitioners, and research found no academic adjudication.
The size of it is the point. In parts of North America declination exceeds fifteen degrees, which is more than a whole sector, so this single methodological choice hands two consultants different charts for the same house. Steel framing, rebar and electrical equipment deflect the needle as well, which is why careful practitioners take readings outside, at several distances, and average them.
Date Selection
擇日 picks an auspicious day and hour for breaking ground, moving in or burying, by matching yin and yang, the five phases and the stem and branch of the moment against the symbolic spirits governing it.
Several systems exist, built respectively on the seven luminaries, on Qi Men Dun Jia, on other divination systems, and on named popular traditions. A Qianlong era imperial compendium consolidated the competing traditions into one practical synthesis, and annual almanacs print each day’s suitable and unsuitable activities.
The systems contradicting one another is documented rather than alleged. A Chinese reference work states the transmitted schools are beyond counting, they contradict each other, and even within one school views diverge. Different editions of the almanac sometimes print opposite verdicts for the same day.
And the classical statement of the problem is better than any modern one. An old polemical passage asks whether a given day is suitable for taking a wife, and answers it four times: the five elements school says yes, the geomancy school says no, one calendar school says inauspicious, another says gravely inauspicious. Four experts, one date, four verdicts.
Western Adaptations
A method widely taught in the West overlays a three by three grid of life areas on a floor plan, ALIGNED TO THE FRONT DOOR, so the door wall is always the bottom row and the grid turns with the entrance rather than with the compass. It needs no luopan and takes no bearing at all.
The consequence is structural: the same physical room is a different life area under this method than under any compass system. It reached English readers through a 1983 book written with the teacher who taught it.
On how to weigh it, two things are worth saying plainly, and they are both about sources rather than about merit.
- Every biographical claim about the teacher who brought this method west comes from the organisation he founded, including his academic appointments and his lineage. Research located no independent documentation of recognition by any Tibetan authority.
- Every hostile characterisation of the method comes from classical practitioners who compete with it commercially.
What the tradition says about itself is the fairest ground here, and it is not a criticism. Its own framing describes it as a later stage of a Buddhist transmission, deliberately made easy for Western audiences. It does not claim to be classical compass Feng Shui, so a reader comparing the two is comparing different things rather than a real and a fake.
What Is Classical, and What Is Retail
Plenty of what is sold as Feng Shui has a documented basis, and plenty has none located.
The element logic is classical. Two of the unfavourable stars are earth, earth is drained by metal, so metal is used against them and fire avoided near them. So is the instruction to leave an afflicted sector alone, undug, undrilled and unrenovated, which predates the object industry entirely. And the landform judgements are classical: support behind, an open forecourt, avoiding a site with a road aimed straight at it.
The wealth corner is the cleanest counter-example. As a fixed cell of every floor plan it belongs to the Western grid method of the 1980s. Classical systems locate wealth through the facing star for the current period, which is specific to one building and expires with the period rather than living permanently in one corner of a room.
For the named objects, the three legged toad, the crystal grids, the salt water cures, the six rod wind chimes and the annual cure kits, research located no classical text prescribing any of them. They are product implementations of the element rule, sold as though the object were the doctrine. And nearly all popular English writing on this subject is produced by somebody selling a consultation, a course or an object, which is worth holding in mind while reading any of it.
The Old Attributions, and Who Doubted Them First
This is the best historical point available, and it is not Western revisionism.
The burial text the whole tradition quotes has been attributed to a fourth century scholar since the Song. The Qing imperial editors who catalogued it put three objections in the catalogue itself. His own biography records the books he received and never mentions writing this one. Late Tang bibliographies list burial texts with no author’s name on them. And the Song bibliography is the first to record one under his. The surviving text is also a Song and Yuan edit of something larger.
The editors are blunter still about the figure the Jiangxi line is named for. He appears in no standard history. The Song bibliography knows him only by a nickname. And the famous story of his fleeing a rebellion with secret palace texts is dismissed in their catalogue as baseless talk not meriting belief.
The bibliographers of imperial China were the sharpest critics this tradition has had. A modern practitioner repeating the founding legends is not being dishonest, and they are repeating something the Chinese state’s own librarians rejected in the 1780s.
And Where the Transmission Ran
After 1949 the practice was officially treated as superstition on the mainland, and during the Cultural Revolution it was among the old things targeted for destruction, with practitioners attacked and their books burned. It remains unlawful to register a Feng Shui consultancy as a business in mainland China, and advertising the practice is banned.
So the continuous professional transmission through the twentieth century ran largely through Hong Kong, Taiwan, Malaysia and Singapore, and the present commercial and scientific framing of the subject dates from the revivals of the 1980s onwards rather than from an unbroken line.
Why Two Practitioners Assess the Same House Differently
Every reason here is technical, and together they explain almost all of it.
- Different system entirely. Eight Mansions keys to the occupant’s birth year, Flying Stars to the building’s period and bearing, San He to landform and water, and the Western grid method to the front door with no bearing at all.
- Eight Mansions and Flying Stars routinely disagree about one room. A room might be a person’s worst direction while carrying the timely star pair, and nothing inside either system resolves the clash.
- Different facing determination, which regenerates every number in the chart.
- Different compass reading: declination applied or not, steel deflection, and which of three rings seven and a half degrees apart the bearing came from.
- A different period for the building, taken from construction, from moving in, or from a major renovation. Two adjacent periods share no numbers, and the usual fallback is to build both charts and compare.
- A bearing straddling a sector edge, where one practitioner uses the standard chart and another a replacement one, with lineages differing on both the threshold and the table.
- A different date selection system, which the classical literature already documents as contradictory.
- Whether the occupant’s own birth chart is factored in at all.
- The Gua number disputes, which reach anybody born in January or early February.
- And underneath all of it, a transmission history which was fragmentary by design.
The birth chart half of the list is a subject of its own, and it is in what is BaZi? a guide to the Four Pillars of Destiny.
Before Booking
Three questions sort a trained consultant from somebody selling ornaments. Which system do you work in? How do you determine the facing of a building? And which period do you assign a house, and from what date?
A fourth is worth adding if your birthday falls near the start of February: which year boundary do you use for a Gua number?
None of those is a challenge. They are the questions whose answers change the advice, and a practitioner with a defined method will enjoy being asked.
What a clear answer sounds like, and what a weak one sounds like, is set out in how to tell a careful practitioner from a confident one.
