The schools of feng shui
The Form school: read the ground
The older systematic branch is credited to Yang Yunsong (楊筠松), an imperial official of the late Tang. Its method is observational. You trace a mountain range as a dragon (龍), a line of moving energy running through the terrain. You look at the lesser hills flanking it, the sand (砂). You read where water gathers and where it drains. And you locate the spot (穴), the precise point where all of it comes together favorably.
Its most portable idea is the arrangement of four positions around a site: solid ground rising behind, open space in front, and protective flanks on either side, named for the black tortoise, vermilion bird, azure dragon, and white tiger. That template is what our commanding position page describes after it has been shrunk from a valley to a bedroom. A wall behind the headboard is a backing mountain. The clear floor in front of a desk is a bright hall.
The Compass school: read the bearing
The calculating branch took shape later, during the Song, and works from an instrument rather than a view. The luopan carries concentric rings of trigrams, stems and branches, and directional divisions, and the practitioner derives results by computation.
A common explanation for why this branch arose is terrain. Form school method needs landform to read, and much of northern and eastern China is flat. Where there is no dragon to trace, a system based on orientation and cycles gives you something to work with. Treat that as the usual account rather than a settled historical finding, but it does explain a lot about where each branch took hold.
Compass school is a container, not a single method. Inside it sit Eight Mansions, which assigns people and houses trigram types, and Xuan Kong Flying Star, which charts a building by construction period and facing and adds a layer that changes every year. San He and San Yuan are two further families within it. These systems can and do rate the same house differently.
Which comes first
Practitioners who work with both branches usually put form ahead of compass, summarized in a maxim repeated throughout Chinese feng shui literature: form is the substance, compass is the function (巒頭為體，理氣為用). The reasoning is that a favorable bearing cannot rescue a site that is exposed, cramped, or sitting where water rushes past it.
The domestic version of that priority runs through this whole site. Place the bed against a solid wall with the door in view first. Only then, if the room still allows it, point the headboard toward one of your kua directions. When the two conflict, the tradition sides with placement.
Where BTB fits, and why American advice reads the way it does
Black Sect Tantric Buddhism feng shui arrived in the United States with Lin Yun in the 1980s. It discards the compass. The bagua is aligned to the wall containing your front door, so the wealth corner is always the far left of the plan as you look in, no bearing required.
That decision made the practice teachable to people without a luopan, and it is why most English-language books, magazine pieces, and décor articles are BTB whether or not they say so. It is also why so much of that writing conflicts with anything written from a classical compass position. Both can be reported accurately. What cannot be done honestly is mixing them in one paragraph, which is exactly what most listicles do.
| Term | Pinyin | Chinese | Meaning |
|---|---|---|---|
| Form school | Xíngshì pài | 形勢派 | The landscape-reading branch. Also called Luantou pai (巒頭派) or the Jiangxi school. |
| Compass school | Lǐqì pài | 理氣派 | The calculating branch, working from direction and time. Also called the Fujian school. |
| Luopan | luópán | 羅盤 | The multi-ring feng shui compass, the Compass school's instrument. |
| Dragon | lóng | 龍 | A mountain range read as a line of moving energy. Tracing it is the Form school's central skill. |
| The spot | xué | 穴 | The precise point where a site is placed, the goal of a Form school reading. |
| Backing mountain | kàoshān | 靠山 | Solid support behind a site. Scaled down, it becomes the wall behind your headboard. |
How to use this when advice conflicts
Ask which system a rule comes from before deciding it is wrong. Three quick tests cover most cases. If a page locates your wealth corner without asking which way the building faces, it is BTB. If it asks for your birth year, it is Eight Mansions. If it asks when the building was built, it is Flying Star.
Once you can name the source, contradictory advice stops being noise. You are not looking at a field that cannot agree with itself so much as at several methods with different inputs, published without labels. Our practice is to attach the label, which is set out on the methodology page, and to leave genuine disputes visible rather than resolve them quietly.
Frequently asked questions
What is the difference between the Form school and the Compass school?
The Form school reads the physical landscape: the shape of hills, the course of water, what stands behind a site and what opens in front of it. The Compass school reads direction and time, using the luopan compass, the trigrams, and calculations such as Eight Mansions and Flying Star. One looks out the window, the other looks at an instrument.
Which school is the original one?
The Form school is older as a systematic method. Yang Yunsong, an imperial official of the late Tang dynasty, is traditionally credited with organizing it, and it is often called the Jiangxi school after the region associated with his lineage. The Compass school took shape later, during the Song dynasty, and is often called the Fujian school.
Which school should I follow?
Most practitioners use both, and the traditional order of priority is that form comes first. A widely repeated practitioner maxim puts it as form is the substance and compass is the function: no amount of favorable direction is thought to rescue a badly shaped site. For a reader at home, that means placement and surroundings matter before compass bearings do.
Where does the Black Sect (BTB) school fit?
Outside both. Black Sect Tantric Buddhism feng shui was introduced to the United States by Lin Yun in the 1980s and drops the compass entirely, aligning the bagua to the front door instead. It is the source of most American feng shui writing. It is a real lineage with its own logic, but it is a twentieth-century simplification rather than a branch of the classical tradition.
Why does feng shui advice online contradict itself so often?
Because writers mix schools without saying so. Compass and BTB place the bagua differently, so they disagree about where your wealth corner is. Eight Mansions and Flying Star ask different questions about the same house and can rate it differently. The contradictions are usually not errors; they are answers from different systems presented as though there were only one.
