Form School (Xingshi) judges a site by its physical shape — the hills, water, streets and building outlines around it — and reads chi as something that flows or stalls depending on that shape. Compass School (Liqi) instead calculates direction, using a compass called the luopan and the exact time a building was constructed or occupied. One reads landscape; the other reads numbers.
Both are older strands of the same broader tradition, and both predate the simplified Western version most readers encounter today. Understanding the difference matters because the two schools sometimes give different, even contradictory, advice about the same room — and most popular guides do not say which one they are using.
What does Form School actually look at?
Form School evaluates the physical shape of a landscape or building before anything else, looking for enclosure, a clear “armchair” formation of higher ground behind and open ground in front, and water that curves rather than rushes past a site.
Classical Form School texts describe an ideal site as backed by a protective rise (often called the “black tortoise” position), fronted by open ground, and flanked on both sides by lower, supporting elevations. This is a landscape-reading tradition first — it developed for choosing burial sites and settlement locations in hilly parts of southern China, long before it was applied to individual rooms or apartments.
Applied indoors, Form School logic tends to survive intact because it maps onto things a room actually has: a solid wall behind a bed rather than a window, a front door that does not open directly onto a wall, a hallway that lets air and light move rather than dead-ending. Where Form School gives a reason, it is usually a spatial one — sightlines, drafts, the shape of a passage — and that reason can be checked against the room itself.
What does Compass School actually look at?
Compass School (Liqi) calculates a building’s relationship to the eight compass directions and to time, using formulas such as the Flying Stars system, which assigns different qualities to each direction depending on the period in which a building was constructed.
The tool associated with this school is the luopan, a compass with concentric rings of Chinese characters recording directions, the eight trigrams, and other correspondences drawn from classical Chinese cosmology. A Compass School practitioner takes a precise directional reading of a building — often from its main door or a specific wall — and combines it with the construction date to work out which sectors are considered favourable or unfavourable in a given period.
This is a calculation-based tradition. Its conclusions do not follow from what a room looks or feels like; they follow from arithmetic applied to direction and date. That makes it harder for an outsider to verify by eye, and it is also why professional Compass School consultations are usually described, by their own practitioners, as requiring training and a proper compass reading rather than guesswork.
Where did each tradition come from?
Form School is generally traced to Jiangxi province in southern China, an area of pronounced hills and valleys where reading terrain for burial and settlement sites had obvious practical value. Compass School is more associated with Fujian province, flatter terrain where a directional, calculation-based method had more to work with than landform alone.
Both strands were absorbed into the same overall body of feng shui theory over centuries, and by the time it reached wider circulation, most practitioners drew on elements of both rather than following one exclusively. The split between them is a useful analytical distinction, not a claim that they operated as two separate, non-overlapping industries.
The background to both schools, and to feng shui as a broader tradition, is covered in more detail in Feng Shui Pack’s explainer on the origins of feng shui, which is worth reading before applying either school’s rules to a specific room.
Which one does most Western feng shui advice use?
Neither, strictly speaking. Most English-language books, magazine columns and apps use the Black Sect Tantric Buddhist (BTB) adaptation, a twentieth-century Western reworking that places the bagua map against the front door of a home regardless of which direction that door faces.
Classical Compass School would never do this — direction is the entire point of the calculation, and a bagua placed by door position alone ignores it. Classical Form School would not do it either, since its focus is landform and building shape, not a fixed symbolic grid overlaid on a floor plan.
This is the single most common point of confusion in popular feng shui content: a BTB rule is presented as if it were a universal, ancient law, when it is one twentieth-century adaptation among several traditions that frequently disagree with each other. Reputable coverage of the subject says which school a rule belongs to; where it does not, that is worth noticing.
Do the two schools ever agree?
Yes, on some fundamentals — but they arrive at them by different routes. Both traditions generally favour a bed with a solid wall behind it and a view of the room’s door, both are wary of a front door opening directly onto a staircase, and both treat clutter and blocked passages as undesirable.
Where they diverge is in how strictly direction and timing are weighted. A Compass School reading might flag a bedroom as unfavourable in a given period purely because of its compass orientation, even if the room is otherwise well laid out by Form School standards. A strict Form School reading would have little to say about that same bedroom’s compass direction at all, focusing instead on whether the space itself is enclosed, well-lit and free of awkward angles.
Where a rule from either tradition has no practical, checkable rationale behind it — a specific number of days, a particular trigram association, a rule tied purely to a construction year — that should be said plainly rather than dressed up as self-evident. No practical reason is given for many such rules beyond the tradition itself, and that is worth stating rather than glossing over.
Which school should guide a practical decision at home?
For most everyday questions — where to put a bed, how to arrange a hallway, whether a room feels closed-in — Form School’s landform logic is the more legible starting point, because its reasoning tends to map onto ordinary spatial sense: sightlines, airflow, an unobstructed path to a door.
Compass School questions, by contrast, generally require an actual compass reading and a trained interpretation of the correspondences it produces; approximating it with a rule of thumb misses the point of the method entirely. A reader wanting a genuine Compass School reading of a specific home is better served by a practitioner who states which system (Flying Stars, Eight Mansions, or another) they are using and why.
Either way, none of this is a substitute for structural, electrical or tenancy advice. Questions about damp, wiring, load-bearing walls or lease terms belong with a qualified surveyor, electrician or letting professional — feng shui, in either school, does not address any of them.
Is one school “more authentic” than the other?
No — both are long-established, textually documented strands of the same broader Chinese tradition, and neither has a stronger claim to authenticity than the other. What can genuinely be said is that BTB, the version most familiar to Western readers, is a modern adaptation distinct from both.
The most useful habit for a reader is not picking a “correct” school but noticing which one a given piece of advice is drawing on, since that determines whether a rule is about landform, about direction and time, or about a twentieth-century symbolic system layered on top of both. None of the three promises a specific outcome — what each offers is a framework for reasoning about a space, and practitioners within each tradition describe it in exactly those terms.
Further groundwork on how these traditions fit together, including the historical texts each school draws on, is collected in Feng Shui Pack’s Basics archive, which is the starting point for readers working through the subject from the ground up rather than the room down.
About this site. Feng Shui Pack explains what the feng shui tradition holds and which school holds it, from published sources. Feng shui is a tradition of placement and orientation, not a science: nothing here will bring you wealth, health, luck or a relationship, and we never claim otherwise. Where a suggestion has an ordinary practical reason — daylight, airflow, sightlines, less clutter — we say so; where it does not, we say that too. This is not medical, financial, legal or tenancy advice. If a decision matters, talk to a professional in that field.
