Form School vs Compass School.
Form School is not Compass School. They are not rivals, and they are not two competing answers to the same question. They are the two halves of a single Classical practice. Each one asks a different question. One reads the place. The other reads the fit between the place and the people inside it. You may have already read the four feng shui schools, in one map. This page is the close-up on the divide that map only names.
What Form School reads
Form School (Luan Tou Pai, "mountain head school") reads the shape of the landscape and the shape of the built environment around a home. The working rule is older than the schools themselves: qi rides on wind, and it is stopped at water. A good site sits in the land the way a person sits in an armchair. Backed, embraced on both sides, open in front. The four positions name those qualities in a vocabulary the tradition has carried for centuries. The Black Tortoise behind is the back support, ideally a hill or a taller, stable structure. The Green Dragon on the left is the slightly higher, winding form on your left as you face out from the door. The White Tiger on the right is the lower, broader presence on your right. The Red Phoenix in front is the open, friendly foreground, a park, a square, a calm body of water. The animals are positions and qualities, not literal creatures.
In a city, buildings substitute for mountains and streets substitute for rivers. A curved street that wraps around your building is embracing. A straight road aimed at your front door is not. That second case is one example of sha qi ("cutting qi"). The term names the set of sharp forms aimed at a dwelling. The spear-road or T-junction case is the one most readers meet first. The full set belongs on the room-level walk in how to read any room.
What Compass School reads
Compass School (Li Qi Pai, "school of patterns and qi") reads the directional and numerical structure of a space. Every direction is treated as carrying a particular quality of qi, and that quality interacts with the person who lives there. The instrument is the luopan, the layered compass disc that holds the rings the tradition uses to measure a bearing. The personal layer most readers meet first is the Kua number and the Eight Mansions sub-school. It assigns each person four supportive directions and four cautious ones for life. For the full sub-school roster, see what Compass School actually covers, and for the personal entry point, use the Kua calculator.
Why Form comes first
Form first. Then Compass. The order is not random, and it reflects how the tradition is taught.
Form School answers the first question: is this place liveable in the first place? If the site is hostile, no compass reading rescues it. Picture a road aimed at the front door, no support behind, wind on every side. The working sequence most Classical practitioners follow is the same: site first, orientation second, household overlay third.
Compass School answers the second question: now that we know the place is liveable, how do we tune it for this specific household? That tuning is precise and personal. The tradition only applies that tuning on a foundation that Form has already cleared.
The two halves combine on the same vocabulary. Qi, yin and yang, the five elements, the Bagua. You can see that shared language at work on the page on what the Bagua is. What differs is what each half measures. Form gives the reading of the place. Compass gives the directional fit for the people. Form first. Then Compass.
When each leads
House-hunting and the walk-up assessment are Form School work. You stand at the curb. You look at the support behind, the embrace on either side, the foreground in front, and the line of the street. Choosing a bedroom in a settled home is Compass School work. So is picking a desk direction or planning a renovation around a household member. Eight Mansions is the personal layer. The third question, when to do the renovation, belongs to Flying Stars and the calendar layer, which is the subject of the next page.
Where to go next
- Ten seconds. Find your Kua number so the Compass layer has something personal to attach to.
- An afternoon. Read what Compass School actually covers for the four Compass sub-schools, then Flying Stars, BTB, and when timing enters the picture for the calendar layer.
- Deeper read. Work through the methodology page for the luopan, the 24 Mountains, and the Eight Mansions worked examples.
