Two Schools of Feng Shui
Feng shui has two major schools: the Form School (形势派, xíngshì pài) and the Compass School (理气派, lǐqì pài).
The Form School reads the landscape — mountains, rivers, terrain shapes — to determine the flow of qi. It is intuitive, visual, and relatively accessible to non-specialists.
The Compass School uses mathematical calculations based on direction, time, and the occupant's birth data to determine optimal orientations. It is technical, precise, and requires specialized tools and training.
In practice, most feng shui masters use both schools. But the Compass School is the one that gives feng shui its reputation for complexity.
The Luopan (罗盘)
The luopan is the Compass School's primary tool. It looks like a compass surrounded by concentric rings of Chinese characters — anywhere from 4 to 36 rings, depending on the complexity of the instrument.
Each ring contains different data:
The Heaven Pool (天池) — The central compass needle, which points to magnetic south (not north, as in Western compasses).
The 24 Mountains (二十四山) — The innermost ring divides the compass into 24 directions (15 degrees each), combining the eight trigrams, the ten Heavenly Stems, and the twelve Earthly Branches.
The Flying Stars (飞星) — Rings that map the movement of qi through time, showing how the energy of a space changes over 20-year periods.
The Annual and Monthly Stars — Rings that track shorter-term energy cycles, used for timing important activities.
Reading a luopan requires years of training. The rings interact with each other in complex ways, and the interpretation depends on the specific question being asked.
How It Works in Practice
A Compass School consultation for a new building typically involves:
-
Taking the facing direction — The master uses the luopan to determine the building's precise orientation (to the degree).
-
Calculating the Flying Star chart — Based on the facing direction and the year of construction, the master creates a chart showing the distribution of energy throughout the building.
-
Identifying favorable and unfavorable sectors — Each sector of the building has a specific energy profile. Some are good for bedrooms, some for offices, some should be avoided entirely.
-
Recommending adjustments — If unfavorable energy cannot be avoided (because the building already exists), the master recommends remedies: specific colors, materials, water features, or objects that counteract negative energy.
The Time Dimension
What makes Compass School feng shui particularly complex is its incorporation of time. The energy of a space is not static — it changes in 20-year cycles (called "periods" or 运, yùn), annual cycles, monthly cycles, and even daily cycles.
A building that had excellent feng shui when it was built in 1984 (Period 7) may have problematic feng shui now (Period 9, which began in 2024). The physical building has not changed. The temporal energy has.
This time dimension is why feng shui masters recommend periodic reassessment — and why the same building can be considered auspicious by one master and problematic by another, depending on which time period they are calculating for.
Skepticism and Respect
Compass School feng shui has no scientific basis. The luopan's rings encode a cosmological system — the Five Elements, the Heavenly Stems, the Earthly Branches — that does not correspond to measurable physical phenomena.
But dismissing it as mere superstition misses its cultural function. The Compass School represents a sophisticated attempt to create order from complexity — to develop a systematic method for making decisions about space and time. The system is wrong about the physics. It is not wrong about the human need for frameworks that make the overwhelming feel manageable.
