How to Build a Flying Star ChartMeasure right → plot right → interpret right
Follow one exact sequence from frontage measurement to time overlays. Accuracy in the first three steps determines everything that follows.
Before you begin
Gather four reliable inputs.
Level compass
Use a reliable instrument or calibrated phone outdoors, away from metal and electronics.
Floor plan
Use a plan or accurate sketch showing the main building mass, rooms, doors, and openings.
Period evidence
Collect enclosure, completion, occupation, and any major renovation dates.
Mountain reference
Keep the 24 Mountains degree table ready before classifying the averaged bearing.
Cross-check before measuring: Compare roads, open space, light, view, activity, balcony or window exposure, and daily living orientation. The true frontage is an environmental conclusion—not a compass reading taken at a guessed wall.
Interactive workflow
Complete the chart in seven locked steps.
Tick each item only after its evidence is recorded. Progress stays on this page until it is reloaded.
Confirm Facing and Sitting
Find the true active frontage through openness, light, view, and use. At the façade center, measure outdoors away from metal; take at least three readings and average them.
Identify the property Period
Use the effective enclosure, completion, or first-occupation evidence. Major roof-off structural works may create a re-perioding question; cosmetic work normally does not.
Map the degree to a 24 Mountain
Convert the averaged azimuth to the correct 15-degree Mountain. For example, S2 is Wu at 172.5°–187.5°. The Sitting Mountain is exactly 180° opposite.
Plot the natal chart
Align the nine-palace grid to the confirmed Facing. Populate Base, Mountain, and Facing/Water stars using one consistent lineage method or the verified calculator.
Label rooms, functions, and occupants
Mark the main door, bedrooms, stove, desks, living areas, bathrooms, circulation, long-use work zones, and the people who occupy them.
Layer annual and monthly stars
Keep the natal chart fixed. Add annual stars for the year’s broad map and monthly stars to refine timing for sensitive palaces, doors, beds, work, and renovation.
Interpret by function, form, and evidence
Read doors for opportunity and movement, beds for people and rest, stove for household operations, and desks for sustained output. Make restrained changes and observe real results.
Nine-grid demo
Orient the grid to the confirmed Facing.
This reference shows the directional palaces and trigram roles. It is not a finished chart until the property’s Base, Mountain, and Facing stars are assigned.
- Rotate the analytical grid to the building’s confirmed facing line—not the page or screen.
- Place the frontage in its actual palace and Sitting exactly opposite.
- Map rooms and occupants proportionally after the grid is aligned.
- The Center influences the property as a whole.
Common pitfalls
Five errors that corrupt everything downstream.
First compare openness, view, activity, exposure, and the way daily life engages the exterior.
Frames, gates, vehicles, wiring, devices, and reinforcement can distort the azimuth.
Flying Star requires a precise 15-degree Mountain such as S1 Bing, S2 Wu, or W1 Geng.
Document enclosure, completion, occupation, and any potentially qualifying structural rebirth.
A mathematically correct chart still needs beds, doors, desks, stove, occupants, circulation, and external form.
Annual or monthly precision cannot repair a wrong frontage, Mountain, Period, or natal flight.
Accuracy audit
Five checks before interpretation.
Readings
At least three outdoor measurements were reconciled and averaged.
Facing
The active frontage was chosen through exposure and use before measuring.
Mountain
The exact 15-degree sector and 180° opposite Sitting were confirmed.
Period
Enclosure, occupation, and renovation evidence support the selected Period.
Usage
Rooms, occupants, doors, beds, stove, desks, and overlays are labeled.
Degree precision: Aim for stable repeat readings, not false decimal certainty. Bearings near a 24-Mountain boundary require extra measurements and professional judgment because a small error may change the chart.
Supporting references
Keep each source beside the step it controls.
Ready to plot?
Lock the Facing, Period, and Mountain first.
Once those three inputs are trustworthy, generate the natal chart, map the property’s rooms and occupants, run the audit, and only then add annual and monthly timing.
