menh.guruXuánkōng Flying Star — Build the 3×3 Cửu cung energy map of your home by facing direction and time period
Xuánkōng Flying Star on menh.guru draws your home's "energy map": a 3×3 Cửu cung chart computed from the sitting–facing axis (24 Mountains) and the time period — each period lasts 20 years. Every palace carries a trio of stars: the mountain star (health, people), the facing star (wealth, career) and the period's base star, showing whether that sector is thriving or waning during the current period.
The flow is simple: measure the house facing with your phone's sensor or enter degrees manually → enter the construction or major-renovation year (left blank, the chart uses the current period — Period 9, 2024–2043 — flagged as assumed) → the system lays the Cửu cung chart → pick a palace to read, such as the front-door sector, the workspace zone or the bedroom area → get an interpretation → keep asking Thầy Huyền Thanh about that same chart.
You can save up to 10 spaces (home, office, shop) with their facing and move-in year to reopen them quickly without measuring again. The chart is always recomputed server-side from the saved data — never taken from the client.
This is a traditional feng shui reference system for arranging space — not a scientifically proven causal relationship. To check whether a direction suits a person's destiny palace (Sinh Khí, Thiên Y… under Bát Trạch), use the Feng Shui Compass at /app/compass — the two tools look at a home through different layers.
Câu hỏi thường gặp
What is Xuánkōng Flying Star?
Xuánkōng Flying Star (Huyền Không Phi Tinh) is a traditional feng shui system that maps a house's qi along two axes: its 20-year time period and its sitting/facing direction. The result is a 3×3 Cửu cung chart — the home's “energy map” showing which sectors are thriving or waning. It is a traditional reference system, not proven causality.
What is a home's energy map?
“Energy map” is the everyday name for the Flying Star Cửu cung: the home's nine sectors, each carrying a trio of stars — the mountain star (health, people), the facing star (wealth, career) and the period's base star. Reading it tells you which areas are supported by the current 20-year period.
What do the mountain, facing and period stars mean?
Each palace of the chart holds three star numbers: the mountain star (sơn tinh) governs health and people, the facing star (hướng tinh) governs wealth and work, and the period star (vận tinh) is the base star of the 20-year period. menh.guru shows all three with a timeliness label (thriving, growing, waning, dead…) so you can read them at a glance.
Why does the tool ask for the construction year?
Flying Star divides time into 20-year periods — Period 8 (2004–2023) and Period 9 (2024–2043). The year the house was completed or last renovated fixes its period. Left blank, the chart is computed for the current period and flagged as assumed; you can update the year later for a precise chart.
How do I use the Flying Star feature?
Measure the house facing with your phone or enter degrees → enter the completion year if known → the system lays the Cửu cung chart → pick a palace to read for your purpose (front door, workspace, bedroom…) → then keep asking Thầy Huyền Thanh about that same chart.
Can I save my home's chart?
Yes. A signed-in account can save up to 10 spaces — home, office, shop — each with its facing and move-in year. Reopening a space recomputes the chart server-side from the saved data, so it always stays consistent.
How is Flying Star different from the Bát Trạch compass?
The compass at /app/compass matches a person's destiny palace to directions (Sinh Khí, Thiên Y…). Flying Star ignores birth data — it reads the house's own qi by space and time period. The two systems answer different questions and are used side by side.
Is the Flying Star result reliable?
The Cửu cung is computed by a fixed engine from the facing and year you enter — exact under the traditional formula. The AI interpretation is advisory within that system, not a certain prediction of the future. Treat it as one lens for arranging space, alongside practical factors like light, walkways and function.
Do I need an account to view a chart?
You can read the introduction and how it works without signing in. Laying a chart, getting the detailed interpretation, saving spaces and Q&A with Thầy Huyền Thanh require a menh.guru account.
