Classical Xuan Kong fengshui (玄空风水) divides time into 20-year periods. Period 9 runs 2024–2043, governed by the Li trigram (離) — Fire, South. Fire-element trades (F&B-cooking, beauty, tech-with-visibility, media) get a 20-year tailwind. Water-element trades face mild headwind. Every commercial unit inherits a fresh qi overlay in 2024, regardless of how it performed in Period 8.
| Aspect | Period 8 (2004–2023) | Period 9 (2024–2043) |
|---|---|---|
| Trigram | Gen (艮) — Earth | Li (離) — Fire |
| Direction | Northeast | South |
| Favored trades | Property, construction, banking | Tech, media, F&B-cooking, beauty |
| Hot SG zones | NE suburbs, Bishan / AMK | CBD-south, Marina, Orchard |
| Building posture | Square, concrete, granite | Tall, glass-with-warmth, illumination |
Not necessarily. Period 9 is a modifier, not a replacement. Units continue performing if the operator + trade + underlying classical qi profile remain strong. What changes is which units get an additional tailwind versus a mild drag.
Moving costs money. Period 9 alone is rarely a reason to move. It IS a reason to re-evaluate before signing a new lease, before a major fit-out, or before expansion. The S$99 audit is exactly that re-evaluation tool.
On average, ~10–15% of the total score. In special configurations (south-facing fire-trade in a fire-favored sector), it can reach 25%+. In others (sector + trade orthogonal to Period 9 themes), near zero. The audit surfaces the Period 9 contribution explicitly so you can see the weighting.
Yes — Period 10 starts in 2044, governed by the Kan trigram (Water, North). 18 years to plan.
| Locale input | Period 9 modifier |
|---|---|
| Building facing | South facings get +3 to +10 baseline. North facings −3 to 0. |
| Flying-star chart | The chart itself; everything else modifies this. |
| Surrounding sha | South-pointing sha is slightly more disruptive (fire-on-fire). |
| Road configuration | Water ke-controlling fire is one of the strongest Period 9 dynamics. |
| Sector qi | Sector × trade × Period 9 table is the proprietary calibration headline. |
| Building shape + material | Pointed / tall / glass-warm = +. Squat / heavy-earth = −. |
| Entrance | Wide / visible / illuminated = +. Hidden / recessed / dim = −. |
| Support (背山) | Less period-sensitive. |
| Frontage | Visibility-rich = +. |
The S$99 audit makes the Period 9 contribution to your score explicit — you see whether the period is lifting you, draining you, or neutral, and by roughly how much. If you're about to sign a new commercial lease in 2026–2030, Period 9 is one of the most asymmetric inputs in the framework: matching it adds a structural tailwind that lasts to 2043; ignoring it can cost you a 5–15 point swing on a score that determines whether the location is workable.
