Zhai is methodology-driven commercial fengshui for Singapore — a documented framework, not a personal practitioner. Every audit scores 9 measurable locale inputs against your trade's five-element profile, then surfaces the top risks and levers in plain English. Five sub-pages below describe exactly what we check and how.
| Layer | What it does |
|---|---|
| Trade-element mapping | Every trade mapped to its primary + secondary five-element nature |
| Locale profiling | 9 inputs per unit: facing, Period 9, sha, road, sector, building, entrance, support, frontage |
| Scoring rubric | How the 9 inputs combine into a 0–100 score with verdict bands |
| Period 9 (2024–2043) | The current 20-year era, Li-trigram (Fire / South) governance |
| SG sectors | District-by-district qi profiles across Singapore |
| Product | Price | What you get |
|---|---|---|

Commission the audit — S$99 | Free compatibility check
You don't need to read the sub-pages to commission an audit — the report is written for non-practitioners. The methodology is published so you can verify what we look at and why a finding is reasoned the way it is, not so you have to learn classical fengshui. Every audit is stamped with the methodology version it was generated against (currently v0.1, 2026-05-17).
Everything on these methodology pages is public. The proprietary layer is the per-trade per-sector calibration table — the specific point weights applied to each combination of trade × sector × Period 9 × facing, derived from Zhai's audit case-study database. This is what's bought when you commission an audit; it stays internal by design.
Methodology versions are append-only. If the framework updates, prior reports remain valid against the version stamped on the PDF — a v0.1 audit doesn't become "wrong" when v0.2 ships, it just predates the revision.
Grounded in classical Xuan Kong fengshui (玄空风水) + Singaporean commercial real-estate observation. Maintained by Zhai — Commercial — Singapore.
