About TianJi Health
Last updated: July 2026
TianJi Health turns WuYun-LiuQi (五运六气) from the Huangdi Neijing · Suwen into practical Climate-Health Cycles — seasonal wellness education computed from stem-branch calendars and classical climate theory, not fortune-telling or personal luck prediction.
What we do
- Deterministic Layer-1 Yunqi calculation in an auditable TypeScript engine (@repo/yunqi-calc) — date in, calendar pattern out, no LLM in the math.
- Exact-key classical retrieval before any AI wording: fixed knowledge keys and source passages first, then readable translation.
- Conservative safety boundaries on every card and report: general wellness education only, citations attached, diagnosis-style language blocked.
How the three layers work
- Layer 1 — Calculate: Gregorian date → stem-branch year (Dahan boundary) → yearly movement, host/guest qi, and six steps. Pure computation.
- Layer 2 — Single-dimension cards: One climate layer at a time (year movement, half-year host/guest, or guest-host overlay) with classical grounding.
- Layer 3 — Seasonal plan: Multi-layer synthesis with retrieval and citation checks for a fuller educational report — still not a clinical consultation.
What we are not
- Not a medical device, clinic, or diagnostic service
- Not personal luck / 运势 prediction or astrology entertainment
- Not a replacement for qualified healthcare professionals
Expertise & transparency
Product boundaries, citation verification, and safety filters are documented in our architecture decision records. Every card and report is meant to show its classical source and an educational disclaimer. If a claim cannot be grounded in retrieved sources, it should not appear as a citation.
How to use this site safely
Start with Today or a Layer-1 tool to see the climate pattern. Treat Layer-2/3 text as traditional theory in modern language. For symptoms, medication, or diagnosis, see a licensed clinician — this product stays on the educational side of the line.
