Is this a medical diagnosis?

No. TianJi provides educational wellness information based on traditional Chinese medicine theory. It does not diagnose, treat, cure, or prevent disease.

Does "yunqi (运气)" mean personal fortune?

No. Here, yunqi refers to the five movements and six qi — classical climate rhythms, not personal luck. See the glossary entry for the canonical explanation.

Why do different people get different advice?

The same computed climate pattern can emphasize different wellness directions depending on constitution, region, and which Yunqi layer is active. The engine computes deterministically; retrieval grounds advice in classical text.

AI translates and formats retrieved classical passages. It does not compute Yunqi patterns or invent citations. A citation verifier and safety filter run before output is shown.

What is the anonymous quota?

You can generate 3 climate-health cards per day without signing in. Additional generations prompt login.

Reference Calculators

Instant · Deterministic · No login required

This hub gives you direct access to seven deterministic Yunqi calculators — Ganzhi pillars, solar terms, annual movement, Sitian/Zaiquan roles, six-step overlays, calendar ranges, and assimilation flags. Each calculator produces a pure computation from classical stem-branch formulas; nothing is generated, inferred, or guessed. Calculations are verified against the native TypeScript Yunqi engine (@repo/yunqi-calc) with golden regression tests. For real-time climate-health interpretation of these patterns, visit today's climate-health card or explore our glossary of classical terms.
