## Key facts

- Charts are computed by a deterministic calculation engine (24 solar terms for BaZi month pillars; lunar calendar for Zi Wei), never simulated by a language model
- 1,300+ curated classical verdicts (San Ming Tong Hui, Lu Bin-zhao and Ling Dong-lai Zi Wei lectures) are matched to the exact chart configuration before any text is written
- Every generated chapter passes factual validation — star names, transformations (化禄/化权/化科/化忌) and brightness must exist in the real chart — with automatic rewrite on failure
- Verdicts carry life-domain tags (career, wealth, love, health, social) and must be grounded in concrete life scenarios in the output
- Languages: English (yueji.ai), Simplified Chinese (yueji.chat), Traditional Chinese UI
