Daovian’s Yijing module is a study path: given a King Wen query, the engine returns recomputable structure facts plus that hexagram’s public-domain judgment text. It is not a daily oracle, and it does not pack Najia in the same UI.
What the engine returns
- King Wen number 1–64 and Chinese name
- Six-line binary (bottom→top, yang=1, yin=0) and upper/lower trigrams
- Line yin/yang rows
- Zhouyi judgment text (卦辞)
Same query → same JSON. Rule IDs are listed under Yijing on the Method page.
Split with Liu Yao
| Yijing | Liu Yao | |
|---|---|---|
| Goal | Read structure + judgment | Cast and pack |
| Plate | No Najia | Jing Fang Najia |
| Entry | /modules/yijing |
/modules/liuyao |
If you need casting, use Liu Yao. If you need “what is this hexagram and its judgment,” use Yijing.
What we refuse
- Unsourced fate verdicts
- Calling study facts a complete divination
- Silently switching to Najia inside Yijing
