Core principles
Translate formulas into structure: what enters, how the model is arranged, and which relations drive interpretation.
Najia inserts temporal signs into hexagram lines; the Eight Palaces arrange the sixty-four hexagrams through transformations and assign host-response positions; hexagram qi maps sequences onto annual and seasonal time.

02Origins and historical development
Origins and historical development
Keep traditional accounts, surviving evidence and later transformations distinct.
Han Yijing traditions associated with Meng Xi and Jing Fang are important sources, but the received Jing lineage texts and the complete later system were editorially layered. From Tang-Song times these components fed into Huozhulin and Wenwangke divination.
03Evidence limits and research debates
Evidence limits and research debates
Mystery belongs to the unknown—not to presenting uncertainty as fact.
The full later algorithm should not be attributed point by point to the historical Jing Fang, and Najia does not mean exactly the same thing in every source.
This dossier supports historical, textual and methodological study. Internal traditional explanations are not modern empirical validation and do not replace medical, legal, financial or other professional advice.
