01Core principles
Core principles
Translate formulas into structure: what enters, how the model is arranged, and which relations drive interpretation.
Numbers are reduced by eight or six to obtain upper-lower trigrams and a moving line. The body and function trigrams are distinguished, then compared through phase production-control, seasonal strength, nuclear and changed figures, and situational signs.
Key concepts
- body and function
- nuclear hexagram
- external correspondence
- triggering occasion
02Origins and historical development
Origins and historical development
Keep traditional accounts, surviving evidence and later transformations distinct.
The system claims lineage through Shao Yong's prestige, while earlier surviving witnesses are mostly Ming-Qing and interact with character and object divination. Its simple casting procedures encouraged wide modern transmission.
03Evidence limits and research debates
Evidence limits and research debates
Mystery belongs to the unknown—not to presenting uncertainty as fact.
Attribution to Shao Yong does not establish his authorship. Famous stories such as the plum-blossom omen belong to lineage narratives; their historical status requires independent evidence.
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.
