01Core principles
Core principles
Translate formulas into structure: what enters, how the model is arranged, and which relations drive interpretation.
Different sources correlate generated numbers with directions, body parts, topics or positions. The Tsinghua Shifa offers unusually complete tables and judgment structures but does not represent every pre-imperial method.
Key concepts
- divinatory numbers
- hexagram positions
- Chu manuscripts
02Origins and historical development
Origins and historical development
Keep traditional accounts, surviving evidence and later transformations distinct.
Numerical hexagrams occur on bones, bronzes and Chu manuscripts. Some signs converged with the yin-yang line system; other procedures disappeared and survive only through excavated materials.
03Evidence limits and research debates
Evidence limits and research debates
Mystery belongs to the unknown—not to presenting uncertainty as fact.
Not every numerical hexagram belongs to the received Zhouyi, and visual resemblance alone cannot prove that a complete bagua system existed in prehistory.
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.
