01Core principles
Core principles
Translate formulas into structure: what enters, how the model is arranged, and which relations drive interpretation.
Nested units unfold one grand cycle into meetings, revolutions and generations, mapped to pre-celestial diagrams and hexagram sequences; related sections use sound and number to discuss transformation.
Key concepts
- yuan-hui-yun-shi cycles
- pre-celestial hexagram order
- observing things
- sound, pitch and number
02Origins and historical development
Origins and historical development
Keep traditional accounts, surviving evidence and later transformations distinct.
Shao Yong developed the system in the Northern Song; disciples and later scholars organized and diagrammed it, profoundly influencing Song-Ming correlative Yijing studies. Numerous predictive systems later borrowed its name.

Time scales in Huangji jingshi
- Materials and inputs
- Cycle tables, figure sequence, edition and chronology
Research question
How are numerical cycles connected to historical narrative?
Practical exercise
Reconstruct one scale conversion with units and intermediate steps. Keep calculations separate from assigned historical events and trace the source of each mapping.
03Evidence limits and research debates
Evidence limits and research debates
Distinguish traditional interpretations, documented material and claims requiring testing.
The original work is primarily cosmology and philosophy of history. Later dynastic predictions, numbered oracles and secret methods under Shao's name cannot all be read back into it.
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.
