01Core principles
Core principles
Translate formulas into structure: what enters, how the model is arranged, and which relations drive interpretation.
Month and hour locate life and body palaces; birth day and a five-phase bureau place the Ziwei and Tianfu star groups, followed by auxiliaries, challenging stars and transformations. Palaces, qualitative states and major-minor-annual periods form the reading layers.
Key concepts
- twelve palaces
- fourteen major stars
- four transformations
- major and annual periods
02Origins and historical development
Origins and historical development
Keep traditional accounts, surviving evidence and later transformations distinct.
The system absorbs astral, twelve-palace and fate-calculation vocabularies. A datable early witness is the late-Ming Ziwei Doushu Jielan. It was re-systematized in twentieth-century Taiwan, Hong Kong and overseas communities.
STUDY / Zǐwēi Dǒushù
Edition-specific Ziwei star placement
- Materials and inputs
- Lunar date/hour, leap-month treatment, palaces and transformation table
Research question
How do leap-month and transformation conventions affect a chart?
Practical exercise
Construct palaces then stars for fictional inputs, retaining each step. Isolate one transformation-table difference rather than presenting a mixed system.
03Evidence limits and research debates
Evidence limits and research debates
Distinguish traditional interpretations, documented material and claims requiring testing.
Most of its stars function as internal symbols, without a direct correspondence to real-time celestial positions. Claims of invention by Chen Tuan or a preface by Luo Hongxian are textually disputed.
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.
