01Core principles
Core principles
Translate formulas into structure: what enters, how the model is arranged, and which relations drive interpretation.
Stems, branches, Hetu-Luoshu numbers and yin-yang generate a pre-celestial natal hexagram and original line; post-celestial, major-cycle and annual hexagrams are then arranged and read through line texts and numerical relations.
Key concepts
- heaven-earth numbers
- pre/post-celestial natal hexagrams
- original line
- annual hexagram
02Origins and historical development
Origins and historical development
Keep traditional accounts, surviving evidence and later transformations distinct.
A dated 1632 preface is among the earliest reliable witnesses; Ji Dakui and others revised the work in the Qing. Although linked to Chen Tuan and Shao Yong by attribution, evidence better supports late-Ming compilation.
STUDY / Héluò Lǐshù
Input sensitivity in Heluo lishu
- Materials and inputs
- Birth time, calendar convention, number sequence and change table
Research question
How do time boundaries and number conventions affect outputs?
Practical exercise
With a fictional date, trace stems-branches to numbers and figures. Change a time boundary and one numerical convention separately to locate their effects.
03Evidence limits and research debates
Evidence limits and research debates
Distinguish traditional interpretations, documented material and claims requiring testing.
Lineage claims must be distinguished from datable composition, and editions may differ in numbers, original-line rules and annual tables.
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.
