01Core principles
Core principles
Translate formulas into structure: what enters, how the model is arranged, and which relations drive interpretation.
An event was located by star office or celestial station and then assigned to its terrestrial field. Mappings changed with administrative geography, state genealogies, terrain and inherited schemes.
Key concepts
- celestial territories
- twenty-eight lodges
- twelve stations
- states and provinces
02Origins and historical development
Origins and historical development
Keep traditional accounts, surviving evidence and later transformations distinct.
Pre-imperial texts correlate heaven with states; Han treatises systematized the practice. Later dynasties repeatedly revised tables as territories and governments changed, applying them to war and politics.
TEXT / METHOD / EVIDENCE
From sky regions to terrestrial fields
A useful comparison of field systems identifies the units, version and direction of each correspondence. Recording relations individually reveals where two tables diverge.
Lodges, stations and terrestrial names
A lodge name, a degree within a lodge, a station and a terrestrial name are different fields. A working row can contain celestial start, end, station, branch and terrestrial designation. Mark absent information as unrecorded. Supplementing a gap from another table creates an editorial reconstruction that must remain distinguishable from the witness.
Section 2 of the English translation of Or.8210/S.3326 presents relations among lodge degrees, branches, stations and terrestrial names. It provides a locatable comparison witness. Romanised names still require checking against Chinese graphs, particularly when different names share a spelling; transliteration alone is not a reliable merge key.
One-to-many relations and variant tables
For an original teaching model, treat sky regions and terrestrial names as two sets of nodes. Draw one edge for each attested correspondence. Preserve both one-to-many and many-to-one relations. Their presence may raise questions about naming, arrangement or textual variants; silently deduplicating them prevents those questions from being examined.
Compare tables using four categories: shared relations, unique to A, unique to B and unresolved matches. Declare name-normalisation rules before computing differences. Identical labels with different meanings or boundaries should remain versioned entities. A clean-looking joined dataset can otherwise conceal the very historical variation under investigation.
Placing historical names on a map
A place name can denote a polity, administrative unit, cultural region or settlement. State which interpretation the map uses before consulting period-appropriate geography. Present-day boundaries can supply orientation, but assigning a modern province's outline to an ancient state introduces a claim about borders that the text may never make.
Represent uncertainty explicitly: an approximate centre, a provisional outline, or an indexed name without a polygon. Attach the relevant time frame. A partial, traceable mapping can be compared and revised; an apparently complete territory without provenance obscures its assumptions. Keep disputed placements visible in the accompanying data.
A four-step research record
Transcribe the witness
Retain names, sequence, gaps and editorial marks; assign each relation a stable ID.
Declare the units
State whether the unit is a lodge, station, asterism or place; keep levels separate.
Compare relations
List shared and unique relations, retaining unresolved identifications separately.
Interpret the context
Propose explanations for differences and identify the additional evidence each requires.
WORKED EXAMPLE
From material to claim
Original exercise with fictional labels: table A has Sky A→Land 1 and Sky B→Land 2; table B has Sky A→Land 1 and Sky B→Land 3.
Sky A→Land 1 is shared. The difference concerns Sky B's terrestrial correspondence. These rows alone establish neither chronological priority nor a territorial change.
- Do identical place labels denote the same entity?
- Does the table permit multiple correspondences?
- Could an editorial change explain the difference?
Review questions
Can tables be merged without version or date labels?
That would hide conflicting relations. Retain source, date range, original and normalised labels, and allow concurrent alternatives.
How should repeated romanised names be handled?
Check the original graphs and context before identifying the names. Preserve separate record IDs until that check is possible.
STUDY / Fēnyě Zhān
Political geography in field allocation
- Materials and inputs
- Celestial region, place names, administrative period and table
Research question
Does one place name identify the same territory in different periods?
Practical exercise
Compare three place names across two allocation tables, noting administrative level, period and celestial region. Map only documented extents.

Evidence limits and research debates
Distinguish traditional interpretations, documented material and claims requiring testing.
Historical field tables conflict; they are not fixed astronomical-geographic coordinates, and modern maps cannot recover a single original scheme.
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.
