Double Appearance: Ranking Multiple Target Candidates
Last updated 10/7/2026
Double Appearance (两现, liang xian) occurs when the selected Six Relative appears on more than one visible primary line.
Do not hide the duplicate. Build a candidate record and state how, or whether, one line becomes primary.
Why there is no universal shortcut
The “Double Appearance” chapter of Zengshan Buyi first lists an older preference for the vigorous, moving, non-broken, non-void, and unharmed candidate. It then gives counterexamples that select a void or Month-Broken line instead. The chapter therefore does not support a fixed rule such as “always take the moving line” or “always reject the void line.”
UAYA uses the following course cascade to expose the decision. It is an explicit teaching convention, not a claim of timeless consensus.
The declared cascade
- Question fit. Remove any candidate that does not fit the exact subject or named side.
- Source-specific instruction. Apply a rule tied to the cited case or lineage, if one exists.
- Position relevance. Record World, Response, or another position explicitly required by the task.
- Activity. Record overt movement or an already-declared Dark Moving status; do not make it decisive by itself.
- Calendar condition. Record void, Month Breaker, and support without treating any one label as automatic deletion.
- Decision. Rank the candidates only if one now has a defensible advantage. Otherwise return
unresolved tie.
The confidence label must follow the evidence, not the desire to finish.
Candidate record
| Candidate | Question fit | Position | Activity | Calendar facts | Source-specific reason | Rank |
|---|---|---|---|---|---|---|
| Line __ | ||||||
| Line __ |
Neutral exercise
Example type: invented learner exercise. No outcome is supplied.
A practice chart contains two visible Child/Wood lines:
- line 2: Yin Wood, moving, not void;
- line 5: Mao Wood, static, not void;
- neither line carries World or Response;
- the exercise asks which moving Child line should be followed into its transformation.
The exact task gives line 2 the stronger fit because it explicitly asks for the moving Child line. Record:
- line 2: primary candidate, high confidence for this exercise only;
- line 5: retained as a same-role secondary line;
- no outcome judgment.
Change the task to “select the Child line” and the distinguishing phrase disappears. With no further source instruction or position relevance, the correct output is unresolved tie.
Common traps
- Treating void as “nonexistent.” It remains an observable candidate state.
- Treating movement as proof of relevance.
- Using World as a last-minute tiebreaker when the question did not make self-side position relevant.
- Converting a course cascade into a claim about every lineage.
- Lowering the confidence label after the fact instead of preserving the tie.
Claim source: Zengshan Buyi, “Double Appearance” (两现章), checked composite printed pp. 65–66. The source records both an older preference list and counterexamples selecting void or Month-Broken candidates. The six-step cascade and confidence labels are explicit UAYA teaching conventions.
