Select the subject before reacting to the chart.

The governing rule is simple: the question determines the target role; the chart supplies the candidate line. Movement, strength, World/Response position, and transformation can help distinguish candidates later. They do not decide what the question was about.

Keep four steps separate

  1. Copy the question without broadening it.
  2. Underline its single subject.
  3. Choose the selection method and target role.
  4. Only then locate a candidate on the chart.

If step 2 produces two unrelated subjects, split or refuse the question before selection.

One chart, three learner tasks

The following comparison reuses one chart to practise routing. Only the first row is the historical question. The other rows are learner exercises; they make no claim about a real event or outcome.

Task applied to the chartMethodTargetWhy
Source question: a same-day observation of clear or cloudy skiesSix RelativeChild, Yin Wood, line 2The source selects the Child line for this weather task; the visible line is moving
Identify the chart position assigned to the casterWorldWorld markerThe task asks for the chart’s self-side position, not a domain role
Identify the position assigned to an unfamiliar external sideResponseResponse markerThe task asks for the chart’s other-side position

The underlying chart is unchanged: Zengshan Buyi records Hexagram 3 changing to 19, with lines 2 and 5 moving, in Chen month on a Ji-Mao day. Its weather passage identifies the Child role, which the displayed bottom-up chart places at line 2.

The comparison is not permission to change a real question after casting. It is a classroom exercise showing that the line selected depends on the declared task.

What the chart may and may not do

The chart may show that:

  • the requested role appears once, more than once, or not visibly at all;
  • a candidate is moving, static, void, or transformed;
  • World or Response is attached to a candidate.

The chart may not repair a vague intake. If the question is “Tell me everything about this situation,” no amount of movement supplies a single target. Narrow the task or stop.

Worked selection record

Example type: documented textual case, mechanics only.

FieldEntry
QuestionSame-day clear/cloudy observation
SubjectSky condition during that day
MethodSix Relative
TargetChild, Yin Wood, line 2
Chart locationVisible primary line, moving
ConfidenceHigh for reproducing the source’s selection; no claim about predictive validity

The text’s later interpretation and recorded observation are outside this lesson. Target selection ends once the line and rationale are recorded.

Trap and stopping condition

Do not select line 5 merely because it also moves. The source discusses line 5 later, but movement alone does not replace the selected target.

Stop when the subject cannot be stated in one line without “and.” Split the intake, and do not manufacture a second answer from the same cast.
