How to Cast Plum Blossom from an Observed Event
Last updated 10/7/2026
The external event method begins when you select and record something that happens in the environment as the casting cue.
A sound interrupts. A door opens. A bird calls. A glass breaks. A message arrives. Someone mentions a direction. An object falls. Selecting the event makes it an input for this exercise; it does not establish that the event was fated or predictive.
Prerequisite: know the signal-selection, number, and Ti/Yong rules. Your output is one event record with raw observation, chosen conversion, arithmetic, interpretation, confidence, and later review.
The Rule
Use the event that actually drew attention.
Do not scan the room for a better omen after the question is asked. Do not keep adding details until the reading sounds impressive. Choose the cue, write it down, and convert it.
UAYA uses the filter new change, new movement, new event. It is a selection control, not a verified quotation from Shao Yong. A candidate cue should arrive, shift, sound, open, fall, appear, or otherwise become distinct. Background conditions already present before the question are left alone unless they were part of the predeclared input.
Event Inputs
| Cue | Possible number source |
|---|---|
| Sound | number of knocks, calls, chimes, words, or repetitions |
| Direction | direction from which the cue comes |
| Object | count, color, trigram correspondence, position |
| Movement | entering, leaving, rising, falling, opening, closing |
| People | number present, role of person entering, direction of movement |
| Time | time the event occurred |
The method becomes strong when the cue has a clear relation to the moment.
Claim source: received Meihua Yishu, vol. 1, contains object-number, sound, person/object, and observed-event examples. Sun's 2006 modern presentation, p. 46, also lists unusual encounters, colors, date/time, sounds, and direction. UAYA's precommitment and stopping rules are editorial safeguards.
A Reproducible Flow
- State the question.
- Record the event.
- Decide what part of the event gives the upper trigram.
- Decide what part gives the lower trigram.
- Decide how to find the changing line.
- Calculate.
- Interpret with Ti/Yong, Five Phases, hexagram text, and context.
Course Case
Example type: invented teaching case. It reports no actual client and no outcome.
Question: “Does this workshop proposal have life in it?”
Event: as the question is asked, three messages arrive in a group chat. The clock reads 14:27.
Chosen rule:
| Role | Input | Calculation | Result |
|---|---|---|---|
| Upper trigram | event count, 3 messages | 3 divided by 8 | Li, Fire |
| Lower trigram | visible clock, 14 + 27 = 41 | 41 divided by 8 | Qian, Heaven |
| Moving line | 3 + 41 = 44 | 44 divided by 6 | line 2 |
Primary hexagram: Hexagram 14, Great Possession.
Changed hexagram: Hexagram 30, Clarity.
Interpretive start:
- Observation: Li (Fire) is above Qian (Heaven/Metal), and line 2 moves in the lower trigram.
- Ti/Yong rule: unchanged upper Li is Ti; changing lower Qian is Yong.
- Lineage relation: Ti Fire controls Yong Metal.
- Textual prompt: Hexagram 14, line 2, supplies a vehicle/carrying image.
Testable reading:
The visible idea may be able to discipline its delivery vehicle, but that control will take work. Clarify the format, audience, and practical container before increasing promotion. Confidence is medium because the same Fire-over-Metal relation could also describe excessive control.

Event Quality
Use this filter:
| Strong cue | Weak cue |
|---|---|
| Sudden, specific, recordable | Vague atmosphere |
| Connected to the question moment | Chosen later to fit the answer |
| Easy to count or describe | Requires elaborate symbolic invention |
| Used with a fixed rule | Reinterpreted after the result |
If the student notices the clock only after calculating from the messages and adds it to improve an awkward result, the exercise fails. Record invalid—rule changed after calculation and stop. Do not recast immediately.
Practice
For one week, record only three external-event readings. Do not overdo it.
For each one, write:
- Question.
- Event.
- Why that event counted.
- Formula.
- Hexagram.
- One-sentence interpretation.
- Later outcome or correction.
The practice is not to see signs everywhere. The practice is to notice when a moment has a clean signal and to handle it without inflation.
Next, learn the direct number version. Continue to The Numerical Calculation Method.
