📖 Interpretation Rules by Scenario

Scenario 1: No Changing Lines

All lines are 7 or 8—no changes.

Read: Primary hexagram's judgment only

Scenario 2: One Changing Line

Only one 6 or 9—most common.

Read: That changing line's text in primary hexagram

Scenario 3: Multiple Changing Lines

2-5 changing lines—more complex.

Read: Relating hexagram's judgment primarily, with changing line texts as support

Scenario 4: All Six Change

Extremely rare—all lines changing.

Read: "Use" line if present; otherwise relating hexagram's judgment

⚠️ Common Mistakes to Avoid

Mistake 1: Repeatedly Asking Same Question

Consulting multiple times because you don't like the answer.

✅ Correct: Wait for circumstances to change or reach a new decision point.

Mistake 2: Binary Yes/No Questions

"Will it rain tomorrow?" "Will I win the lottery?"—unsuitable.

✅ Correct: Ask open-ended questions like "What should I consider about this career choice?"

Mistake 3: Treating Results as Absolute

Taking hexagram texts as prophecy and relying entirely on them.

✅ Correct: Use as a thinking mirror; combine with reality and common sense.
