易经起卦

Core Workflow

Use the three-coin six-line method unless the user provides explicit line values.

1. Generate six lines from bottom to top.
2. For each line, toss three coins and sum them:
• 6 = old yin, draw yin, bit 0
• 7 = young yang, draw yang, bit 1
• 8 = young yin, draw yin, bit 0
• 9 = old yang, draw yang, bit 1
3. Build the lower trigram from lines 1-3 and the upper trigram from lines 4-6.
4. Create the lookup key as upperBits-lowerBits.
5. Read references/hexagrams.json and find the entry whose key matches.
6. Present the result in this order:
• six generated lines, bottom to top
• shortName
• three terms: keywords, fullName, summary
• a concise interpretation

Random Casting

When actually casting, randomly choose each coin as 2 or 3 with equal probability, then sum three coins. Do not choose the final hexagram directly.

If the user supplies line values, accept either:

• six values from the set 6, 7, 8, 9
• six yin/yang bits from bottom to top, where 0 is yin and 1 is yang

Reference Files

• Use references/hexagrams.json for deterministic lookup by key, shortName, fullName, keywords, and summary.
• Use references/summary.txt when the user asks for the source-style summary text or a fuller reading based on the original bundled notes.

Output Guidance

Keep the tone reflective rather than predictive. Avoid claiming certainty about future events. Prefer phrasing such as "可理解为", "提醒你关注", "适合反思", or "this suggests".

For Chinese requests, answer in Simplified Chinese. For English requests, use the English fields in hexagrams.json.
