▣ Authentic Expert App for Integrated Saju & I Ching ▣

"An authentic Saju app that faithfully reproduces the original texts of Myeongnyeonghak and I Ching."

━━━━━━━━━━━━━━━━━━━━━

🎯 Why This App Is Different

━━━━━━━━━━━━━━━━━━━━━━

1. An authentic Saju app that faithfully reproduces 8 original texts

• Ziping Zhenquan · Gungtong Baojian · Ditian Shui Chanwei · Sanming Tonghui · Yuanhai Ziping · Meihua Yishu · Zhouyi Benyi · Qingzheng Qinding Xieji Bianfangshu — Includes the original Classical Chinese texts and direct Korean translations of over 2,800 paragraphs from the eight major classics of Myeongri and I Ching directly within the app.

2. We Don't Just Tell You What You Want to Hear

• Intentionally excludes positive bias, exaggeration, and "lucky fortune-telling" style expressions.

• Delivers information without addition or subtraction, based on the deterministic calculation formulas of ancient texts.

• Interprets based on logic regarding the trigrams, lines, patterns, and favorable elements, rather than definitive conclusions like "Great Fortune" or "Great Misfortune."

3. Result-Oriented Myeongri × AI Explains It Easily

• The rule engine handles all principle calculations, such as the calendar, patterns, and favorable elements — leaving no room for AI illusions to intervene.

• Only the commentary section is explained by AI using everyday language, making it an authentic app usable by both beginners and long-time students.

• Automatically switches to the rule engine template in the event of a network failure to ensure constant operation.

4. "Why is this result obtained?" — Provide the basis

• Sources and quotations from original texts such as Japyung Jinjeon, Gungtong Bogam, and Jeokcheonsu Cheonmi are enclosed below every explanation.

• For the daily fortune score, the details of additions and subtractions for all 67 factors (Yongsin, Gyeokguk, Sinsal, Hapchung, Johu, Gangyak) are fully disclosed.

• No judgments are made without basis.
