Updated 2026-08-21
Qi Men Dun Jia and Liu Yao are both traditional Chinese divination systems, but their models and strengths differ. Choosing the right tool makes your question clearer.
1. Qi Men Dun Jia: A 3D Map of Time and Space
Qi Men is built on time-space. One chart shows heaven (stars), earth (palaces), people (doors) and spirit (eight spirits). It is best for:
- Overall trends and directions.
- Best timing and directions for action.
- Multi-party situations (workplace, love, business negotiation).
- Strategic choices and trade-offs.
For example, "Should I change jobs or stay?" Qi Men can compare Open Door (current job), Life Door (wealth), day stem (you) and more.
2. Liu Yao: One Question, One Hexagram
Liu Yao casts six lines from three coins, producing a main hexagram and changing lines. It is best for:
- Specific yes/no questions.
- The success or failure of a single event.
- Inner state and subconscious leanings.
- Short-term outcomes.
For example, "Will this interview succeed?" Liu Yao can judge directly from the useful line's strength and moving lines.
3. Which One When?
Question type — Recommended tool — Reason
Overall fortune, direction, timing — Qi Men Dun Jia — The chart is multi-dimensional and good for macro judgement.
Single event success/failure — Liu Yao — The hexagram is focused and direct.
Relationship direction — Either — Qi Men shows the structure; Liu Yao shows the mindset.
Health concerns — Either, but see a doctor — Metaphysics can only assist, not replace diagnosis.
4. Can You Use Both?
Yes. Many practitioners use Qi Men for the big picture and Liu Yao for confirmation. Beginners should focus on one first, then add the other.
Disclaimer: Both are traditional tools. Results are for reference only and cannot replace professional judgement.
FAQ
Which is easier to learn?
Liu Yao is usually faster to start because it centres on one hexagram. Qi Men has more symbols and takes longer to learn.
Can the two systems contradict each other?
Sometimes, because they view the matter from different angles. When they conflict, return to real-world information and rational judgement.
Can AI readings replace a master?
AI can quickly organise chart information and traditional meanings, but it cannot replace an experienced master's intuition and life experience. Use AI as an assistant.
