Qi Men Dun Jia Chart Setup Guide | Practitioner Charting Guide

## Foundational Setup: The Four Pillars and Temporal Anchors Before any plate can be drawn, ensure your **Bazi (Four Pillars)** conversion is precise. A single hour or day error cascades through the entire chart. Use a verified solar-to-lunar calendar tool — do not rely on memory for leap months or seasonal adjustments. **Key advice:** Always double-check the **Jia (甲) stem** position in the Hour Pillar. Qi Men’s entire escaping logic hinges on the Jia’s hiding place. If your Bazi’s Hour Pillar stem is incorrect, your Yin/Yang Dun base will be misaligned. ### Step 1: Determine Yin Dun vs. Yang Dun - **Yang Dun (阳遁):** Used for periods from the Winter Solstice (冬至) to the day before the Summer Solstice (夏至). The Jia stem moves forward (shun) through the 9 palaces. - **Yin Dun (阴遁):** Used from the Summer Solstice to the day before the Winter Solstice. The Jia stem moves backward (ni) through the 9 palaces. **Common mistake:** Practitioners often confuse the seasonal boundary with the lunar month. The rule is strictly solar-based. The exact moment of solstice (精确到分钟) determines the switch. If you are within 5 days of a solstice, manually verify the solar term (节气) table. ### Step 2: Determine the Dun Number (Ju Shu) The Ju Shu (局数) is the starting palace number where the Yi (乙), Bing (丙), Ding (丁) — the three qi — are placed. This is derived from the 24 solar terms and the day stem (日干). - Use the **Jie Qi (节气) table** to find which solar term governs the current day. - Cross-reference the day stem (Jia, Yi, Bing, etc.) with the solar term to find the Ju Shu from the standard lookup tables (e.g., "Winter Solstice: Jia day = Yang Dun 1 Ju, Yi day = Yang Dun 2 Ju..."). **Technical note:** There are 4320 possible Ju patterns, but only 1080 are unique due to symmetry. For daily practice, memorize the 72 standard Ju (36 Yang, 36 Yin) — these cover 99% of cases. --- ## Yin/Yang Escaping: The Core Mechanism ### Escaping (遁) Defined "Escaping" refers to the hidden movement of the Jia stem. In Qi Men, Jia is the leader but must be concealed to avoid harm. The three escaping methods are: 1. **Yi escapes Jia (乙遁甲):** Softness overcomes rigidity. Yi (乙) is the first of the three qi and represents a gentle, adaptive escape. 2. **Bing escapes Jia (丙遁甲):** Light overcomes darkness. Bing (丙) represents the sun’s power, a forceful escape. 3. **Ding escapes Jia (丁遁甲):** The star of wonder. Ding (丁) represents the moon and subtlety — the most refined escape. ### Practical Placement After determining Yin/Yang Dun and Ju Shu: - **Yang Dun:** Place the Yi, Bing, Ding sequence starting from the Ju Shu palace, moving forward (1→2→3...). - **Yin Dun:** Place the Yi, Bing, Ding sequence starting from the Ju Shu palace, moving backward (1→9→8...). **Example:** Yang Dun 3 Ju → Yi in Palace 3, Bing in Palace 4, Ding in Palace 5 (middle palace, which is then assigned to Palace 2 in most schools). **Important note:** The middle palace (Palace 5) always has no fixed position. In the rotating plate method, it is assigned to Palace 2 (Kun). In the flying plate method, it is assigned to the palace that governs the current season (e.g., winter = Palace 1). --- ## Rotating Plate Method (转盘) vs. Flying Plate Method (飞盘) ### Rotating Plate (转盘法) This is the more common method, especially for general divination (预测). The 9 stars (九星), 8 doors (八门), and 8 spirits (八神) rotate as fixed groups. **Setup steps:** 1. Place the 9 stars starting from the Ju Shu palace, moving forward (Yang) or backward (Yin) in the order: Peng (蓬), Ren (任), Chong (冲), Fu (辅), Ying (英), Rui (芮), Zhu (柱), Xin (心). - **Key:** The star that matches the Ju Shu palace’s original earthly branch is the "value star" (值星). 2. Place the 8 doors starting from the Hour Stem’s palace, moving in the same direction. - The door placed in the Hour Stem’s palace is the "value door" (值使). 3. Place the 8 spirits in a fixed clockwise order: Fu (符), She (蛇), Yin (阴), He (合), Hu (虎), Wu (武), Di (地), Tian (天). - **Note:** The spirit order never reverses — only the starting point changes based on Yin/Yang. **Common mistake:** Beginners often reverse the spirit order in Yin Dun. The spirits always rotate clockwise (顺). The "reversal" in Yin Dun only applies to the placement sequence of stars and doors, not spirits. ### Flying Plate Method (飞盘法) This method is preferred for military strategy (兵法和奇门遁甲) and high-level timing. Stars and doors "fly" along the 9-palace number path, not as fixed groups. **Setup steps:** 1. Determine the "value star" and "value door" as in the rotating method. 2. Instead of rotating as a block, place the remaining stars and doors by following the **nine-palace flying sequence**: 1→2→3→4→5→6→7→8→9 (or reverse for Yin Dun). 3. The spirits are also placed by flying, but the sequence is: Fu, She, Yin, He, Hu, Wu, Di, Tian — each assigned to a palace in numerical order. **Practical difference:** - Rotating plate: Stars and doors maintain their relative positions (e.g., Peng is always next to Ren). - Flying plate: Stars and doors can appear in any palace, creating more dynamic combinations. **Which to use?** - **Rotating plate:** For daily life, business, relationships — the "softer" applications. - **Flying plate:** For timing critical events, military/competitive situations, or when you need to break a deadlock in a reading. **Important note:** If you mix methods (e.g., rotating stars with flying doors), the chart will be incoherent. Choose one method per chart and stick to it. --- ## Cross-Verification: Avoiding Dead Charts A "dead chart" (死局) occurs when the plate is mathematically correct but yields no actionable information. This happens when: 1. **The Jia stem is too exposed** — if Jia appears in the Hour Pillar’s palace without a hiding Yi, Bing, or Ding, the chart is "naked" and unreliable. 2. **Yin/Yang balance is broken** — if the chart has 6+ doors in the same Yin/Yang polarity, the energy is stagnant. **Fix:** Recalculate using the **alternative Ju Shu** (e.g., if you used the day stem, try the hour stem method). If the chart remains dead, switch from rotating to flying plate — the different star placements often unlock the reading. --- ## Essential Verification Checklist Before finalizing any Qi Men chart: 1. **Check the Dun direction** — is it aligned with the solar term? 2. **Verify the Ju Shu** — does it match the day stem? (Re-calculate manually if using software) 3. **Confirm the value star and value door** — are they in the correct palaces? 4. **Scan for the three qi (Yi, Bing, Ding)** — are they all present? If one is missing, the escape is incomplete. 5. **Check the empty palace (空亡)** — if the Hour Pillar’s stem falls in an empty palace, the reading is delayed or uncertain. **Bold conclusion:** The most common error among intermediate practitioners is **over-relying on software** without understanding the underlying rotation logic. Always hand-draw your first three charts per week to build muscle memory. --- ## Practical Example: Yin Dun 6 Ju, Rotating Plate - **Solar term:** Summer Solstice → Autumn Equinox (Yin Dun) - **Day stem:** Gui (癸) → Ju Shu = 6 (from lookup table) - **Hour stem:** Xin (辛) → Value door starts in Palace 6 **Placement:** - Yi in Palace 6, Bing in Palace 5 (assigned to Palace 2), Ding in Palace 4 - Stars: Peng in Palace 6 (value star), Ren in Palace 5→2, Chong in Palace 4... - Doors: Value door (Xin) in Palace 6, then backward: Palace 5→2 (Jing), Palace 4 (Si)... **Result:** The Yi, Bing, Ding are spread across Palaces 6, 2, and 4 — a strong triangular formation. This chart is "alive" and suitable for strategic planning. --- ## Final Integration
