What Is Qi Men Dunjia? A Beginner's Guide

At heart, Qi Men Dunjia (奇門遁甲) draws the energy distribution of a single point in time as a nine-palace directional chart.

Take the three characters one at a time:

• Qi (奇): the Three Wonders — Yi, Bing and Ding, the three most flexible stems in the chart. The Three Wonders are generally auspicious, but good or bad fortune must still be judged together with the formation, the door, star and deity, and the productive/controlling relations with the palace.
• Men (門): the Eight Doors — Rest, Life, Injury, Delusion, Scenery, Death, Fright and Open, representing the kind of human activity suited to that palace.
• Dun Jia (遁甲): Jia is the commander. It never appears directly, but hides beneath the Six Instruments (Wu, Ji, Geng, Xin, Ren, Gui). Part of reading a chart is knowing where the commander is hiding.

Put together: in this hour, what is the state of each of the nine directions, and which direction supports what you want to do.

This course does not teach hand-plotting. Cast your chart with NPCC's Qi Men charting tools and spend your time on reading the chart.

Traditionally Qi Men Dunjia is attributed to military legends such as the Yellow Emperor, Jiang Ziya and Zhuge Liang, and is named alongside Tai Yi and Liu Ren as one of the "Three Styles" (三式). These attributions are legend rather than verifiable history; the surviving literature can be traced through several lines of transmission, chiefly the introductory verse primer Yan Bo Diao Sou Ge (煙波釣叟歌), as well as compendia such as Qi Men Dun Jia Tong Zong (奇門遁甲統宗) and the Qing imperially commissioned Yu Ding Qi Men Bao Jian (御定奇門寶鑑).

Beginners usually meet the Yan Bo Diao Sou Ge first, because it compresses the structural rules into rhymed lines, for example: 陰陽順逆妙難窮，二至還鄉一九宮 — "the forward and reverse motion of yin and yang is subtle beyond exhausting; at the two solstices it returns home to Palace One and Palace Nine." That line describes exactly the alternation between yang dun and yin dun forward/reverse counting through the year, and the starting bureau points: the winter solstice starts at Palace One, the summer solstice at Palace Nine.

Every Qi Men chart has the same layers. Learn the layers first, and the later lessons are just filling in content.

Note: the Eight Deities listed above are the set used in hour-based rotating plate; other schools (such as flying plate) often use Gou Chen and Zhu Que in place of Bai Hu and Xuan Wu.

The order for reading a palace: palace and direction → Earth Plate stem → Heaven Plate stem → star → door → deity.

Suppose your question is: "Is this afternoon suitable for pitching to the client, and in which direction should I negotiate?" Cast an hour chart and look at the palace representing the client.

The combination below is a symbolic illustration only, used to demonstrate the reading order; it is not validated against rotating-plate rules and is not an actual charting result. In a real chart the Heaven Plate stems must be arranged according to the leading stem of the decade (xun shou) and the hour stem, and cannot be assigned arbitrarily.

Say that palace is Palace Six (Qian, northwest), containing:

• Nine Stars: Heavenly Heart Star (Tian Xin) — clarity, strategy, good remedies.
• Eight Doors: Open Door (Kai Men) — opening up, official and formal dealings, starting things.
• Eight Deities: Chief Deity (Zhi Fu) — the person in charge, authority in place.

Read in order: the arena is the northwest, governing authority and senior decision-makers; Tian Xin, the Open Door and the Qian palace all belong to metal, so metal qi is strong, favouring clear counsel and formal openings — but soft persuasive power is restrained. If the use-deity (yong shen) is the Yi Wonder, strong metal controls Yi and the Yi Wonder is restrained, so it should be remedied with thorough preparation, a written proposal and formal procedure, rather than relying on gentle words alone or on forcing the matter. Zhi Fu can be read as a symbol that authority or decision-making leadership is involved in the matter — whether such a person is actually present still has to be confirmed in reality. Overall this reads as: you may go northwest and follow formal procedure, but with the Yi Wonder restrained you should not rely on words alone; prepare a written proposal, set the goal as advancing the matter rather than signing, and lower your expectations.

Note what it does not say: it does not guarantee a signed contract. It describes conditions, and conditions are something you can work with.

Bazi and Zi Wei Dou Shu start from the birth moment and describe a person: temperament, strength and weakness, life structure, major and annual cycles. They answer "who am I, and what phase am I in now?"

Qi Men Dunjia starts from "the moment of the question or the action" and answers "what is the shape of this matter now, which hour and which direction are favourable, and where is the leverage?" So it is a planning and date-selection instrument, not a verdict on fate.

Two main uses:

• Hour-based Qi Men (shi jia): the mainstream practical route, and what NPCC teaches. Cast a chart for the present or a planned hour and read it for a specific matter — negotiation, travel, hiring, opening a business, finding lost objects.
• Natal Qi Men (ben ming): casting from the birth moment to look at character and life themes. It is a legitimate branch, but it overlaps in function with Bazi and is not the focus of this course.

Hour-based Qi Men can be applied directly to present decisions; whether it is of greater practical benefit varies from person to person.

Two different charts for the same hour is a normal phenomenon: it is a matter of method, not of right and wrong.

• Rotating plate vs flying plate: rotating-plate schools rotate the Heaven Plate as a whole set; flying-plate schools distribute each element palace by palace in the Luo Shu order. Both have long lineages. NPCC uses hour-based rotating plate.
• Chai Bu vs Zhi Run: two ways of handling "fixing the bureau" when the solar terms and the sixty-jiazi cycle do not align; near a solar term boundary they produce different bureaus.
• Ji Gong (lodging): Palace Five has no trigram, so its contents must lodge in another palace — generally Palace Two, though some lineages differ according to yang dun or yin dun charts. Schools disagree on this point.
• Names of the Eight Deities: the roster of the Eight Deities also differs by school. Hour-based rotating plate uses Bai Hu and Xuan Wu, while some schools use Gou Chen and Zhu Que.

Pick one system and stay in it. Mixing rules from two schools is the fastest way to read noise.

• Treating it as predetermined fate. The chart speaks of the conditions of a matter within a period of time. An inauspicious sign means "expect friction, prepare in advance," not that the outcome is fixed.
• Reading a single symbol alone. The Death Door (Si Men) does not by itself equal disaster; with suitable stems and deities it can indicate closing a case, settling matters, or handling old business. Always read palace, stems, star, door and deity together.
• Asking too vaguely. When a question is too general the use-deity is hard to fix and the reading easily loses focus; reframe it as a concrete matter within a time range, such as "Should I sign on Thursday or wait until next week?"
• Re-casting until you are satisfied. One question, one chart, one honest reading.
• Expecting what it cannot do. Qi Men excels at selecting timing, fixing direction and finding the point of leverage; it cannot replace professional medical, legal or financial advice.
