What is Qi Men Dun Jia?
Overview
Qi Men Dun Jia (奇门遁甲) is one of the highest-level divination systems in ancient China, collectively known as the "Three Styles" (三式) alongside Tai Yi Shen Shu (太乙神数) and Da Liu Ren (大六壬), and regarded as the foremost of the three. It is not merely a divination technique, but a comprehensive spatiotemporal decision-making model integrating I Ching (易经), astronomical calendars, Yin-Yang & Five Elements (阴阳五行), military strategy, and philosophy.
Legendary Origins
Legend has it that during the Battle of Zhuolu, when Chi You created a great fog that disoriented the Yellow Emperor's army, the Nine Heavens Profound Girl (九天玄女) descended and bestowed the "Dragon Armor Divine Chapter" (龙甲神章). The Yellow Emperor's minister Feng Hou then derived 1,080 QMDJ configurations from it. While not historically verified, this legend reflects QMDJ's deep connection to military strategy and spatial navigation.
Historical Evolution
QMDJ underwent three major simplifications: Jiang Tai Gong of the Zhou Dynasty compressed 1,080 configurations into 72; Zhang Liang of the Han Dynasty further reformed it into 18 configurations (9 Yin Retreat + 9 Yang Retreat), which remain the foundation today; during the Tang and Song Dynasties, the system matured with official adoption by the Imperial Astronomy Bureau.
Structure
QMDJ consists of three parts: Three Wonders (三奇: 乙, 丙, 丁) symbolizing the Three Realms; Eight Doors (八门: 休, 生, 伤, 杜, 景, 死, 惊, 开) representing all human affairs; and Dun Jia (遁甲), which conceals the celestial stem 甲 beneath the Six Instruments (六仪). 九星 (Nine Stars) and 八神 (Eight Spirits) complete the spatiotemporal model.
Our Philosophy
Against superstition, respecting science. QMDJ is not fortune-telling, nor feudal superstition. It is a spatiotemporal strategic model distilled over thousands of years — revealing that under specific spacetime conditions, all things follow observable patterns. We use AI technology to reinterpret this cultural heritage, enabling more people to understand and apply it rationally.
Destiny is self-created, fortune is self-sought.
Know your fate but never resign to it — that is the true wisdom of QMDJ.
Nine Palaces & Directions

In Qi Men Dun Jia, the Eight Doors represent the human dimension — they govern all affairs, choices, and activities of people.

Legendary Masters of QMDJ
The Strategists Who Changed History
Throughout Chinese history, Qi Men Dun Jia was the secret weapon of brilliant strategists — from the founding of dynasties to decisive battles that shaped civilizations. These legendary figures elevated QMDJ from a divination art to a tool of statecraft and military genius.
The most celebrated QMDJ practitioner in history. His legendary "Borrowing the East Wind" (借东风) at the Battle of Red Cliffs — using QMDJ to predict a shift in wind direction — turned the tide against Cao Cao's massive fleet. His "Eight Array Maze" (八阵图) trapped enemy forces using QMDJ spatial principles. Known as the "Sleeping Dragon," he remains the symbol of strategic brilliance.
Founding military strategist of the Ming Dynasty and author of comprehensive QMDJ manuals. His most famous application was at the Battle of Poyang Lake (1363 AD), where he used QMDJ to time a devastating fire attack against Chen Youliang's fleet of 600,000 troops — a victory that led to the founding of the Ming Empire. Often compared to Zhuge Liang as "the Liu Bowen of his era."
The legendary sage who helped King Wu overthrow the Shang Dynasty. Credited with simplifying QMDJ from 1,080 to 72 configurations, making the system more practical for military use. His treatise Liu Tao (六韬) integrates QMDJ principles into comprehensive military strategy. He is revered as the "Grandmaster of All Strategists."
The "Marquis of Liu" who helped Liu Bang found the Han Dynasty. He further refined QMDJ from 72 to 18 configurations (9 Yin + 9 Yang Retreat), which remains the foundation of the system today. His strategic genius at the Battle of Gaixia led to the defeat of Xiang Yu and the birth of the Han Empire.
QMDJ in the Modern World
From Ancient Battlefields to Boardrooms
Business Strategy
Timing product launches, negotiations, and investment decisions. In traditional QMDJ, the Open Door (开门) governs career and enterprise, while the Life Door (生门) indicates profit potential.
Date Selection
Choosing auspicious dates for weddings, grand openings, and major life events. QMDJ's 18 configurations map to specific time windows for optimal outcomes.
Feng Shui Analysis
While Feng Shui analyzes fixed spatial energy, QMDJ adds the temporal dimension — revealing when specific directions become favorable or unfavorable. Together, they form a complete spatial-temporal system.
Strategic Decision-Making
QMDJ's core principle — distinguishing Host (主) from Guest (客) — applies directly to modern competitive strategy: when to act first, when to respond, when to advance, when to retreat.
