Qi Men Dun Jia 8 Doors Explained: 八门 Palaces and Use

The eight doors in one table

Every door has a home palace, and from the palace it inherits a direction, a trigram and an element. The palace assignments and the auspice classes below are the ones our Qi Men engine uses; the uses are the classical ones.

Palace 5, the centre, has no door of its own. That is not a gap in the table: the doors belong to the eight trigrams, and the centre is not a trigram.

The three auspicious doors: Open, Rest and Life

Open (开门) is the Metal door of the Qian palace in the Northwest — the "heaven gate". It favours official and public action: opening a business, starting a role, signing formal agreements, dealing with institutions. Where a plan needs a door to be opened by someone with authority, the Open Door is the one to look for. Our Open Door guide goes further.

Rest (休门) is the Water door of the Kan palace in the North. Its name is literal: rest, recovery, restoration. It also favours the quiet side of business — negotiation off the record, meeting a patron, accumulating slowly without drawing attention. See the Rest Door guide.

Life (生门) is the Earth door of the Gen palace in the Northeast, and the most consistently auspicious of the eight. 生 means birth, life and growth, and the door was used for anything meant to compound: new ventures, property, the foundation of a long project. See the Life Door guide.

The three difficult doors, and what they are for

The difficult doors are the most misread part of the system. The classification describes what an ordinary intention — a launch, a wedding, a first meeting — meets there. It does not mean the door is useless.

Injury (伤门) is the Wood door of the Zhen palace in the East, thunder. It is the door of chosen confrontation: pressing a claim, collecting what is owed, competing. For a peace talk it is the wrong door; for a contest you have decided to win it is the right one. See the Injury Door guide.

Death (死门) is the Earth door of the Kun palace in the Southwest. It is the door of endings, and classical practice used it for exactly that — closing things down, demolitions, funerals, hunting. It is the last door you would choose for a beginning, which is the whole of its meaning. See the Death Door guide.

Shock (惊门) is the Metal door of the Dui palace in the West. It is the door of alarm and argument: litigation, debate, and deliberately unsettling an opponent's composure. Note the character — 惊 jīng, first tone — which is a different word from the Scenery Door's 景 jǐng. See the Shock Door guide.

The two doors in between: Block and Scenery

Block (杜门) is the Wood door of the Xun palace in the Southeast. 杜 means to stop up. It favours concealment, retreat, secrecy and closing gaps — the moment to protect something rather than show it. Our engine classes Block as neutral. Some lineages count it among four inauspicious doors (Injury, Block, Death and Shock) rather than three; the difference is one of classification, not of what the door is for. See the Block Door guide.

Scenery (景门) is the Fire door of the Li palace in the South. It is the door of visibility: announcements, publicity, examinations, documents, anything whose point is to be seen. That is why it is neutral rather than good — being seen is exactly what you do not want in some situations. See the Scenery Door guide.

How the doors move, and the Duty Door

The table shows where each door lives. In a chart, the doors leave home. Every two-hour window the chart is cast again, and where each door lands depends on the hour, the day and the structure of the current solar term. That is why a door reading is always for a particular two-hour window and a particular direction.

One door leads each window: the Duty Door (值使, zhí shǐ), paired with the Duty Star (值符). It is the door whose home palace is the Duty Star's home palace. When that palace is the centre, which has no door, the door of Kun — the Death Door — stands in, the same rule by which the centre's star is lodged in Kun. Reading the Duty Door first gives the character of the whole window before you look at any single direction.

Door against palace: door compulsion

The classical refinement every serious reading adds is door compulsion (门迫, mén pò). A door carries its home element wherever it lands. When that element overcomes the element of the palace it lands in, the door is said to be compelled, and the classical line is blunt: an auspicious door under compulsion does not deliver its good, and a difficult door under compulsion gets worse.

The cases follow directly from the controlling cycle of the five elements — Water over Fire, Fire over Metal, Metal over Wood, Wood over Earth, Earth over Water:

• Open and Shock (Metal) are compelled in the Wood palaces, 3 and 4.
• Injury and Block (Wood) are compelled in the Earth palaces, 2 and 8 — and in the centre, which is also Earth, when a Flying Plate chart puts a door there.
• Rest (Water) is compelled in the Fire palace, 9.
• Scenery (Fire) is compelled in the Metal palaces, 6 and 7.
• Life and Death (Earth) are compelled in the Water palace, 1.

So an Open Door in the East is a weaker Open Door than one in the West, even though both are auspicious on paper.

Reading a door in practice

1. Name the action. Starting, resting, confronting, hiding, being seen, ending. Match it to the door whose use it is.
2. Find the direction and the window. Pull up the chart for the two-hour window you are acting in and find the palace for the direction that matters — where you are going, where the other party is, where the thing happens.
3. Read the door with its neighbours. Check the door for compulsion, then read it together with the star and the deity in the same palace. We explain why the four-part reading matters in classical Qi Men versus modern apps.

The Qi Men hour chart casts the current window with every door, star and deity in place, so you can run these three steps on a real chart. The doors do not tell you whether to act. They tell you which kind of action the moment is built for.

For reflection, education and entertainment. Qi Men Dun Jia is a traditional timing system, not a prediction of outcomes.
