A Door Is Only Half the Story门的吉凶，只是一半

Each of the eight doors carries a fixed reputation — the Open Door is auspicious, the Death Door grim, and so on down the list you'll find in which doors and stars are lucky. But that reputation is only a starting price. The instant a door lands in a palace, the five elements between the two renegotiate it: the palace can lift the door, hold it in check, or grind against it. Classical Qimen calls this negotiation the door's response (八门克应), and it turns four fixed relationships, each of them a five-element move between door and palace.

八门各有固定的名声——开门吉、死门凶，一路排下去，就是《哪些门和星是吉的》里那张表。可这名声只是个"标价"。门一落进某个宫，门与宫之间的五行立刻就把它重新议了价：宫可以抬举这扇门、可以按住它，也可以和它硬磨。经典奇门把这场"议价"称作八门克应，归结为四种固定关系，每一种都是门与宫之间的一次五行动作。

Every door carries an element — the element of its home palace, where it sits on a still chart. Open and Fright are metal (from 乾 and 兑); Rest is water; Life and Death are earth; Harm and Block are wood; Scenery is fire. Every palace has a fixed element too: water in the north (坎), fire in the south (离), wood in the east (震, 巽), metal in the west (乾, 兑), earth at the corners and center. So when a door leaves home and lands in some other palace, you simply compare the two elements — and only four things can happen.

每扇门都带着一种五行——就是它本宫的五行，它在静盘上归属的那个宫。开门、惊门属金（出自乾、兑）；休门属水；生门、死门属土；伤门、杜门属木；景门属火。每个宫也有固定的五行：北坎属水、南离属火、东方震巽属木、西方乾兑属金，四角与中宫属土。所以当一扇门离开本宫、落进别的宫，你只需把两个五行一比——就只可能发生四件事。

Take the Death Door. It belongs in 坤, an earth palace, so it is an earth door. Drop it into 坎, the water palace in the north, and earth controls water (土克水): the door attacks the very palace it's standing on. That is pressure (迫). Reverse the attack, and you get control; swap attack for generation, and you get harmony or support. The four have names — pressure (迫), control (制), harmony (和), support (义) — and knowing which one you're looking at tells you whether the door's headline meaning lands in full, comes out muffled, or turns against itself.

拿死门举例。它本属土宫坤，所以是一扇土门。把它落进北方的水宫坎，土克水：门就克了它脚下所站的那个宫。这就是门迫。把这个"克"反过来，就是"制"；把"克"换成"生"，就是"和"或"义"。四种各有其名——迫、制、和、义——认出你面前是哪一种，就知道这扇门的"标价含义"，是会足额兑现、会被捂住半分，还是会反过来伤到自己。

The Four Relations at a Glance四种关系，一眼看全

Read the grid below as door-versus-palace. The two on the left both turn on control (克) — in one the door controls the palace, in the other the palace controls the door; the two on the right both turn on generation (生) — in one the door generates the palace, in the other the palace generates the door. To see all four at once, the examples below follow a single door — the metal Open Door — into four different palaces, so you can watch one door meet four fates. By outcome: a lucky door does well with harmony or support and underdelivers under pressure, while an unlucky door is calmed by control and made worse by pressure.

下面这张图，读作"门 对 宫"。左边两种都属克——一种是门克宫，一种是宫克门；右边两种都属生——一种是门生宫，一种是宫生门。为把四种一次看全，下面的例子都跟着同一扇门——属金的开门——走进四个不同的宫，让你看清一扇门如何遇上四种命运。就结果而言：吉门遇和或义则顺、遇迫则吉不就；凶门遇制反倒凶不起来、遇迫则凶上加凶。

Pressure (Door Pressure): Forcing It门迫：逆地形硬推

Of the four, pressure is the one that turns into a warning flag. When the door's element controls the palace's — a wood door on an earth palace, a fire door on a metal palace — the door is "pressed": it can only deliver its promise by force, against the grain of the ground it stands on. The classical rhyme is blunt about the result. Because a pressed palace is also one of the chart's Four Harms, the full list of which doors press which palaces — and what to do about it — lives in that article; here it's enough to place pressure as the harshest of the four relations.

四种关系里，唯有"迫"会变成一面警旗。当门的五行克宫的五行——木门落土宫、火门落金宫——门便"被迫"：它只能强行兑现承诺，逆着脚下这片地的纹理。古歌诀对结果说得很直。由于被迫之宫同时也是盘上的四害之一，"哪些门迫哪些宫、见迫怎么办"的完整清单在那篇里；这里只需把"迫"摆在四种关系里最凶的位置。

Control, Harmony & Support: the Other Three制、和、义：另外三种

Control (制): the palace controls the door. This is pressure's mirror, and much gentler. A lucky door under control loses some of its shine — held back, it can't give its full good. But turn it around: an unlucky door under control is a genuinely useful thing. The palace pins it down, and its harm never gets off the ground. When you want to blunt a difficult door, control is exactly what you hope to see.

门制：宫克门。这是"迫"的镜像，却温和得多。吉门受制，会失几分光彩——被按着，好处使不全。但反过来看：凶门受制，是件实实在在的好事。宫把它钉住，凶气始终起不来。当你想钝化一扇难缠的门，"制"正是你盼着见到的。

Harmony (和): the door generates the palace. Here the door feeds the palace it sits in, moving with the terrain rather than against it. With a lucky door, this is the smoothest reading on the board — cooperation, momentum, things falling into place. Support (义): the palace generates the door. The direction reverses: now the palace resources the door, backing it and supplying it. A lucky door with support is well-provisioned and dependable — less spectacular than harmony, perhaps, but steady. Both are "generating" relations, and both lift a good door rather than draining it.

门和：门生宫。这里门生养着它所落的宫，顺地形走、不逆着来。配上吉门，这是全盘最顺的一种读法——彼此配合、有势头、事情各归其位。门义：宫生门。方向掉过来：现在是宫在供给这扇门，为它撑腰、给养。得吉门而有"义"，则供给充足、可靠——也许不如"和"那样耀眼，却胜在稳。两者都属"生"，都会把一扇好门抬起来，而不是泄它的气。

In Practice: One Question at the Door实战：见门先问一句

So the working habit is small but decisive. When a door matters to your question — the door on your key palace — don't stop at its headline meaning. Ask one more thing: what is the five-element relation between this door and the palace it sits in? Feed (和 / 义) and a good door delivers in full; control (制) and a bad door is safely muffled; pressure (迫) and even a lucky door is working uphill. The door names the action; the relation tells you how much of it actually happens.

所以那个实战习惯很小，却很关键。当一扇门对你的问题要紧时——落在你关键宫上的那扇门——别停在它的"标价含义"上。再多问一句：这扇门与它所落的宫，是什么五行关系？被"生"（和／义），好门足额兑现；被"制"，坏门被安稳地捂住；被"迫"，连吉门也是在逆水行舟。门，点出的是那个动作；关系，才告诉你这个动作真正能兑现几成。
