Gui Mountain in the 24 Feng Shui Directions: Meaning and Interpretation

The Quý mountain in the 24 feng shui mountains: Meaning and how to interpret it

Where is the Quý mountain on the compass, and why can its position be derived rather than memorised?

The Quý mountain sits at roughly 7.5° to 22.5° on the compass ring, measured clockwise from true North, and it is the 2nd mountain among the 24. This position is not a number you have to memorise separately; it can be derived from two fixed rules of the 24-mountain system.

Rule one: the 360° compass ring is divided evenly among 24 mountains, so each mountain spans exactly 15°. Rule two: the mountain at the centre of each of the eight directions carries the name of that direction, meaning Tý at true North, Ngọ at true South, Mão at true East, Dậu at true West. The Tý mountain therefore occupies roughly 352.5° to 7.5°, with 0° as its centre.

From there, the next mountain clockwise is Quý, adding another 15°: 7.5° to 22.5°. The third mountain in the North direction is Nhâm, sitting at 337.5° to 352.5°, on the other side of Tý. Counting in this order, Quý is the 2nd mountain among the 24, and no table is needed to confirm it.

The 24 mountains are made up of 12 earthly branches, 8 heavenly stems and 4 trigrams Càn, Khôn, Cấn, Tốn. There are only 8 heavenly stems because Mậu and Kỷ both belong to Earth, corresponding to the central palace, and the central palace has no position on the compass ring. The four principal trigrams Khảm, Ly, Chấn, Đoài have no mountain bearing their name, because those four positions are already occupied by the four branches Tý, Ngọ, Mão, Dậu. The Quý mountain is a heavenly stem, and that explains why it falls into the Nhân nguyên long group, which will be set out in the fourth section.

Which palace does the Quý mountain belong to in the Later Heaven bagua, and which three mountains share that palace?

The Quý mountain belongs to the Khảm palace in the Later Heaven bagua. The three mountains sharing the Khảm palace, in the order Earth, Heaven, Human nguyên long, are Nhâm (Earth), Tý (Heaven), Quý (Human).

A distinction is needed between palace and direction. The North direction is one of the eight directions, spanning 45°, covering all three mountains Nhâm, Tý and Quý. The Khảm palace is one of the eight palaces of the Later Heaven bagua, and in compass usage the Khảm palace coincides with that same 45° band. Saying "the Quý mountain belongs to the North direction" and "the Quý mountain belongs to the Khảm palace" are two ways of naming the same position, but "direction" is a concept of orientation while "palace" is a concept of trigram. When interpreting Bát Trạch or Huyền Không, practitioners use palaces; when describing pure orientation, they use directions.

The central mountain of the North direction, that is the Heaven nguyên long, is Tý. This is the mountain carrying the name of the direction itself, sitting exactly at the 0° centre. So although Quý and Nhâm also belong to the Khảm palace, they are not the central mountain, and this has a direct consequence in the Tam Nguyên long section below.

One point to settle now to avoid confusion later: the Khảm palace is the only palace containing the Quý mountain. No division of the 24 mountains in feng shui assigns the Quý mountain to any other palace, because dividing the 24 mountains among eight palaces is a fixed geometric convention, not a place where schools interpret differently.

What is the Five Elements nature of the Quý mountain, and why are there two answers that do not contradict each other?

Considering the Five Elements of the heavenly stem that names the mountain, Quý belongs to Water, and is yin Water. Considering the Five Elements of the palace containing it on the Later Heaven compass, the Quý mountain lies in the Khảm palace, and the Khảm palace belongs to the Water element. These two statements do not contradict each other, and in the case of the Quý mountain they even coincide, but the mechanism is entirely different.

The first statement concerns the Five Elements assigned to the heavenly stem Quý within the ten-stem system. The second concerns the Five Elements of the Khảm trigram in the Later Heaven bagua. One belongs to the stem-branch system, the other to the trigram system. They happen to both be Water for this mountain, not because of the same reason.

This is exactly where many articles confuse readers. When a mountain has the two systems giving two different elements, for example a mountain carrying a Metal stem but lying in a Wood palace, an article that writes "this mountain belongs to Metal" in one paragraph and "this mountain belongs to Wood" in the next without stating the frame of reference will make readers think the article contradicts itself. In fact both are correct, each within its own system. The right way to write is always to state clearly: considering the Five Elements of the stem naming the mountain gives this result, considering the Five Elements of the palace containing it gives that result. With the Quý mountain, both systems give Water, so this is a comfortable case, but readers still need to know these are two independent calculations, not one calculation mentioned twice.

On yin and yang, the assignment for each mountain is not entirely consistent across Huyền Không branches. Some branches take yin and yang from the original stem-branch, others take it from the mountain's position within the palace. This article does not take sides, it only notes that this is a real point of disagreement, and readers should know which convention they are following before working with flying stars.

What is the Tam Nguyên long of the Quý mountain, and what does that mean when choosing mountain and facing?

The Quý mountain belongs to the Human nguyên long. Among the three mountains of the Khảm palace, Nhâm is the Earth nguyên long, Tý is the Heaven nguyên long, and Quý is the Human nguyên long.

The Tam Nguyên long classifies the 24 mountains by the origin of their names, and each type has its own rules when establishing a facing. The Earth nguyên long is tied to earthly branches and the four trigrams Càn, Khôn, Cấn, Tốn; the Heaven nguyên long is tied to the four principal branches Tý, Ngọ, Mão, Dậu; the Human nguyên long is tied to the remaining eight heavenly stems and the four branches Dần, Thân, Tỵ, Hợi. The Quý mountain is a heavenly stem, so it falls into the Human nguyên long, exactly according to this classification rule.

The practical meaning: the three mountains within one palace cannot substitute for one another when establishing a facing. If you choose Nhâm instead of Quý, you have shifted the facing centre by 15°, and the entire flying star chart, the mountain-facing relationship, and the forward or reverse yin-yang calculation all change accordingly. Being in the same Khảm palace does not mean the same result. Beginners often mistake this, assuming that sharing a palace means sharing an interpretation, and so they establish a facing that is off by an entire mountain.

It should be added that the Tam Nguyên long is not an independent system for choosing fortune or misfortune. It is a layer of classification used to decide the facing rules in Tam Nguyên schools. The three mountains within one palace cannot substitute for one another, not because one mountain is good and another bad, but because each mountain brings a different set of rules on yin and yang, on the relationship with the opposite mountain, and on how to place the facing centre.

Where does Bát Trạch place the Quý mountain, and what are the limits of that placement?

Bát Trạch places the Khảm palace, and therefore the Quý mountain, in the East Four Houses. The four palaces belonging to the East Four Houses are Khảm, Ly, Chấn, Tốn; the remaining four palaces Càn, Khôn, Cấn, Đoài belong to the West Four Houses.

A limit worth stating clearly: Bát Trạch works with the eight 45° directions and with a person's life palace, not with the 24 mountains of 15°. When Bát Trạch says "North direction", it groups Nhâm, Tý and Quý together. So at the Bát Trạch level, the Quý mountain has no separate role: it is simply part of the North direction. To distinguish Quý from Tý and Nhâm you have to go down to the 24-mountain level, that is, to Huyền Không or to schools that use a detailed compass.

It should also be added that Bát Trạch is used to match a life palace with a house direction, not to grade fortune or misfortune for each mountain. Any article that assigns the Quý mountain its own Bát Trạch star such as Sinh Khí or Thiên Y has mixed the levels: those stars belong to the relationship between the life palace and the direction, not to the mountain itself. In other words, there is no fixed "Bát Trạch star of the Quý mountain", because the Bát Trạch result depends on each person's life palace, not on the mountain's name.

How does Huyền Không flying stars use the Quý mountain, and where do the schools still disagree?

Huyền Không flying stars uses the Quý mountain at the 24-mountain level, specifically to determine the mountain centre of the sitting and facing, and from there to build the flying star chart for the period under consideration and calculate the star reaching the mountain and the star reaching the facing. The Quý mountain indicates that the sitting-facing of the structure lies in the 7.5° to 22.5° band, not at 352.5° to 7.5° as with the Tý mountain.

The point of disagreement among Huyền Không branches is how yin and yang are assigned to each mountain, and this assignment decides forward or reverse flying when placing stars into the mountain and into the facing. Some branches take yin and yang from the mountain's original stem-branch, others take it from the mountain's position within the palace. With the Quý mountain, these two methods can give different results, and therefore the flying star charts built also differ in flying direction. This article does not assert which side is correct, because this is a real disagreement among branches, and practitioners still use them in parallel.

One more point needs separating out: the 24-mountain level and the flying star level are two different levels. The Quý mountain determines position. Flying stars determine which star flies into that position according to the period. There is no such thing as the Quý mountain itself "carrying" a fixed star number. If an article writes "the Quý mountain corresponds to star X" without saying which period is under consideration, that statement lacks a frame of reference.

It should also be distinguished from a common confusion: the Quý mountain belongs to the Khảm palace, and the Khảm palace has trigram number 1 in Huyền Không. But trigram number 1 belongs to the palace, not to the mountain. The Quý mountain is not "number 1". It simply lies within the degree band belonging to the Khảm palace, and when building a chart the mountain centre is placed at 15°, the middle of the 7.5° to 22.5° band.

What is the measurement error when determining the Quý mountain, and what are the two adjacent mountains?

The Quý mountain spans only 15°, from 7.5° to 22.5°. The adjacent mountain below is Tý, occupying 352.5° to 7.5°. The adjacent mountain above is Sửu, occupying 22.5° to 37.5°.

The practical consequence: a deviation of only about 7.5° from the mountain centre already puts you in another mountain. If the measured sitting centre of a structure is 6°, it belongs to the Tý mountain, not the Quý mountain, even though they are only a few degrees apart. If it measures 24°, it has already moved into the Sửu mountain. At the 24-mountain level, this boundary is not a minor technical detail, it is the factor that decides the entire chart.

For this reason, when measuring with a compass, the needle should be placed at the true centre, interference from nearby metal and magnetic fields should be avoided, and measurements should be repeated at several points. For structures sitting close to the 7.5° or 22.5° line, practitioners often record both possibilities and interpret both, rather than locking in a single mountain.

The opposite mountain of Quý through the compass centre is Đinh, lying in the South direction, in the Ly palace. The pair Quý and Đinh are exactly 180° apart, and this is a sitting-facing pair often encountered when a structure faces South. Note that Đinh is also a heavenly stem, belonging to the Human nguyên long, lying in the Ly palace. The central mountain of the South direction is Ngọ, corresponding to Tý in the North direction.

Which parts of this article are cultural knowledge rather than prediction?

The entire portion on degree positions, the Khảm palace, the Tam Nguyên long, the East Four Houses classification, and the symmetrical relationship between Quý and Đinh is structural knowledge of the 24-mountain system. These are geometric and classificatory conventions, verifiable by counting on the compass ring, not predictions about human life.

The portion interpreting fortune and misfortune according to Huyền Không, Bát Trạch or Tam Hợp is cultural interpretation, systematic and with a history, but not scientific prediction. Conclusions of the kind "a house sitting on this mountain will receive blessings" or "will lose wealth" should not be read as promises or certain warnings. Feng shui here is a knowledge tradition and a way of organising space according to ancient conceptions, not a substitute for decisions about finance, health or legal matters.

Even the numbers in this article, such as 7.5° or 22.5°, only have meaning within the frame of reference of the 24-mountain compass. They are not physical constants, not measurable with modern instruments the way temperature or mass is measured, but a convention for dividing a circle belonging to one tradition. Readers should take this article as a conceptual map, not a results look-up table.
