TL;DR: Wei Mountain is one of the 24 mountain directions, located in the Xin Wei palace (southwest corner), belonging to the Earth element and the Kun trigram. It symbolizes stability, nurturing, and accumulation, but careful consideration of its combination with the opposing Chou direction and temporal/spatial factors is essential for accurate interpretation.
What is the 24 Mountain Directions system and where does the Mùi mountain sit?
The 24 Mountain Directions system is the core foundation of Landscape Feng Shui, used to determine the precise orientation of houses, graves, and architectural works. Unlike the simple 8-direction system (Bát Trạch) which only divides the compass into 8 equal parts of 45 degrees each, the 24-mountain system divides the compass ring into 24 parts of 15 degrees each. This detail allows feng shui practitioners to analyze more subtly the influence of geomagnetic fields and qi fields on living spaces.
Among the 24 mountains, each mountain is named after one of three symbol systems: Heavenly Stems (Giáp, Ất, Bính, Đinh, Canh, Tân, Nhâm, Quý), Earthly Branches (Tý, Sửu, Dần, Mão, Thìn, Tỵ, Ngọ, Mùi, Thân, Dậu, Tuất, Hợi), and the Eight Trigrams (Càn, Khôn, Tốn, Cấn). The Mùi mountain belongs to the Earthly Branch group, located at the precise position from 202.5 degrees to 217.5 degrees on the feng shui compass, measured clockwise from North (0 degrees). The center of the Mùi mountain sits at 210 degrees, belonging to the Tân Mùi palace in the 60 hoa giáp system.
Geographically, the Mùi mountain lies at the Southwest corner of the compass, between the Đinh mountain (South-Southwest) and the Khôn mountain (West-Southwest). In relation to other mountains, the Mùi mountain opposes the Sửu mountain (located at the Northeast corner, from 22.5 to 37.5 degrees). This opposition creates an important energy axis, affecting how interpretations are made when the Mùi mountain appears in a structure.
What are the basic attributes of the Mùi mountain?
What are the Five Elements and trigram destiny of the Mùi mountain?
The Mùi mountain belongs to the Earth element, specifically yin Earth. In Five Elements theory, Earth represents stability, centrality, the capacity to nourish and shelter. Earth is the origin of all things, the mother of metal, the place to which all things return after a cycle ends. Therefore, the Mùi mountain carries the energy of accumulation, preservation, and transformation.
The Mùi mountain lies within the Khôn trigram (☷), a pure yin trigram, symbolizing mother earth, compliance, nurturing, and tolerance. The Khôn trigram in the I Ching is described as "The earth's condition is Khôn, the gentleman thereby carries all things with thick virtue" (thick earth, the gentleman uses thick virtue to shelter all things). This shows that the Mùi mountain relates to the qualities of a mother, patience, tolerance, and the capacity to endure.
How does the Mùi mountain relate to other factors?
In the Stem-Branch system, Mùi is the 8th branch among the 12 Earthly Branches, belonging to the Three Harmony group with Hợi and Mão (the Wood frame group). This creates a special connection: although Mùi belongs to Earth, it sits within the Wood three-harmony, so when combined with Hợi and Mão it forms a Wood frame, carrying the energy of growth and development. Meanwhile, Mùi clashes with Sửu (the 2nd branch), and Sửu also belongs to Earth. Two Earths clashing create stagnation and congestion if not resolved.
In terms of direction, the Mùi mountain belongs to the Khôn palace of the Later Heaven Eight Trigrams. The Khôn palace in the Later Heaven sits at the Southwest, corresponding to the 7th and 8th lunar months (early autumn), the time when yin qi begins to rise after the yang peak of summer. Therefore, the Mùi mountain is tied to a transitional period, a time of harvest and preparation for rest.
How do you determine and apply the Mùi mountain in practice?
How are measurements and mountain-direction determinations made?
To determine whether a structure belongs to the Mùi mountain, people use a feng shui compass (la kinh) with high precision. Measurements need to be taken at the center of the house, avoiding magnetized objects such as phones, watches, and large metal frames. When the compass needle points to roughly 202.5 to 217.5 degrees, that structure is determined to belong to the Mùi mountain.
However, in feng shui, people usually determine both the mountain and the direction. The mountain is the position behind the house (the backing), the direction is the position in front of the house (the facing). A house "sitting Mùi facing Sửu" means the back of the house lies at the Mùi direction (Southwest), while the front faces the Sửu direction (Northeast). Conversely, "sitting Sửu facing Mùi" is a house backed to the Northeast and facing the Southwest.
How is the Mùi mountain distinguished from neighboring mountains?
| Mountain | Degree range |
|---|---|
| Đinh | 187.5 to 202.5 degrees |
| Mùi | 202.5 to 217.5 degrees |
| Khôn | 217.5 to 232.5 degrees |
The boundary between these mountains is very thin, only 15 degrees, so even a small measurement error can lead to identifying the wrong mountain. In practice, if the house center leans toward the Khôn mountain, the arrangement and interpretation will be completely different from the Mùi mountain. Because of this complexity, the ancients had a saying, "off by one inch, away by one mile," to emphasize the importance of precise measurement.
What does the Mùi mountain mean in different feng shui schools?
The Bát Trạch school (destiny and dwelling)
In Bát Trạch, the Mùi mountain belongs to the Khôn palace, one of the Tứ Trạch (the directions belonging to the West Four Dwellings: Càn, Khôn, Cấn, Đoài). According to this school, a house sitting Mùi or facing Mùi belongs to the West Four Dwellings, suitable for people whose destiny belongs to the West Four Destinies (the Khôn, Càn, Cấn, Đoài palaces in the Bát Trạch Minh Kính). Specifically, people born in the Khôn palace (usually those with trigram number 2) are considered compatible with a house sitting Mùi facing Sửu.
However, Bát Trạch does not consider the mountain alone but also the 8 major directions. For a house facing Mùi (that is, looking Southwest), good and bad directions are determined based on the sitting mountain. The good directions including Sinh Khí, Thiên Y, Diên Niên, Phục Vị, and the bad directions including Tuyệt Mệnh, Ngũ Quỷ, Lục Sát, Họa Hại will be calculated based on the position of the sitting mountain.
The Huyền Không Phi Tinh school
In Huyền Không, the Mùi mountain is interpreted based on period qi and the combination of mountain stars and direction stars. Each period (20 years) has a different governing star, and the Mùi mountain receives different stars through each period. For example, in period 8 (2004-2023), the Mùi mountain receives star 3 (Tam Bích, Wood star) as mountain star and star 2 (Nhị Hắc, Earth star) as direction star in certain combinations. The combination of star 3 Wood and star 2 Earth can create a Wood overcoming Earth configuration, which needs careful consideration.
A Huyền Không interpreter will examine the Mùi mountain in relation to current and future period qi. The Mùi mountain belongs to the Earth element, so when meeting stars of the Fire element (star 9 Tử Vi, star 7 Phá Quân in some cases) it will be supported, and when meeting stars of the Wood element (star 3, star 4) it will be suppressed. In addition, one needs to consider whether each star is prosperous or declining for an accurate interpretation.
The Loan Đầu school (landform)
In terms of Loan Đầu, the Mùi mountain belongs to the gentle side of Earth mountains, preferring rounded mountain forms, flat land, and yellow or brown colors. If behind the house (sitting Mùi) there is a mountain or a moderately tall structure shaped like a reclining nghê or elephant, it is considered good. Conversely, if there are jagged rocky mountains, steep terrain, or objects with fierce shapes, it will not be good for this mountain.
With the Mùi direction (looking Southwest), the place receiving qi should have water (river, lake, road) but it must not be too urgent or fast-flowing. Water meeting an Earth mountain needs to be gentle and winding, symbolizing the gradual accumulation of wealth. If the water is too strong, washing straight into the house direction, it can cause loss and difficulty in keeping wealth.
What mountain-direction combinations involve the Mùi mountain?
What does sitting Mùi facing Sửu mean?
This is the most common combination when mentioning the Mùi mountain. A house sitting Mùi facing Sửu means backing to the Southwest and looking to the Northeast. In feng shui, this combination belongs to the West Four Dwellings and is usually interpreted as having stability at the foundation level, suitable for families seeking sustainability and long-term endurance. However, because Sửu and Mùi clash, special attention must be paid to resolving this clash by creating a winding configuration, screening, or using suitable feng shui objects.
What does sitting Sửu facing Mùi mean?
Opposite to the above combination, a house sitting Sửu facing Mùi backs to the Northeast and looks to the Southwest. The Mùi direction in this combination receives qi from the Southwest, where the Khôn trigram sits. Qi coming from this direction carries a yin, gentle nature, beneficial for family relationships and careers in education, caregiving, and the arts. However, one needs to consider whether the water configuration in front is reasonable to assess the degree of good or bad.
Other combinations in the 120 phân kim
In the 120 phân kim system (dividing each mountain into 5 phân kim, each 3 degrees), the Mùi mountain has 5 phân kim:
| Phân kim | Five Elements |
|---|---|
| Ất Mùi | Metal |
| Đinh Mùi | Water |
| Kỷ Mùi | Fire |
| Tân Mùi | Earth |
| Quý Mùi | Wood |
Each phân kim carries a different element, creating variations in interpretation. Among them, Tân Mùi is usually considered the most prosperous phân kim because pure Earth is compatible with the inherent qi of the mountain, while Kỷ Mùi (Fire), although it generates Earth, requires considering the prosperity or decline of Fire in each period.
How do you apply the Mùi mountain in practice?
In choosing house direction
When considering a plot of land or a house with the Mùi mountain, people do not simply examine the Mùi mountain but also the overall factors: sitting mountain, direction, water mouth, dragon vein, and annual periods. The Mùi mountain belongs to Earth, so people with Fire destiny (since Fire generates Earth) or Earth destiny are usually considered most compatible. People with Wood destiny need caution because Wood overcomes Earth, and may encounter many obstacles in bringing out the positive energy of this mountain.
In interior arrangement
For a house belonging to the Mùi mountain, the Southwest area (Khôn palace) needs attention. This is the area representing motherhood, the woman in the family, and care. This area should be kept clean and open, and one can use objects of the Fire element (lamps, candles, red and orange colors) to support Earth, or objects of the Earth element (ceramics, brown and earth-yellow crystal) to strengthen the energy. Avoid placing too many green plants (Wood element) or objects of the Wood element in this area because Wood overcomes Earth, causing weakening.
Notes on timing and fortune cycles
According to feng shui, each mountain direction has prosperous years and declining years. The Mùi mountain belongs to the three-harmony with Hợi and Mão, so the years Hợi, Mão, and Mùi are usually considered to have more prosperous qi for structures carrying the Mùi mountain. Conversely, the year Sửu (clashing with Mùi) and years with overly prosperous Wood element can create disadvantage. However, it must be emphasized that these interpretations are only relative, depending greatly on the specific context of each house, each plot of land, and each family.
