The Mountain-Fire Pig
乙亥 (Yi-Hai) · 山头火 (Mountain-Fire) · Wood Stem
The Mountain-Fire Pig defines those born in 1935 and 1995 under the Yi-Hai (乙亥) pillar. While mainstream astrology often classifies this year as the Wood Pig based on its Heavenly Stem (乙 = Wood), its deeper NaYin (纳音) resonance is Mountain-Fire (山头火) — blending wood’s core energy with fire’s expressive quality. This combination blends the Pig’s innate generosity with fire’s passion and charisma, creating natural leaders who inspire others. However, their impulsive nature and quick-burning energy mirror the NaYin’s image of fire atop a peak—brilliantly illuminating all yet prone to burning out fast.
A quick map: this is a Wood year by its Heavenly Stem (乙 / Yi), while its NaYin is Mountain-Fire (山头火), a Fire archetype — two parallel systems describing the same pillar, not a contradiction.

The Mountain-Fire Pig burns with a warmth visible to everyone, combining the Pig’s natural generosity with a radiant charisma that draws people in. They excel in community organizing, where their sincere enthusiasm ignites collective action. Their fire is both inspiring and nourishing—they throw themselves into causes with wholehearted joy, making others feel valued and motivated. This pig doesn’t just enjoy life; they illuminate the path for others to enjoy it too, creating vibrant networks wherever they go.
But this fire atop the mountain can also burn out quickly. The Mountain-Fire Pig’s enthusiasm may flare up intensely, then leave them exhausted when the initial fuel is spent. Their easygoing nature can make them overlook practical limits, promising more than they can sustain. When the blaze fades, they may feel empty or resentful, mistaking the dying embers for personal failure rather than a natural cycle. Learning to tend their fire slowly is their great growth edge.
The NaYin: Mountain-Fire (山头火 Shan-Tou-Huo)
In classical Chinese astrology, each of the 60 year-stem combinations carries a specific NaYin (纳音, “assigned tone”) — a poetic elemental melody refining the Five Elements into 30 archetypes. The Mountain-Fire (山头火) NaYin represents a unique expression of the fire element.
Classical Sources
《三命通会》(Comprehensive Treatise on the Three Fates)
By 万民英 (Wan Minying), Ming Dynasty, 1587 — Volume 30, “On NaYin Elements”:
“山头火者,以戌亥为天门,火照天门,其光至高,故曰山头火。野焚燎原之火,火光滔天,远远可见。”
“乙亥,伏明之火,需借木(如平地木、松柏木、大林木)生旺,方精气十足而兴发。”
Born in January or February?
There are two systems for determining your zodiac year. Folk tradition uses Lunar New Year (late Jan / early Feb). BaZi astrology uses Lichun (立春, Start of Spring, ~Feb 3–5). If your birthday falls in this boundary period, you might belong to the previous sign (Dog) under one system but the Mountain-Fire Pig under another. Use our BaZi Calculator to determine your exact pillar based on Lichun.
Personality
The Mountain-Fire Pig brings campfire energy to a world that often demands bonfires—visible, warm, but finite. Their gift is knowing when to light the spark and when to let it smolder, turning their natural charm into a renewable source of connection rather than a single brilliant flash. In modern life, they thrive by pacing their generosity.
Imagine a bonfire lit atop a mountain peak at dusk — the flames leap high, visible from every valley below, yet the wind that feeds them carries a hint of damp from the earth. This is the Mountain-Fire Pig (乙亥, 山头火 (Shan-Tou-Huo)): a soul whose warmth radiates outward with irresistible magnetism, but whose inner fire is fed by deep emotional reserves. The Pig’s native generosity and love of life are here set ablaze by the NaYin’s ‘Fire on a mountain peak,’ creating a personality that illuminates every room yet burns with a volatility that can surprise even those closest to them. The heavenly stem Yi (乙), soft wood, acts as kindling — it gives this Pig a supple, adaptive charm, but also a tendency to flare up when under pressure, especially since the earthly branch Hai (亥) is Water, the element that naturally quenches fire. The Sanming Tonghui (三命通会) notes that this pairing requires ‘wood to flourish’ — meaning the Mountain-Fire Pig needs supportive relationships and environments to sustain their light. Without them, the fire may smolder into impatience or emotional exhaustion. There is a paradox here: they are both the warmest companion and the most easily overwhelmed, a beacon of passion that can flicker into frustration if not tended with care.
Love & relationships
The Mountain-Fire Pig loves like a wildfire spreading across a hillside — sudden, all-consuming, and impossible to ignore. Their approach to romance is marked by an intensity that draws partners in, but this very blaze can scorch if not balanced with the Pig’s innate need for comfort and stability. In early courtship, they are generous to a fault, showering their beloved with attention and gifts, yet they expect the same fervent loyalty in return. Their love language is acts of devotion: they will cook elaborate meals, plan surprise getaways, and defend their partner fiercely. However, the wood stem Yi imparts a need for growth — they seek a relationship that evolves, like a tree sending roots deeper each year. The tiger, as their Liuhe (六合) match, offers the perfect counterbalance: the tiger’s bold independence fans the Pig’s fire without smothering it, while the Pig’s warmth softens the tiger’s edges. Their blind spot is impatience — when a relationship stalls or feels routine, the Mountain-Fire Pig may lash out or withdraw abruptly. To sustain love, they must learn to let the fire burn low and steady, rather than constantly chasing the peak.
Career & professional path
In the professional realm, the Mountain-Fire Pig is a natural beacon — their charisma and passion make them compelling leaders, especially in fields that require long-term vision and emotional resonance. The NaYin’s ‘fire on a peak’ imagery suits careers where they can be seen and inspire others: education, where they ignite curiosity; environmental work, where they champion causes with heartfelt zeal; or the arts, where their emotional depth translates into powerful creations. The wood stem Yi gives them a ‘growth’ trajectory — they thrive in roles that allow gradual expansion, like publishing, agriculture, or sustainable enterprise. They are not suited to quick-profit schemes or cutthroat competition; the fire needs steady fuel, not flash-in-the-pan bursts. Yet their career vulnerability lies in their own intensity: they can burn out if they take on too many projects or refuse to delegate. The Sanming Tonghui warns that the Mountain-Fire Pig must ‘borrow wood to flourish’ — meaning they need mentors, collaborators, or a supportive team to sustain their flame. Without this, they risk becoming a wildfire that exhausts its own resources.
Health & wellness
The Mountain-Fire Pig’s health is a careful equilibrium between blazing vitality and the risk of burnout. Fire governs the heart and small intestine in Chinese medicine, while the Pig’s earthly branch corresponds to the kidneys and water metabolism. This creates a tension: the fire element wants to rise and expand, but the water base must keep it grounded. If harmony is lost, this pairing may experience heart palpitations, insomnia, or emotional volatility — signs that the fire has flared beyond control. The wood stem Yi adds a third layer: wood rules the liver and gallbladder, making stress-induced stagnation a key concern. To harmonize these energies, the Mountain-Fire Pig needs practices that cool and nourish the water element: swimming, gentle yoga, or evening walks by water. Avoid excessive caffeine or stimulants that fan the fire. Crucially, they must honor their need for rest — the NaYin’s ‘mountain peak’ burns brightest when well rested, but crashes hard when depleted. A consistent sleep schedule (before 11 PM) and a diet rich in dark, leafy greens and root vegetables help anchor their spirit.
Wealth & finances
The Mountain-Fire Pig’s financial journey mirrors their NaYin: a blaze that illuminates widely but can consume resources quickly. They earn money through passion and generosity — often in professions that align with their values — but their spending is equally heartfelt, splurging on loved ones or causes they believe in. This pairing is not naturally frugal; they see money as a tool for spreading warmth, not hoarding. The wood stem Yi encourages ‘compound growth’ — they do best with long-term investments, real estate, or systematic savings plans that build slowly like tree rings. Their financial pitfall is impulsiveness: a sudden inspiration or emotional trigger can lead to lavish purchases or risky ventures. The ‘mountain fire’ image suggests that their wealth peaks in cycles — they may experience periods of abundance followed by lean times if they don’t manage reserves. A wise practice is to set aside a ‘firewall’ fund — a portion of income that is untouchable, ensuring that even if the blaze dims, the embers remain. Philanthropy suits them well, but only after securing their own foundation.
Growth & self-development
The Mountain-Fire Pig’s greatest growth edge lies in learning to temper their own flame. Like a bonfire that must be tended to burn all night, they must master Developing mastery in sustainable passion — knowing when to add fuel and when to let the embers glow. The NaYin teaches them that fire on a peak is magnificent but exposed; without a forest of support, it can be extinguished by the first storm. Their practice: each morning, ask ‘What is my one true priority today?’ and let the rest fall away. The wood stem Yi gives them the ability to grow, but also the tendency to branch in too many directions. By pruning distractions — saying no to secondary goals, limiting social obligations — they channel their fire into a focused, luminous beam. The classical text hints that this pairing ‘needs wood to flourish,’ which translates to building a circle of trusted mentors and friends who can reflect their light back to them. When the Mountain-Fire Pig learns to burn not as a wildfire but as a hearth fire — steady, warm, and enduring — they become an extraordinary force: a leader who inspires without consuming, a creator whose works outlast the night.

Since 山头火 represents a contained flame, activities like swimming, yoga, or tai chi help balance their inner heat.

They are wise to automate savings and consult a financial planner. Born in 1935 or 1995, they learn through experience that true security comes from steady saving, not just big gestures. Moderation is key.
How does the fire element challenge the Pig to evolve?
The fire element in 乙亥 (Mountain-Fire Pig) challenges the naturally easygoing Pig to become more assertive and passionate. 山头火 (Mountain Fire) symbolizes controlled, persistent flame—teaching the Pig to direct its energy purposefully rather than dissipating it in indulgence.

Why is 1935 called Mountain-Fire Pig instead of Wood Pig?

Both names refer to the same year: the Stem name (Wood Pig) describes its foundational energy, while the NaYin name (Mountain-Fire Pig) reveals its poetic-spiritual quality.
