⚡ Executive Bazi & Nayin Summary: The Ất Tỵ (乙巳 — Yi Si) Pillar
Deep qi lies hidden. Look beyond the surface zodiac. Within classical Ziping Four Pillars metaphysics and the ancient Nayin doctrine of San Ming Tong Hui, the Ất Tỵ (乙巳 — Yǐ Sì / Yi Si) pillar represents a profound structural convergence between Heavenly Stem Ất (Yin Wood) above and Earthly Branch Tỵ (Yin Fire) below, forging the distinctive Luminous Output Venting (Tinh Hoa Tiết Tú) formation across the Year, Month, Day, and Hour Palaces.
- Sexagenary Rank & Xun Void: Ranks #42/60 in the Sixty Jiazi cycle, belonging to the Giáp Thìn (Jia Chen) Xun (Emptiness / Void at Dần, Mão (Yin, Mao)), symbolized by the Snake (巳).
- Stem–Branch Axis & 12 Life Stage: Stem Generates Branch (Output Venting) — Ất seated on Tỵ occupies the Mộc Dục (Bath) stage (Romantic, aesthetically sensitive, and eager to absorb new experiences, though requiring discipline to avoid distraction or Peach Blossom entanglements.).
- Hidden Stems & Seated Ten Gods: Branch Tỵ conceals Bính (丙 — Main Qi 60%, Hurting Officer (Thương Quan)), Mậu (戊 — Middle Qi 30%, Direct Wealth (Chính Tài)), Canh (庚 — Residual Qi 10%, Direct Officer (Chính Quan)); the primary seated Ten God is Hurting Officer (Thương Quan) (傷官).
- Classical Nayin Destiny (San Ming Tong Hui): Lamp Fire (Phú Đăng Hỏa — 覆燈火) — Fire Element (Covered treasure-lamp flame illuminating chambers where sun and moon do not reach).
- Harmony & Clash Matrix: Heaven-and-Earth Twin Harmony with Canh Thân (Geng Shen); Stem-Clash Branch-Opposition with Tân Hợi (Xin Hai), Kỷ Hợi (Ji Hai); Same-Stem Clash with Ất Hợi (Yi Hai); Three-Harmony Trine Tỵ – Dậu – Sửu (Si–You–Chou Metal Bureau); Six Harmony Thân / Shen (Transforms to Water).
- Shen Sha & Nobleman Stars: Heavenly Nobleman at Tý, Thân (Zi, Shen); Academic Star at Ngọ (Wu); Thriving Lu at Mão (Mao); Sky Horse at Hợi (Hai); Peach Blossom at Ngọ (Wu); Elegant Canopy at Sửu (Chou); Formation: Ten-Great-Reversals Day (Thập Ác Đại Bại — Requires Strict Treasury Discipline), Solitary Phoenix Star (Cô Loan Sát — Requires Emotional Empathy in Marriage).
1 What Is Ất Tỵ (Yi Si)? Stem–Branch Anatomy & Ziping Qi Mechanics
Qi demands a root. Destiny follows its source. In classical sexagenary horology and Ziping Four Pillars Bazi, Ất Tỵ (乙巳 — Yǐ Sì / Yi Si) stands as Pillar #42/60 of the Sixty Jiazi cycle, forged by the vertical union of Heavenly Stem Ất (乙) representing manifest heavenly timing and Earthly Branch Tỵ (巳) representing the terrestrial foundation that anchors the entire chart from below.
Examine the upper canopy first. At the Heavenly Stem level, Ất embodies Yin Wood (Due East, thriving in Spring), evoking the classical image of Supple creeping vines, orchids and spring shoots, the graceful breeze winding across fertile meadows; the canonical treatise Di Tian Sui (滴天髓) captures its essence in the immortal verse “乙木雖柔，刲羊解牛，懷丁抱丙，跨鳳乘猴” (Yǐ mù suī róu, kuī yáng jiě niú, huái dīng bào bǐng, kuà fèng chéng hóu); Di Tian Sui (滴天髓) illuminates that although Yi Wood is as pliant as flowering vines, once deeply rooted it can cleave Wei Earth (Goat) and split Chou Earth (Ox); so long as it embraces Bing and Ding Fire for warmth within the chart, it can ride atop You (Phoenix/Rooster) or Shen (Monkey) amidst heavy Metal killing qi without fear.
The terrestrial root decides endurance. Never overlook the lower branch. At the Earthly Branch foundation, Tỵ belongs to Yin Fire, corresponds to the Snake zodiac, governs the solar month of 4th Lunar Month (Early Summer — Fire Thrives, Metal Born), aligns with South-Southeast (142.5°–157.5°), and rules the double-hour 09:00 – 11:00; what gives Branch Tỵ its profound multidimensionality in Bazi analysis is its internal reservoir of Hidden Stems (Ren Yuan Yong Shi) containing Bính (丙 — Main Qi 60%, Hurting Officer (Thương Quan)), Mậu (戊 — Middle Qi 30%, Direct Wealth (Chính Tài)), Canh (庚 — Residual Qi 10%, Direct Officer (Chính Quan)), while clearly distinguishing the Classical Nayin layer (Lamp Fire — Fire) from the Five-Element Stem–Branch axis (Ất Wood seated on Tỵ Fire).
2 Nayin Lamp Fire (Phú Đăng Hỏa) — Exegesis from San Ming Tong Hui & Lan Tai Miao Xuan
Nayin is acoustic resonance. Its metaphysical law is subtle. Unlike the raw Five Elements of individual stems and branches, Nayin Five Elements (納音五行) derive from the ancient harmonic pairing of the Sixty Jiazi with the Five Musical Tones and Twelve Pitch Pipes, wherein Ất Tỵ (乙巳) and its twin pillar Giáp Thìn (Jia Chen) share the Nayin identity of Lamp Fire (Phú Đăng Hỏa — 覆燈火, Covered treasure-lamp flame illuminating chambers where sun and moon do not reach) under the Fire Element.
Here lies the subtlest distinction. Never conflate the two twins. Although both carry the banner of Lamp Fire, because Ất Tỵ occupies the Mộc Dục (Bath) life stage within the Giáp Thìn (Jia Chen) Xun (Void at Dần, Mão (Yin, Mao)), it rejoices when encountering complementary Nayin pillars such as Giản Hạ Thủy (Ravine Water), Tuyền Trung Thủy (Spring Water — as lamp oil), Dương Liễu Mộc, Bích Thượng Thổ, Kim Bạch Kim to achieve noble stature, while requiring vigilance against incompatible Nayin forces like Đại Hải Thủy (Great Ocean Water), Thiên Hà Thủy (Sky River Water), Tích Lịch Hỏa (tempests extinguishing the lamp).
📜 Classical Exegesis from San Ming Tong Hui & Lan Tai Miao Xuan on Lamp Fire (覆燈火)
Canonical Record in San Ming Tong Hui (Ming Dynasty): The classical text states the principle with crystalline precision. Its metaphysical reasoning runs deep. San Ming Tong Hui (三命通會) writes: 'Fu Deng Huo (Lamp Fire) burns in a golden bowl atop a jade stand in Chen and Si, casting light into places untouched by sun or moon.'.
Canonical Poetic Imagery in Lan Tai Miao Xuan (Song Dynasty): The pairing of symbolic forms follows strict laws. Only true structural resonance yields high nobility. Lan Tai Miao Xuan (蘭臺妙選) expounds: 'The covered lamp requires Ravine Water or Spring Water as pure lamp oil, Great Forest Wood or Willow Wood as its wick, and Wall Earth or Roof-Tile Earth to shelter it from wind.'.
Differentiating Ất Tỵ from Giáp Thìn: Shared Nayin, divergent polarity. Yang and Yin paths unfold differently. Within the Ất Tỵ (Yin) pillar: Ất Tỵ (Yi Si) is 'Officialdom Fire' where Yi Wood feeds the vigorous flame of Si Fire below; radiant, eloquent, strategically incisive, and magnetic in public life. Conversely, within its twin pillar Giáp Thìn: Giáp Thìn (Jia Chen) is a Ten-Spirit (Thập Linh) pillar where Jia Wood forms a sturdy wick atop the Dragon stand of Chen Earth holding Gui Water oil; erudite, visionary, and gifted in enlightening leadership.
3 Ất Tỵ Birth Years, Lichun Solar Term Boundary & Eight Mansions Gua
Sixty years complete one great cycle. Astronomical law admits no ambiguity. Every 60 years the Ất Tỵ (乙巳) pillar returns, yet natives born in different 60-year epochs or of different genders carry distinct Eight Mansions (Ba Zhai) Ming Gua; above all, the transition of the Year Pillar in Bazi and Feng Shui is governed strictly by the astronomical Start of Spring (Lichun / Lập Xuân around February 3–5), NOT Lunar New Year's Day (Tết) (those born before Lichun of 1965 belong to the preceding Giáp Thìn year, whereas those born after Lichun of the following year belong to Bính Ngọ):
| Gregorian Solar Year | Sexagenary Year Pillar | Nayin Destiny | Zodiac Animal | Eight Mansions Ming Gua (Male / Female) |
|---|---|---|---|---|
| 1905 (After Lichun / Start of Spring) | Ất Tỵ (乙巳 — Yi Si) | Lamp Fire (Phú Đăng Hỏa — Fire) | Snake (巳) | Male: Kun (Earth — West Group) Female: Kan (Water — East Group) |
| 1965 (After Lichun / Start of Spring) | Ất Tỵ (乙巳 — Yi Si) | Lamp Fire (Phú Đăng Hỏa — Fire) | Snake (巳) | Male: Gen (Earth — West Group) Female: Dui (Metal — West Group) |
| 2025 (After Lichun / Start of Spring) | Ất Tỵ (乙巳 — Yi Si) | Lamp Fire (Phú Đăng Hỏa — Fire) | Snake (巳) | Male: Kan (Water — East Group) Female: Gen (Earth — West Group) |
4 Psychological Profile, Behavioral Architecture & Male/Female Temperament of Ất Tỵ
Character shapes destiny. Inner qi directs outer action. The psychological architecture of an individual carrying the Ất Tỵ (乙巳) pillar synthesizes the outward disposition of Heavenly Stem Ất (Supple creeping vines, orchids and spring shoots, the graceful breeze winding across fertile meadows), the subterranean drive of Earthly Branch Tỵ (concealing Hurting Officer (Thương Quan)) at the Mộc Dục (Bath) stage, and the symbolic resonance of Lamp Fire; Heavenly Stem Ất (Wood) channels its vitality downward into Earthly Branch Tỵ (Fire), creating an Eating God or Hurting Officer venting pattern of agile intellect, artistic expression, and strategic finesse.
Male & Female Expressions of Ất Tỵ: Men uphold honor and strategic resolve. Women embody resilient grace and discernment. A male chart anchored by Ất Tỵ blends the adaptable, tactful, aesthetically refined, resilient under pressure, and skilled at navigating complex human networks ethos of Ất with the pragmatic execution of seated Hurting Officer (Thương Quan) to build enduring enterprises; meanwhile, a female chart with Ất Tỵ radiates self-reliant intelligence infused with Hurting Officer (Thương Quan) (Inventive, incisive, expressive, breaking conventional molds with brilliance), though under the influence of Ten-Great-Reversals Day (Thập Ác Đại Bại — Requires Strict Treasury Discipline) she benefits from releasing perfectionism and nurturing open emotional dialogue.
Psychological Shadow to Transmute: Excessive rigidity invites fracture. Over-brooding drains vital spirit. The primary vulnerability of Ất seated on Tỵ is a tendency to become internally hesitant, sensitive to environmental shifts, and occasionally overly accommodating or averse to direct confrontation, particularly during transit years triggering Stem-Clash Branch-Opposition (Tân Hợi (Xin Hai), Kỷ Hợi (Ji Hai)) or activating the Xun Void branches (Dần, Mão (Yin, Mao)), when cognitive rigidity or emotional isolation must be consciously tempered.
5 The Ất Tỵ Pillar in a Bazi Chart: 4 Natal Palaces & 4-Season Climate Regulation
Bazi centers upon the Day Master. Four pillars govern four life realms. Taking Heavenly Stem Ất (Yin Wood) as the reference point, the internal hidden-stem matrix beneath Earthly Branch Tỵ and the functional role of Ất Tỵ across the Year, Month, Day, and Hour Palaces unfold as follows:
5.1. Hidden Stems, Seated Ten Gods & 12 Life Stage Matrix of Ất Tỵ
| Hidden Stem Layer / System | Heavenly Stem / Coordinate | Seated Ten God / State | Metaphysical Function & Real-World Manifestation |
|---|---|---|---|
| Main Qi (60%) | Bính (丙) — Yang Fire | Hurting Officer (Thương Quan) (傷官) | Inventive, incisive, expressive, breaking conventional molds with brilliance |
| Middle Qi (30%) | Mậu (戊) — Yang Earth | Direct Wealth (Chính Tài) (正財) | Prudent, reliable, stewarding assets and sustainable cashflow with discipline |
| Residual Qi (10%) | Canh (庚) — Yang Metal | Direct Officer (Chính Quan) (正官) | Principled, honorable, civic-minded, upholding institutional order and status |
| 12 Stages of Growth | Ất seated on Tỵ | Mộc Dục (Bath) Stage | Romantic, aesthetically sensitive, and eager to absorb new experiences, though requiring discipline to avoid distraction or Peach Blossom entanglements. |
| Xun Void (Không Vong) | Giáp Thìn (Jia Chen) Xun | Void: Dần, Mão (Yin, Mao) | Whichever natal palace houses Dần, Mão (Yin, Mao) experiences lightened material attachment or sublimes toward research, strategy, and spiritual philosophy. |
5.2. Diagnostic Differentiation of Ất Tỵ Across the 4 Palaces (Year – Month – Day – Hour)
🏛 1. Ất Tỵ in the Year Pillar (Ages 01 – 16)
Ancestral root of the chart. Foundation of early upbringing. Placed in the Year Pillar, Ất Tỵ establishes the native's Lamp Fire (Fire) Nayin destiny; Stem Ất reveals a family tradition that is adaptable, tactful, aesthetically refined, resilient under pressure, and skilled at navigating complex human networks, while Branch Tỵ concealing Hurting Officer (Thương Quan) indicates early self-reliance or leaving the ancestral hometown if clashed by the Month Branch (Hợi (Hai)).
🧭 2. Ất Tỵ in the Month Pillar (Ages 17 – 32)
The Month Decree commands authority. Six-tenths of destiny hinges here. Occupying the Month Pillar (solar season of 4th Lunar Month (Early Summer — Fire Thrives, Metal Born)), the Fire qi of Branch Tỵ and its hidden stems (Bính, Mậu, Canh) define the primary Structural Pattern, while Stem Ất projecting above empowers Wood executive leadership throughout young adulthood.
👑 3. Ất Tỵ in the Day Pillar (Ages 33 – 48)
Sovereign axis of the self. Inner chamber of marriage. As the Day Pillar, Ất Tỵ forms the Luminous Output Venting (Tinh Hoa Tiết Tú) configuration at the Mộc Dục (Bath) stage; the Spouse Palace Tỵ housing Hurting Officer (Thương Quan) (傷官) and Ten-Great-Reversals Day (Thập Ác Đại Bại — Requires Strict Treasury Discipline) portrays a spouse endowed with Inventive, incisive, expressive, breaking conventional molds with brilliance, ensuring resilient matrimony when Hợi (Hai) clashes are harmonized.
🌳 4. Ất Tỵ in the Hour Pillar (Age 49 Onward)
Harvest of the golden years. Sanctuary of children and legacy. Seated in the Hour Pillar (09:00 – 11:00), the Lamp Fire qi and Luminous Output Venting (Tinh Hoa Tiết Tú) structure crystallize in late life; when Ất Wood and Tỵ Fire serve as Favorable Useful Gods, the native enjoys affluent longevity and accomplished offspring.
5.3. Four-Season Climate Regulation Matrix (Tiao Hou Yong Shen) from Qiong Tong Bao Jian
Climate governs nobility. Seasonal balance takes precedence. According to Qiong Tong Bao Jian (窮通寶鑑), for the Ất Tỵ pillar to achieve upper-tier prosperity, the chart must first secure its Climate-Regulating Useful God (Điều Hậu Dụng Thần) to balance Cold, Heat, Dryness, and Dampness across the four birth seasons:
| Birth Season (Month Decree) | Qi State of Ất (Wood) | Climatic Imbalance | Climate-Regulating & Balancing Useful Gods (Qiong Tong Bao Jian) |
|---|---|---|---|
| Spring (Yin, Mao, Chen) | Spring Wood under Wood decree | Residual chill / exuberant Wood | In the spring months when tender shoots sprout, heavy Metal is strictly taboo lest it wound the nascent buds; Bing Fire is cherished as warm sunlight alongside Gui Water as gentle rain so flowers and foliage may unfurl in full radiance. |
| Summer (Si, Wu, Wei) | Summer Fire blazes, Earth parched | Scorching heat & drought | In the blazing summer months when fierce heat parches the meadows, Gui Water stands as the supreme Climate-Regulating God to relieve drought, assisted by moderate Bing Fire and Geng-Xin Metal to replenish the Water source. |
| Autumn (Shen, You, Xu) | Autumn Metal holds crisp authority | Dry atmosphere & sharp Metal | In the autumn months when crisp Metal qi sweeps the land and blossoms fade into ripened seed, Bing Fire is favored to temper the Metal chill while Gui Water nourishes the roots, or Jia Wood appears for the auspicious 'Vine Entwining the Tall Tree' (Teng Luo Xi Jia) formation. |
| Winter (Hai, Zi, Chou) | Winter Water freezes heaven & earth | Severe frost & glacial lock | In the bitter winter months when heaven freezes and earth locks, all botanical life retreats inward; Bing Fire—the solar orb—is the sole life-saving Useful God, ensuring that cold Wood turns toward the sun and achieves both fame and fortune. |
6 Career Trajectory, Executive Vocations & Wealth Architecture of Ất Tỵ
Wealth follows structural alignment. Prosperity requires timely cycles. Individuals carrying the Ất Tỵ (乙巳) pillar command a dual competitive advantage derived from their primary seated Ten God Hurting Officer (Thương Quan) (傷官) inside Branch Tỵ and the classical imagery of Lamp Fire (Covered treasure-lamp flame illuminating chambers where sun and moon do not reach), excelling in Fire industries (Artificial intelligence & electronics, renewable energy, media & entertainment, fine arts, gastronomy, leadership coaching & psychology) as well as Wood vocations (Education & academia, pharmaceuticals & herbal medicine, forestry & agribusiness, publishing & media, sustainable architecture, cultural arts).
Guard treasury discipline. Reject reckless speculation. Empowered by seated Hurting Officer (Thương Quan) (Inventive, incisive, expressive, breaking conventional molds with brilliance), Ất Tỵ natives possess keen long-horizon valuation instincts; however, because Lamp Fire is sensitive to Đại Hải Thủy (Great Ocean Water), Thiên Hà Thủy (Sky River Water), Tích Lịch Hỏa (tempests extinguishing the lamp), they should avoid high-leverage gambles during direct branch-clash years (Hợi (Hai)) or Stem-Clash Branch-Opposition (Tân Hợi (Xin Hai), Kỷ Hợi (Ji Hai)) transits.
7 Marriage, Compatibility, Shen Sha Stars & Harmony–Clash–Punishment Map
Human affinity follows energetic law. Synastry demands whole-chart synthesis. When evaluating marital compatibility or strategic partnerships for Ất Tỵ (乙巳), authentic Ziping Bazi examines Heavenly Stems, Earthly Branches, Nayin resonance, and Shen Sha auxiliary stars simultaneously:
| Interaction Tier / Shen Sha | Stem–Branch / Palace Coordinate | Auspiciousness & Practical Synastry Application |
|---|---|---|
| Heaven & Earth Twin Harmony | Pillar Canh Thân (Geng Shen) | Stem Ất unites with Canh / Geng (Transforms to Metal), Branch Tỵ unites with Thân / Shen (Transforms to Water); supreme marital and executive synergy that dissolves obstacles. |
| Three Harmonies, Six Harmonies & Directional | Trine: Tỵ – Dậu – Sửu (Si–You–Chou Metal Bureau) Six Harmony: Thân / Shen (Transforms to Water) • Directional: Tỵ – Ngọ – Mùi (Si–Wu–Wei Southern Fire) | Consolidates elemental momentum into a unified alliance, stabilizing the Spouse Palace and long-term partnerships. |
| Stem-Clash Branch-Opposition | Dual Clashes: Tân Hợi (Xin Hai), Kỷ Hợi (Ji Hai) Same-Stem Clash: Ất Hợi (Yi Hai) | Heavenly Stem clashes/competes while Earthly Branch opposes (Tỵ vs. Hợi (Hai)); requires a bridging Useful God and proactive patience. |
| Clash – Punishment – Harm – Break | Clash: Hợi (Hai) • Harm: Dần (Yin) Punishment: Dần, Thân / Yin, Shen (Ungrateful Punishment) • Break: Thân (Shen) | Can trigger friction, unspoken misunderstandings, or relational fatigue unless buffered by conscious empathy and Six-Harmony remedies. |
| Nobleman, Lu, Horse & Peach Blossom | Nobleman: Tý, Thân (Zi, Shen) • Academic: Ngọ (Wu) Lu: Mão (Mao) • Horse: Hợi (Hai) • Blossom: Ngọ (Wu) | Heavenly Nobleman turns crisis into grace; Academic Star elevates scholarship; Lu & Sky Horse fuel global wealth; Canopy (Sửu (Chou)) & Ten-Great-Reversals Day (Thập Ác Đại Bại — Requires Strict Treasury Discipline) shape charisma. |
8 Feng Shui Colors, Directions, Numbers & Dual-Layer Useful God Strategy
Remedies must address the root. Reject superficial formulas. In classical Feng Shui and Bazi luck enhancement for Ất Tỵ (乙巳), rigorous practitioners distinguish Layer 1: Annual Nayin Destiny (Lamp Fire — Fire Element) for daily social resonance from Layer 2: Natal Day Master Useful God (Ất Wood) for high-stakes career, investment, and spatial decisions:
| Enhancement Dimension | Layer 1: By Nayin Destiny Lamp Fire (Fire Element) | Layer 2: By Day Master Ất (Wood) Useful God |
|---|---|---|
| Auspicious Colors | • Same Element (Fire): Cinnabar red, peach blossom pink, warm amber-orange, radiant violet (Pure Fire) • Generating Mother: Lush emerald green, jade green, spring leaf green (Wood generates Fire) | • Weak Chart (needs Resource Water, Peer Wood): Water & Wood palettes • Strong Chart (needs Output Fire, Wealth Earth): Fire & Earth palettes |
| Colors to Moderate | Pitch black, deep abyssal navy (Water controls Fire) | Avoid overusing colors belonging to the chart's Unfavorable Element (Ji Shen) that disrupt seasonal climate balance. |
| Directions & Artifacts | • Sectors: Due South (Li — Native Fire Palace) / Due East (Zhen) and Southeast (Xun — Wood fuels Fire) • Numbers: Number 9 (Later Heaven) and 2, 7 (He Tu Fire) • Items: Natural amethyst, ruby, red carnelian, rose quartz, Himalayan salt lamp, aromatic agarwood incense | Prioritize the compass sector of your Natal Useful God, Heavenly Nobleman (Tý, Thân (Zi, Shen)), and Thriving Lu / Sky Horse (Mão (Mao), Hợi (Hai)). |
9 Strategic Destiny Cultivation & 3 Forensic Bazi Case Studies by Master Ung Khiem
To know destiny is to master destiny. Aligning with cosmic timing ensures triumph. The classical sages taught that “The noble person understands destiny and remains free from anxiety” — a native carrying the Ất Tỵ (乙巳) pillar who grasps the interplay between Lamp Fire and the Luminous Output Venting (Tinh Hoa Tiết Tú) axis can proactively ally with Giản Hạ Thủy (Ravine Water), Tuyền Trung Thủy (Spring Water — as lamp oil), Dương Liễu Mộc, Bích Thượng Thổ, Kim Bạch Kim partners, cultivate seated Hurting Officer (Thương Quan) virtues, and activate Sky Horse (Hợi (Hai)) and Nobleman (Tý, Thân (Zi, Shen)) mobility to neutralize Stem-Clash Branch-Opposition (Tân Hợi (Xin Hai), Kỷ Hợi (Ji Hai)) years.
9.1. Three Forensic Bazi Chart Case Studies Featuring Ất Tỵ (From Master Ung Khiem's Research Archives)
📂 Case Study #1: Ất Tỵ in the Year Pillar — Lamp Fire Achieving Noble Resonance
Forensic Diagnosis & Timing: Deep foundation. Limpid structural flow. Born in the Ất Tỵ (1965) year, this chart's Year Pillar Lamp Fire forms an auspicious Heaven-and-Earth Twin Harmony with the Month Pillar Canh Thân (Geng Shen), while the Hour Pillar anchors the Thriving Lu and regulates climate; entering Favorable Useful God Decade Luck (Fire – Earth) after age 32, the native built a premier enterprise in artificial intelligence & electronics.
📂 Case Study #2: Ất Tỵ Day Pillar Born in Mid-Winter — Supreme Climate Rescue via Bing Fire
Forensic Diagnosis & Timing: Extreme cold births returning warmth. A single Bing Fire redeems the entire chart. With the Ất Tỵ Day Pillar (Mộc Dục (Bath) stage, seated on Hurting Officer (Thương Quan)) born in the glacial Gui Chou winter month, the Hour Pillar Bing Wu (丙午) emerges like the meridian sun to thaw the frozen natal field in exact accordance with Qiong Tong Bao Jian, propelling the native from early-life hardship to executive leadership during the Ding Si – Wu Wu Decade Luck after age 35.
📂 Case Study #3: Ất Tỵ Encountering a Tân Hợi Stem-Clash Branch-Opposition Transit & Classical Resolution
Forensic Diagnosis & Remedy: Meet fierce clash with tactical yielding. Use affinity to dissolve opposition. When the annual transit pillar Tân Hợi (Xin Hai) struck the natal Month Pillar Ất Tỵ in a direct Stem-Clash Branch-Opposition (Fan Yin), the native proactively applied the classical protocol of “Resolving Clash via Six Harmony & Sky Horse Mobility”—restructuring operations, relocating the executive office toward the Nobleman sector (Zi, Shen), and partnering with a Shen (Water) ally to preserve capital and capture a new regional market.
10 Classical Canon & Scholarly Bibliography
Scholarship demands canonical roots. Every doctrine rests on primary texts. This monograph on the Ất Tỵ (乙巳 — Yi Si) pillar and its Lamp Fire (Phú Đăng Hỏa) Nayin destiny was compiled by Master Ung Khiem directly from the foundational classics of Ziping Bazi and Nayin metaphysics:
- San Ming Tong Hui (三命通會 — Wan Min-ying, Ming Dynasty): Volumes 1–3 Treatise on the Sixty Jiazi Nayin, examining the origin of Lamp Fire (覆燈火) and the structural divergence between Ất Tỵ and Giáp Thìn.
- Lan Tai Miao Xuan (蘭臺妙選 — Song Dynasty): Poetic imagery and Nayin resonance conditions for Lamp Fire.
- Di Tian Sui Chan Wei (滴天髓闡微 — Liu Bo-wen & Ren Tie-qiao): Canonical verses on Heavenly Stem Ất (“乙木雖柔，刲羊解牛，懷丁抱丙，跨鳳乘猴”) and Earthly Branch Tỵ.
- Qiong Tong Bao Jian (窮通寶鑑 — Yu Chun-tai): Twelve-month Climate-Regulating Useful God (Tiao Hou Yong Shen) selection for Stem Ất.
- Zi Ping Zhen Quan (子平真詮) & Yuan Hai Zi Ping (淵海子平): Doctrines of the Twelve Stages of Growth (Mộc Dục (Bath)), Hidden Stems & Seated Ten Gods (Hurting Officer (Thương Quan)), and Xun Void (Dần, Mão (Yin, Mao)).
Core Methodological Principle: One pillar never defines an entire life. All eight characters must be weighed together. Any analysis of the birth-year Nayin (Lamp Fire) or the standalone Ất Tỵ pillar represents only one-quarter of the natal blueprint; accurate destiny forecasting requires plotting the complete Four Pillars Bazi Chart (Year – Month – Day – Hour) alongside 10-Year Decade Luck and Annual Transits.
Compiled from primary classical treatises—including San Ming Tong Hui, Di Tian Sui, Qiong Tong Bao Jian, and Zi Ping Zhen Quan—combined with empirical chart verification across thousands of consultations, this Sixty Jiazi series empowers readers to understand both their birth-year Nayin and the structural dynamics of their Four Pillars Bazi chart.
Plot your Four Pillars Bazi chart with Master Ung Khiem →11 Frequently Asked Questions About Ất Tỵ (乙巳 — Yi Si)
Rank #42 of 60. Belongs to the Giáp Thìn (Jia Chen) Xun. In classical Chinese and Vietnamese sexagenary horology, Ất Tỵ (乙巳 — Yǐ Sì) unites Heavenly Stem Ất (Yin Wood) with Earthly Branch Tỵ (Yin Fire, Zodiac Snake), placing its Xun Void at Dần, Mão (Yin, Mao) and carrying the Nayin destiny of Lamp Fire (Phú Đăng Hỏa — Covered treasure-lamp flame illuminating chambers where sun and moon do not reach).
Fire Element destiny. Nayin Lamp Fire (Phú Đăng Hỏa). Individuals born in the Ất Tỵ year correspond to Gregorian solar years 1905, 1965, 2025 (measured strictly from the Start of Spring / Lichun solar term); according to the Ming-dynasty compendium San Ming Tong Hui, they embody 覆燈火 (Covered treasure-lamp flame illuminating chambers where sun and moon do not reach) with unmistakable inner resilience.
Seated on Hurting Officer (Thương Quan). Occupies the Mộc Dục (Bath) stage. Beneath Earthly Branch Tỵ of the Ất Tỵ pillar lie the hidden stems Bính (Main Qi — Hurting Officer (Thương Quan)), Mậu (Middle Qi — Direct Wealth (Chính Tài)), Canh (Residual Qi — Direct Officer (Chính Quan)); when referenced against Heavenly Stem Ất, the primary seated qi is Hurting Officer (Thương Quan) (傷官), establishing a Luminous Output Venting (Tinh Hoa Tiết Tú) structural dynamic.
Distinct character. Deep marital loyalty. When Ất Tỵ occupies the Day Pillar, Day Master Ất (Wood) sits directly upon the Spouse Palace Tỵ (Fire) housing Hurting Officer (Thương Quan), making the native adaptable, tactful, aesthetically refined, resilient under pressure, and skilled at navigating complex human networks while requiring conscious mindfulness to temper tendencies of being internally hesitant, sensitive to environmental shifts, and occasionally overly accommodating or averse to direct confrontation so domestic harmony endures.
Thrives with Canh Thân. Clashes with Tân Hợi. The Ất Tỵ pillar achieves supreme synergy when meeting its Twin Harmony partner Canh Thân (Geng Shen) (Heaven-and-Earth Union), the Three-Harmony trine (Tỵ – Dậu – Sửu (Si–You–Chou Metal Bureau)), and Six-Harmony partner (Thân / Shen (Transforms to Water)); conversely, caution is required during Tân Hợi (Xin Hai) or Kỷ Hợi (Ji Hai) (Stem-Clash Branch-Opposition) and direct Hợi (Hai) clashes.
Palace shifts meaning. Timing alters destiny. In the Year Pillar it governs ancestral heritage and Lamp Fire innate qi; in the Month Pillar it sets the career structure around Hurting Officer (Thương Quan); in the Day Pillar it defines core psychology and spouse dynamics; in the Hour Pillar it shapes late-life wealth and children after age 49.
Climate comes first. Strength follows second. According to Qiong Tong Bao Jian (Exhaustive Treasury of Seasonal Harmonization), Stem Ất (Wood) of the Ất Tỵ pillar born in Spring requires warming residual chill, Summer demands Water to relieve scorching heat, Autumn needs balanced Metal-Fire tempering, and Winter urgently requires Bing Fire to thaw the frozen chart.
Favors Fire phase. Nobleman at Zi, Shen. By Nayin destiny Lamp Fire, Ất Tỵ natives harmonize with Cinnabar red, peach blossom pink, warm amber-orange, radiant violet (Pure Fire), directions Due South (Li — Native Fire Palace), and enjoy Heavenly Nobleman protection at Tý, Thân (Zi, Shen), Academic Star at Ngọ (Wu), Thriving Lu at Mão (Mao), and Sky Horse mobility at Hợi (Hai).
