⚡ Executive Bazi & Nayin Summary: The Geng Zi (庚子 · Geng Zi) 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 Geng Zi (庚子 · Gēng Zǐ / Geng Zi) pillar represents a profound structural convergence between Heavenly Stem Geng (Yang Metal) above and Earthly Branch Zi (Yang Water) below, forging the distinctive Luminous Output Venting (Refined Output Brilliance (Jing Hua Xie Xiu)) formation across the Year, Month, Day, and Hour Palaces.

1 What Is Geng Zi? Stem-Branch Anatomy & Ziping Qi Mechanics
Qi demands a root. Destiny follows its source. In classical sexagenary horology and Ziping Four Pillars Bazi, Geng Zi (庚子 · Gēng Zǐ / Geng Zi) stands as Pillar #37/60 of the Sixty Jiazi cycle, forged by the vertical union of Heavenly Stem Geng (庚) representing manifest heavenly timing and Earthly Branch Zi (子) representing the terrestrial foundation that anchors the entire chart from below.
Examine the upper canopy first. At the Heavenly Stem level, Geng embodies Yang Metal (Due West, thriving in Autumn), evoking the classical image of Unrefined mountain ore, battle-axes and broadswords, the commanding martial frost of autumn; the canonical treatise Di Tian Sui (滴天髓) captures its essence in the immortal verse “庚金帶煞，剛健為最，得水而清，得火而銳” (Gēng jīn dài shà, gāng jiàn wéi zuì, dé shuǐ ér qīng, dé huǒ ér ruì); Di Tian Sui (滴天髓) declares that Geng Metal carries the martial killing authority of autumn and is the most resolute of all Ten Stems; when washed by Ren Water its talent becomes crystalline and pure, and when smelted by Ding Fire it is forged into a razor-sharp imperial blade.
The terrestrial root decides endurance. Never overlook the lower branch. At the Earthly Branch foundation, Zi belongs to Yang Water, corresponds to the Rat zodiac, governs the solar month of 11th Lunar Month (Mid-Winter · Peak Water), aligns with Due North (352.5°-7.5°), and rules the double-hour 23:00 to 01:00; what gives Branch Zi its profound multidimensionality in Bazi analysis is its internal reservoir of Hidden Stems (Ren Yuan Yong Shi) containing Gui (癸, Main Qi 100%, Hurting Officer (Hurting Officer (Shang Guan))), while clearly distinguishing the Classical Nayin layer (Wall Earth · Earth) from the Five-Element Stem-Branch axis (Geng Metal seated on Zi Water).
2 Nayin Wall Earth (Wall Earth (Bi Shang Tu)) · 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 Geng Zi (庚子) and its twin pillar Xin Chou share the Nayin identity of Wall Earth (Wall Earth (Bi Shang Tu), 壁上土, Refined plaster and architectural masonry shielding halls and chambers from winter wind) under the Earth Element.
Here lies the subtlest distinction. Never conflate the two twins. Although both carry the banner of Wall Earth, because Geng Zi occupies the Tử (Stillness) life stage within the Jia Wu Xun (Void at Chen, Si (Chen, Si)), it rejoices when encountering complementary Nayin pillars such as Meadow Wood (Ping Di Mu) (Plains Wood), Pine and Cypress Wood (Song Bai Mu) (Pine & Cypress Wood), Roof-Tile Earth (Wu Shang Tu) (Roof-Tile Earth), Lamp Fire (Fu Deng Huo), Gold Foil Metal (Jin Bo Jin) to achieve noble stature, while requiring vigilance against incompatible Nayin forces like Great Ocean Water (Da Hai Shui) (Great Ocean Water), Long-Flowing Water (Chang Liu Shui) (Long-Flowing Water, eroding masonry walls).
📜 Classical Exegesis from San Ming Tong Hui & Lan Tai Miao Xuan on Wall Earth (壁上土)
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) states: 'Bi Shang Tu (Wall Earth) forms the walls of human palaces and dwellings in Zi and Chou, regulating cold and heat within while warding off frost and gale without.'.
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) explains: 'Wall Earth strictly requires Plains Wood (Ping Di Mu) or Pine & Cypress Wood as structural columns, Roof-Tile Earth as its canopy above, and Lamp Fire or Foothill Fire to warm the chamber.'.
Differentiating Geng Zi from Xin Chou: Shared Nayin, divergent polarity. Yang and Yin paths unfold differently. Within the Geng Zi (Yang) pillar: Geng Zi sits atop Zi Water (Geng Metal generating Gui Water Hurting Officer); razor-sharp in intellect and rapid in execution, though requiring Earth and Fire support so the wall remains warm and grounded. Conversely, within its twin pillar Xin Chou: Xin Chou is 'Self-Nourished Earth' kneaded from Ji Earth and Xin Metal inside Chou; fine-grained, resilient, and exceptionally skilled at preserving institutional and family wealth.
3 Geng Zi Birth Years, Lichun Solar Term Boundary & Eight Mansions Gua
Sixty years complete one great cycle. Astronomical law admits no ambiguity. Every 60 years the Geng Zi (庚子) 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 / Start of Spring (Lichun) around February 3 to 5), NOT Lunar New Year's Day (Tết) (those born before Lichun of 1960 belong to the preceding Ji Hai year, whereas those born after Lichun of the following year belong to Xin Chou):
| Gregorian Solar Year | Sexagenary Year Pillar | Nayin Destiny | Zodiac Animal | Eight Mansions Ming Gua (Male / Female) |
|---|---|---|---|---|
| 1900 (After Lichun / Start of Spring) | Geng Zi (庚子 · Geng Zi) | Wall Earth (Wall Earth (Bi Shang Tu) · Earth) | Rat (子) | Male: Kan (Water · East Group) Female: Gen (Earth · West Group) |
| 1960 (After Lichun / Start of Spring) | Geng Zi (庚子 · Geng Zi) | Wall Earth (Wall Earth (Bi Shang Tu) · Earth) | Rat (子) | Male: Xun (Wood · East Group) Female: Kun (Earth · West Group) |
| 2020 (After Lichun / Start of Spring) | Geng Zi (庚子 · Geng Zi) | Wall Earth (Wall Earth (Bi Shang Tu) · Earth) | Rat (子) | Male: Qian (Metal · West Group) Female: Li (Fire · East Group) |
4 Psychological Profile, Behavioral Architecture & Male/Female Temperament of Geng Zi
Character shapes destiny. Inner qi directs outer action. The psychological architecture of an individual carrying the Geng Zi (庚子) pillar synthesizes the outward disposition of Heavenly Stem Geng (Unrefined mountain ore, battle-axes and broadswords, the commanding martial frost of autumn), the subterranean drive of Earthly Branch Zi (concealing Hurting Officer (Hurting Officer (Shang Guan))) at the Tử (Stillness) stage, and the symbolic resonance of Wall Earth; Heavenly Stem Geng (Metal) channels its vitality downward into Earthly Branch Zi (Water), creating an Eating God or Hurting Officer venting pattern of agile intellect, artistic expression, and strategic finesse.
Male & Female Expressions of Geng Zi: Men uphold honor and strategic resolve. Women embody resilient grace and discernment. A male chart anchored by Geng Zi blends the decisive, chivalrous, forthright, unyielding in justice, and forged into greater brilliance through adversity ethos of Geng with the pragmatic execution of seated Hurting Officer (Hurting Officer (Shang Guan)) to build enduring enterprises; meanwhile, a female chart with Geng Zi radiates self-reliant intelligence infused with Hurting Officer (Hurting Officer (Shang Guan)) (Inventive, incisive, expressive, breaking conventional molds with brilliance), though under the influence of Balanced Orthodox Qi Formation (Neutral Dignity (Ping He) Chính Prana Cách · Steady & Centered) 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 Geng seated on Zi is a tendency to become overly blunt, uncompromising in speech, and prone to domineering competitiveness when unchecked, particularly during transit years triggering Stem-Clash Branch-Opposition (Bing Wu, Jia Wu) or activating the Xun Void branches (Chen, Si (Chen, Si)), when cognitive rigidity or emotional isolation must be consciously tempered.
5 The Geng Zi 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 Geng (Yang Metal) as the reference point, the internal hidden-stem matrix beneath Earthly Branch Zi and the functional role of Geng Zi across the Year, Month, Day, and Hour Palaces unfold as follows:
5.1. Hidden Stems, Seated Ten Gods & 12 Life Stage Matrix of Geng Zi
| Hidden Stem Layer / System | Heavenly Stem / Coordinate | Seated Ten God / State | Metaphysical Function & Real-World Manifestation |
|---|---|---|---|
| Main Qi (100%) | Gui (癸) · Yin Water | Hurting Officer (Hurting Officer (Shang Guan)) (傷官) | Inventive, incisive, expressive, breaking conventional molds with brilliance |
| 12 Stages of Growth | Geng seated on Zi | Tử (Stillness) Stage | Quiet inward concentration and philosophical depth; dedicating oneself to a specialized craft or scholarly discipline yields master-level authority. |
| Xun Void (Void (Kong Wang)) | Jia Wu Xun | Void: Chen, Si (Chen, Si) | Whichever natal palace houses Chen, Si (Chen, Si) experiences lightened material attachment or sublimes toward research, strategy, and spiritual philosophy. |
5.2. Diagnostic Differentiation of Geng Zi Across the 4 Palaces (Year, Month, Day, Hour)
🏛 1. Geng Zi in the Year Pillar (Ages 01 to 16)
Ancestral root of the chart. Foundation of early upbringing. Placed in the Year Pillar, Geng Zi establishes the native's Wall Earth Nayin destiny; Stem Geng reveals a family tradition that is decisive, chivalrous, forthright, unyielding in justice, and forged into greater brilliance through adversity, while Branch Zi concealing Hurting Officer (Hurting Officer (Shang Guan)) indicates early self-reliance or leaving the ancestral hometown if clashed by the Month Branch (Wu).
🧭 2. Geng Zi in the Month Pillar (Ages 17 to 32)
The Month Decree commands authority. Six-tenths of destiny hinges here. Occupying the Month Pillar (solar season of 11th Lunar Month (Mid-Winter · Peak Water)), the Water qi of Branch Zi and its hidden stems (Gui) define the primary Structural Pattern, while Stem Geng projecting above empowers Metal executive leadership throughout young adulthood.
👑 3. Geng Zi in the Day Pillar (Ages 33 to 48)
Sovereign axis of the self. Inner chamber of marriage. As the Day Pillar, Geng Zi forms the Luminous Output Venting (Refined Output Brilliance (Jing Hua Xie Xiu)) configuration at the Tử (Stillness) stage; the Spouse Palace Zi housing Hurting Officer (Hurting Officer (Shang Guan)) (傷官) and Balanced Orthodox Qi Formation (Neutral Dignity (Ping He) Chính Prana Cách · Steady & Centered) portrays a spouse endowed with Inventive, incisive, expressive, breaking conventional molds with brilliance, ensuring resilient matrimony when Wu clashes are harmonized.
🌳 4. Geng Zi in the Hour Pillar (Age 49 Onward)
Harvest of the golden years. Sanctuary of children and legacy. Seated in the Hour Pillar (23:00 to 01:00), the Wall Earth qi and Luminous Output Venting (Refined Output Brilliance (Jing Hua Xie Xiu)) structure crystallize in late life; when Geng Metal and Zi Water 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 Geng Zi pillar to achieve upper-tier prosperity, the chart must first secure its Climate-Regulating Useful God (Climatic Balancing Useful God (Tiao Hou Yong Shen)) to balance Cold, Heat, Dryness, and Dampness across the four birth seasons:
| Birth Season (Month Decree) | Qi State of Geng (Metal) | Climatic Imbalance | Climate-Regulating & Balancing Useful Gods (Qiong Tong Bao Jian) |
|---|---|---|---|
| Spring (Yin, Mao, Chen) | Spring Metal under Wood decree | Residual chill / exuberant Wood | In the spring months when Wood flourishes and Metal is imprisoned (Tù), raw Geng Metal is still nascent before the dense forest; it needs Wu Earth for protective nourishment, Bing-Ding Fire for smelting, and Jia Wood to feed the forge. |
| Summer (Si, Wu, Wei) | Summer Fire blazes, Earth parched | Scorching heat & drought | In the summer months when fierce Fire melts Metal and Geng sits in exhaustion, Ren Water is urgently needed to quench the furnace and control Fire, backed by moist Chen and Chou Earth to absorb heat and生 (generate) Metal. |
| Autumn (Shen, You, Xu) | Autumn Metal holds crisp authority | Dry atmosphere & sharp Metal | In the autumn months when Geng Metal holds sovereign seasonal command, raw iron demands the furnace of Ding Fire to forge it into a legendary sword, with Jia Wood serving as fuel to draw forth Ding Fire ('Fire Smelting Autumn Metal'). |
| Winter (Hai, Zi, Chou) | Winter Water freezes heaven & earth | Severe frost & glacial lock | In the winter months when freezing Water chills Metal ('Metal-Water Coldness'), the blade sinks beneath icy depths; Ding Fire must smelt the Metal while Bing Fire warms the entire chart for fame to manifest. |
6 Career Trajectory, Executive Vocations & Wealth Architecture of Geng Zi
Wealth follows structural alignment. Prosperity requires timely cycles. Individuals carrying the Geng Zi (庚子) pillar command a dual competitive advantage derived from their primary seated Ten God Hurting Officer (Hurting Officer (Shang Guan)) (傷官) inside Branch Zi and the classical imagery of Wall Earth (Refined plaster and architectural masonry shielding halls and chambers from winter wind), excelling in Earth industries (Real estate development, civil infrastructure, mining & resources, fund management, insurance, agriculture, executive governance consulting) as well as Metal vocations (Banking & finance, precision engineering, semiconductors, bullion & capital markets, legal compliance, auditing, luxury jewelry).
Guard treasury discipline. Reject reckless speculation. Empowered by seated Hurting Officer (Hurting Officer (Shang Guan)) (Inventive, incisive, expressive, breaking conventional molds with brilliance), Geng Zi natives possess keen long-horizon valuation instincts; however, because Wall Earth is sensitive to Great Ocean Water (Da Hai Shui) (Great Ocean Water), Long-Flowing Water (Chang Liu Shui) (Long-Flowing Water, eroding masonry walls), they should avoid high-leverage gambles during direct branch-clash years (Wu) or Stem-Clash Branch-Opposition (Bing Wu, Jia Wu) 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 Geng Zi (庚子), 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 Yi Chou | Stem Geng unites with Yi / Yi (Transforms to Metal), Branch Zi unites with Chou / Chou (Transforms to Earth); supreme marital and executive synergy that dissolves obstacles. |
| Three Harmonies, Six Harmonies & Directional | Trine: Shen · Zi · Chen (Shen-Zi-Chen Water Bureau) Six Harmony: Chou / Chou (Transforms to Earth) • Directional: Hai · Zi · Chou (Hai-Zi-Chou Northern Water) | Consolidates elemental momentum into a unified alliance, stabilizing the Spouse Palace and long-term partnerships. |
| Stem-Clash Branch-Opposition | Dual Clashes: Bing Wu, Jia Wu Same-Stem Clash: Geng Wu | Heavenly Stem clashes/competes while Earthly Branch opposes (Zi vs. Wu); requires a bridging Useful God and proactive patience. |
| Clash · Punishment · Harm · Break | Clash: Wu • Harm: Wei Punishment: Mao / Mao (Uncivilized Punishment) • Break: You | Can trigger friction, unspoken misunderstandings, or relational fatigue unless buffered by conscious empathy and Six-Harmony remedies. |
| Nobleman, Lu, Horse & Peach Blossom | Nobleman: Chou, Wei (Chou, Wei) • Academic: Hai Lu: Shen • Horse: Yin • Blossom: You | Heavenly Nobleman turns crisis into grace; Academic Star elevates scholarship; Lu & Sky Horse fuel global wealth; Canopy (Chen) & Balanced Orthodox Qi Formation (Neutral Dignity (Ping He) Chính Prana Cách · Steady & Centered) 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 Geng Zi (庚子), rigorous practitioners distinguish Layer 1: Annual Nayin Destiny (Wall Earth · Earth Element) for daily social resonance from Layer 2: Natal Day Master Useful God (Geng Metal) for high-stakes career, investment, and spatial decisions:
| Enhancement Dimension | Layer 1: By Nayin Destiny Wall Earth (Earth Element) | Layer 2: By Day Master Geng (Metal) Useful God |
|---|---|---|
| Auspicious Colors | • Same Element (Earth): Imperial yellow, rich umber brown, ochre gold, terracotta, espresso brown (Pure Earth) • Generating Mother: Warm crimson, rose pink, purple, brick orange (Fire generates Earth) | • Weak Chart (needs Resource Earth, Peer Metal): Earth & Metal palettes • Strong Chart (needs Output Water, Wealth Wood): Water & Wood palettes |
| Colors to Moderate | Dark forest green, intense emerald (Wood controls Earth) | Avoid overusing colors belonging to the chart's Unfavorable Element (Ji Shen) that disrupt seasonal climate balance. |
| Directions & Artifacts | • Sectors: Northeast (Gen) and Southwest (Kun, Native Earth Palaces) / Due South (Li, Fire nourishes Earth) • Numbers: Numbers 2, 5, 8 (Later Heaven) and 5, 10 (He Tu Earth) • Items: Natural citrine, golden-brown tiger-eye, yellow jade, fine porcelain ceramics, carved stone Desk Seal | Prioritize the compass sector of your Natal Useful God, Heavenly Nobleman (Chou, Wei (Chou, Wei)), and Thriving Lu / Sky Horse (Shen, Yin). |
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 Geng Zi (庚子) pillar who grasps the interplay between Wall Earth and the Luminous Output Venting (Refined Output Brilliance (Jing Hua Xie Xiu)) axis can proactively ally with Meadow Wood (Ping Di Mu) (Plains Wood), Pine and Cypress Wood (Song Bai Mu) (Pine & Cypress Wood), Roof-Tile Earth (Wu Shang Tu) (Roof-Tile Earth), Lamp Fire (Fu Deng Huo), Gold Foil Metal (Jin Bo Jin) partners, cultivate seated Hurting Officer (Hurting Officer (Shang Guan)) virtues, and activate Sky Horse (Yin) and Nobleman (Chou, Wei (Chou, Wei)) mobility to neutralize Stem-Clash Branch-Opposition (Bing Wu, Jia Wu) years.
9.1. Three Forensic Bazi Chart Case Studies Featuring Geng Zi (From Master Ung Khiem's Research Archives)
📂 Case Study #1: Geng Zi in the Year Pillar · Wall Earth Achieving Noble Resonance
Forensic Diagnosis & Timing: Deep foundation. Limpid structural flow. Born in the Geng Zi (1960) year, this chart's Year Pillar Wall Earth forms an auspicious Heaven-and-Earth Twin Harmony with the Month Pillar Yi Chou, while the Hour Pillar anchors the Thriving Lu and regulates climate; entering Favorable Useful God Decade Luck (Water, Wood) after age 32, the native built a premier enterprise in real estate development.
📂 Case Study #2: Geng Zi 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 Geng Zi Day Pillar (Tử (Stillness) stage, seated on Hurting Officer (Hurting Officer (Shang Guan))) 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: Geng Zi Encountering a Bing Wu 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 Bing Wu struck the natal Month Pillar Geng Zi 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 (Chou, Wei), and partnering with a Chou (Earth) 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 Geng Zi (庚子 · Geng Zi) pillar and its Wall Earth (Wall Earth (Bi Shang Tu)) 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 to 3 Treatise on the Sixty Jiazi Nayin, examining the origin of Wall Earth (壁上土) and the structural divergence between Geng Zi and Xin Chou.
- Lan Tai Miao Xuan (蘭臺妙選 · Song Dynasty): Poetic imagery and Nayin resonance conditions for Wall Earth.
- Di Tian Sui Chan Wei (滴天髓闡微 · Liu Bo-wen & Ren Tie-qiao): Canonical verses on Heavenly Stem Geng (“庚金帶煞，剛健為最，得水而清，得火而銳”) and Earthly Branch Zi.
- Qiong Tong Bao Jian (窮通寶鑑 · Yu Chun-tai): Twelve-month Climate-Regulating Useful God (Tiao Hou Yong Shen) selection for Stem Geng.
- Zi Ping Zhen Quan (子平真詮) & Yuan Hai Zi Ping (淵海子平): Doctrines of the Twelve Stages of Growth (Tử (Stillness)), Hidden Stems & Seated Ten Gods (Hurting Officer (Hurting Officer (Shang Guan))), and Xun Void (Chen, Si (Chen, Si)).
Core Methodological Principle: One pillar never defines an entire life. All eight characters must be weighed together. Any analysis of the birth-year Nayin (Wall Earth) or the standalone Geng Zi 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.

Rank #37 of 60. Belongs to the Jia Wu Xun. In classical Chinese and Vietnamese sexagenary horology, Geng Zi (庚子, Gēng Zǐ) unites Heavenly Stem Geng (Yang Metal) with Earthly Branch Zi (Yang Water, Zodiac Rat), placing its Xun Void at Chen, Si (Chen, Si) and carrying the Nayin destiny of Wall Earth (Wall Earth (Bi Shang Tu), Refined plaster and architectural masonry shielding halls and chambers from winter wind).
Earth Element destiny. Nayin Wall Earth (Wall Earth (Bi Shang Tu)). Individuals born in the Geng Zi year correspond to Gregorian solar years 1900, 1960, 2020 (measured strictly from the Start of Spring / Lichun solar term); according to the Ming-dynasty compendium San Ming Tong Hui, they embody 壁上土 (Refined plaster and architectural masonry shielding halls and chambers from winter wind) with unmistakable inner resilience.
Seated on Hurting Officer (Hurting Officer (Shang Guan)). Occupies the Tử (Stillness) stage. Beneath Earthly Branch Zi of the Geng Zi pillar lie the hidden stems Gui (Main Qi, Hurting Officer (Hurting Officer (Shang Guan))); when referenced against Heavenly Stem Geng, the primary seated qi is Hurting Officer (Hurting Officer (Shang Guan)) (傷官), establishing a Luminous Output Venting (Refined Output Brilliance (Jing Hua Xie Xiu)) structural dynamic.
