I. Brief Overview of Geng Xu Day Master · Ten Gods Quick Reference · Pattern Tendencies
Day Pillar Structure: Geng Metal as Day Master, seated on Xu Earth. Xu is dry earth, internally storing Xin Metal (Companion/Robber), Ding Fire (Official/Killing Star), Wu Earth (Seal/Companion), also a Fire Vault — hidden fire within earth can refine or burn metal; critical lies in precise balance of dryness-moisture and heat level. Ancient theory on Geng Metal: weak in Spring-Summer, favors wet earth like Chou or Chen for nourishment; strong in Autumn, purified by Ren Water, shaped by Ding Fire; cold in Winter, needs Fire to warm.
Xu Earth Adjustment Key Points: Xu belongs to dry vault; Fire opens the vault for forging, but excessive dryness without Water makes metal brittle; too much Water extinguishes Fire and loses forging power. Best when Fire-Water mutually assist.
Personality Baseline: Geng Metal is rigid, decisive. Seated on Xu with hidden Fire, one tends to be “principled and backbone-strong,” but in overly dry configurations may appear stubborn and impatient. If refined by Ding Fire and cleansed by Ren/Gui Water, becomes “rigid yet flexible,” gaining grace and grandeur.
Ten Gods Quick Reference (depends on overall strength)
- Wealth Stars: Wealth facilitates smooth interaction, controls Robbers — beneficial for career and collaboration; excessive Wealth with weak body leads to being driven by KPIs.
 - Official/Killing Stars: Ding Fire in Xu roots at body; strong body paired with Seal/Food God controls Killing Star, transforms pressure into authority. Strong Killing Star with weak body and no Seal brings stress and constraints.
 - Seal Stars: Wu/Ji Earth as Seal nourishes Geng Metal, aids education and resources, but excessive dry Seal without Water-Fire leads to stagnation.
 - Food/Injury Stars: Relieve rigidity, bring creativity and expression; however, if “Injury Star meets Official” with weak body, fame and fortune are obstructed.
 
Common Pattern Paths
- Killing-Seal Mutual Generation: Ding Fire (Killing Star) in Xu transformed by Seal Earth, Geng Metal strong enough to handle responsibility — authority secured.
 - Food God Controls Killing / Wealth Transforms Robber: Food/Injury releases Geng’s rigidity, then controls Ding Fire in Xu; or Wealth mobilizes cooperation, reduces internal Robber conflict.
 - Adjustment Priority: Geng Xu most fears “excessive dryness” — supplement Water to ignite Fire, moist earth to nourish Metal is the core principle.
 
II. Geng Xu Born Across Four Seasons: Career, Marriage, Health (Seasonal Summary)
Note: Below analyzes by seasonal month commands (Spring: Yin/Mao/Chen; Summer: Si/Wu/Wei; Autumn: Shen/You/Xu; Winter: Hai/Zi/Chou) as one season per section; actual judgment still requires full chart strength, stem emergence, and luck cycle alignment.
Spring (Yin, Mao, Chen)
Adjustment Key: Spring Wood dominates, suppressing Metal — Geng Metal weak; favors Bing/Ding Fire for forging, moist earth for support, plus a touch of Ren Water for flow. Excess Wood without Fire → “Wood overwhelms Metal”; with Fire-Earth → “refined into vessel.”
- Career Fortune: Suited for system-based professions (legal, risk control, engineering standards, compliance audit) or brand/product quality management. Weak body should avoid confrontation, rely on Seal (experience/team) and processes; those with Fire-Seal easily rise.
 - Marriage Fortune: Heavy Spring Wood implies external expectations; male命 wealth stars float (busy work, neglect home), female命 official/killing stars press body → picky partners. Proper adjustment (Fire-Earth protection) → partner practical and reliable.
 - Health Fortune: Weak Geng Metal cut by Wood → prone to neck/shoulder/joint/tooth issues; heavy Spring dampness → weak spleen-stomach. Warm Yang, protect spleen, regular作息 advised.
 
Summer (Si, Wu, Wei)
Adjustment Key: Fire forges Metal — opportunity for fame/fortune; but Xu/Wei are dry earth, most忌 excessive dryness without Water — Metal easily cracks. Requires Ren/Gui Water to moderate, preventing Fire from burning Metal.
- Career Fortune: Excels in leadership/management, military/police/inspection, energy manufacturing, equipment maintenance — “fire-forge-metal” industries; further gains Water Wealth luck → open markets, lead teams. Extreme Fire without Water → short-term brilliance, lacks endurance.
 - Marriage Fortune: Strong Official/Killing (Ding Fire); strong body type → “pressure drives motivation,” partner supportive; weak body → emotional impatience, harsh speech. Use Food/Injury or Seal to relieve, improves communication.
 - Health Fortune: Hot, dry earth → prone to heatiness, dry skin, dry gut; avoid spicy/alcohol, moderate hydration is key. Seek moderation.
 
Autumn (Shen, You, Xu)
Adjustment Key: Metal in command — Geng Metal best shaped; still requires Ding Fire accent and Ren Water cleansing to achieve “rigid yet cultured.” Autumn Metal with Xu — caution against excessive dryness, favor slight moist earth for smooth flow.
- Career Fortune: Excels in financial risk control, auditing, legal litigation, metal/precision manufacturing; if pattern shows Killing-Seal Mutual Generation, even better for authority positions, enforcing rules.
 - Marriage Fortune: Strong Autumn Metal → rational; if Wealth Star (Wood) scarce → emotional expression overly logical or “dull.” With Food God or emerging Ding Fire at Hour, interactions warmer.
 - Health Fortune: Metal’s killing energy → prone to dry lungs/large intestine, nasal sensitivity; moisturize lungs, avoid late nights and high caffeine.
 
Winter (Hai, Zi, Chou)
Adjustment Key: Cold Water cools Metal — though “pure,” easily “brittle.” Priority: Bing/Ding Fire to warm; secondarily, moist earth to carry Metal. If only Water-Seal present, becomes overly rigid and unusable.
- Career Fortune: Suitable for strategic planning, data risk control, legal compliance/internal control; must have “Fire-driven visibility” — publishing, speaking, branding — to showcase ability.
 - Marriage Fortune: Winter emotion reserved, slow to warm; if luck cycle reveals Fire, relationships accelerate. Wealth Star emerging → high family resource investment;忌 Robber conflict over Wealth → quarrels.
 - Health Fortune: Cold constitution → protect kidneys, lower back, joints; movement warms, prioritize regular exercise and early sleep.
 
III. Summary | Seasonal Preferences and Taboos
- Geng Xu General Adjustment Principle: Fire indispensable, Water not excessive, Earth preferably moist. Geng Metal favors wet earth like Chou/Chen; most忌 dry earth Xu/Wei without Water →易脆. Autumn-born with Ding Fire + Ren Water → clear and usable.
 - Spring: Strengthen body, support Metal; first take Bing/Ding + moist earth to stabilize, then discuss Wealth/Official.
 - Summer: Fire strong and dominant, add drop of Water to moderate;忌 excessive dryness damaging Metal.
 - Autumn: Most favorable for shaping; accent Fire, cleanse with Water, avoid excessive rigidity.
 - Winter: Warm first, then moisten; first supplement Fire, then consider Seal Earth for carrying.
