Tong Shu 通書 Daily Almanac: 2026-10-20 — 执 (守成之意。 宜：纳采、嫁娶、动土、入殓。 忌：入宅、开市。) Day | iGeomancy
Opening Verdict
Today, 2026-10-20 (Lunar 2026/9/11), presents a dual cosmic influence: the 执 Jianchu deity (Execution Day) mandates decisive action, yet the 勾陈 Value Deity (Black Path) warns against hasty ventures. This is not a day for new beginnings—avoid business openings (开市), property moves (入宅), or high-stakes deals. Instead, channel the Fire Rabbit energy toward maintenance: finalize contracts, resolve disputes, or complete renovations. For Singaporeans, this means prioritizing HDB repair approvals over BTO signings, settling legal matters before Friday, and postponing financial negotiations until the auspicious 子时 (23:00–01:00). The 黑道 (Black Path) energy demands caution—guard against impulsive decisions that may lead to ‘beginning with joy and ending in sorrow’ (《Tong Shu》).
Today’s Day Pillar 今日日柱
Day Pillar 丁卯 (Fire Rabbit) anchors today’s energy. The Heavenly Stem 丁 (Yin Fire) signifies adaptable, creative energy, while the Earthly Branch 卯 (Wood) represents growth and flexibility. Hidden stems reveal: Year 午 (Fire) contains 丁 Fire (main) and 己 Earth (mid); Month 戌 (Earth) holds 戊 Earth (main), 辛 Metal (mid), and 丁 Fire (residual); Day 卯 contains 乙 Wood (main). The Na Yin (Sound Element) is 炉中火 (Furnace Fire), indicating intense, transformative energy—like molten metal cooling into form. Elementally, this clashes with Month 戊戌 (Earth Dog), as Fire consumes Earth (Fire→Earth), but harmonizes with Year 丙午 (Fire Horse), producing a cooperative 卯戌合火 (Wood-Earth Fire Combination). This explains why today favors legal actions (动土) but forbids business openings (开市): Fire consumes Earth, weakening financial outcomes (纳财) despite auspicious stars.
建除神 Jianchu Guide — 执 (守成之意。 宜：纳采、嫁娶、动土、入殓。 忌：入宅、开市。)
执 (Zhí) means ‘to hold firm’ or ‘to maintain.’ The Jianchu deity for this day dictates that energy must be channeled into decisive execution—confronting problems directly rather than initiating new ventures. Historically, this was the day to settle debts (not collect them), finalize lawsuits (not file them), or complete construction (not start it). The classical text states: ‘执者，守成之意。宜：纳采、嫁娶、动土、入殓。忌：入宅、开市。’ (Execution day: maintain status quo. Favorable for: engagement, marriage, construction, burial. Forbidden: moving into new homes, business openings.) In modern Singapore, this means: HDB homeowners should schedule repair work (not renovation bids), CBD executives should resolve pending disputes (not launch new projects), and SME owners should pay outstanding invoices (not seek new clients). The 丙午 Year Pillar (Fire Horse) intensifies this—Fire fuels decisiveness but risks burnout. Avoid ‘grand openings’ (开市) as they invite financial loss (劫财 energy at 午时), but use the day to ‘move through’ problems (入殓 for burial, symbolizing closure of old matters).
今日值神与神煞 Twelve Value Deities & Shen Sha Spirits
The Value Deity is 勾陈 (Gōu Chén), a Black Path deity (黑道凶神) associated with gossip, entanglements, and unfinished projects. As《Tong Shu》warns: ‘Anything undertaken during this hour will have a start but no proper end—beginning with joy and ending in sorrow.’ For Singaporeans, this means avoiding social media announcements (e.g., ‘New business open!’) as they may lead to client disputes. Favorable spirits (吉神) include 天恩 (Heavenly Grace), 六合 (Six Harmonies), and 圣心 (Sacred Heart), ideal for collaborative tasks like team meetings or family gatherings. Taboo spirits (凶神) include 大时 (Great Hour), 大败 (Great Defeat), and 咸池 (Fragrant Pool), which amplify conflict and financial loss. Today, 大败 is particularly potent during 05:00–07:00 (卯时), making morning commutes risky—avoid scheduling client calls before 9 AM. The 财神 (Wealth God) in 西南 (southwest) offers protection, but 勾陈’s Black Path energy nullifies this if you ignore the 卯时 warning. For CBD executives, this means postponing salary negotiations (大败 energy) but using 丙午 (rob wealth) hour (11:00–13:00) for cost-cutting measures (not revenue generation).

今日风水方位与奇门生门 Feng Shui Compass Directions & Qi Men Life Gate
Activate 西南 (southwest) for 财神 (Wealth God) during 23:00–01:00 (子时) to secure financial outcomes. For HDB units, position your desk facing southwest when reviewing budgets. 喜神 (Joy God) in 正南 (southeast) enhances relationship talks—ideal for family gatherings or client dinners. 福神 (Blessing God) in 正东 (east) supports recovery: place healing crystals (amethyst) here for immune support. 生门 (Life Gate) in 正西 (west) activates business momentum—use this for signing contracts (but avoid 15:00–17:00 due to 伤官 energy). Avoid facing 西 (west) for 24 hours (煞方 energy), as it weakens all endeavors. Singapore tip: For condo offices, set up a red (fire) lamp in southwest to amplify 财神 energy. Dietary tip: Consume cooling foods (mung beans) to counter 炉中火 (Furnace Fire) energy.
今日宜忌总览 Modern Singapore Activity Guide — Do and Avoid
✓ AUSPICIOUS TODAY (宜): Finalize HDB renovation contracts (动土), settle legal disputes (入殓), or schedule family gatherings (会亲友). For CBD leaders: Use 03:00–05:00 (寅时) for performance reviews (正官 energy). For SMEs: Pay suppliers (纳财) during 23:00–01:00 (子时) to avoid 勾陈 gossip. Do NOT use today for new business openings (开市)—the Year Pillar 丙午 (Fire Horse) will consume your financial foundation (Fire→Earth consumption).
✗ AVOID TODAY (忌): Do NOT open new shops (开市), move into HDB flats (入宅), or cut hair (剃头)—this shortens lifespan (Lunar Day 1 vulnerability). Avoid medical procedures (especially brain/head surgeries, as 炉中火 energy affects the brain). For CPF contributors: Do NOT initiate new investments (纳财)—use 23:00–01:00 (子时) only for paying existing debts. The 28 Mansions (尾火虎) confirms: ‘The Tail Lodge is beneficial for closure, not new beginnings.’
农历廿八星宿与生活月相 28 Lunar Mansions & Lifestyle Timing
Today falls under 尾火虎 (Tail Fire Tiger), the 6th Lodge of the constellation. Fire (Mars) energy dominates, symbolizing ‘decisive action.’ For Singaporeans, this means: Mental focus is high (avoid procrastination), but emotional balance requires cooling (no spicy food—risk of 炉中火 imbalance). Business posture: Negotiate firmly but avoid aggression (Fire consumes Earth). Health: Immune system vulnerable—prioritize rest over work. Haircut taboo: Do NOT cut hair (Lunar Day 1 rule: ‘shortens lifetime’). Instead, use 03:00–05:00 (寅时) for quiet reflection. Wellness tip: Drink chrysanthemum tea to counteract Fire energy (Mars energy). For MRT commuters: Avoid 05:00–07:00 (卯时) due to 七杀 energy causing delays.
