☯ Executive Summary for Researchers & Practitioners (Core Principles)
Xuan Kong Flying Star Feng Shui (玄空飛星 — Huyền Không Phi Tinh) is the pinnacle of classical Li Qi (理氣 — Dynamic Qi Configuration) geomancy, modeling architectural space as a four-dimensional spatio-temporal vector field (3D Compass Space × 180-Year Cosmic Time); whereas Eight Mansions Feng Shui establishes static personal compatibility, Xuan Kong Flying Stars explains why the exact same building generates extraordinary wealth in one decade and sudden illness in the next—and why events trigger in a specific year and month:. Timing is the trigger.
- Celestial Mechanics of the 180-Year Cycle (San Yuan Jiu Yun 三元九運): Each 20-year Period corresponds to the astronomical Great Conjunction of Jupiter (TJ ≈ 11.862 years) and Saturn (TS ≈ 29.457 years), which align every 19.859 ≈ 20 years. Three conjunctions form a 60-year Cycle (Yuan — matching the Sexagenary Jiazi cycle), and nine conjunctions across the Nine Luo Shu Palaces complete the 180-year Grand Cycle.
- Four-Layer Star Matrix (Period – Mountain – Facing – Annual/Monthly): Each of the nine palaces hosts a Period Star (Base Heaven Qi), a Mountain Star (governing people, health, and progeny), a Facing Star (governing wealth, cashflow, and career), and visiting Annual/Monthly Guest Stars (temporal triggers).
- 24-Mountain Yin–Yang Polarity & Xia Gua vs. Ti Gua Algorithms: Whether a Mountain or Facing star flies forward (+ Yang) or in reverse (- Yin) along the Luo Shu path is dictated by the Three Cycles Dragons (Earth – Heaven – Human) and the Two-Fold Yin–Yang Partition (Liang Pian Yin Yang). When a compass reading skews beyond ± 3° ext–4.5° from a mountain's center, the practitioner must switch from a Direct Chart (Xia Gua 下卦) to a Replacement Star Chart (Ti Gua 起星替卦).
- The Unique Mathematical Reality of Period 9 (2024–2043): Because the number 9 (Li Fire) sits in the South, not a single one of the 24 mountains in Period 9 produces a Direct "Prosperous Mountain, Prosperous Facing" chart—every Period 9 chart is either Double Stars at Facing or Double Stars at Sitting!
Chapter 1. Classical Lineage & Transmission: From Patriarch Yang Yunsong to Jiang Dahong, Zhang Zhongshan & Shen Zhureng
Physics backs this up. For over a thousand years, Xuan Kong Flying Star Feng Shui was guarded as an esoteric imperial art transmitted orally from master to disciple under solemn oaths of secrecy. When standing with a Luo Pan before centuries-old ancestral halls and modern corporate towers, I am continually struck by the mathematical rigor preserved across four monumental eras of transmission:
1.1. Tang Dynasty Imperial Origins: Guo Pu & Patriarch Yang Yunsong (834–900 CE)
The term Feng Shui originates in the Book of Burial (Zang Shu 葬書) by Guo Pu (郭璞, 276–324 CE): "Qi rides the wind and scatters, but is retained when encountering water." In 880 CE, when the Huang Chao rebellion sacked the Tang capital of Chang'an, the imperial court geomancer Yang Yunsong (楊筠松 — Master Yang Rescuing the Poor, 834–900 CE) carried the secret astronomical manuscripts from the Imperial Observatory to Ganzhou in Jiangxi Province; there he composed the three foundational classics of Xuan Kong:. Keep it simple.
- Qing Nang Ao Yu (青囊奧語 — Esoteric Words of the Green Satchel): Opens with the cryptic verse that encodes the Replacement Star (Ti Gua) algorithm: "Kun Ren Yi, Ju Men emerges from the head; Gen Bing Xin, every place is Po Jun; Xun Chen Hai, all are Wu Qu positions; Jia Gui Shen, Tan Lang walks straight ahead!"
- Tian Yu Jing (天玉經 — Classic of the Jade Heaven): Expounds the Three Cycles Dragons (Heaven, Earth, Human), the Parent String (Fu Mu San Ban Gua), and the Void Line taboos.
- Du Tian Bao Zhao Jing (都天寶照經 — Precious Mirror Classic of the Imperial Heaven): Reveals the formulas for Seven-Star Robbery (Qi Xing Da Jie) and the Castle Gate (Cheng Men Jue).
1.2. Early Qing Renaissance: Jiang Dahong & Di Li Bian Zheng
That changes everything. During the Ming–Qing transition, Jiang Dahong (蔣大鴻, 1616–1714) received the authentic Xuan Kong transmission from the Daoist master Wu Ji Zi. In his magnum opus Di Li Bian Zheng (地理辨正 — Rectifying the Principles of Geomancy), Jiang swept away Centuries of spurious Five-Phase fabrications and restored the primacy of the Luo Shu Nine Qi, though he deliberately veiled the step-by-step chart-casting rules in poetic riddles.
1.3. The Wu Chang School (Zhang Zhongshan) & Shen Zhureng's Great Decryption
In the Jiaqing–Daoguang era of the Qing Dynasty, Zhang Zhongshan (章仲山) of Wuxi founded the Wu Chang School (無常派 — School of Impermanence), recording dozens of verified residential and yin-house audits in Yin Yang Er Zhai Lu Yan (陰陽二宅錄驗); in the late 19th century, the brilliant scholar Shen Zhureng (沈竹礽, 1849–1906) paid 1,000 taels of silver to copy the private casebooks of Zhang Zhongshan's descendants. Through years of mathematical deduction, Master Shen cracked the entire cipher of the Wu Chang lineage, culminating in the publication of Shen Shi Xuan Kong Xue (沈氏玄空學 — Master Shen's Study of Xuan Kong)—the bible of modern Flying Star Feng Shui. Qi never lies.
Chapter 2. Celestial Mechanics of the 180-Year Cycle (San Yuan Jiu Yun) & Direct vs. Indirect Spirit
Never guess the degree. Why is every Xuan Kong Period exactly 20 years, every Cycle 60 years, and the Grand Cycle 180 years? Look to the sky. Time is real. Planets move. It is pure planetary astrophysics.
2.1. The Jupiter–Saturn Great Conjunction Cycle (19.859 ≈ 20 Years)
Ancient Chinese astronomers tracked the two most massive gas giants of our solar system: Jupiter (Sui Xing 歲星, orbital period TJ ≈ 11.862 years) and Saturn (Zhen Xing 鎮星, orbital period TS ≈ 29.457 years); their synodic conjunction period is given by celestial mechanics:. Here is the catch.
Classics are explicit here.
Every 20 years, Jupiter and Saturn align; every 60 years (3 imes 20 = 1 Cycle / Yuan), their conjunction returns to the same ecliptic sector, completing one 60-year Sexagenary Jiazi cycle; and every 180 years (9 imes 20 = 3 Cycles / 9 Periods), all nine Big Dipper / Luo Shu Qi phases complete a full revolution!. Look at the site first.
2.2. Direct Spirit (Zheng Shen 正神) vs. Indirect Spirit (Ling Shen 零神) in Period 9
Do not conflate the two. In Xuan Kong, no star is permanently good or bad—"Timely stars are noble; untimely stars turn malicious." In Period 9 (2024–2043), Nine Purple (9) is the Supreme Ruling Star (Wang Qi), One White (1) and Two Black (2) are Future Sheng Qi stars, and Eight White (8) is Retreating Qi. The native palace of the Ruling Star—Due South (Li 9)—is the Direct Spirit (Zheng Shen), which demands solid elevation and mountain support; its opposite palace summing to 10 (9 + 1 = 10)—Due North (Kan 1)—is the Indirect Spirit (Ling Shen), where external water (rivers, lakes, swimming pools, or major road intersections) triggers rapid wealth.
Chapter 3. Decoding the 24 Mountains, Three Cycles Dragons (San Yuan Long) & Two-Fold Yin–Yang Polarity
The 360° compass ring is divided into 8 trigrams (45° each) and 24 Mountains (15° each); counter-clockwise within every 45° palace sit three mountains: the Earth Dragon (Di Yuan Long 地元龍 — 1st mountain), the Heaven Dragon (Tian Yuan Long 天元龍 — 2nd mountain), and the Human Dragon (Ren Yuan Long 人元龍 — 3rd mountain). Field audits prove this.
Chapter 4. Chart-Casting Algorithms: Direct Chart (Xia Gua 下卦) & Replacement Stars (Qi Xing Ti Gua 起星替卦)
The compass never flatters. When the building's axis sits within the central 9° of a mountain (skewing less than ± 3° ext–4.5°), cast a Direct Chart (Xia Gua): place the Period number in the Center Palace and fly forward; take the Period Star in the Sitting Palace as the Mountain Star and the Period Star in the Facing Palace as the Facing Star; then check the Yin/Yang polarity of the corresponding Dragon (Earth, Heaven, or Human) inside the native Luo Shu palace of that star number N to fly forward (+) or in reverse (-).
However, when the compass line skews beyond ± 3° ext–4.5° toward an adjacent mountain (a straddling or Jian Xiang orientation), you must apply Yang Yunsong's Replacement Star Algorithm (Ti Gua) from the Qing Nang Ao Yu:. Measure twice.
| Period Star in Sitting/Facing (N) | Native Luo Shu Palace | 3 Mountains in Native Palace | Replacement Star Number (Ti Xing) | Classical Formula Reference (Qing Nang Ao Yu) |
|---|---|---|---|---|
| Star 1 | ☵ Kan (North) | Ren · Zi · Gui | Ren → 2 | Zi → 1 | Gui → 1 | "Kun Ren Yi, Ju Men (2) emerges" — Ren replaces with 2; Zi and Gui remain 1. |
| Star 2 | ☷ Kun (Southwest) | Wei · Kun · Shen | Wei → 2 | Kun → 2 | Shen → 1 | "Jia Gui Shen, Tan Lang (1) walks" — Shen replaces with 1; Wei and Kun remain 2. |
| Star 3 | ☳ Zhen (East) | Jia · Mao · Yi | Jia → 1 | Mao → 2 | Yi → 2 | All three Zhen mountains change: Jia replaces with 1; Mao and Yi replace with 2. |
| Star 4 | ☴ Xun (Southeast) | Chen · Xun · Si | Chen → 6 | Xun → 6 | Si → 6 | "Xun Chen Hai, all are Wu Qu (6)" — All three Xun mountains replace with 6. |
| Star 5 | ☯ Center Palace | (Follows House Sitting/Facing) | Remains 5 | Center 5 has no replacement star; it stays 5 and follows the house mountain's Yin/Yang. |
| Star 6 | ☰ Qian (Northwest) | Xu · Qian · Hai | Xu → 6 | Qian → 6 | Hai → 6 | All three Qian mountains belong to Wu Qu Metal (6) and remain 6. |
| Star 7 | ☱ Dui (West) | Geng · You · Xin | Geng → 7 | You → 9 | Xin → 7 | Geng and Xin remain 7 (Po Jun); You replaces with 9 (You Bi Fire). |
| Star 8 | ☶ Gen (Northeast) | Chou · Gen · Yin | Chou → 7 | Gen → 7 | Yin → 9 | "Gen Bing Xin, all are Po Jun (7)" — Chou and Gen replace with 7; Yin replaces with 9. |
| Star 9 | ☲ Li (South) | Bing · Wu · Ding | Bing → 7 | Wu → 9 | Ding → 9 | Bing replaces with 7 (Po Jun); Wu and Ding remain 9 (You Bi). |
Chapter 5. The Four Classic Configurations & Form-Reversal Remedies
Context rules all. Every Flying Star chart falls into one of four structural archetypes governed by the golden maxim: Mountain governs People; Water governs Wealth (山管人丁，水管財):
Chapter 6. Four Supreme Special Formations: Parent String, Sum-of-Ten, Seven-Star Robbery & Castle Gate
Classical Xuan Kong prizes four extraordinary formations capable of transcending single-period limitations:
- Parent String Chart (Fu Mu San Ban Gua 父母三般卦): Every one of the nine palaces contains one of the three triad strings
1-4-7,2-5-8, or3-6-9(combining Period, Mountain, and Facing stars), linking Upper, Middle, and Lower Cycle Qi into an unbroken circuit. - Full-Chart Sum of Ten (Quan Pan He Shi 全盤合十): In all nine palaces, either Period + Mountain = 10, Period + Facing = 10, or Mountain + Facing = 10, creating total cyclic harmony across the building.
- Northern Dipper Seven-Star Robbery (Bei Dou Qi Xing Da Jie 北斗七星打劫): In a Double Stars at Facing chart, when the Facing Stars of the Li (South) – Zhen (East) – Qian (Northwest) triangle (True Robbery) or the Kan (North) – Xun (Southeast) – Dui (West) triangle (Borrowed Robbery) form a
1-4-7,2-5-8, or3-6-9Parent String, and all three sectors are open and connected indoors, the property harnesses prosperous Qi across all three cycles!
Chapter 7. The Xuan Kong Purple-White Script (Zi Bai Jue 紫白訣): Key Star Combinations & Annual Timing
Every palace contains a Mountain Star – Facing Star pair whose Five-Phase interaction scripts the events in that room, while the visiting Annual and Monthly Flying Stars act as the temporal detonator:. Form comes first.
| Star Pair | Classical Name | Five-Phase Dynamics | Clinical Manifestation & Field Activation / Remedy Protocol |
|---|---|---|---|
| 1 – 4 / 4 – 1 | Riding the Azure Clouds (Wen Chang Pair) | 1 Water nourishes 4 Wood | "Four and One in the same palace brings academic laurels." Supreme combination for scholarship, research, writing, and career promotion. Ideal for studies and executive desks. |
| 1 – 6 / 6 – 1 | Pre-Heaven Water & Metal | 6 Metal generates 1 Water (He Tu 1-6 Water) | Brings noble benefactors, executive authority, military/legal command, and clean financial growth. |
| 8 – 9 / 9 – 8 | Fire & Earth Joyous Union | 9 Fire generates 8 Earth | "Eight meeting the Purple Star brings double celebrations." Drives real-estate appreciation, marriage, childbirth, and rapid wealth in Period 9. |
| 9 – 1 / 1 – 9 | Water & Fire Completion (Sum of Ten) | 9 Fire + 1 Water = 10 | Unites the #1 Ruling Star (9) and #1 Future Sheng Qi Star (1) of Period 9. Generates breakthrough innovation, AI/tech wealth, and fame. |
| 2 – 5 / 5 – 2 | Two–Five Deadly Convergence | 2 Illness Earth + 5 Poison Earth | #1 Supreme Affliction! Triggers severe illness, tumors, surgery, and bereavement. Remedy: Heavy brass Wu Lou gourds, 6-rod brass wind chimes, strict quietude; never use red lights or dig here! |
| 3 – 7 / 7 – 3 | Piercing Heart Sha (Metal–Wood War) | 7 Metal chops 3 Wood | Triggers robbery, fraud, lawsuits, and limb/liver surgery. Remedy: Still Water (navy/black accents or saline water) to bridge Metal → Water → Wood. |
| 2 – 3 / 3 – 2 | Bullfight Sha (Dou Niu Sha) | 3 Wood clashes 2 Earth | Provokes fierce marital quarrels, litigation, and digestive ulcers. Remedy: Introduce Fire (warm lighting, red/burgundy rug) so Wood feeds Fire and Fire generates Earth. |
| 7 – 9 / 9 – 7 | Hui Lu Fire Hazard Combination | 9 Fire melts 7 Metal | Provokes electrical fires, cardiovascular emergencies, bleeding, and explosive temper. Remedy: Yellow Earth ceramics or yellow quartz crystals to bridge Fire → Earth → Metal. |
Chapter 8. Master Strategy for Lower Cycle Period 9 (2024–2043)
Cure the root cause. Since Li Chun on February 4, 2024, the world has entered Period 9 (2024–2043) governed by Nine Purple Fire (9). Master these three rules for Period 9 properties:
- All 24 Direct Charts in Period 9 are Double-Star Charts: Twelve orientations (Facing Bing, Geng, You, Xin, Xu, Qian, Hai, Gui, Chou, Gen, Yin, Chen) feature Double 9 Stars at the Front (Facing)—ideal for commercial and residential wealth provided there is an open Ming Tang buffered by an outer protective mountain/building ("Mountain beyond Water"). The opposite twelve orientations feature Double 9 Stars at the Rear (Sitting), requiring a rear courtyard, skylight, or water feature to unlock wealth.
- Top Golden Orientations of Period 9:
- Sitting Gen Facing Kun (NE to SW) & Sitting Kun Facing Gen (SW to NE): Full-chart Parent String (
1-4-7,2-5-8,3-6-9)! - Sitting Xun Facing Qian (SE to NW) & Sitting Si Facing Hai: Double 9 Stars at Facing combined with Li Palace Seven-Star Robbery across Li–Zhen–Qian!
- Sitting Zi Facing Wu & Sitting Gui Facing Ding (North to South): Full-chart Mountain–Facing Sum of Ten (He Shi)!
- Sitting Gen Facing Kun (NE to SW) & Sitting Kun Facing Gen (SW to NE): Full-chart Parent String (
- Period 9 Water Formula: Due North (Kan 1 — Indirect Spirit) is the supreme macro water sector of Period 9, while Due South (Li 9 — Direct Spirit) favors solid elevation.
Chapter 9. Renewing the Heaven Heart (換天心) & Integrating Eight Mansions with Flying Stars
For homes built in Period 7 (1984–2003) or Period 8 (2004–2023) whose vitality has waned after 2024, you have two clinical options:. Timing is the trigger.
- Option 1 — Activate the Natal 9 and 1 Facing Stars on Your Existing Chart (No Demolition): Locate the palaces hosting Facing Star 9 and Facing Star 1 on your Period 8 chart, and shift your active water feature, bright lighting, or main workspace into those palaces while toning down water in the retiring Star 8 palace.
- Option 2 — Renewing the Heaven Heart (Huan Tian Xin — Converting to a Period 9 Chart): Perform a synchronized 3-part renovation on an auspicious Period 9 date: (1) open a section of the roof/ceiling over the Center Palace to admit natural sky Qi and sunlight; (2) re-floor the central zone and refurbish the Main Gate; and (3) install a new stove and conduct a formal Period 9 move-in ceremony.
Chapter 10. Three Real-World Field Case Studies & 8 Scholarly FAQs
Activating Double Stars at Facing + Li Palace Seven-Star Robbery (Sitting Xun Facing Qian, Period 9)
Physics backs this up. Field Diagnosis: This software firm moved into a newly built Period 9 building Sitting Xun Facing Qian (314.5°). The chart features Double 9 Stars at the Northwest Entrance and a classic Li–Qian–Zhen Seven-Star Robbery structure. However, the Northwest entrance faced a wide, windy intersection with zero protective barrier (causing the Mountain Star 9 to "drown"), while the Due South (Li) corner was locked up as a dark storage room—blocking the Robbery triangle.
Remedial Protocol: (1) Inside the Northwest lobby, we installed an infinity water wall backed by a 2.2m solid marble feature wall bearing the company emblem—creating "Mountain Beyond Water" so the water activated Facing Star 9 while the stone wall anchored Mountain Star 9; (2) We cleared the Due South (Li) storage room into a bright glass boardroom connected directly to the Due East (Zhen) engineering floor; within three quarters, the company's AI software revenue grew 2.4×. Keep it simple.
Neutralizing a 2–5 Deadly Convergence at the Gate & Renewing the Heaven Heart into Period 9
That changes everything. Field Diagnosis: Built in 2016 (Period 8) Sitting Gen Facing Kun, this villa suffered from a Reversed Mountain & Water Period 8 chart where the Southwest main entrance hosted the lethal Mountain 2 – Facing 5 (Two–Five Deadly Earth) pair—right where the owner had dug a large Koi pond! Between 2022 and early 2024, the churning water in Southwest amplified the 2-5 affliction, triggering stomach surgery and heavy equity losses.
Remedial Protocol: (1) We immediately drained the Southwest pond and placed heavy bronze Wu Lou gourds to exhaust the 2-5 Earth; (2) In June 2024, we executed a full "Renewing the Heaven Heart" renovation—opening the central skylight for seven days, replacing the kitchen stove, and re-consecrating the main gate; converted into a Period 9 Sitting Gen Facing Kun chart, all nine palaces transformed into a Parent String (1-4-7, 2-5-8, 3-6-9) with Double 9 Ruling Stars at the Southwest Entrance! Both the owner's health and investment portfolio rebounded strongly by late 2024. Qi never lies.
Correcting a Critical Misdiagnosis Between Direct Chart (Xia Gua) & Replacement Chart (Ti Gua)
Never guess the degree. Field Diagnosis: A previous consultant had used a mobile app to cast a Period 9 Direct Chart (Sitting Bing Facing Ren), alarming the owner that the North storefront hosted an inauspicious 5-4 pair. When I measured the storefront with a 36-ring classical Luo Pan, the axis read exactly 351.8°—sitting just 0.7° from the Ren–Zi boundary (352.5°), skewing 4.3° from Ren's centerline!
Remedial Protocol: At 351.8°, the property requires a Replacement Star Chart (Ti Gua)! In Period 9, the Sitting Palace (Li) holds Period Star 4 (Xun), which replaces with Star 6 (Wu Qu Metal flying forward) under the rule "Xun Chen Hai, all are Wu Qu 6"; consequently, the North storefront actually hosts Mountain Star 2 – Facing Star 9 (Ruling Nine Purple Fire at the Facing!) rather than 5-4! By activating the North entrance with warm lighting and an open reception foyer, the owner's jewelry showroom achieved record opening-quarter sales. Here is the catch.
8 Frequently Asked Scholarly & Practical Questions (FAQ)
1. Does a house built in Period 8 (2004–2023) automatically switch to a Period 9 chart in 2024?
Classics are explicit here. Answer: No. A building's natal Flying Star chart is sealed when its roof is completed and residents first move in. After February 4, 2024, a Period 8 house retains its Period 8 star positions, but the qi quality of the stars shifts: Star 8 becomes Retreating Qi, while Star 9 on that Period 8 chart becomes the new Ruling Emperor Star. Only a major Renewing the Heaven Heart renovation converts the natal chart to Period 9.
2. Why are there ZERO Prosperous Mountain, Prosperous Facing direct charts in Period 9 (2024–2043)?
Answer: When 9 enters the Center Palace, the two palaces along every axis that receive Star 9 and Center Star 5 share identical Yin–Yang flight polarities under the Two-Fold Yin–Yang rule; as a result, the Mountain 9 and Facing 9 stars always fly to the same end of the building—producing 12 Double Stars at Facing charts and 12 Double Stars at Sitting charts. Look at the site first.
3. When do we cast a Direct Chart (Xia Gua) versus a Replacement Star Chart (Ti Gua)?
Do not conflate the two. Answer: Each of the 24 mountains spans 15°. If the compass axis falls within the central 9° (within ± 3° ext–4.5° of the mountain's center), cast a Direct Chart (Xia Gua). If the axis skews into the outer 3° border zone toward an adjacent mountain, cast a Replacement Star Chart (Ti Gua).
4. How do we remedy a Reversed Mountain and Water (Shang Shan Xia Shui) chart without demolition?
Answer: Use Form Reversal (Shou Shan Chu Sha): place a solid screen wall, tall evergreens, or rockery at the front facing palace to anchor the visiting Ruling Mountain Star, and open a rear courtyard, skylight, back entrance, or circulating water feature at the rear sitting palace to activate the visiting Ruling Facing Star. Field audits prove this.
5. What is the exact Five-Phase remedy for the 2–5 and 3–7 star combinations?
The compass never flatters. Answer: Always use Five-Phase Exhaustion or Bridging rather than direct clashing: (1) For 2-5 (Illness & Poison Earth), use heavy Metal (brass Wu Lou gourds, 6-rod brass wind chimes, six-emperor coins) so Earth drains into Metal; (2) For 3-7 (Metal clashing Wood), use still Water (dark blue/black accents or saline water) so Metal feeds Water and Water nourishes Wood.
6. Where are the Direct Spirit and Indirect Spirit in Period 9 (2024–2043)?
Answer: In Period 9, Due South (Li 9) is the Direct Spirit (Zheng Shen)—requiring high ground or tall buildings and avoiding large water bodies; its opposite Sum-of-Ten partner, Due North (Kan 1), is the Indirect Spirit (Ling Shen)—where lakes, rivers, pools, or busy road junctions trigger explosive wealth. Measure twice.
7. What three conditions are required to activate Seven-Star Robbery (Qi Xing Da Jie)?
Context rules all. Answer: (1) The natal chart must be Double Stars at Facing; (2) The Facing Stars in the Li–Zhen–Qian triangle (True Robbery) or Kan–Xun–Dui triangle (Borrowed Robbery) must form a Parent String (1-4-7, 2-5-8, or 3-6-9); and (3) All three sectors must be open, clean, and aerodynamically connected indoors.
8. How do Annual and Monthly Flying Stars interact with a building's natal chart?
Answer: The natal Mountain and Facing stars are the Host Stars (defining what can happen in a room), while the Annual and Monthly stars are the Guest Stars (defining when it triggers); every year before Li Chun (~February 4th), place brass cures in the sectors visited by Annual Five Yellow (5) and Two Black (2), and activate the sectors where Annual 9 or 1 meets an auspicious natal Facing Star.
