The Art of Incoming and Outgoing Flow
Mastering the Flow
In classical Feng Shui, "Mountain governs People, Water governs Wealth" (山管人丁水管財). Water methods focus on the precise alignment of incoming water (Lai Shui) and outgoing water (Qu Shui). These formulas are considered the "Secrets of the Chamber" for generating prosperity.

🐉 Long Men Ba Ju (Dragon Gate Eight Formations)
Also known as **Qian Kun Guo Bao** (乾坤國寶), this is the definitive San Yuan water system. It emphasizes the relationship between the Early Heaven (XT) and Later Heaven (HT) trigram positions.
Xian Tian Position (先天位)
Governs health and people. Incoming water here is auspicious; outgoing water leads to population decline.
Hou Tian Position (後天位)
Governs wealth and money. Incoming water here brings financial gain; outgoing water leads to loss.

📊 Comparison of Classical Water Methods
Chinese Feng Shui has developed multiple water analysis systems over its 2,000+ year history. Each approaches the fundamental question — "How does water affect this site?" — from a different theoretical lens.
| Method | Chinese | School | Core Logic | Time-Dependent? | Best Application |
|---|---|---|---|---|---|
| San He Water | 三合水法 | San He (三合) | 12 Growth Stages (十二長生) mapped to water flow direction relative to Sitting | No — fixed by landscape | Rural sites, burial, large estates |
| Long Men Ba Ju | 龍門八局 | San Yuan (三元) | Early Heaven ↔ Later Heaven trigram mapping for Xian Tian / Hou Tian positions | Partially — stable across 180-year Grand Cycle | All sites, especially yin zhai |
| Fu Xing Shui Fa | 輔星水法 | Hybrid San He/San Yuan | Uses the "Assistant Star" (輔星) to determine water exit quality from the Sitting direction | No — fixed formula | Quick audits, supplementary check |
| Qian Kun Guo Bao | 乾坤國寶 | San Yuan | Alternative name for Long Men Ba Ju — emphasizes the Qian/Kun trigram as the master key | Partially | Same as Long Men Ba Ju |
| Hong Fan Water | 洪範水法 | San He | Based on the "Great Flood" (Hong Fan) chapter of the Book of History; matches elements to directions | No | Traditional village planning |
| Xuan Kong Water | 玄空水法 | San Yuan (Xuan Kong) | Uses Flying Star natal chart — Water Star position determines where water features are beneficial | Yes — changes every 20-year period | Modern apartments, interior design |

🌊 The Water Mouth (水口, Shuǐ Kǒu) — The Key to Wealth Retention
The Water Mouth is the single most critical point in any water method analysis. It is the point where water exits the site — the last place you can see the water before it disappears from view. In urban settings, the Water Mouth is the point where a road curves away or where drainage leaves the property.
The classic axiom states: "Qi rides the wind and scatters; it stops at the boundary of water" (氣乘風則散，界水則止). Water defines the boundary of Qi — and the Water Mouth is where that boundary breaks, allowing Qi to escape. A tight, narrow, guarded Water Mouth retains Qi; a wide, exposed exit bleeds it away.
水口 是任何水法分析中最關鍵的一點。它是水流 離開 場地的出口——你能看到水的最後一處。在城市環境中，水口即道路轉彎處或排水出口。
經典公理：「氣乘風則散，界水則止」。水界定氣的邊界——水口即是邊界的突破口，氣由此洩。水口緊密、狹窄、有山守護則聚氣；寬闊暴露則氣散。
✅ Ideal Water Mouth Characteristics
- Narrow and guarded — flanked by buildings, hills, or vegetation
- Curved exit path — water meanders away rather than rushing straight out
- Not visible from the main door — if you can see the Water Mouth from inside, wealth "flows out the door"
- In the Mu Ku (墓庫) position — the "Tomb/Vault" sector for the Dragon's element, locking in energy
❌ Harmful Water Mouth Signs
- Wide and exposed — water rushes away with nothing to slow it
- Straight exit path — the "arrow-shooting" (直去水) formation drains wealth rapidly
- Visible from the front door — classic "seeing wealth leave" (見財化水) pattern
- Multiple exit points — Qi scatters in multiple directions simultaneously
🏢 Urban Water Mouth: Roads as Virtual Water
In modern cities, roads are considered virtual water (路即是水). Traffic flow creates directional Qi movement identical to water currents. Key urban water patterns:
- Curved road wrapping around building = "玉帶纏腰" (Jade Belt Wrapping Waist) — very auspicious
- Building on outside of curve = "反弓煞" (Reverse Bow Sha) — highly inauspicious; Qi flung away
- T-junction facing building = "路沖煞" (Road Rush Sha) — direct Qi attack
- Roundabout = circulating Qi; beneficial if building receives slowing traffic

⚙️ Integrating Water Methods with Flying Stars
The most effective modern practice combines traditional water methods with Flying Star natal chart analysis. Here's how the two systems work together:
| Layer | System | What It Determines |
|---|---|---|
| Macro Landscape | Long Men Ba Ju / San He Water | Which direction should external water flow IN from and OUT to? |
| Period Timing | Ling Shen / Zheng Shen | Which sector needs water vs mountain for the current 20-year period? |
| Interior Placement | Flying Star Water Stars (向星) | Which room or sector should have an indoor water feature (aquarium, fountain)? |
| Drainage | Water Mouth formula (Mu Ku position) | Where should drainage exit the property? |
💧 Period 9 Water Placement Summary
- Ling Shen for P9 = North → external water (pool, pond, river, road) is ideal in the North sector
- Flying Star Water Star 9 → find where the natal Water Star 9 sits in your chart; place an aquarium or fountain there for wealth activation
- Avoid large water features in the South (P9 Zheng Shen — needs mountain, not water)
- Drainage should exit through an inauspicious sector — never drain toward the main door
✦ ◆ ✦
🏊 Pool & Fountain Placement Rules
Shape Guidelines
- Curved/circular pools preferred — organic shapes embrace Qi
- Kidney-shaped curving toward house = "embracing water" (抱水) — very auspicious
- Rectangular pools with sharp corners pointing at the house create "poison arrows" (暗箭) — avoid
- Infinity-edge pools facing away from the house represent Qi flowing away — not ideal
Quality & Proportion Rules
- Moving water (fountains, waterfalls) better than stagnant ponds
- Clean, aerated water essential — stagnant/murky water breeds Sha Qi (煞氣)
- Water features should not exceed 1/3 of total land area
- Oversized pools create excess yin energy: lethargy, depression, respiratory issues

📋 Case Study: Reverse Bow Road in Suzhou
Case: Villa on Outside Curve of Major Road (反弓路案例), Suzhou
A villa was built on the outside curve of a major road — classic Reverse Bow Sha (反弓煞) . The centrifugal force of traffic (virtual water) directed Qi energy away from the property rather than embracing it.
History:
- 1st owner (2011–2016): went bankrupt
- 2nd owner (2017–2021): suffered a serious car accident
- 3rd prospective owner (2022): commissioned a water methods audit before purchase
Diagnosis: The reverse bow directed centrifugal Qi force directly at the living room. The South-facing door received road rush compounded by the curve — a double water affliction.
Remedy:
- Build a 2.5-metre stone wall with climbing plants between road and house
- Relocate the main entrance to the side of the house facing away from the curve
- Plant a dense row of bamboo as a Qi buffer between wall and house
Outcome: The 3rd owner has lived there since 2023 without incident, reporting stable career progress and good health — demonstrating that even severe water afflictions can be mitigated with proper remediation.
