Xuan Kong Six Methods (玄空六法) is a highly specialized San Yuan system utilizing Er Yuan Ba Yun (Two Cycles, Eight Periods). Attributed to the scholarly lineage of Tan Yang Wu (谈养吾, 1888–1969), it claims to restore the original intent of the ancient San Yuan classics — particularly the Qing Nang Jing (青囊经) and the Tian Yu Jing (天玉经) — which Liu Fa practitioners argue were distorted by later Flying Star interpretations.
Unlike standard Xuan Kong Flying Stars (飞星派), which focuses primarily on charting star positions within a nine-palace grid, Liu Fa demands an integrated landscape reading of six interconnected factors. The system treats the compass chart not as the primary tool, but as a secondary confirmation of what the landscape itself reveals. For Liu Fa practitioners, the terrain speaks first — the chart merely translates.

🔑 The Six Methods Explained (六法详解)
Each of the six methods corresponds to a fundamental principle encoded in the classical San Yuan texts. Together, they form a complete diagnostic framework — no single method is sufficient alone.
| # | Method | Chinese | Pinyin | Core Function | Classical Source |
|---|
| 1 | Mysterious Void | 玄空 | Xuán Kōng | The overarching principle of time-space interaction — "Xuan" (玄) means the mystery of time; "Kong" (空) means the void of space. Together they describe how Qi quality shifts with each period in an infinite cycle. | Qing Nang Jing (青囊经) |
| 2 | Male-Female Pairing | 雌雄 | Cí Xióng | The Yin-Yang polarity of landscape features. Mountains are Yang (雄, male); water is Yin (雌, female). A valid site requires both — the mountain embraces, the water gathers. Neither alone can produce Qi. | Qing Nang Jing: "The key of Xuan Kong lies in the copulation of Ci Xiong" |
| 3 | Golden Dragon | 金龙 | Jīn Lóng | The "zero spirit" (零神) dragon that governs wealth activation for each period. The Jin Long identifies which sector must have water (Ling Shen) and which must have mountain (Zheng Shen) — the pivotal wealth/health polarity. | Tian Yu Jing (天玉经): "Jin Long — when one hexagram rules, it governs the whole" |
| 4 | Approaching Stars | 挨星 | Āi Xīng | The method of "walking" the stars through the Luo Shu sequence. Unlike Flying Stars' mechanical forward/reverse flying, Liu Fa's Ai Xing traces the Qi transformation across the landscape by connecting the Dragon, Water, and Facing into a unified star path. | Tian Yu Jing: "The secret of Ai Xing is not to be transmitted lightly" |
| 5 | Castle Gate | 城门 | Chéng Mén | The specific sector ±45° from the Facing direction where an opening, road, or water body can dramatically enhance the site's Qi intake. The Castle Gate acts as a secondary "mouth" for the property — as important as the main door in some configurations. | Tian Yu Jing: "To determine how great the fortune, look to the Castle Gate lock" |
| 6 | Grand Duke | 太岁 | Tài Suì | The annual Qi influence based on the year's Earthly Branch. Tai Sui determines which sectors are activated or suppressed each year, adding a temporal overlay to the spatial analysis. Disturbing the Tai Sui sector (construction, drilling) invites misfortune. | Annual almanac tradition; integrated into Liu Fa as the 6th method for timing renovations and activations |
The Interlocking Logic
The six methods are not independent checklists — they form a causal chain . Xuan Kong (time-space) sets the context. Ci Xiong (male-female) identifies the Yin-Yang balance of the terrain. Jin Long (Golden Dragon) determines the period-specific wealth axis. Ai Xing (stars) maps the Qi flow. Cheng Men (Castle Gate) optimizes the Qi entry. Tai Sui (Grand Duke) governs the timing of activation. A site that passes all six checks is considered "六法皆合" (liù fǎ jiē hé — all six methods in harmony) — the highest grade in the system.

📖 Theoretical Foundation: Liu Fa's Reading of the Classics
Liu Fa's theoretical backbone rests on a specific interpretation of three ancient texts that Tan Yang Wu argued had been misread by the Shen Shi (沈氏) Flying Star lineage:
1. Qing Nang Jing (青囊经 — Green Satchel Classic)
Liu Fa reads the Qing Nang Jing's description of "Xuan Kong" not as a mathematical charting system but as a philosophical description of time-space polarity . The text's famous line — "Look up to observe the patterns of heaven; look down to examine the configurations of earth" (仰以观于天文，俯以察于地理) — is interpreted literally: the practitioner must first read the sky (time/period) and then read the land (terrain), not merely calculate a nine-palace chart.
2. Tian Yu Jing (天玉经 — Heavenly Jade Classic)
The Tian Yu Jing's verse on "Jiang" (江, rivers) is read by Liu Fa as encoding the Er Yuan Ba Yun (Two Cycles, Eight Periods) system rather than the San Yuan Jiu Yun (Three Cycles, Nine Periods) used by Flying Stars. This is the single most controversial divergence: Liu Fa uses a 180-year mega-cycle divided into two 90-year cycles of four periods each, while Flying Stars uses a 180-year cycle divided into three 60-year cycles of three periods each.
3. Du Tian Bao Zhao Jing (都天宝照经 — All-Heaven Treasure Mirror Classic)
Liu Fa interprets this text's water method passages as confirming that the landscape must match the chart — if the physical terrain contradicts the star arrangement, the terrain governs. This "land-first" hierarchy is the philosophical core that separates Liu Fa from chart-centric Flying Stars.
六法的理論骨架建立在對三部古典文獻的特定詮釋之上，談養吾認為沈氏飛星派對這些文獻存在誤讀：
一、青囊經
六法將《青囊經》描述的「玄空」解讀為 時空極性 的哲學描述，而非數學排盤系統。經文名句「仰以觀於天文，俯以察於地理」被照字面理解：修習者必須先讀天象（時運），再讀地形（地勢），而非僅計算九宮圖。
二、天玉經
《天玉經》中關於「江」的經文，六法解讀為編碼了 二元八運 系統，而非飛星派所用的三元九運。這是最根本的分歧：六法使用180年大循環分為兩個90年小循環、每循環四運；飛星派則用180年分為三個60年小循環、每循環三運。
三、都天寶照經
六法將此經的水法章節解讀為： 地景必須與星圖吻合 ——若實際地形與星位排列矛盾，以地形為準。這種「地形優先」的層級觀是六法區別於以星圖為中心的飛星派的哲學核心。
☯️ Tan Yangwu's Tai Ji Principle (太极旋转)
Tan Yangwu (谈养吾, Tán Yǎngwú, 1888–1969) was a scholar from Jiangsu who synthesized Liu Fa from multiple lineages. His most distinctive contribution is the Tai Ji Coiling (太极旋转, Tài Jí Xuán Zhuǎn) concept, published in Xuan Kong Liu Fa Ben Yi (玄空六法本义, "Original Meaning of Xuan Kong Six Methods").
Tan argued that every Xuan Kong calculation ultimately maps onto a Tai Ji diagram where yin and yang create spiral movement :
- The Dragon spirals toward the Xue (穴) along the mountain ridge
- Qi spirals through the Facing into the building's interior
- Water spirals around the Bright Hall (明堂, Míng Táng) and exits at the Water Mouth (水口)
This differs fundamentally from standard Flying Star practice, which treats the Nine Palace grid as a static matrix of star positions. In Liu Fa, the grid is a frozen snapshot of a dynamic spiral process — restoring the original San Yuan insight encoded in the Qing Nang Jing .

⚖️ Liu Fa vs Standard Flying Stars — Relationship to San Yuan
Two Branches of One Tree
Both Liu Fa and Flying Stars (飞星派, Fēi Xīng Pài) belong to the San Yuan (三元) tradition, yet they diverge significantly in method and emphasis. Understanding the differences — and the overlaps — is essential for any serious student of Xuan Kong.
| Aspect | Flying Stars (飞星派) | Liu Fa (六法) |
|---|
| Time System | San Yuan Jiu Yun (三元九运) — 3 cycles × 3 periods × 20 years = 180 years | Er Yuan Ba Yun (二元八运) — 2 cycles × 4 periods × ~22.5 years = 180 years |
| Primary Tool | Star charts (盘) calculated for each period with forward/reverse flying | Six-factor integrated landscape reading; chart as secondary confirmation |
| Star Calculation | Mechanical forward (顺飞) or reverse (逆飞) flying through nine palaces | Ai Xing (挨星) — stars "approach" based on Dragon–Facing–Water alignment |
| Emphasis | Interior room-by-room star analysis; remedies for each palace | Macro-landscape Dragon–Water matching; Yuan purity (元纯清) |
| Yuan Purity | Not required — any facing can be used with any dragon | Absolute requirement — Dragon, Facing, and Water must share the same Yuan (Tian/Di/Ren) |
| Remedies | Interior placement of water features, metal objects, plants by palace | Site selection and Facing adjustment; Castle Gate activation |
| Best Application | Urban apartments, existing buildings where landscape cannot be altered | New construction, rural sites, ancestral graves, large-scale site selection |
| Key Text | Shen Shi Xuan Kong Xue (沈氏玄空学) by Shen Zhuren | Xuan Kong Liu Fa Ben Yi (玄空六法本义) by Tan Yangwu |
| Lineage Founder | Shen Zhuren (沈竹礽, 1849–1906) | Tan Yangwu (谈养吾, 1888–1969) |
📌 Where They Overlap
Despite the differences, Liu Fa and Flying Stars share: (1) the Luo Shu (洛书) as the fundamental mathematical framework; (2) the concept of Ling Shen (零神) and Zheng Shen (正神) for determining water/mountain placement; (3) the 24 Mountains compass as the spatial measurement tool; and (4) the principle that the current period determines which stars are timely (当令) or untimely (失令). A practitioner trained in one system can learn the other relatively quickly — the divergence is in interpretation , not in the underlying cosmological model.
✦ ◆ ✦
🏔️ The Six Landscape Methods (六法地景详解)
Unlike Flying Stars' primarily arithmetic approach, Liu Fa demands physical observation of six interconnected landscape factors. Each factor must be assessed in the field before any chart is drawn:
| # | Factor | Chinese | Pinyin | What to Observe | Liu Fa Requirement |
|---|
| 1 | Dragon | 龙 | Lóng | The incoming mountain range — direction, undulation, and vitality of the ridge | Must be classified as Tian Yuan (天元), Di Yuan (地元), or Ren Yuan (人元). Must be pure (纯清) within one Yuan category. |
| 2 | Lair | 穴 | Xué | The precise point where Qi pools — terrain shape at the building site | Confirmed by terrain bulging (突起), depressions (窝), and vegetation patterns. Must sit within the Dragon's Yuan. |
| 3 | Sand | 砂 | Shā | Surrounding hills and structures protecting the site | Green Dragon Sand (青龙砂) on left, White Tiger Sand (白虎砂) on right, Table Mountain (案山) in front — must embrace without oppressing. |
| 4 | Water | 水 | Shuǐ | All water features and roads — approach direction, gathering, and exit | Must exit through the Mu Ku (墓库) position. Water mouth (水口) should be narrow and guarded. Water Yuan must match Dragon Yuan. |
| 5 | Facing | 向 | Xiàng | The orientation of the building or tomb entrance | Must harmonize with Dragon and Water simultaneously — all three must share the same Yuan (天元/地元/人元). |
| 6 | Energy | 气 | Qì | The time-quality governed by the current period | Ling Shen (零神) sectors need water; Zheng Shen (正神) sectors need mountains. Governed by the Jin Long (Golden Dragon) calculation. |

🏯 Cheng Men (Castle Gate) Method in Detail (城门诀详解)
The Castle Gate (城门, Chéng Mén) is the most practically applicable of the six methods — it can be assessed and activated even in urban apartments. A "Castle Gate" is any opening, road, or water body that falls within the sector ±45° adjacent to the Facing direction . When a timely Castle Gate is activated by real environmental Qi (traffic, water flow, open terrain), it functions as a powerful secondary wealth mouth.
The Tian Yu Jing states: "To determine how great the fortune, look to the Castle Gate lock" (要知吉凶大小，城门一诀最为良). This verse establishes the Castle Gate as the decisive factor when all other conditions are roughly equal.
城門是六法中 最具實用性 的方法——即便在城市公寓中也可評估和啟動。「城門」指任何落在 向方±45°相鄰扇區 內的開口、道路或水體。當合時的城門被實際環境氣場（車流、水流、開闊地形）啟動時，它成為強力的次要財氣口。
《天玉經》云： 「要知吉凶大小，城門一訣最為良。」 此句確立城門為其他條件大致相當時的決定性因素。
🔒 The Eight Castle Gate Configurations
For each of the eight primary Facing directions, the Castle Gate sectors are the two adjacent sectors (one on each side). A Castle Gate is "open" when that sector has real environmental activation — a road, river, park, or open plaza. It is "locked" when that sector is blocked by a wall, building, or high ground.
| Facing Direction | Left Castle Gate | Right Castle Gate | Best Gate for Period 9 | Activation Example |
|---|
| South (午 Wǔ) | SE — 巽 Xùn | SW — 坤 Kūn | SW (坤) — Earth produces the 9-Fire period star | Open park or busy road to the SW of a south-facing building |
| North (子 Zǐ) | NW — 乾 Qián | NE — 艮 Gèn | NE (艮) — 8-Earth star still has residual power in early Period 9 | Low terrain, creek, or traffic circle to the NE |
| East (卯 Mǎo) | NE — 艮 Gèn | SE — 巽 Xùn | SE (巽) — Wood feeds Fire; supports Period 9 energy | River or main road curving past the SE sector |
| West (酉 Yǒu) | SW — 坤 Kūn | NW — 乾 Qián | SW (坤) — Earth produces Fire; strong Period 9 support | Open plaza or parking area to the SW |
| SE (巽 Xùn) | South — 离 Lí | East — 震 Zhèn | South (离) — Direct Period 9 star sector | Water feature, road, or balcony view to the South |
| NW (乾 Qián) | West — 兑 Duì | North — 坎 Kǎn | North (坎) — Ling Shen (零神) water position for Period 9 | Pond, fountain, or busy road to the North |
| NE (艮 Gèn) | North — 坎 Kǎn | East — 震 Zhèn | East (震) — Wood generates Fire; future Period growth | Open field, playground, or traffic flow to the East |
| SW (坤 Kūn) | South — 离 Lí | West — 兑 Duì | South (离) — Fire-to-Fire; maximum Period 9 resonance | Bright open view, road, or water body to the South |
🔍 Castle Gate Activation Checklist
- Identify the Facing — take a precise Luopan reading of the building's front orientation
- Locate the two adjacent sectors — these are your potential Castle Gates
- Check for environmental activation — is there a road, water, open terrain, or gap between buildings in either sector?
- Assess timeliness — does the activated sector's star support the current period? (For Period 9: Fire and Earth stars are timely)
- Confirm Qi flow direction — the Castle Gate must have Qi actively flowing toward the property, not away from it

🔧 Practical Application: Property Audit Using Liu Fa (六法审宅步骤)
The following step-by-step process describes how a Liu Fa practitioner conducts a full property assessment. This sequence is non-negotiable — skipping steps produces unreliable results.
| Step | Action | Tools Required | What You're Looking For |
|---|
| 1 | Identify the Dragon (龙) — trace the incoming mountain or ridge to determine the Dragon's approach direction | Luopan (24 Mountains ring); topographic map | Dragon's Yuan category: Tian Yuan (天元), Di Yuan (地元), or Ren Yuan (人元) |
| 2 | Locate the Lair (穴) — find the precise point where Qi gathers based on terrain features | Visual inspection; vegetation and soil analysis | Bulging, depression, or sheltered hollow that collects rather than disperses Qi |
| 3 | Assess the Sand (砂) — catalog all surrounding hills, buildings, and structures | Luopan; binoculars for distant features | Green Dragon (left), White Tiger (right), Table Mountain (front), Backing Mountain (rear) — all present and balanced |
| 4 | Map the Water (水) — trace all water features, roads, and elevation drops | Luopan (Tian Pan for water exit); property plumbing plan | Water approach direction, gathering pattern, exit direction. Water Yuan must match Dragon Yuan. |
| 5 | Determine the Facing (向) — take a precise compass reading of the building's orientation | Luopan at the center of the building or main entrance | Facing must share the same Yuan as Dragon and Water — Yuan purity (元纯清) check |
| 6 | Calculate the Energy (气) — determine the current period's Ling Shen and Zheng Shen | Period calculation table; Jin Long formula | Water features must be in the Ling Shen sector; mountains/buildings must be in the Zheng Shen sector |
| 7 | Check the Castle Gate (城门) — identify if a timely Castle Gate is open and activated | Luopan; field observation of roads, gaps, water | At least one adjacent sector to the Facing must be open with active Qi flow |
| 8 | Assess Tai Sui (太岁) — check annual influences and construction taboos | Chinese almanac; annual Flying Star chart | No construction or ground-breaking in the Tai Sui sector of the current year |
The Yuan Purity Gate (元纯清 — Pass/Fail)
Steps 1, 4, and 5 converge at the Yuan Purity check — the single most important diagnostic in all of Liu Fa. The 24 Mountains are divided into three Yuan categories:
- Tian Yuan (天元): 子 Zǐ, 午 Wǔ, 卯 Mǎo, 酉 Yǒu, 乾 Qián, 坤 Kūn, 艮 Gèn, 巽 Xùn (the 4 cardinal branches + 4 trigrams)
- Di Yuan (地元): 甲 Jiǎ, 庚 Gēng, 丙 Bǐng, 壬 Rén, 辰 Chén, 戌 Xū, 丑 Chǒu, 未 Wèi (4 Yang stems + 4 Earth branches)
- Ren Yuan (人元): 乙 Yǐ, 辛 Xīn, 丁 Dīng, 癸 Guǐ, 寅 Yín, 申 Shēn, 巳 Sì, 亥 Hài (4 Yin stems + 4 transition branches)
If the Dragon enters from a Tian Yuan direction, the Facing must be a Tian Yuan direction, and the Water exit must be through a Tian Yuan mountain. Any cross-Yuan mixing is a fundamental violation — regardless of how favorable the star chart may appear.

Key Passage from the Tian Yu Jing
"The Eastern Trigrams and the Western Trigrams — if you can recognize them, you would laugh. Only the one who understands the Xuan Kong method can determine the five elements of the Dragon."
Liu Fa interprets "Eastern and Western Trigrams" as the Er Yuan split: the "Eastern" cycle (ascending) and the "Western" cycle (descending), forming the two 90-year periods. Flying Stars interprets the same passage differently, reading it as the forward/reverse flying direction of stars.
天玉經關鍵段落

六法將「東卦西卦」解讀為二元分割：東方循環（上升）與西方循環（下降），構成兩個九十年運程。飛星派則對同一段落做出不同解讀，視之為星飛順逆的方向指引。

📋 Case Study: Ancestral Hall in Fujian (福建祠堂)
A Tan Yangwu lineage practitioner was consulted for the renovation of a Chen-clan ancestral hall (陈氏祠堂) in rural Fujian, originally built during the Qing dynasty.
- Dragon: Di Yuan Long (地元龙) entering from the Northwest (乾, Qián)
- Facing: Zi (子, due North) — a Tian Yuan direction → Yuan impurity (元不纯)
- Water exit: Northeast (丑, Chǒu)
Diagnosis: The Dragon (Di Yuan) and Facing (Tian Yuan) were in different Yuan categories — a fundamental Liu Fa violation producing stagnation in the clan's fortunes.
Remedy: The practitioner recommended rotating the main door axis 7.5° to align with Gui (癸), which falls in the Di Yuan sector of the North, restoring Yuan purity (元纯清).
Outcome (post-2008): Three family members passed civil service exams within four years. A real estate investment returned 400% gains.
🔑 Practitioner Takeaway
Yuan purity (元纯清) is the non-negotiable foundation of Liu Fa. Before examining stars or periods, always verify that the Dragon, Facing, and Water all belong to the same Yuan category — Tian Yuan (天元), Di Yuan (地元), or Ren Yuan (人元). A 7.5° door rotation — invisible to the untrained eye — can transform a site's fortune.

📋 Case Study: Factory in Dongguan (东莞厂房)
A garment factory built in 2003 (Period 7) experienced declining orders after 2004, following the transition to Period 8. A Liu Fa audit revealed a compounded Yuan violation:
- Dragon: Ren Yuan Long (人元龙) entering from the East
- Facing: Mao (卯, due East) — Tian Yuan, mismatched with the Dragon
- Water: A drainage channel exiting through the South — which was the Zheng Shen (正神) sector for Period 8, requiring mountain energy, not water
Diagnosis: Dragon and Facing Yuan categories clashed (Ren Yuan vs. Tian Yuan). Additionally, water exited through the Zheng Shen position — the opposite of what Liu Fa prescribes. Double violation stacked against the site's fortune.
Remedy: Unable to change the building orientation, the practitioner installed a large stone landscape feature (artificial mountain) in the Southern sector to provide Zheng Shen support. The drainage was also redirected to exit through the Southwest — the Ling Shen (零神) position for Period 8, where water should flow freely.
Outcome: By 2006 the factory secured contracts with two European retailers. Revenue tripled by 2009. The Period 8 Qi was properly harnessed via environmental correction rather than demolition.
🔑 Practitioner Takeaway
When full re-orientation is impossible, Liu Fa allows environmental substitution : artificial mountains stand in for Zheng Shen, redirected drainage corrects Ling Shen. Form supports what direction cannot. Always check the current period's Ling Shen and Zheng Shen sectors first — getting these two right frequently resolves 70% of a site's energetic problems.
✦ ◆ ✦
📋 Case Study: Hong Kong Residential Flat (香港住宅)
A Period 8 apartment in Kowloon Tong with a Facing direction of Bing (丙, South-Southwest). The building's Dragon energy entered from the high-rise cluster to the North. The Liu Fa assessment was straightforward once both Ling Shen and Zheng Shen were mapped:
- Ling Shen (零神) for Period 8: Northeast — should have water or open void ✓ (apartment overlooked a public park)
- Zheng Shen (正神) for Period 8: Southwest — should have mountain or solid mass ✓ (tall residential cluster)
Analysis: Both Ling Shen and Zheng Shen conditions were naturally satisfied by the surrounding urban landscape. The Dragon (North high-rise cluster) entered cleanly into the Facing direction. Yuan purity was maintained — the Dragon and Facing both fell within the Tian Yuan category of the North-South axis.
Outcome: The owner purchased the flat in 2009 at HK$6.2 million. By 2018 the valuation exceeded HK$18 million. Career promotions came in 2011, 2014, and 2017 — a near-textbook demonstration of Liu Fa's Period-cycle timing aligning with personal advancement.
🔑 Practitioner Takeaway
Urban environments can satisfy Liu Fa requirements as effectively as natural landforms. The high-rise cluster acts as the Zheng Shen mountain; the park acts as the Ling Shen water. When scouting modern properties, scan for these two environmental signatures before examining star charts — a site that naturally fulfills Ling Shen / Zheng Shen requirements will prosper through multiple period transitions with minimal intervention.
