Method for Distinguishing Face from Back
背面辨別法
雖然已識枝中幹,長作京都短作縣。枝中有幹幹有枝,心裏能明口能辯。只恐尋龍到此窮,兩水夾來風蕩散。也有方州並大邑,直到水窮山絕獻。也有城隍一都會,深在山原隈僻畔。今日君尋到水窮,砂礫坦然纏護竄。右尋無穴左無形,無穴無形卻尋轉。尋轉分枝上覓穴,惟見縱橫枝葉亂。也識轉喚也識纏。也識護托也識纏。只是弧疑難捉穴,穴若假時無正案。到此之時心生疑,若遇高明能剖判。為君決破之疑心、枝幹亂時分背面。假如兩水夾龍來,便看外纏那邊回。纏山纏水回抱處,背底纏山纏水隈。
Though one already recognizes the trunk within the branches — long trunks forming capitals, short ones forming counties. Branches contain trunks and trunks contain branches; the heart can understand what the mouth can articulate. The only fear is that tracing the dragon reaches exhaustion here — two waters converge and wind scatters everything. Some prefectures and great towns extend right to where water ends and mountains vanish. Some walled cities and metropolitan centers hide deep in mountain-plain recesses. Today you trace to where the water ends — gravel and sand lie flat, with wrapping and protection fleeing. Seeking right, no acupoint; seeking left, no form. With neither acupoint nor form, you turn to search again — searching up the branch divisions for acupoints, but finding only tangled branches and leaves everywhere. You recognize turning and calling; you recognize wrapping. You recognize protective support; you recognize interception. But doubt persists and the acupoint eludes capture — when the acupoint is false, there is no correct fronting-case. At this moment, doubt fills the heart. If you meet a master of high clarity who can dissect the problem, the resolution for your doubtful heart when branches and trunks are confused is: distinguish face from back. Suppose two waters converge flanking the dragon — look which side the outer wrapping returns to. Where the wrapping-mountain and wrapping-water curve back in embrace — that is the face. Where the wrapping-mountain and wrapping-water turn away into recesses — that is the back.
The Middle Chapter's central teaching is the face-back distinction (背面辨): the most reliable method for resolving ambiguous terrain. The 'face' (面) of a dragon is the side where surrounding features curve inward protectively; the 'back' (背) is the side where they turn away. This rule applies at every scale, from individual ridges to entire mountain ranges.
Decoy Acupoints and Ghost Mountains
花穴與鬼山
總饒已能分背面,面得寬平背崖巖。假如兩水夾龍來、屈曲翻身勢大轉。一回頓伏一翻身,一田轉換一回斷。兩邊皆有山水朝,兩邊皆有水抱巖。兩邊皆有穴形真,兩邊皆有穴形真,兩邊皆有山水案。兩邊朝迎皆可觀,兩邊明堂皆入選。兩邊纏護一般來,兩手下邊皆回轉。此山背面未易分。心下狐疑又能判。不應兩邊皆立穴。大小豈容無貴賤。只緣花穴使人疑。更看護身腳各辯。莫來此處談真龍。兩水夾來龍必轉。逆轉之龍有鬼山,鬼山拖腳皆後環。識得背面更識鬼,識鬼之外更識官。
Even granting that one can distinguish face from back — the face being broad and level, the back being cliffs and crags — suppose two waters converge flanking the dragon as it bends, twists, and turns dramatically. Each pause-and-descent is followed by a flip; each turn-and-shift is followed by a severance. Both sides have mountains and water paying audience. Both sides have water embracing rock-faces. Both sides show true acupoint-forms. Both sides have mountain-and-water fronting cases. Both sides' audience-greetings are worth observing. Both sides' bright halls qualify for selection. Both sides receive identical wrapping and protection. Both lower arms turn and curve. This mountain's face and back are not easily distinguished. The heart's doubt seems unresolvable. Yet both sides cannot both establish acupoints — large and small cannot both lack differentiation of rank. It is the decoy acupoint that creates this confusion. Look further at the protective body's feet to distinguish each side. Do not come here to discuss the true dragon — when two waters converge, the dragon must turn. A counter-turning dragon has a ghost mountain — the ghost mountain's trailing feet all curve around behind. Once you recognize face and back, learn to recognize ghosts. Beyond recognizing ghosts, learn to recognize officials.
'Ghost mountain' (鬼山 guǐshān): A formation trailing behind the acupoint on the dragon's back side. When a dragon turns, the outer side of the turn produces a trailing ridge — this is the ghost. Its presence confirms which side is the true face (the inner curve) and which is the back (the outer curve with the trailing ghost).
'Official' (官 guān): A formation on the audience-mountain's back side that trails away from the acupoint. While the ghost trails behind the acupoint, the official trails behind the facing mountain. Officials should curve back toward the acupoint; if they do not, the audience-mountain is false.
'Decoy acupoints' (花穴 huāxué): False formations that mimic all the features of a true acupoint — audience mountains, bright hall, wrapping, and protection — but lack genuine qi. They are the most dangerous traps in feng shui practice because they can deceive even experienced practitioners.
Ten Mountains and Nine Waters: Ranking Noble and Base Dragons
十山九水與貴賤龍
問君疑龍何處難,兩水之中必有山。兩山之中必有水,山水相夾是機源。假如十條山同聚,必有十水歸一處。其間一水是出門,九山同來作門戶。東行看西西山好。西上看東東山妙。南山望見北上山,山奇水秀疑似間。北上看見南山水,矗矗尖奇秀且麗。君如遇見此處時,兩水夾來何處是?與君更為何分別,先分貴賤星羅列。更須參究龍短長,又看頓伏星善良。尊星不青為朝見,從龍雖來撓掉藏。貴龍重重出入賬,賤龍天帳空雄強。十山九水難同聚,貴龍居中必異常。
I ask: where is the suspicious dragon most difficult? Between two waters there must be a mountain; between two mountains there must be water. Mountains and waters flanking each other are the mechanism's source. Suppose ten mountain-ridges converge at one place — there must be ten waters gathering at one point. One of those waters is the exit-gate; nine mountains together form the gate-posts. Walking east, you look west — the western mountains are fine. Climbing west, you look east — the eastern mountains are wonderful. From the southern mountains, you see the northern highlands — mountains are strange, waters are beautiful, doubt and certainty mingle. From the northern heights, you see the southern waters — sharp peaks, elegant and lovely. When you encounter such a place, which of the two converging waters is the true one? How to distinguish further? First, rank the stars arrayed before you as noble or base. Then investigate the dragon's length. Then observe the pause-and-descent stars for their quality. The honored star does not willingly serve as an audience-peak; even though attendant dragons arrive, they conceal their oar-strokes. The noble dragon repeatedly enters and exits curtains; the base dragon has curtains that are merely imposing emptiness. When ten mountains and nine waters are hard to assess at once, the noble dragon occupying the center must be extraordinary.
This passage teaches how to evaluate a complex landscape where multiple dragon formations converge. The key principle: the noblest dragon does not display itself ostentatiously. It occupies the center, passes through multiple 'curtains' (帳, mountain-pass barriers), and does not serve as an audience-peak for others. Lesser dragons, despite their impressive appearance, are attendants rather than principals.
'Curtains' (帳 zhàng): Mountain ridges that a dragon must pass through on its course, like curtains or screens in a palace. Multiple curtain-piercings indicate a high-quality dragon — each passage strips away coarse qi and refines what remains, analogous to an emperor passing through successive gates.
The Ancients' Methods of Dragon-Tracing
古人尋龍之法
若不窮源論祖宗,也尋頓伏識真蹤。古人尋龍尋頓伏,蓋緣頓伏生尖曲。曲轉之徐必生枝,枝上必為小關局。譬如人行適千里,豈無解鞍並頓宿。頓宿之所雖未住,亦有從行並部曲。頓伏移換並退卸,卻看山面何方下。移換卻須尋回山,山回卻有迎送還。迎送相從識龍面,龍身背上是纏山。纏山轉來龍抱體,此中尋穴又何難。古人建都與建邑,先尋頓伏識龍關。升虛望楚與涉懶,此是尋頓與山面。降觀於桑與降原,此是尋伏下平田。度其夕陽挨以日,南北東西向無失。乃涉南岡景於京,此是望穴識龍形。險彼百泉觀水去,陳彼溶原觀水聚。或險南岡與太原,是尋頓伏非茍然。古人卜宅貴詳審,經旨分明與後傳。
If one cannot trace origins to discuss ancestral mountains, at least seek the pauses and descents to identify the true track. The ancients traced dragons by tracing pauses and descents — because pauses and descents produce sharp turns. At slow turns, branches necessarily emerge; on the branches, small barrier-enclosures necessarily form. It is like a person traveling a thousand li — surely there are stops for unsaddling and lodging. The lodging-place may not be the destination, but there are companions and retinue there too. Pausing, descending, shifting, exchanging, retreating, shedding — observe which direction the mountain-face descends. For shifts and exchanges, seek the returning mountain — where the mountain returns, there is welcoming and escorting. By following the welcoming and escorting, you recognize the dragon's face. On the dragon's back are the wrapping-mountains; when wrapping-mountains turn and the dragon embraces its body — finding acupoints there presents no difficulty. The ancients built capitals and towns by first tracing pauses and descents to identify the dragon's barrier. 'Ascending the height to survey Chu' and 'wading through the laziness' — these are tracing pauses and mountain-faces. 'Descending to observe the mulberry-fields' and 'descending to the plain' — these are tracing descents to level fields. 'Measuring the evening sun, aligning by the daylight' — north, south, east, and west never err. 'Ascending the southern ridge, taking the prospect of the capital' — this is surveying the acupoint and recognizing the dragon's form. 'Scaling that hundred-spring summit to observe where water goes' and 'surveying that dissolving plain to observe where water gathers.' Whether scaling the southern ridge or the Taiyuan plain — this is tracing pauses and descents, not idle work. The ancients esteemed careful deliberation in selecting sites. The Classic's principles are clear and transmitted to later generations.
The quoted phrases come from the Book of Odes (詩經), specifically from poems describing royal site-selection expeditions. Yang Yunsong interprets these ancient agricultural and political poems as encoding feng shui methodology: 'ascending heights' corresponds to tracing dragon pauses; 'descending to plains' corresponds to tracing dragon descents; 'measuring by the sun' corresponds to directional alignment.
This passage establishes the claim that feng shui site-selection is not a later invention but was practiced by the Zhou dynasty founders. By citing canonical Confucian texts (the Book of Odes), Yang Yunsong gives his technical art intellectual and moral legitimacy.
