After determining the location of the burial site, the next step must be to carefully assess the depth of burial. The term "shallow and deep" refers to the precise standard for burial depth.
If the depth is precisely calibrated to receive the vital energy (Shengqi), the efficacy of feng shui will naturally be achieved. Therefore, those who select sites and fix穴位 must use depth as their precise measure. 🌱
When one should bury shallow but digs too deep, the vital energy passes over the top; when one should bury deep but buries too shallow, the vital energy escapes beneath. Even if a propitious site has been chosen, the expected results will not manifest—this is precisely the reason.
In general, first observe the yin-yang nature of the incoming vein (Rushou), then examine the supporting coordination of the surrounding mountains. For example: when the incoming vein arrives with vigorous force, the acupoint form is concave, and the exit is rounded—these are all signs of vital energy floating near the surface, with the acupoint being yang in nature, suitable for shallow burial. When the incoming vein arrives with weak force, the acupoint form is convex, and the exit is sharp—these are all signs of vital energy sinking deep within, with the acupoint being yin in nature, suitable for deep burial.
Therefore it is said: When shallow and deep are properly calibrated, feng shui naturally accomplishes itself.
The rules of shallow and deep have many pathways, but the core principle is nothing more than this. The most critical point is to distinguish the yin-yang nature of the incoming vein, as well as whether the Whisker Water (Xiaxu Shui) and Boundary Conjunction Water (Jiehe Shui) are clearly defined. If one should bury deep but buries shallow, or should bury shallow but digs deep, the error of mere inches will transform an auspicious site into an inauspicious one.
The classic text states: "With an auspicious site but inauspicious burial, it is the same as abandoning the corpse"—this is precisely the meaning.
The popular practices of Zhuagua hexagram methods and the Nine Star White calculations to determine inch-level measurements are gravely erroneous.
Author's Note: It is questionable whether even Guo Pu and Yang Gong truly understood what constitutes yin-Yang of the vein and surface-interior of the vein. The Book of Burial says: "For dry and parched ground, one should bury deep; for flat and even ground, one should bury shallow." The previous section stated that concave formations indicate sinking veins, yet this section states that concave formations indicate floating veins—a self-contradiction. Which is correct? It is indeed difficult to reconcile.
The central proposition of this chapter is: The precision of burial depth directly determines the success or failure of feng shui efficacy.
The author presents a complete judgment framework:
| Judgment Dimension | Condition | Conclusion |
|---|---|---|
| Incoming vein (Rushou) | Vigorous and powerful | Floating vein→Yang acupoint→Shallow preferred |
| Acupoint form | Concave, rounded exit | Floating yang manifestation |
| Incoming vein (Rushou) | Weak and powerless | Sinking vein→Yin acupoint→Deep preferred |
| Acupoint form | Convex, sharp exit | Sinking yin manifestation |
The essential logic of this framework is: Determine the degree of human intervention (burial depth) based on the yin-yang attributes of the terrain, achieving a "unity of heaven and humanity" match.
Meanwhile, the author sternly criticizes mechanically calculating burial depth through numerological formulas such as the "Nine Star White method," viewing such approaches as a departure from natural terrain assessment.
The "Author's Note" at the end goes even further, directly questioning the internal consistency of the yin-yang vein classification itself, pointing out an apparent contradiction between the Book of Burial and this text regarding the depth judgment corresponding to "concave" formations.
From a modern perspective, the "shallow and deep" question discussed in this chapter carries certain environmental engineering significance:
Soil and Hydrological Conditions: Burial depth involves practical factors such as soil moisture, groundwater levels, ventilation, and breathability. Excessive depth may reach groundwater layers, causing prolonged soaking of the coffin; insufficient depth may be affected by surface runoff erosion or severe temperature fluctuations. The original observation that "dry heights favor deep, flat terrain favors shallow" can be understood in soil science as: the deep soil layers of dry highlands have more stable moisture, while flat areas achieve stable conditions at shallower depths.
Topography and Microclimate: Concave acupoints (such as basins and nest forms) differ significantly from convex acupoints (such as slopes and teat-shaped mounds) in terms of sunlight exposure, drainage, and wind protection. From an engineering standpoint, the original text's assertion that "concave favors shallow, convex favors deep" may have empirical foundations related to adjusting interactions between micro-topography and groundwater levels.
Critique of the "Nine Star White Method": The critique of formulaic numerology reflects the ancient people's sober recognition that empirical observation surpasses dogmatic formulas. This is highly consistent with the principle in modern scientific methodology that "theory must submit to evidence."
The Introspective Value of the Author's Note: The author's note point out the text's self-contradiction. This critical attitude that does not回避 conflicts within canonical works is extremely precious in ancient Chinese geomantic literature. It suggests to later readers that traditional theory is not a monolithic entity—the divergences between different schools precisely leave room for practical verification.
Modern application should focus on rational judgment in environmental selection, not burial customs:
Site Selection Decision Reference: Extend "shallow and deep" to embedding depth decisions for building foundations. For low-lying, damp locations, foundations should be dug deep to stable strata; for elevated, dry terrain, shallow foundations suffice to meet load-bearing requirements. This resonates with the original text's observational logic of "flat favors shallow, dry-and-parched favors deep."
Site Assessment Checklist: Transform the text's "observe the yin-yang of the incoming vein, examine the support of the four mountains" into modern site assessment dimensions—terrain trend (incoming vein), surrounding environment (four mountains), local form (acupoint shape), drainage conditions (boundary conjunction water). These four dimensions remain basic elements of site suitability assessment even today.
Hypothesis—Action—Review: When selecting among sites within a certain area, one may preset two hypotheses—"shallow suitability" and "deep suitability"—and verify them through soil exploration, groundwater level monitoring, and other data before determining the final plan. This workflow mirrors the original text's decision sequence of "first distinguish yin-yang, then determine shallow-deep."
The philosophical tension embedded in this chapter lies in the dialectical relationship between "precision" and "ambiguity" :
On one hand, the original text emphasizes that "an error of mere inches transforms good fortune into misfortune," endowing imperceptibly small spatial differences with decisive significance. On the other hand, the author's note at the end reveals the irreconcilable ambiguity within the theoretical system itself. This tension exposes a deeper question: Is traditional geomancy pursuing objective physical laws, or a subjective interpretive system?
The proposition "when shallow and deep are properly calibrated, feng shui naturally accomplishes itself," if stripped of its numerological shell, reveals its philosophical core: The degree of human intervention should be suited to natural environmental conditions. Excess and deficiency are both inauspicious. This is the concrete manifestation of the Chinese philosophy of "moderation" (Zhongyong) in spatial practice.
The author's note questioning whether "Guo Pu and Yang Gong truly understood yin-yang veins" touches another philosophical layer: the relationship between authority and truth. True knowledge should not depend on what authorities "know," but should withstand the dual scrutiny of logical consistency and practical verification. This critical spirit is precisely the internal driving force that allows traditional scholarship to renew itself.
Rushou (Incoming Vein) : The final segment of the dragon vein's approach to the acupoint—its form and momentum at the point of "entering the head"—is the critical node for judging the auspiciousness of the acupoint. This chapter uses it as the primary criterion for determining depth.
Whisker Water (Xiaxu Shui) and Boundary Conjunction Water (Jiehe Shui) : Fine water flows on both sides of the acupoint site—left is Whisker Water, right is Crab-Eye Water, jointly called "Boundary Conjunction Water." Their function is to delimit the acupoint area and distinguish vital from dead energy. This chapter emphasizes that "clear Whisker and Boundary waters" are prerequisites for depth judgment.
Nine Star White Method : A method using the nine stars—Greedy Wolf, Giant Gate, Rolling Fortune, Literary Curve, Chastity, Military Music, Broken Army, Left Aide, Right Assistant—paired with directions and water methods to calculate burial depth in inches. The original text dismisses it as "gravely erroneous," reflecting the strategic-shape school's (Luantou) critical stance against the formulaic operations of the principle school (Liqi).
Yin-Yang of the Vein / Floating-Sinking of the Vein : Refers to the surface or deep stratification of vital energy within the incoming vein. Floating vein is yang-natured, with vital energy near the surface, obtainable by shallow digging; sinking vein is yin-natured, with vital energy in the depths, requiring careful deep digging. However, as the author's note exposes, the specific identification criteria for this classification vary and even conflict across different classics.
The Book of Burial (Zang Shu, Guo Pu): Its assertion that "dry and parched ground suits deep burial, flat and even ground suits shallow burial" forms a point of comparison with this chapter; examining both texts side-by-side reveals differing standards for shallow-deep judgments.
The Classic of Cyan Bag (Qing Nang Jing): Covers fundamental principles of burial methods and the theory of vital energy aggregation and dispersal, providing broader theoretical background for understanding "proper calibration of shallow and deep."
Compendium of Geographic Knowledge for Human Conduct (Di Li Ren Zi Xu Zhi, compiled by Xu Shanji and Xu Shanshou, Ming Dynasty): Contains extensive case analyses of acupoint methods and depth operations, supplementing the brevity of this chapter's exposition.
Ode to the Snow Heart (Xue Xin Fu): Discusses essentials of mountain forms in rhymed prose; sections on concave-convex acupoint forms and vein floating-sinking are directly related to this chapter.
Landscape Ecology Perspective: Contemporary scholars have engaged in dialogues between traditional geomancy concepts such as "incoming vein" and "boundary water" and the landscape ecology model of corridor–patch–matrix, proposing that depth selection in traditional burial methods reflects ancient people's intuitive recognition of micro-topographic ecological niches.
Verification by Soil Science and Hydrogeology: Some researchers have attempted geoscientific verification of traditional "shallow-deep" rules, discovering empirical correspondences between many rules and soil moisture distribution patterns in the vadose zone. While this does not prove the validity of the numerological theories, it demonstrates that the ancients indeed accumulated valuable environmental observational knowledge.
Epistemological Reflection: The contradictions within canonical texts revealed by the author's note provide a classic case study for examining interpretive flexibility within Chinese traditional knowledge systems. Some scholars argue that geomancy classics function less as "technical manuals" than as "interpretive frameworks"—tools for flexibly assigning meaning rather than strict causal-predictive models.
