TL;DR: Shen Zhurang (沈竹礽) was a geomancy master from Zhejiang in the Qing dynasty, regarded by Huyen Khong texts as the successor to Jiang Dahong. The set Trạch vận tân án, whose Vietnamese translation lists the author as Shen Zhurang and other authors, relates that he used the Hoán tinh khẩu quyết, that is Thế Quái, to supplement the old oral formula and worked out the group of 16 xảo số cục of one qi connected through the nine palaces. That is the claim of that line of books itself; the effectiveness of this discipline has not been independently verified.
Who Was Shen Zhureng?
Shen Zhureng was a geomancy master from Zhejiang who lived during the Qing dynasty, cited in Huyen Khong studies texts as the successor and developer of this school after Jiang Dahong of the Ming dynasty. The introduction in the Vietnamese translation of Trạch vận tân án states: from Jiang Dahong he received the foundation, then continually researched and expanded Huyen Khong studies; his two works, Thẩm thị Huyền Không học and Địa lý biện chứng quyết yếu, emerged from this, after which he gathered scholars and students to compile Trạch vận tân án[1].
That introduction should be read with caution. The cover of the Vietnamese translation gives the author as "Thẩm Trúc Nhưng and other authors", the sections of the book refer to him in the third person, and the case section includes cases dated to the Đinh Mão year (1927) and the Tân Mùi year[1]. Reference works usually give his personal name as Shen Shaoxun (沈紹勳), born in 1849, died in 1906, a native of Qiantang, Zhejiang; if so, the case section was written by later members of the school. In this article, when we say he "made public" something, it should be understood as public within the circle of contemporary and later geomancy researchers.
Why Is Shen Zhureng Said to Have Made Secret Teachings Public?
The most emphasized point about Shen Zhureng is that he revealed certain methods that earlier masters usually kept secret. The section Xảo số tam ban quái of Trạch vận tân án states: in the Tam nguyên cửu vận system, mountain-water-plain configurations comprise 180 chính cục, 180 đảo cục, and 432 biến cục, totaling 1944 cục; the group of clever numbers "one qi connected through all nine palaces" includes only 16 cục, roughly 1/122, and is therefore considered wondrous and rare[1]. The translation says this mystery was discovered by Master Shen of Zhejiang and made public together with the lay scholar Thẩm Điệt Dân, "opening a secret handed down for a thousand years" to the world[1].
This statement must be read in proper measure. It is the self-account of that very lineage of texts, the view of the school, not an independently verified fact. The "publication" here occurred within the lineage, through printed books and students, not a widespread dissemination with its own historical record. In other words, we can affirm that the book says so, but cannot affirm it as verified historical truth.
How Does the Huyen Khong Studies That Shen Zhureng Pursued Operate?
The overview at the start of Trạch vận tân án says that Huyen Khong studies takes four aspects as its basis, Form, Principle, Qi and Number, and that its most prominent feature is using the "moving mouth" (active opening) in the facing direction as the basis for judgment; the book itself claims its judgments always match the course of events[1]. The book also recounts the lineage: in the Song dynasty, Wu Jingluan added theory and practice; in the Ming dynasty, Jiang Dahong with Địa lý biện chính sơ clarified the true and false aspects of geomancy; by the Qing dynasty, Shen Zhureng continued to develop on that foundation[1].
In short, the Huyen Khong studies he followed is the Tam Nguyên school, using period as the time axis, sitting-facing and moving mouth as the space axis, then assigning numbers to positions to judge fortune and misfortune. A core point of the book is the principle that the dragon spirit of the mountain must sit on high ground and the dragon spirit of the water must meet water: the prosperous stars of the mountain chart need mountain, the prosperous stars of the facing chart need water, and declining or dead qi the reverse; doing the opposite violates "thướng sơn hạ thủy", which according to the book brings "decline of both people and wealth"[1].
Nine Stars on the Palm and the Method of Placing Stars
Trạch vận tân án states: to understand Huyen Khong studies, the prerequisite is to be proficient in the nine stars on the palm, also called Chưởng Ác Cửu Tinh[1]. This is a method of memorizing the positions of the nine palaces on the hand to quickly place stars during analysis. The placing of stars, flying stars, and determining palaces are conventions of the book, not verifiable calculation results like calendrical science, so they belong to the school's interpretive layer.
How Did Shen Zhureng Make Public the Hoán Tinh Formula?
The most specific point is in the section of Trạch vận tân án that explains Thế Quái and its origin. It relates that he befriended the son of Chương Trọng Sơn (章仲山), a noted master of the Daoguang era, borrowed the field-survey records that Zhang had left only to his descendants, and from them grasped many things earlier masters had not spelled out[1]. The book cites the ancient formula from Thanh nang áo ngữ: "Khôn Nhâm Ất, Cự Môn tòng đầu xuất. Cấn Bính Tân, vị vị thị Phá Quân. Tốn Thìn Hợi, tận thị Vũ Khúc vị. Giáp Quý Thân, Tham Lang nhất lộ hành," then comments that this formula has dominated for a thousand years but its correctness remains undetermined, while hundreds of works claiming true transmission have failed to produce results when applied[1].
According to the book, Shen Zhureng investigated deeply, believed the cryptic language was like a divine dragon hiding half its body in clouds, preventing people from seeing clearly, so he used the Hoán tinh oral formula to supplement it, called Thế Quái in Thẩm thị Huyền Không học[1]. The book records the supplementary formula, including lines such as "Tý Quý tịnh Giáp Thân, Tham Lang nhất lộ hành," "Nhâm Mão Ất Mùi Khôn, ngũ vị vi Cự Môn," and a conclusion emphasizing "Hung cát tùy thời chuyển, Tham Phụ bất đồng luận"[1].
The interpretation here is that instead of rigidly adhering to the old formula, he added a conversion layer to handle cases the old formula could not explain. Notably, the book itself admits that the foundational formula "still cannot be concluded as correct or incorrect"[1]. This is a very important self-admission, showing that even within the lineage, the method's uncertainty was recognized, not a closed system already proven.
What Is the Clever Number "One Qi Through Nine Palaces"?
According to Trạch vận tân án, the special clever number group comprises 16 cục; among them the triples 1-4-7, 2-5-8, 3-6-9 each lie in one palace, likened to a string of linked pearls, whether forward or reverse always three apart, completely natural, without force[1].
This is a mathematical-aesthetic interpretation: the group of three numbers three units apart gives a sense of order, and that order is assigned auspicious meaning. It must be stated clearly: no independent research proves that houses following such number groups are more prosperous. Its value lies in the internal consistency of the system, not in verified efficacy.
Địa lý biện chính and the Intellectual Current Before Shen Zhureng
To understand Shen Zhureng's position, one must look at his predecessor. Jiang Dahong, in the preface to Địa lý biện chính, recounts that he lost his mother young, lost his father as an adult, received form-school books from his grandfather An Khê, later realized the common learning was incorrect, and found the transmission of Vo Cuc Tu[3]. He says he studied ten years to receive the transmission, another ten to grasp the meaning, and another ten to master the transformations, by which time he was old[3].
Jiang Dahong also wrote clearly that geomancy has books beginning with Hoàng Thạch, flourishing with Dương công, and the most bewildering and difficult to resolve is Ngọc Xích, so he gathered the books into one compilation to remedy this[3]. He also said he "had formulas but no books," because this matter values heart-to-heart transmission, cannot be fully expressed in words, and a house full of old books is half forged[3]. Thus Địa lý biện chính emerged as a text of rectification, criticizing errors and distinguishing right from wrong.
This is a self-account in the original text, proving what the text says, not proving those events occurred exactly so. However, it shows an important feature of this lineage: internal self-criticism and awareness of the problem of forged books existed well before Shen Zhureng.
How Do the Books Differ?
| Content | Trạch vận tân án | Địa lý biện chính (Jiang Dahong) | Nguyên Không pháp giám |
|---|---|---|---|
| Role of Shen Zhureng | Named as the discoverer of the clever numbers and the Hoán tinh formula | Not mentioned, as it predates him | Not mentioned; the preface is dated 1839 |
| Mode of transmission | Written as a book, with student assistance | Had formulas but no books, advocated heart transmission | Excerpted essentials for easier understanding |
| Attitude to old books | Supplemented old formula, admitted old formula unclear | Criticized forged books, said half are fake | Complained Jiang's rectification book was still vague |
| Intended readers | Huyen Khong students, lineage disciples | Those with foundation, not indiscriminately taught | Filial descendants wanting to bury relatives |
The table shows an interesting tension. Jiang Dahong said he "had formulas but no books," while the books of the Shen lineage were later written down and published. Between those two points, the preface to Nguyên Không pháp giám by Tăng Hoài Ngọc, dated the 19th year of the Daoguang reign, 1839, had already complained that reading Jiang's Biện chính was vague and obscure, unsatisfying, fearing that wicked people might exaggerate it to deceive others for profit, so he excerpted the essentials to offer to the world[2]. Thus even those within the lineage recognized that dissemination could be exploited, an internal counterargument worth noting.
Specific Examples in Trạch vận tân án
Trạch vận tân án is not only theory. The case section records the case of the Lợi Xương Thái Company on Tân Vĩnh An Road, Shanghai: the house was built in period 3, sitting Nhâm facing Bính with Tý Ngọ four degrees, modern style with three floors and nine rooms, door at the Tốn palace, stairs and entrance also in Tốn[1]. The book recounts that the company faced many disputes, difficult business, and great losses; on inspecting the compass, the main door and elevator both fell in the Tốn palace, where the Vũ Khúc Kim star is the ruling star, so it could not absorb life-prosperity qi[1].
In the winter of the Canh Ngọ year, the company changed the main door to the Khôn direction and moved the elevator to the Càn direction, completing repairs by year's end at a cost over ten thousand dollars; the director's office and accounting office, located in the Cấn direction, are said by the book to have absorbed the Tứ Lục prosperous qi of Khôn; at Cấn, the Lục Bạch host star met Nhất Bạch becoming Thủy Tiên Thiên, and the facing Cửu Tứ combined to create a life-entering configuration for the sitting mountain[1].
This is an illustrative example in the book's narrative style. It should be read as a case analysis, not a controlled experiment. The book provides no revenue figures before and after, does not exclude other factors like market or management, so it cannot be used to conclude the efficacy of changing door direction. Its value is showing how the method is applied concretely, not proving the method correct.
Why Distinguish Factual and Interpretive Layers?
Throughout the story of Shen Zhureng, there are two very different types of propositions. The first concerns texts: which book says what, on which page, who wrote the preface, in which reign year. This is verifiable by opening the book and comparing. The second concerns efficacy: arranged thus brings wealth, violated thus brings decline. This belongs to the belief of the discipline and has not been independently verified.
When the book says violating thượng sơn hạ thủy brings decline of both people and wealth, that is a rule of the system, presented as a rule, not as a measurement result. This distinction is not to deny the cultural value of the lineage, but to let readers know what they are reading: a rich interpretive tradition with clear textual history, but not an experimental science.
Summary of Shen Zhureng's Portrait
Shen Zhureng is regarded in Huyen Khong studies texts as the central figure of the Tam Nguyên school in the Qing dynasty, associated with turning a lineage that advocated oral transmission into books that can be studied and taught. His most mentioned contributions are the Hoán tinh oral formula supplementing the ancient formula, and the group of 16 clever numbers one qi through nine palaces, described as about 1/122 of the total 1944 cục[1]. Accompanying this is Trạch vận tân án, gathering theory, formulas, and practical case analyses.
The interpretation of this lineage is that he "revealed a thousand-year secret" to the world[1]. A more neutral interpretation is that he systematized and published a method previously transmitted secretly, and that publication itself created a new textual tradition, open to criticism, revision, and expansion. For today's reader, the greatest value of this heritage perhaps lies in showing that ancients tried to model the relationship between living space and fortune with a consistent symbolic system, not in promises of results.
