►About our partner
Chengdu Shui Jing Zhu Information Technology Co., Ltd. is our business partner, providing feature-rich, user-friendly, and affordable GIS products. Their product, WeMap, offers extensive GIS information and supports export to various common document formats such as CAD. Users can access an all-in-one software platform to obtain 3D topographic maps of mainland China, Hong Kong, Macau, and other regions, as well as 3D building contour models for major cities and various GIS data, making it highly convenient for research or modeling.
Simulation software like Wireless Insite often requires the accurate reconstruction of environmental features such as terrain and buildings when modeling outdoor scenarios. Insufficient scene fidelity or distortion leads to inaccurate simulation outputs. Manually drawing complex terrain and numerous buildings is impractical, while commissioning third-party measurements or consulting services to obtain databases can yield highly detailed scene models. However, this approach is not only very expensive but also often provides a level of detail that exceeds the requirements of the simulation, frequently causing complications in modeling due to excessive precision.
Moreover, users may only need 3D scene models for their projects—whether for communication or transportation planning, or other related needs—and may not have a background in CAD, Civil Engineering or GIS. Thus, it is often challenging for them to invest significant time in learning CAD or GIS-related knowledge. In this context, WeMap provides an ideal solution: it is easy to operate, affordable, and rich in database content, enabling users to quickly learn the software and obtain the required 3D scene models without spending excessive time and costs. This allows users to efficiently build the necessary scenes or obtain documents and information needed for research, helping them focus on the core issues their projects aim to solve.
Our company collaborates with Chengdu Shui Jing Zhu Information Technology Co., Ltd. to distribute the GIS product WeMap in the Taiwan local and overseas markets, providing high-quality, cost-effective GIS software products to users in Taiwan and abroad.

Based on our experience with these 100+ industries and users, a significant portion are unable to use or are even unaware of well-known domestic and international GIS software, as these software have high technical barriers from installation to use, and most of their overly specialized advanced features are unnecessary for general use. Therefore, software that provides rich GIS data and possesses GIS functions like data overlay and matching, coordinate projection transformation, map annotation and drawing management, and cloud/mobile data synchronization can solve most of their problems. Shui Jing Zhu's WeMap is precisely such a lightweight GIS product integrating map downloading and GIS functions. We strive to make WeMap simple and easy to use, accessible for ordinary users. On the foundation of meeting basic GIS application functions, we then provide corresponding industry-specific functional plugins, aiming to make it the outstanding product of the Chinese Geographic Information (GIS) industry!
►Why Are We Called Shui Jing Zhu?
Long, long ago, there was a book called Shui Jing (《水经》, The Water Classic), which recorded only 137 rivers.
About 200 years later, a geographer named Li Daoyuan found Shui Jing to be "rudimentary in connecting the essentials, and lacking comprehensive coverage" ("虽粗缀津绪，又阙旁通"). Furthermore, feeling he had "much leisure time, idly passing the years" ("窃以多暇，空倾岁月"), he decided to "narrate Shui Jing, expanding upon the former text" ("辄述《水经》，布广前文") and annotated the book, resulting in the work named Shui Jing Zhu (《水经注》, Commentary on the Water Classic). If Li Daoyuan is considered the pioneering founder of the geographic information industry, then Shui Jing Zhu is akin to the bible of this industry.
Looking at Shui Jing Zhu today, some of the ancient sites and landforms recorded can still be verified, while others have vanished after more than 1400 years of change and historical upheaval. Despite this, Shui Jing Zhu still holds very high value for geographical research and literature.
If, throughout history, people of vision had continuously carried forward Li Daoyuan's work, revising Shui Jing Zhu like compiling historical records, it would resemble a history book. The difference is that history books record the achievements of rulers and the rise and fall of dynasties, while Shui Jing Zhu records cultural relics, landforms, and changes in the world.
Why wasn't Shui Jing Zhu continuously revised? The extreme difficulty of travel in ancient times was likely a major reason. With very limited documentary resources, on-the-ground verification required immense effort and cost. Additionally, the fact that geographic information could only be described in text, lacking the support of scientific theories like map coordinate projection, making mapping extremely inconvenient, was also a significant obstacle.
In today's world of advanced science and technology, the conditions are ready for "re-annotating" Shui Jing Zhu! Therefore, building an industry-leading GIS big data platform, based on meeting the needs of GIS-related industries and "expanding upon the former text" ("布广前文"), enabling everyone to record all the past and changes in the world, allowing the public to collectively "re-annotate" Shui Jing Zhu, is a profoundly meaningful and great undertaking.
If this GIS platform could fortunately, like Shui Jing Zhu, traverse millennia, we believe it would become a tremendous treasure for future generations. This is the reason our company is named "Shui Jing Zhu".
The Origin of Shui Jing and Shui Jing Zhu
Shui Jing (《水经》) is the first Chinese monograph dedicated to describing river systems. Its author and date of compilation have long been disputed. Book of Sui · Treatise on Literature records "Shui Jing in three volumes, annotated by Guo Pu". Old Book of Tang · Treatise on Classics and Books changes the word "annotated" from the Sui record to "compiled", making Guo the author. However, New Book of Tang · Treatise on Arts and Letters attributes it to Sang Qin, and most works after the Song Dynasty follow this attribution. The Summary of the Complete Library of the Four Treasuries states: "Observing its entry on the 'Fu River', which refers to Guanghan as Guangwei, it definitely cannot be from the Han period; in its entry on 'Zhong River', it refers to Jinning as Weining, indicating it precedes the Jin era. Examining the text and phrases, it likely dates to the Three Kingdoms period."
Shui Jing briefly describes 137 major rivers across the country. The original text is just over ten thousand words, quite concise, lacking systematic organization, and provides insufficient detail on the origins, courses, and geography of the river basins.
Shui Jing Zhu (《水经注》) is a famous ancient Chinese geographical work in forty volumes. Its author is Li Daoyuan of the late Northern Wei Dynasty, and it is named for being a commentary on Shui Jing. The text of Shui Jing is about ten thousand words; Tang Liu Dian · Annotation says it "cites the waters under heaven, one hundred and thirty-seven".
Shui Jing Zhu, while appearing to be a commentary on Shui Jing, actually uses Shui Jing as a framework to detail over a thousand large and small rivers, along with related historical sites, anecdotes, legends, and myths. It is a comprehensive and systematic geographical work from ancient China. The book also records numerous stone inscriptions, calligraphy traces, fishermen's songs, and folk ballads. Its writing is brilliant, and its language is elegant and clear, possessing high literary value.
Shui Jing Zhu has been selected by the China World Records Association as China's first hydro-geographical monograph, another Chinese record in ancient hydrology and geography. The entire Shui Jing Zhu contains over 300,000 characters, detailing more than a thousand rivers within China and the related commanderies, counties, cities, products, customs, legends, and history associated with these rivers. The writing style of Shui Jing Zhu is vigorous and elegant; it is both an ancient geographical masterpiece and an excellent work of landscape literature—a geographical work with literary value.
Preface to Shui Jing Zhu [Translation]
The Book of Changes says that Heaven generates Water through the One, therefore the qi is most subtle in the North and becomes the precursor of things. The Records of the Mysterious and Middle states: What is most abundant under heaven is water. It floats the heavens and carries the earth, reaching everywhere from high to low, moistening all things without exception. And when its essence flows and encounters rocks, subtly permeating even the smallest space, within a single morning its moisture can unite with the spiritual realm – no divinity can compare to this. Therefore, even the enlightened cannot fathom its depths or exhaust its vast mystery.
In the past, the Records of the Great Yu described the mountains and seas, broad but not exhaustive; the Treatise on Geography recorded them, brief and not comprehensive; the Book of Documents, the Basic Annals, and the Offices of Zhou were all sketchy; descriptions in the Rhapsodies on Capitals, limited by literary form, failed to fully convey the meaning; Shui Jing, though it roughly connected the main threads, lacked comprehensive coverage. This is the so-called case where each speaks his own mind, but rarely can anyone provide complete guidance.
Now, those who follow maps to seek mysteries listen intently to theories of regional divisions, but those who travel widely across the land seldom achieve clear understanding of the river routes. Even if vaguely recalling previous accounts, one cannot help but feel deeply perplexed. In my youth, I lacked interest in seeking out mountains; as I grew older, I strayed from the nature that inquires about fords. My knowledge falls short of profound classics; my understanding fails in essential breadth. Advancing, I lack the opportunity to infer two things from one; retreating, I lack the wisdom to deduce three corners from one. Studying alone and unheard-of, the ancients lamented such isolation and meagerness; having lost and abandoned books, the perceptive sigh at such wall-gazing ignorance. Seeking depth in silent rooms, asking about distant lands from a closed boat – this too is difficult indeed.
Yet, peeking at the sky through a thin tube or a bamboo calendar tube sometimes brings clarity; drinking from rivers and dipping into the ocean, one can understand their nature according to one's capacity. I thought, having much leisure time, idly letting the years pass by, I would therefore narrate the Shui Jing, expanding upon the former text. The Great Tradition says: Great rivers flow separated, small streams connect to each other, all returning east to the sea. Tracing the inflows and outflows of their branches, examining the paths they traverse along their routes, visiting watercourses and searching channels, I have collected and connected them. Where the Classic has errors, I verify and append corrections; what the text does not record, and what are not constant sources of the rivers mentioned in the Classic, fall outside the scope of this commentary.
But the remote past is obscure, Chinese and foreign dynasties succeeded one another, cities and towns lie empty and ruined, rivers and streams have been altered destructively, different names and distinct labels arose across generations. The concealment and appearance of rivers and channels, maps and books themselves are inconsistent; some, with confused flows, assume misleading names; others, cutting straight across, acquire general designations. Curves intertwine strangely, whirlpools swirl and surge back, paths branch and tangle, the organized system is complex and numerous. Even mastering the Twelve Classics might be difficult to explain fully, let alone minor streams and tiny ripples – they are inherently hard to investigate thoroughly. I can only offer my straightforward views and fully present the theories of geographers. What I do not know, I shall leave unmentioned. The reason for compiling evidence based on this Classic and attaching its essential branches is hopefully to serve as a private aid against errors and oversights, seeking to make consultation easier.
