Yi Studies February 11, 2012 We know that Qimen Dunjia operates on the principles of Yi Studies. It is an ancient applied operations research and can be applied to various aspects related to planning and layout, such as personnel affairs, construction, strategy formulation, war, etc. At least from a certain perspective, the application rules of Qimen Dunjia are quite similar to modern advanced mathematics. In fact, many areas where advanced mathematics is applied, such as game economics, input-output analysis, macro-management, market forecasting, etc., can be studied from the perspective of Qimen Dunjia. Here, we are not saying which is superior between mathematics and Qimen Dunjia, but rather emphasizing the deep connection between Qimen Dunjia and mathematics. One could even say that Qimen Dunjia is the advanced mathematics of Chinese "Shu Shu".
From the simplest principles of Qimen Dunjia, we can find that the Qimen Dunjia chart itself is a holographic function coordinate system. The basic reference factors of Qimen Dunjia are only three points: time - i.e., the application of Gan Zhi (stems and branches), space - i.e., the application of palace positions, and Shen Sha - such as the nine stars, eight doors, and eight gods, etc. Taking the most widely used Time Family Qimen Dunjia as an example, if we consider the entire nine palaces as a specific functional equation, then the entire setup process can be clearly understood as a mathematical process. Summarize the functional formula based on known factors - i.e., set up the chart according to Gan Zhi; determine the required functional interval based on actual needs and choose the corresponding functional segment (this is often used in economics), i.e., select the palace position (here it's not fixed; single or full disk occupation both belong to the selection of Qimen Dunjia palace positions); substitute the known data to calculate the required information, i.e., participate in the Shen Sha chart interpretation. Here, the overall thinking pattern applied in Qimen Dunjia is essentially the transformation of mathematical thinking patterns. Therefore, not just Qimen Dunjia, but all friends who are reading this article and want to truly master ancient numerology, especially those with zero foundation, should seriously study advanced mathematics.
Compared to mathematics, the symbols in Qimen Dunjia are more abstract. If N in practical economic applications can represent only a few quantities as mathematical symbols, then the "proxy" symbols established by Qimen Dunjia based on Yi Studies have much richer meanings. This makes the formulas in Qimen Dunjia much fewer and more concise than in mathematics. Taking input-output analysis as an example, its basic computational mechanism is matrix operation in linear algebra, from which the mutual interaction relationships among units are mined. The table preparation process and analysis process can be said to be extremely complex. For instance, in municipal analysis tables, just for industrial production, the industries and resources involved can number in the hundreds. If each one needs to be analyzed clearly, the effort required would be immense. However, if using Qimen Dunjia, the formulas are relatively fewer. The basic formulas of Qimen Dunjia are very limited: Heavenly Stems + Heavenly Stems, Eight Doors + Nine Palaces, plus some special formulas like the Nine Evading Techniques and Fu Yin, etc., which are practical and concise. However, regarding its basic principles, the information included in each formula and symbol of Qimen Dunjia is much more complex and very difficult to understand. But the application of Qimen Dunjia is very simple, and the elements for interpreting the chart are clear at a glance (of course, the prerequisite is that you must understand the meanings of these elements).
Samuelson was a great economist because he was the first to introduce mathematics into economic research, elevating traditional economics to a new level. Regarding microeconomics, even without considering psychological factors, the direct relationships between many data in economic models are not significant. At least before Samuelson, few people could explain the relationship between a country's tax adjustment and its deadweight loss. This is not like the butterfly effect, which is still in the hypothesis and experimental stage. Based on the establishment of mathematical formulas, the deep-seated connections between two seemingly unrelated quantities can be manifested. Marx said, "There must be connections between things, including indirect and direct connections." In reality, mathematics itself is a discipline that establishes abstract relationships between things. Apart from mathematics, Qimen Dunjia is also a high-end means of revealing hidden connections between things. The relationships presented by formalized economic mathematics are still confined to an academic field, and the relationships expressed by the butterfly effect can be somewhat accepted (at least they don't seem too absurd). However, the connections established by Qimen Dunjia seem somewhat incomprehensible. In the layout of Qimen Dunjia, the most important relationship is the one between time and Shen Sha. Shen Sha in Qimen Dunjia refers to implicit key factors that were not scientifically proven in ancient times. For example, the moon's motion cycle affects the human growth cycle. Although this connection has been proven now, in ancient times, it belonged to the category of incomprehensible "Shen Sha" factors. It is not hard to imagine that when science continues to develop and discovers more implicit relationships between things, the model of Qimen Dunjia can be further innovated and become even more practical.
The reason for saying this is that the author's current research is limited to Qimen Dunjia alone. Actually, after all this talk, it is not just Qimen Dunjia. All ancient secret methods referred to as "Shu Shu" follow the same principle. Compared to other high achievements such as the Four Great Inventions, the development of ancient Chinese mathematics does not appear particularly prominent. This is because Chinese mathematics uses fewer symbols, yet their meanings are incredibly rich. This leads to very few people being able to practice "Shu Shu," preventing the proper development of mathematics. Given time, if we can combine modern mathematics with ancient "Shu Shu," it will undoubtedly become a milestone creation in the history of "Shu Shu."
