Numerical Principles and Auspiciousness — A Detailed Explanation of the Five Grids Analytical Method (Part II)

I. From Numbers to Symbolic Meaning: The Essence of Numerical Principles

In the previous chapter, we completed our study of the calculation methods for the Five Grids (五格), mastering the derivation rules for the Heaven Grid (天格), Human Grid (人格), Earth Grid (地格), Outer Grid (外格), and Total Grid (总格), and developing a preliminary understanding of the Five Elements (五行) relationships within the Three Talents (Heaven, Human, Earth) (三才) configuration. However, calculating the numbers of the Five Grids is only the first step — what do these numbers actually signify? What Auspicious (吉) or Inauspicious (凶) information does each one carry? And how do the Five Grids work in concert to form a comprehensive judgment of a given name?

These are precisely the questions this chapter will answer.

In the Five Grids analytical method, every number derived from Stroke count (笔画) calculations is not merely a mathematical symbol, but rather a "Numerical principle" (数理) — that is, the symbolic meaning and destined implication embedded within the number itself. This concept is rooted in the traditional Chinese mode of thinking through images and numbers: the Book of Changes uses numbers to generate hexagrams and images to illuminate principles, and numbers and images have never been separable. One is the origin of the Supreme Ultimate; two represents the division of Yin and Yang (阴阳); three establishes the Three Talents of Heaven, Human, and Earth... each number is a projection of the rhythmic workings of the cosmos.

The Five Grids analytical method assigns each of the eighty-one numbers from 1 to 81 a specific symbolic meaning and auspiciousness rating, forming a complete system of Numerical principles. Beyond 81, the cycle begins again — 82 is equivalent to 2, 83 to 3, and so forth. This cycle is not arbitrarily defined, but rather embodies the idea of "nine nines returning to one": nine is the pinnacle of Yang numbers, nine times nine equals eighty-one, all things reach their extreme and return to their origin, cycling endlessly in perpetual regeneration.

II. A General Overview of Auspiciousness and Inauspiciousness Across the Eighty-One Numerical Principles

The eighty-one Numerical principles form the core reference system of the Five Grids analytical method. Each number has its own unique symbolic name and auspiciousness rating. According to traditional classification, the eighty-one numbers can be divided into five grades: Greatly Auspicious, Auspicious, Half-Auspicious and Half-Inauspicious, Inauspicious, and Greatly Inauspicious. Below, a general classification overview is presented first, followed by an explanation of the shared symbolic meanings within each grade, with representative numbers selected for detailed illustration.

Greatly Auspicious numbers: 1, 3, 5, 8, 11, 13, 15, 16, 21, 23, 24, 25, 29, 31, 32, 33, 35, 37, 39, 41, 45, 47, 48, 52, 57, 61, 63, 65, 67, 68, 81

Auspicious numbers: 6, 7, 17, 18, 27, 30, 38, 51, 55, 58, 71

Half-Auspicious and Half-Inauspicious numbers: 10, 22, 26, 36, 40, 42, 43, 49, 50, 53, 56, 60, 66, 69, 72, 73, 75, 77, 78

Inauspicious numbers: 2, 4, 9, 12, 14, 19, 20, 28, 34, 46, 59, 62, 64, 70, 74, 76, 79, 80

Greatly Inauspicious numbers: 44, 54

Note: Individual numbers may be classified differently across various Chinese Name Analysis (Xingmingxue) (姓名学) texts. For example, the number 27 is categorized as Half-Auspicious and Half-Inauspicious rather than Auspicious in some texts, owing to differences in scholarly emphasis when interpreting its symbolic meaning. This volume uniformly adopts the classification presented above. Readers who encounter occasional discrepancies when consulting other texts are encouraged to note and compare them, but in practical application one should select a single version and maintain internal consistency.

Shared Symbolic Meanings Within Each Grade

Shared characteristics of Greatly Auspicious numbers: Greatly Auspicious numbers universally embody images of vigorous development, solid stability, leadership authority, and accomplished success. In terms of symbolic meaning, these numbers are predominantly associated with pioneering endeavors, proactive advancement, abundant harvest, and wholesome fulfillment, suggesting flourishing undertakings, a solid foundation, and enduring blessings. Number 1 is the source from which all things are generated, symbolizing independence and drive; number 24 carries the image of building a fortune from nothing; number 81, as the end of the cycle that simultaneously marks a new beginning, contains the meaning of all things renewed. When Greatly Auspicious numbers appear in the Human Grid or Total Grid, they are regarded as the most ideal configuration.

Shared characteristics of Auspicious numbers: Auspicious numbers are generally positive in tendency, though somewhat less powerful than Greatly Auspicious numbers. Their symbolic meanings lean toward steadiness, gentleness, and sustained development. While they lack the robust and vigorous quality of Greatly Auspicious numbers, their strength lies in stable continuity with few dramatic highs or lows. Number 6 carries an image of tranquil harmony, while number 18 suggests the successful management of affairs and the attainability of ambitions. Auspicious numbers are well-suited for individuals who aspire to a smooth and settled life.

Shared characteristics of Half-Auspicious and Half-Inauspicious numbers: These numbers possess a dual nature — they contain both the potential for upward development and the hidden risk of setbacks and reversals. Their symbolic meanings are frequently associated with change, contradiction, hardship followed by sweetness, or initial ease followed by bitterness. Number 10 carries an image of emptiness and final endings, yet also holds within it the potential for reversal and renewal — ten is a number of fullness; what is full overflows and returns to zero, suggesting that after an ending comes a new beginning. Number 40 carries an image of unstable fluctuation, but if the Three Talents (Heaven, Human, Earth) configuration exhibits a pattern of Mutual generation (productive cycle) (相生), its negative tendencies can be mitigated. The ultimate expression of numbers in this category depends especially on the overall Five Grids configuration and the Three Talents (Heaven, Human, Earth) relationship.

Shared characteristics of Inauspicious numbers: Inauspicious numbers are symbolically associated with obstruction, solitude, turbulence, and depletion. These numbers suggest that one's life may encounter considerable external obstacles or internal conflicts — such as tendencies toward an inflexible personality, disharmonious relationships, or career setbacks. Number 2 carries an image of division and dependency; number 14 suggests instability and frequent frustrations; number 34 carries an image of shortsightedness and ruinous disorder. When Inauspicious numbers appear in the Human Grid, particular vigilance is warranted, though their negative influence can be partially mitigated if the Three Talents (Heaven, Human, Earth) configuration is well-arranged.

Shared characteristics of Greatly Inauspicious numbers: Greatly Inauspicious numbers are those among the Inauspicious numbers with the most concentrated destructive force. Their symbolic meanings are predominantly associated with accumulated hardship, frequent calamities, and frustrated aspirations. Number 44 carries an image of vexation, depression, and hidden danger; number 54 suggests a life of many difficulties and obstructed ambitions. Regardless of which Grid a Greatly Inauspicious number appears in, it is something that Name selection (取名) should make every effort to avoid.

Number 54 — Abundant difficulties and misfortunes; illness, weakness, and shortened life. This number carries an image of many calamities and obstructed ambitions. It is a Greatly Inauspicious number that Name selection (取名) should make every effort to avoid.

The above constitutes the systematic classification and individual explanation of the eighty-one numbers across five grades. In practice, readers may consult the symbolic meaning and auspiciousness rating for each of the numbers appearing in their Five Grids. It is important to grasp one fundamental principle: the auspiciousness or inauspiciousness of Numerical principles is not an absolute either-or judgment, but rather a symbolic indication of tendency. Greatly Auspicious numbers suggest a tendency toward smooth progress and development; Inauspicious numbers suggest the possibility of obstacles and challenges. The final judgment, however, must always be placed within the systemic context of the Five Grids as a whole and the Three Talents (Heaven, Human, Earth) configuration.

III. The Emphasis and Significance of Each Grid's Numerical Principles

The same number carries different areas and degrees of influence depending on which Grid it appears in. This is a critically important principle within the Five Grids analytical method that is frequently overlooked.

Heaven Grid Numerical Principles: The Root of Innate Endowment — Primarily for Reference

The Heaven Grid (天格) is determined by the Stroke count (笔画) of the Surname (family name) (姓) and represents innate fortune and the foundation of the family lineage. As noted in the previous chapter, the Heaven Grid is something an individual cannot choose — those who share the same Surname (family name) share the same Heaven Grid, yet their fates may differ greatly. Therefore, the auspiciousness or inauspiciousness of the Heaven Grid's Numerical principles has a relatively weak direct influence on the individual, and its primary function is to play the role of "Heaven" within the Three Talents (Heaven, Human, Earth) configuration. When undertaking Name selection (取名), there is no need for anxiety if the Heaven Grid's Numerical principles are unfavorable, as it is an immutable innate condition. The critical task is to neutralize or compensate through the thoughtful arrangement of the Human Grid and Earth Grid.

Human Grid Numerical Principles: The Master of One's Lifetime — The Essential Core

The Human Grid (人格) is the absolute core of the Five Grids system, representing a person's primary fortune, the foundational coloring of their character, and the principal thread of their life's journey. The auspiciousness or inauspiciousness of the Human Grid's Numerical principles is the highest-priority consideration in Name selection (取名).

Those whose Human Grid Numerical principles are Greatly Auspicious tend toward a more complete character, steadfast will, and greater likelihood of career success. Those whose Human Grid Numerical principles are Inauspicious may exhibit certain tendencies toward imbalance in character — too rigid and easily broken, too yielding and easily swayed, too proud and difficult to accommodate with others, and so forth. Of course, Numerical principles are only a form of symbolic indication; they cannot determine a person's character. However, within the interpretive framework of Chinese Name Analysis (Xingmingxue) (姓名学), the character tendencies implied by the Human Grid's Numerical principles serve as an important reference for analysis.

Earth Grid Numerical Principles: The Foundation of Youth — An Image of Early Fortune

The Earth Grid (地格) represents the fortune of the youth and young adult years, the emotional foundation, and the affinity with one's children. Auspicious Earth Grid Numerical principles suggest a solid foundation in early life, a harmonious family, and smooth academic progress. Unfavorable Earth Grid Numerical principles suggest that one may encounter setbacks in early life or that some element of instability exists within the family environment.

Within the Three Talents (Heaven, Human, Earth) configuration, the Earth Grid occupies the position of "Earth," serving as the support and foundation for the Human Grid. The Five Elements (五行) relationship between the Earth Grid and the Human Grid is especially critical — when the Earth Grid generates the Human Grid, the foundation is solid and provides powerful support; when the Earth Grid overcomes the Human Grid through Mutual overcoming (destructive cycle) (相克), the foundation becomes a burden dragging down the primary fortune.

Outer Grid Numerical Principles: Social Interactions and Circumstances — The Interpersonal Environment

The Outer Grid (外格) represents social fortune and the external environment. Auspicious Outer Grid Numerical principles suggest harmonious interpersonal relationships, ease and fluency in social settings, and the ready ability to obtain others' support and assistance. Inauspicious Outer Grid Numerical principles suggest that one may encounter misunderstanding, exclusion, or isolation in personal relationships.

The Outer Grid occupies a relatively secondary position among the Five Grids. However, given the increasingly prominent importance of interpersonal relationships and social abilities in contemporary society, the reference value of the Outer Grid has risen accordingly. For those engaged in professions requiring extensive interpersonal interaction — such as public relations, sales, and management — the auspiciousness or inauspiciousness of the Outer Grid's Numerical principles merits particular attention.

Total Grid Numerical Principles: The Later Fortunes and Final Chapter — The Overall Pattern of a Lifetime

The Total Grid (总格) is the sum of the Stroke count (笔画) of all characters in both the Surname (family name) (姓) and Given name (名), representing the fortune of the middle and later years and the overall pattern of one's entire life. Those whose Total Grid Numerical principles are Auspicious will tend toward a fulfilling later life even if their early years were turbulent; those whose Total Grid Numerical principles are Inauspicious, even if they achieve early success, must remain vigilant against the undercurrents that may arise in the second half of life.

In traditional Chinese culture, "a good beginning and a good ending" is the highest praise one can offer for a life well-lived. What the Total Grid concerns is precisely this concluding chapter of life — the ultimate achievements of one's career, the peace and stability of family in old age, and the harmonious resolution of one's spiritual life. Therefore, in Name selection (取名), the auspiciousness or inauspiciousness of the Total Grid's Numerical principles should receive ample consideration alongside the Human Grid.

IV. A Comprehensive Evaluation of the Three Talents (Heaven, Human, Earth) and Five Grids: The Core of Systemic Analysis

At this point, a question may arise in the reader's mind: if all five of the Five Grids are selected to carry Auspicious numbers, does that not guarantee that everything will be perfectly favorable?

The answer is no. The essence of the Five Grids analytical method lies not in the quality of individual numbers within a single Grid, but in the overall harmony of the Five Elements (五行) relationships among the Five Grids — and in particular, within the Three Talents (Heaven, Human, Earth) configuration. Even if a name's Five Grids each individually carry Auspicious (吉) numbers, if
