1.2 Current status of domestic and international research

In the academic circles at home and abroad, studies on the Eight Character Numerology have accumulated certain results. These studies have analyzed and explored the Eight Character Numerology in depth from different angles and levels.

Foreign scholars' studies of the Eight Character Fate are mostly from the perspectives of cultural anthropology and psychology. They focus on the manifestations of Bazi fortune telling in different cultural contexts and its influence on individual psychology and behavior. For example, some scholars have explored the spread and mutation of the Eight Character Numerology in the East Asian cultural circle, revealing its adaptability and vitality in different geographical and cultural environments. Other scholars have analyzed the mechanism of Bazi numerology's influence on individuals' self-perception, motivation and behavioral decision-making from the perspective of psychology, believing that Bazi numerology can, to a certain extent, satisfy people's psychological needs for self-understanding and future exploration.

Domestic scholars' research on Bazi fortune telling focuses more on the excavation and organization of the theoretical system and the evaluation of practical application. They are committed to sorting out the historical development of Bazi numerology and explaining its philosophical foundation and theoretical connotation. At the same time, some scholars pay attention to the practical application of Bazi fortune telling in modern society, and evaluate its predictive effect and practical value through case studies and empirical research. These studies have not only enriched the theoretical system of Bazi numerology, but also provided strong support for its practical application.

There are still some shortcomings in the current study. First of all, the historical development of Bazi fortune-telling is not clear and systematic enough. Although there have been many studies on the historical origin and development process of Bazi numerology, they tend to focus on a certain period or a certain aspect of the discussion, and lack of holistic and coherent research. Secondly, the construction of the theoretical system of Bazi fortune-telling needs to be further improved. The existing theoretical system is mostly based on the organization and interpretation of traditional literature, while there is relatively little reference to and integration of modern scientific and philosophical ideas. To a certain extent, this limits the innovation and development of the theory of Bazi numerology.

In view of the above shortcomings, this paper attempts to further deepen the research on the historical development of Bazi fortune-telling on the basis of the existing achievements. By utilizing multidisciplinary research methods such as history, philosophy and culture, this paper aims to comprehensively sort out the historical development of Bazi fortune-telling, and reveal its inner logic and development law.

Chapter 2 The Origin of Word Numerology and the I Ching

2.1 Origin of Word Numerology

The origins of Bazi fortune telling, a unique method of destiny prediction in ancient China, can be traced back to the ancient astronomical calendar and divination culture. In ancient times, in order to survive and reproduce, people were full of curiosity and reverence for all kinds of phenomena in the natural world. They looked up to the stars and down to the mountains and rivers, trying to find patterns and guidance from heaven and earth. It was against this background that the astronomical calendar came into being, becoming an important tool for the ancients to grasp time and guide their farming and life.

With the passage of time, the ancients became more and more refined in their observation of astronomy, and they found that there seemed to be a subtle connection between human destiny and certain astronomical phenomena, especially the celestial phenomena at the time of birth. This connection was gradually perceived by some wise men and they began to try to interpret and predict the trend of an individual's destiny through the combination of Heavenly Stems and Earthly Branches. The Heavenly Stems include ten symbols such as A, B, C, D, etc., while the Earthly Branches include twelve symbols such as Zi, U, C, D, etc., which are used in a cyclical manner and together constitute the traditional 60 A Zi chronology.

In Bazi fortune telling, "eight characters" refers to the combination of heavenly stems and earthly branches corresponding to the year, month, day and hour of a person's birth. These eight characters are believed to contain the code of a person's destiny, and by interpreting these codes, one can gain insight into a person's character, fortune, and possible future misfortunes and misfortunes. This concept was widely recognized and spread in ancient societies, gradually forming a complete set of destiny doctrines.

The origin of Bazi fortune telling is closely linked to the ancient astronomical calendar, which is not only an embodiment of the ancient people's exploration of the universe and destiny, but also reflects the ancient society's deep understanding of the relationship between human beings and nature. In this way, people tried to find a hint of guidance and solace in the complicated journey of life, in order to be able to better cope with future challenges and opportunities.

Although Bazi numerology occupies an important position in traditional Chinese culture, it is not a scientific method of prediction. Its accuracy and validity have been much debated. Regardless, it is deeply imprinted in the historical memory of the Chinese nation as part of ancient Chinese culture.

In today's society, although technology is changing rapidly and people's views on fate are becoming more and more rational and scientific, Bazi fortune telling still retains a certain influence in certain regions and groups. It is not only a tool for destiny prediction, but also carries people's curiosity and exploration of the unknown future, as well as the inheritance and respect for traditional culture.

The origin of Bazi fortune telling is closely linked to the ancient astronomical calendar and divination culture. As a crystallization of ancient Chinese wisdom, it not only embodies the ancient people's profound understanding of the universe and destiny, but also reflects their pursuit of a harmonious coexistence between man and nature. Although its scientificity and accuracy are debatable, the historical value and cultural significance of Bazi fortune telling, as an important part of traditional Chinese culture, cannot be ignored.

2.2 Influence of the I Ching on Eight Character Numerology

As a treasure of ancient Chinese philosophy, the I Ching not only explores the laws of the universe, but also invisibly penetrates into all kinds of academic fields, including the influence on the eight-character numerology. This influence is mainly reflected in the inheritance of philosophical ideas and the symbol system.

The I Ching emphasizes the concept of balance between yin and yang, which is prominently reflected in the Eight Character Fate. According to the Eight Character Numerology, a person's destiny is influenced by the five elements of yin and yang, and the balance of yin and yang is the key to a harmonious destiny. This balance is not only reflected in an individual's natal chart, but also throughout the Eight Character Numerology's understanding of the entire universe. For example, when interpreting the Eight Characters, a fortune teller will focus on the interrelationship between the Five Elements and the harmonization or lack thereof of Yin and Yang, so as to determine a person's personality traits, career development and social relationships .

The symbol systems in the I Ching, such as the eight trigrams and the 64 hexagrams, provide a rich symbolic meaning and interpretive framework for the Eight Character Numerology. The combination of Heavenly Stems and Earthly Branches in the Eight Character Fate is actually a combination of symbols, which represent different meanings and symbols. The combinations and variations of these symbols reflect a person's destiny trend and potential characteristics. When interpreting the Eight Characteristics, the fortune teller will combine the symbolism of these symbols and their interrelationships to reveal the code of a person's destiny .

The methods of prediction in the I Ching are also similar to the Eight Character Numerology. Although there are various methods of prediction in the I Ching, some of its principles coincide with the Eight Character Numerology. For example, the idea of "change" in the I Ching emphasizes the constant change and development of things, which echoes the mutability and plasticity of destiny in Bazi numerology. At the same time, the criteria for judging good and bad fortune in I Ching also provide reference for the prediction of good and bad fortune in Bazi numerology .

The influence of the I Ching on Bazi numerology is far-reaching. It not only provides guidance on the philosophical thinking of Bazi numerology, but also provides it with a rich system of symbols and methods of prediction. This influence enables the Eight Character Numerology to reveal more deeply and comprehensively its inner laws and characteristics when interpreting people's destinies. At the same time, it also makes us cherish and pass on this ancient and wise cultural heritage.

Although the I Ching and Bazi numerology are inextricably linked, they are still academically different. Bazi fortune-telling focuses more on practical application, predicting one's destiny through the combination of Heavenly Stems and Earthly Branches, while the I Ching focuses more on philosophical thinking and the exploration of the laws of the universe. Therefore, in the process of research and application, we should clearly define the boundaries and focuses of the two, so as to better utilize their respective advantages and values.

In practical application, many fortune tellers will combine the principles of the I Ching and the techniques of Eight Character Numerology to provide their clients with more accurate destiny interpretations and advice. This integrated application not only enriches the connotation and extension of Eight Character Numerology, but also improves its accuracy and practicality in practical application.

In the future, with the development of science and technology and the integration of cultural exchanges, the study of Eight Character Fate and the I Ching will usher in more opportunities and challenges. We expect more sparks and inspirations to come out of the intermingling of these two ancient disciplines to provide more wisdom and insights for the exploration of human destiny and guidance of life. At the same time, we should also pay attention to how to combine these traditional wisdoms with modern technology to better serve the ne

2.3 Commonalities between Word Numerology and the I Ching

As two important components of traditional Chinese culture, Bazi fortune telling and the I Ching show a profound commonality on many levels. This commonality is not only reflected in the common exploration of the origin of the universe and the laws of operation of all things, but also in the similarity of the use of symbol systems to explain complex philosophies, as well as the common emphasis on the core philosophical ideas of the balance of yin and yang, and the interplay of the five elements.

In the exploration of the origin of the universe and the laws of operation of all things, both the Eight Character Numerology and the I Ching show a strong philosophical interest. Through the combination of the Heavenly Stems and Earthly Branches, Bazi fortune telling reveals the subtle connection between individual destiny and the time, place, and people, while the I Ching, through the evolution of the trigrams, explains the natural laws of the universe, such as yin and yang, and the birth of the five elements. Both, in their own unique ways, try to unravel the operating logic behind everything in the universe .

In terms of the use of symbol systems, the Eight Character Numerology and the I Ching also show a high degree of similarity. The Eight Trigrams of Fate uses the Heavenly Stems and Earthly Branches as the symbolic basis, symbolizing the diversity and complexity of individual destinies through different combinations; whereas the I Ching uses the Eight Trigrams and the Sixty-four Hexagrams as the symbolic system, illustrating the interrelationships and development trends of all things in the world through the changes of the hexagrams. These symbol systems are not only rich in symbolic meaning, but also provide a broad space for interpreters to interpret .

Bazi numerology and the I Ching also share deep commonalities in philosophical thought. Both emphasize the importance of the balance of yin and yang, and believe that the imbalance of yin and yang is the root cause of the disorder of all things. At the same time, the idea of interactions between the five elements is also fully reflected in both, which is used to explain the interactions and influences between things. These philosophical ideas not only provided a solid theoretical foundation for the Eight Character Numerology and the I Ching, but also had a profound impact on the overall development of traditional Chinese culture .

The commonalities between the Eight Character Numerology and the I Ching in terms of ideology and methodology are manifested at various levels, including the common exploration of the origin of the universe and the laws of the operation of all things, the similarity of the use of symbol systems to explain complex philosophies, and the common emphasis on the core philosophical concepts of yin and yang balance, and the interplay of the five elements. These commonalities not only reveal the intrinsic connection between the two, but also provide useful perspectives for our in-depth understanding of traditional Chinese culture.

In practical application, Bazi fortune telling often draws on the philosophical ideas and symbol systems of the I Ching to enrich its theoretical system and practical methods. For example, when interpreting individual destiny, Bazi numerology practitioners will refer to the trigrams and lines in the I Ching in order to more comprehensively grasp the development trend and potential opportunities of destiny. This cross-field integration not only enhances the practical value of Bazi fortune-telling, but also further consolidates its important position in traditional culture.

The philosophical ideas of the I Ching also provide profound insights into the eight-character numerology. For example, the I Ching emphasizes that "Heaven walks with health, and a gentleman is self-reliant", encouraging people to maintain a positive and enterprising attitude in the face of the challenges of destiny. This idea is fully reflected in Bazi fortune telling. In reading destiny, fortune tellers often emphasize the importance of personal efforts, encouraging helpers to improve their destiny through their own efforts. This positive attitude not only helps to boost people's self-confidence, but also injects positive energy into society.

Chapter 3: The Evolution of Word Numerology

3.1 Development of Ancient Eight Character Numerology

As a unique cultural phenomenon, Bazi fortune telling was deeply rooted in people's lives in ancient societies. Its development can be said to have a long history, dating back to the pre-Qin period at the earliest. However, it was during the Song, Yuan, Ming and Qing dynasties that the Eight Character Fate was really systematized and widely spread.

In the Song Dynasty, with the rise of rationalism and the deepening of Confucianism, people's exploration of fate and heavenly ways became more and more in-depth. During this period, the Eight Character Numerology was greatly developed, not only the theoretical system became more perfect, but also the practical application became more and more extensive. Xu Ziping and other fortune-tellers came to prominence during this period, and they systematically organized and interpreted Bazi fortune-telling, which made this study closer to people's lives.

In the Yuan Dynasty, Bazi numerology was further integrated with Taoism, Buddhism and other religious ideas, forming a unique concept of numerology. Scholars such as Wan Minying, on the basis of inheriting the achievements of their predecessors, carried out more in-depth studies on the Eight Character Numerology and put forward many novel and unique insights. These studies not only enriched the connotation of Bazi numerology, but also laid the foundation for its prosperity in the Ming and Qing dynasties.

During the Ming and Qing dynasties, the Eight Character Fate was at its peak. During this period, with the prosperity of the society and the flourishing of culture, people's concern for fate reached an unprecedented height. Bazi numerology not only became a popular cultural phenomenon, but was also widely used in the fields of marriage matching, career guidance and disease prediction. Many writers and writers have also been involved in the study of fortune telling, combining it with poems and songs, giving the Eight Character Numerology more cultural connotations and artistic flavor.

In this long process of development, Eight Character Numerology has always been closely connected with the social background and cultural atmosphere. The political, economic and cultural factors of different historical periods have all had a profound impact on the development of Bazi numerology.

Through the study of the historical development of Bazi numerology, we can gain a deeper understanding of the ideological concepts and cultural characteristics of the ancient society, and also provide useful reference and inspiration for the modern society.

3.2 Formation and Characteristics of the Zi Ping Doctrine

Before we delve into the formation and characteristics of the Zi Ping Doctrine, it is necessary to understand the figure of Xu Zi Ping and his contributions to the field of Bazi numerology. Xu Ziping, as the founder of the Ziping Doctrine, not only deepened people's understanding of Bazi numerology, but also promoted the development of this field. Through in-depth study of a large number of numerology cases, Xu Ziping refined a systematic method of numerology analysis, which not only contains profound philosophical thoughts, but also embodies rigorous logical reasoning.

When analyzing fortune cases, Xu Ziping pays special attention to the interrelationships between the fortune and the great fortune and the current year. He believes that people's destiny is not static, but changes with time and environment. This dynamic perspective makes the analysis of the Eight Character Fate closer to reality and more instructive. At the same time, Xu Ziping also emphasized the key role of the five elements in destiny. Through detailed analysis of the relationship between the five elements, he reveals how one's destiny is affected by the power of the five elements, and how one can optimize one's destiny by adjusting one's behavior and environment.

It is on the basis of these innovative ideas and methods of Xu Ziping that the Ziping Doctrine was gradually formed and developed. This doctrine not only systematically integrates the results of previous numerology research, but also incorporates new ways of thinking and analyzing, making the analysis of Bazi numerology more comprehensive and in-depth.

The characteristics of Zi Ping doctrine are mainly reflected in the following aspects: firstly, it is highly systematic, capable of organically combining various elements of destiny to form a complete analytical framework; secondly, it pays attention to the scientific nature, revealing the mysteries of destiny through rigorous logical reasoning and empirical analysis; lastly, it emphasizes on practicability, aiming to provide people with concrete and feasible suggestions for optimizing destiny.

It is because of these characteristics that the Zi Ping doctrine has had a far-reaching impact in the field of eight-character numerology. It not only provides valuable theoretical resources and analytical tools for later researchers, but also offers a new perspective for the general public to examine and understand their own destinies. Under the guidance of the Zi Ping Doctrine, people can more clearly recognize the characteristics and laws of their own destiny, and thus make more informed decisions and actions. This is precisely the reason why the doctrine of Zi Ping has survived for thousands of years and still has a strong vitality.

Chapter 4 Theoretical System and Practical Application of Word Numerology

4.1 Theoretical System of Word Numerology

The theoretical system of Bazi numerology is a profound and interrelated framework that covers a number of levels and elements. Among them, the Heavenly Stems and Earthly Branches, the interplay of the Five Elements, and the balance of Yin and Yang form the basis of its theory, while the analysis of the Fate Bureau and the projections of the Great Luck and the New Year are the application of its core theories.

The Heavenly Stems and Earthly Branches, as the cornerstones of the Eight Character Numerology, are a unique way of recording time in ancient China. The Heavenly Stems include ten symbols such as A, B, C and D, while the Earthly Branches contain twelve symbols such as Zi, U, Yin and Mao. They are used in a cyclical manner, and together they form the Jizi dating system, which is a cycle of sixty years. In Bazi numerology, the Heavenly Stems and Earthly Branches not only represent the flow of time, but also symbolize the changes in the energy of the universe, and are the starting point for the analysis of an individual's destiny.

The theory of the five elements occupies an important place in the Eight Character Numerology. The Five Elements, i.e. Wood, Fire, Earth, Gold and Water, are mutually reinforcing and maintain the balance of nature. In numerology, the Five Elements are used to analyze an individual's personality traits, health, and career development. Through the relationship between the five elements, one can gain insight into the challenges and opportunities that an individual may encounter at different stages of his or her life.

The balance of yin and yang is the ideal state pursued by Eight Character Numerology. Yin and Yang, represent the two sides of things, such as heaven and earth, male and female, motion and static. In numerology, the balance of yin and yang means the harmony and smoothness of an individual's destiny. If yin and yang are out of balance, it may lead to personal difficulties in health, career and other aspects. Therefore, adjusting the balance of yin and yang becomes the key to improving one's fate.

Fate analysis is one of the core elements of Bazi fortune telling. It reveals an individual's innate endowments and potential traits by analyzing the combination of Heavenly Stems and Earthly Branches at the time of birth, i.e. the Eight Characters of the Birth. Each character in the fortune is rich in information, such as character, talent, health condition, etc.. By interpreting this information, the fortune teller provides targeted advice and guidance to the seeker.

Dazhun Liuyan projection is an important method of predicting future fortune in Bazi numerology. Dazhan, the changes in fortune that an individual experiences at different ages.
