This article aims to explore the thought system of Zheng Xuan and his annotations characteristics through in-depth research on "Zheng Zhi". As a famous Confucian scholar in the Han dynasty, Zheng Xuan's academic achievements and influence are far-reaching, and "Zheng Zhi", as an important carrier of his academic thoughts, provides valuable materials for understanding his thoughts.In the introduction, this article first introduces the research background and purpose, pointing out the important position of Zheng Xuan's thought in the history of classics, as well as the value of "Zheng Zhi" as an important document for studying Zheng Xuan's thoughts. Then it summarizes previous research on Zheng Xuan's thought and "Zheng Zhi" by scholars, clarifying their research results. In Chapter Two, the work of editing and collecting fragments of "Zhengzhi" was conducted, which was divided into various parts such as "Yizhi", "Shuzhi", "Shigongzhi", "Zhouli Zhi", "Yili Zhi", "Liji Zhi", "Chunqiu Zhi", and "Zhuanqizhi" etc. Using corpus linguistics methods, the content of each part was carefully segmented and sorted out. This work not only helps us better understand the overall content of "Zhengzhi", but also provides a foundation for further research in subsequent chapters. Chapter 3 provides a brief summary of the basic situation of the "Zhengzhi" literature from a statistical perspective, while using theoretical models such as graph machine learning and word embeddings to explore the connotations of Zheng Xuan's Confucian thought, pointing out his basic characteristics of focusing on issues such as "geography" and "history".Chapter four deeply explores the perspective of geography in "Zheng Zhi". Through the analysis of Zheng Xuan's "Nine Regions" perspective, this chapter explores his unique insights in explaining classics. His seemingly idealistic and reluctant explanations actually implied a position of "text-centric". Chapter five focuses on the ancient history perspective in "Zheng Zhi". Through analyzing Zheng Xuan's cognition of history and the concept of Yu Xia Yin Zhou rituals used by him to reconcile contradictions between texts, this chapter reveals how his ancient history perspective and understanding of ancient ritual systems influenced his annotation work. Chapter six analyzes Zheng Xuan's academic thoughts from the perspective of annotation characteristics. Through combing the passages of "Zheng Zhi", this article summarizes some characteristics of annotating classics, including differences in time sequence, comparing the present with the past, and unifying text and reality. In the conclusion, this article summarizes the core feature of Zheng Xuan's thought, which is the compound method of studying the classics based on both text and reality, and also raises some questions and prospects for future research. Through in-depth research on "Zheng Zhi", we can not only better understand Zheng Xuan's academic thoughts, but also have a deeper understanding of the development of Confucianism in the Han dynasty.
