The study of "Harmony Thought" in "Zhuangzi" in this article is different from the previous three-part expositions of "Heavenly Harmony", "Human Harmony" and "Heart Harmony". It regards "Zhuangzi" as a systematic documentary interpretation principle. In the book, through the problem of origin and the practice of self-cultivation, the internal context of the theory of "Zhuangzi" and the horizontal connection between the chapters are integrated, and the superiority of the theory of "harmony" in the thought of "Zhuangzi" is proved. And with the help of this "harmony thought" to clarify the division of "qi" in the context of "Zhuangzi", and at the same time include the discussion of the relationship between "mind-qi", and this discussion also affects the theory of "harmony" in this article.
The construction of the theory of "harmony" mainly started from the inquiry into the topic of "reaching people's minds; gaining popularity", thus extending the whole literature on how to practice "harmony". Here, in the interpretive thinking that uses the objective reality as the support for the universality and absolute principle of interlinking subject and object, metaphysics, internal and external, from the argument of subjectivity, the theory of understanding, the discussion of the relationship between mind and spirit, to the guarantee of objective and real Daoism, which is closely linked to the content of the theory of "practical harmony", hereby corresponds to the interpretation validity of "Zhuangzi" that "the inner sage is the outer king". The analysis of the "harmonious thought" of "Zhuangzi" not only involves the understanding of the rationale of the document and the establishment of the theoretical framework, but also the "ethics" (relationship between things and me) in "Zhuangzi" from the perspective of the classical new interpretation. In order to construct a set of ethical viewpoints with Zhuangxue characteristics, as such, through the ethical view with the goal of "harmony", it provides a discussion on the topic of "harmony category" for the comparison of the theoretical systems of Taoist thought and even Chinese philosophy. On this basis, discussions with "harmony" as the core of the domain can expand and converge the continuity of "Zhuangzi" theory.
