The Double Negation Thinking of Cheng Xuan Ying-Analysis of Sub-Commentary of Zhuang Zi

This article deals with a text that is known as the most important sub-commentary of Zhuang-Zi--Nan Hua Zhen Jing Zhu (also known as Sub-Commentary of Zhuang Zi). We shall analyze the academic position of this text and discuss the epistemological and ontological questions found in the Double-Negation School of writing. We shall deal with three important issues in this article: Double negation discourse, sage discourse, and the governing discourse. We will also discuss questions such as why Double Negation School was initiated, what the ultimate meaning of Double Negation is, how Buddhist thought influences double negation thought and how the divine differs from and interacts with the secular. The core of the dissertation will focus on the statement that the ideal ruler (the sage) governs by cultivating himself through the thinking of double negation. We shall also try to initiate some critical points for further study during the discussion: the relationship between Confucian and Taoist Schools during the Han dynasty, as far as the Wei-Jing and Sui-Tang eras, the hierarchy of political and religious affairs, the body and the state, physically or mentally emphasizing viewpoints, body formation in the state building process and the interpretation of Zhuang-Zi by Buddhism, these are hidden in traditional Chinese political philosophy. The Sub-Commentary of Zhuang Zi reflects the political and religious situation and conveys the internal essence of the political discourses of Taoist and Confucian School to Taoist religion. Undoubtedly this writing itself is a part of the process of state formation and a result of the dominance of political power in the Tang dynasty.
