Together with Shi, Zi, and Ji in ”Si Bu”, Jing is seen as the most important classical book in ancient Chinese literature. Two well-know father-and-son history catalogers, Liu Xiang and Liu Xin, mentioned in their work ”Han Zhi” that Xian-Qin Zhuzi should be regarded as the tributary of Liu Jing. This point of view has long been either neglected or misinterpreted by later generations. This paper emphasizes seeing Jing as the whole and the philosophy of Xian-Qin Zhuzi as the segment in the whole). Stating the origins, citations, and the relationship of essence-function of Xian-Qin Zhuzi will also help prove ”Han Zhi”'s accurate point of view.
