Feng You-lan pointed out that the philosophy of Zhuangzi was the philosophy of change; Xu Fu-guan, on the other hand, believed that the philosophy itself was incorporated with changes in life in order to achieve true freedom of the mind and the body. Zhuangzi's philosophy was thus clearly associated with ”change”. On this basis, this article explored the relationship between Zhuangzi's philosophy and the idea of change by examining changes that were mentioned in Zhuangzi (book). This allowed us to take a closer look at how Zhuangzi observed and reflected on changes in life and what he learnt and gained from them. In addition, spiritual freedom, which Zhuangzi considered highly important, was discussed in terms of its connection with change in this article.
