Abstract: There is the opposition in Zhuangzi's philosophy of Ji (literally meaning skill or art), which expresses appreciation for Ji that is full of aimless, free artistic spirit, and opposes Ji for secular and utilitarian purposes; Heidegger's Ji has the positive claim who opposes the technical Ji of universal coercive demasking based on the criterion of usefulness to human beings, and takes the Ji of art as the Daoism of salvation. Based on a common understanding of the artistic spirit of uselessness and uncertainty, they eventually reach to the real common from the external opposition, and provides a new interpretation for rethinking and criticizing the modernity, that is, how the modernity does great harm to human living conditions, that is to say, Ji/Skill advancing into Daoism enables people and everything to be free and become what they are.
