Abstract: “Etherealness”is partially consistent in the process of cross-infiltration of Taoism，Buddhism，and metaphysics. As an intuitive understanding of perceptual life，it is not only the external manifestation of the subject’s empty and quiet state of mind，but also the subject's spiritual pursuit of seclusion and freedom.“Etherealness”is both an art form and an aesthetic realm. At the time of its creation，it condenses the aesthetic taste and life consciousness of the Chinese ancients. It is an aesthetic experience of the subject in aesthetic consideration，which in turn highlights the unique aesthetic and artistic spirit of the Chinese nation.

Key words: etherealness, ethereal beauty, aesthetic category, ethereal realm, poetic thinking
