As for the concept of"Untruth"in the Chapter Heaven and Earth of Chuang Tzu,many people have interpreted it since ancient times.From the perspective of Chinese traditional image thinking,it is understood as a virtual image which is seemingly tangible but without its form and entity.From the perspective of nothing,it is also interpreted as"No-mind"and"No Trace".Combining the previous double interpretation of"Image"and"Nothing"perspective,to understand the concept of"Untruth"as the image of"No-mind"and"Slightness".That is to say,the image of"No-mind"will be obtained when unconsciously.At the same time the image of"No-mind"itself is a kind of"Slightness"like,which is getting"Truth"before a harbinger.
