Happy Travel is one of the representative works of Zhuangzi, and it is also a masterpiece of a hundred schools of thought. It is full of strange imagination and romantic colors, and combines reasoning with fables and vivid metaphors to form a unique style. "Wandering freely" is also an important aspect of Zhuangzi's philosophy. The whole article repeatedly expounds the idea of nothing to rely on and pursues the absolute freedom of the spiritual world. In Zhuangzi's eyes, everything in objective reality, including people, is antagonistic and interdependent, so there is no absolute freedom. If you want nothing to rely on, you have nothing. Therefore, he hopes that everything will go with the flow, be detached from reality, deny all the functions of human beings in social life, and confuse human life with the survival of all things; Advocate not to dwell on things and pursue unconditional spiritual freedom.
