Abstract: From the background of broad existence,man and thing not only has the different existence forms,but also has the correlation.Thing and man,in a limited sense,involves the interaction between human and objects in the external world.According to Chuang-tzu,thing and thing can mutually communicate and convert in ontology;thing and man can also mutually communicate and blend in value.On the basis,Chuang-tzu studied how to communicate between man and thing and believed that the mutual communication between man and thing has a process.This process embodied the words and meaning.At the same time,man must adhere to the way of virtue as the essence in dealing with the thing.
