Abstract: In Chinese classical thought, corresponding to the understanding and regulation of taste as the essence of things, knowing taste is regarded as the dominant form and core task of cognition. Knowing taste is known through the experience of taste and articulated using taste-related words. The fusion of subject and object is full of subjectivity and uncertainty. Knowing taste aims at taste and develops based on the "taste" paradigm. It is experiential and essential universality. However, the unique one that blends with oneself and produces chemical reactions has always been an important goal of knowing taste. Knowing taste requires the knower to consciously open up and allow all things to pass through themselves, so that oneself can merge with all things and forming a unified whole. From what we know, knowing taste is not only about its object, but also about itself and the symbiotic world of things and themselves. Taste contains Dao(道), knowing taste is enough to know Dao(道), this is the unique feature of Chinese thought.
