Four diagnoses of traditional Chinese medicine

Doctors use sensory functions such as vision, hearing, smell and touch to talk with patients or insiders, and comprehensively understand and systematically grasp all kinds of information related to diseases, thus guiding clinical treatment. The diagnostic methods of traditional Chinese medicine include four methods: looking, smelling, asking and feeling the pulse, which are called four diagnoses. Each of the four diagnostic methods has its own unique function and cannot replace each other. Only by comprehensive application in clinic can we make a correct judgment of the disease.
