This study has surveyed the problems raised through the standardization process of differentiation system and searched its solution, reaching the following conclusion. 1. The most serious problem is, most frequently occurred, an wilful application of differentiation system or constitutive classification for disease. 2. To overcome this wilfulness, we must make a definite understanding of the origin and its applicative limit of the theory. 3. And it must be preceded for a correct and objective differentiation to standardize in all choice of the differential diagnostics and its applicative condition. 4. To establish such a corresponding diagnostic scheme, it must be generally agreed on an individuality and inevitability of the suitability to differentiation principles. 5. And, though we can make a prescription through the frequency, degree, and clarified cause of the symptom, its flexibility of application must not be necessarily, ignored. 6. As this study for standardizing the disharmony between liver and pancreas(肝脾不調) shows, accordingly, we must begin by scrutinizing and defining what the chief cause, head, and inevitable symtoms are and discern them from its affinities, making necessarily a great deal attention to minute feelings and degree about its individual symptoms. On the ground of these recognition, we must go further to establish a general standardization and try to get a specific study series.
