Abstract: A “theory” is a set of abstract ideas or statements linked in a specific logical format that can be used to interpret relevant empirical facts. “Interpretation” is to find out the reason for a phenomenon to occur. Formally, it is enough to find a direct cause that we think is the cause of the phenomenon. “Fully interpretation” means that the root cause of the phenomenon must be found through continuous tracing. Formally, this means that the specific empirical facts to be interpreted are continuously deduced from relatively more abstract statements or propositions out until the process cannot or does not need to continue. The most abstract and general theoretical statement constitutes the final logical basis for fully interpretation of the factual statement to be interpreted, and its formation is a sign of the relative perfection of the research activities carried out in this field. Strengthening the construction of general theories should be an important task in the construction of social sciences with Chinese characteristics, including sociology.
