Some basic concepts and basic questions of management were studied. The two terminologies guanli (including management, administration, supervision, etc.) and guanli science (generalized management science) have obvious differences in Chinese and English. In Chinese they are broad senses while in English are narrow senses. The simplified translations lead to several different meanings and confusions in Chinese academia. To clarify the Chinese meanings of these terminologies, four definitions are put forward: 1.Guanli activity is the second kind of human activities serving for the first kind of activities (i.e. operating activities); 2.The public guanli-activities of a group are called guanli works; 3.Some staffs appointed by an organization are called guanliers who are specially doing the guanli works;4. Guanli Science is the sum total of man's knowledge of the rules of guanli activities and guanli works, while is a knowledge system with rich content. We hope to set up the Chinese school of modern guanli science.
