The basic principles of systematical thinking with an eye to its application take optimization as the primary objective. Based on the principle of integrity of the system as the most significant and essential feature, study style construction is considered to be system engineering. And in connection with the principle of relevance for the system, study style construction is characterized by and reflected in the whole process of education instead of a kind of temporary, periodic and partial work. All aspects of work are involved in colleges and universities, which are in need of active coordination, participation and support of all parts. Therefore, total study style construction should be advocated. According to the principle of hierarchy for the system, we also need to attach importance to the personality development of students while emphasizing comprehensive quality of all-round development.
