Throughout the writing and editing of this book, we have both enjoyed the advantage of certain comprehension basis, and a certain degree of difficulty, certain comprehension basis as an advantage, firstly because we had already edited the "Introduction to Deng Xiaoping Theory", "Introduction to the Important Thought of Three Represents", since their publication in 2003, the titles were re-published for dozens of times, and the aggregate print of them has nearly reached 3 million, most of which have reached the readers. Secondly, the writers of this textbook are all in the front line of teaching and research, they have a certain degree of research accretion on the theoretical system of socialism with Chinese characteristics and have abundant teaching experience on the subject. Thirdly, the academic community has made abundant research on "Deng Xiaoping Theory", and on the "Important Thought of Three Represents" and also on "The Scientific Concept of Development" and other major strategic thoughts, which are component parts of the theoretical system of socialism with Chinese characteristics, and have produced numerous precious research results. These above favorable conditions have laid a virtuous foundation in the writing and editing of this book.
We have faced certain degree of difficulty, firstly because the theoretical system of socialism with Chinese characteristics still encounters enrichment and perfection. The academic circles have different understandings of its theme, its historical starting point, main content and the logical structure of this theoretical system. There still exist differences in the understanding and interpretation of many major issues regarding it. Secondly, we have encountered a considerable difficulties, as in the following, how to break through the previous framework of Deng Xiaoping Theory and unify the three strategic thoughts of--Deng Xiaoping Theory, Important Thought of Three Represents, and The Scientific Concept of Development--and integrate them into one and same book, because all the three not only represent major theoretical achievements having their own unique characteristics, but also have succession and development relations among them, besides they follow the same strain and have included successive times characteristics.
