The introduction is a general introduction to a wide range of disciplines, generally there will be no in-depth analysis, but there is a concise introduction to history and the future, so that readers can have a general understanding of this discipline. Some professional introductions are relatively comprehensive and simple, which lays the foundation for subsequent courses.
For example, in the first year of a university, an introductory course involving majors is offered to let students have a little professional knowledge so as to better understand the purpose of learning existing courses. In short, the role of "introduction" has changed from simply introducing an article or a book to introducing a subject and major with a book.
Introduction can be divided into humanities and social science articles and natural science articles according to disciplines, and can also be divided into law introduction, gene introduction and literature introduction. Among them, the introduction to law is the most widely used, which refers to the basic overview of departmental law.
