As an integral part of my country's higher education, the self-study examination's responsibility is to advocate self-study, encourage self-study, help self-study, promote self-study at the level of higher education, and pave the way for every self-study to become a talent. Organizing and writing teaching materials for readers to learn is an important part of fulfilling this responsibility. There is no doubt that this kind of teaching materials should be suitable for self-study and should help learners master and understand new knowledge and new information; help learners enhance their awareness of innovation, cultivate practical abilities, and form self-study capabilities; and should also help learners apply what they have learned and solve problems encountered in practical work. Although we continue to use the concept of "teaching material" for a book with such characteristics, it is quite different in terms of content arrangement, writing style, and writing style compared with the kind of textbook that is only for teachers to teach and students to listen, but teachers do not teach and students do not understand, and are centered on "teaching." I hope readers will understand this so that they can establish a firm belief in learning on their own from the beginning. Constantly explore learning methods that suit you, make full use of your existing knowledge base and practical work experience, and maximize your own learning methods and potential to achieve your learning goals.
