Li Gang is an author about whom little public information is available; the library currently holds only one work by this name, namely Three Books on Japan. Judging from the title and its usual classification, the book falls under culture and is likely to deal with Japanese culture, perhaps offering an organized introduction to aspects of Japanese society, thought, or cultural phenomena. Since details such as dates of birth and death, nationality, educational background, and writing career cannot be confirmed, little more can be said about the author's life. On the basis of the available material, Li Gang's writing leans toward cultural subjects and is presented in the form of "three books," suggesting a certain systematic structure that may be useful to readers interested in Japanese culture. Although the number of works is small, the subject matter is focused, indicating the author's attention to and accumulated knowledge of a particular cultural field. Readers who wish to learn more about Li Gang can for now rely only on this single work, and further information remains to be added.
