This is an academic work on the management of history. The author wrote it at the request of many scholars, especially young students. The main body of the book is the methodology of historical studies. But the views and methods described are not merely didactic. Just like the author's previous works, the style of writing is simple and sincere, with the combination of lively and vivid theory and examples, narratives and discussions, which makes people both relaxed and deeply inspired. The book's insights on the basics of learning, problem awareness, and how to write biographies will be a profound guide for those who want to devote themselves to academics.
