Ruth Benedict’s The Chrysanthemum and the Sword is one of the representative works of “theories about Japanese” research in the world. This article newly discovered the Chinese book review of Chrysanthemum and the Sword published in the Chinese Press Review sponsored by the United States Information Service on January 4，1947，which changed the fixed views of the academic circle in this field. On the basis of introducing the content and publication background of this book review，the article also works on the research on “theories about Japanese” in China before and after the Counter-Japanese War to explain the issue that although Chineses had already noticed the publication of Chrysanthemum and the Sword，an important work on Japanese studies，the book has not received sufficient attention nor been translated，which can contibute to the understanding of the conditions that a new Japanese research theory can be accepted，such as the need for the research subject to eliminate emotional factors towards the research object as much as possible，and to answer the core questions that the audience is concerned about. New theories need to have stronger explanatory power and obtain innovative conclusions that have not been explained by previous scholars；New theories attach great importance to the advantages and disadvantages of research methods and improve the professionalism of our research continuously.
