Revised first edition, Showa 52 (1977) There are no noticeable scratches or writing. As it is an old book, there is age-related deterioration. I will sell it to someone who understands that it is an old book. This is a recommended book that Soichiro Takato mentioned. Title: Introduction to Chinese Taoist Sexual Arts: The Secret Method of Pleasure and Longevity Author: Qin Haoren Taka Shobo Thank you for looking.
