Lü Shuangbo is an author about whom limited public information is available; the library currently holds only one work by this name, The Complete Book of Toast Speeches (Zhu Jiu Ci Da Quan). Judging from its subject, the author focuses on a specific and practical area of Chinese food culture and social etiquette: toast speeches. A toast is at once an oral expression at the banquet table and a cultural form in social exchanges, covering festivals, weddings, business occasions, family dinners and more. It is therefore reasonable to infer that the author emphasizes practicality and real-life situations, organizing toasts for different occasions so that readers can consult and adapt them with ease. Books of this kind are usually written in plain language with clear entries, combining the features of a reference work and a book on folk customs. Since information about the author's life and nationality is not recorded in the library, a full picture of the author's work cannot yet be drawn, but on the strength of the existing title, Lü Shuangbo offers general readers an accessible introduction to how toast speeches are written and used.
