Wu Zixu is a historical figure from the Spring and Autumn period, and military writings handed down under his name have been attributed to him. This library holds two of his works: Gailu and A Compiled Edition of Naval Warfare Art. The former deals with philosophy and the principles of governance and military affairs, while the latter focuses on compiled naval tactics, showing that the content spans the categories of philosophical reading and social science. Public information about Wu Zixu's life, native place, and dates of birth and death is limited, and the library holds no further verified details, so they are not elaborated here. Judging from the extant works, the text unfolds largely in the form of questions and answers or itemized statements, emphasizing practical strategy and tactical rules, in a style close to the pre-Qin tradition of military and political discourse. Such texts are of reference value for studying ancient military thought and naval warfare techniques, and they also provide material for understanding the writing landscape in which philosophy and practical knowledge intertwined in the pre-Qin period.
