How about Xu's Guiguzi?

Not bad. Xu's Guiguzi pays attention to political strategy and has a unique speculative style. Whether it is "strange" reflects the characteristics of the era when the sky is falling and the princes are fighting for hegemony during the Warring States period. Guiguzi was a representative figure of a hundred schools of thought contending during the Warring States Period. Professor Xu is an expert on guiguzi. His doctoral thesis "Research on Guiguzi" proves that this edition of Guiguzi is an ancient book in the pre-Qin period from the phonological point of view, which solves the problem that the academic circles have always regarded this book as a fake book since the Tang Dynasty, and lays an academic foundation for people to study and use Guiguzi widely today. His book Guiguzi Collection, collation and annotation of ancient books collected all versions of Guiguzi, and carefully sorted and annotated them, which solved the problem of lack of authoritative texts in the research field of Guiguzi for a long time.
