Abstract: Though vocabulary “can best tell the features of its times”, it is very challenging to conclude that the preface/annotation of Jiu Si was made in the Six Dynasties, just according to the fact some words within “could not be available in the Western and Eastern Han Dynasties”. Even if it is true, it is true partially to some few documents extant, not all of them at that time. The same happens to Jiu Si, generally recognized as Wang Yi’s work. The example of “Zhang Ju first, followed by Shi Ci” is cited not only in Ji Si Zhu, but also in Yuan You Zhu, a fact telling seemingly an inconsistency with the annotation style of Zhang Ju. But it is just one exception in fact. Someone’s claim that Jiu Si Xu was not complied by Wang Yi, seems to be groundless. Various proofs that the preface/annotation of Jiu Si was made in the Six Dynasties can never shake the truth that Wang Yi is the true compiler.

Key words: Chu ci Zhang Ju, preface/annotation of Jiu Si, Wang Yi’s compiling, common words of Six Dynasties
