While historical materials of classical fictions were not systematically documented as historical science, some researchers had already organized, edited, selected and analyzed the importance of Chinese fictions in their works, such as "Xiao Shuo Jiu Wen Chao" by Lu Xun, "An Annotated Bibliography of Chinese Popular Fiction" by Sun Kaidi, "The Historical Material of Chinese Fictions" by Kong Lingjing; therefore the amount of historical materials of Chinese fictions is also considerable. How can we perform more researches regarding "Historical Materials of Classical Fictions" besides their previous works? In my opinion, we can start from reviewing the authors and titles of these works, proofreading each versions, checking public and private categories, citing books of the same category, and using study results from contemporary researchers to organize and understand these materials, in an attempt to make historical materials being able to proof the results of studies to be correct. We take "Yixian Zhuan" in "Chen, Mel Kong Family Secrets Serials Ⅱ" collected in "B 'ou Yen Tang Secrets" by Chen Ji-Ru in Ming Dynasty as an example for studying classical fictions, and the version was the very first literature ever been published in the book series. The main issue in this study is to focusing this demon and legend fiction, "Yixian Zhuan" written by Yinfu Yujian in Wu Dai period, while which was not published on any book series or single book in Ming Dynasty, I would like to comment on it through other historical materials to determine whether "Yixian Zhuan" in "Chen, Mel Kong Family Secrets Serials II" is worth the value for researchers to cite and study or not. Through the focus on the extended proofs, such as the authors, titles, table of contents and versions, I have attempted to conduct this historical research on "Yixian Zhuan" with intense researching, in a hope to objectively present the values and flaws of "Yixian Zhuan" in "Chen, Mel Kong Family Secrets Serials II" by Chen Ji-Ru in Ming Dynasty, and through which to help readers to understand the importance of studies for historical materials of Chinese fictions.
