Pi Xi?rui first made a simple sketch to the “Xiao Jing Zheng Zhu”and then clarified some problems in the introduction of the book such like who the author is, when the book was written and which point of view of the classics was used to accomplish the book. Although he explained them with lots of citations, we can still find the personal stance of Pi Xi?rui through them.The book “Xiao Jing Zheng Zhu” was spread before the popularity of the comment book written by the emperor Xuan which we can see today. Its deeply explanations and the comments about the ritual study and the meaning of the classics are acclaimed by lots of scholars. However, there are still some pities such as parts of the book were lost and the author of the book was unknown. They have been accomplished with the book and still have no decisions and explanations. Pi Xi?rui wrote the “Xiao Jing Zheng Zhu Shu” in order to restore the original image of the “Xiao Jing Zheng Zhu” and worked hard on the argument that the author of the “Xiao Jing Zheng Zhu” is Zheng Xuan definitely and he also used some citations to explain it. In the process of commenting, not only the textual researches, but the research of the text interpretation and the meaning of the classics can show the textual research skills of his own and the unique viewpoint of the modernliterary classics researcher. We can even find Pi Xi-rui’s high praise to Zheng Xuan and his effort of carrying forward the research of Zheng’s.In respect of the significance of academic history, the “Xiao Jing Zheng Zhu Shu” of Pi Xi?rui not only reviewed the value of “Xiao Jing Zheng Zhu” and elucidated articles and the meaning of the classics, but also praised the researches of Zheng’s and commented on the Zheng’s words.
