This study examines the situation in Textual Criticism and Exegetics of Guwen Shuangshu in the medium term of Qing Dynasty after the staged achievements in the work of distinguishing the ancient pseudo-text. We will focus on the research from three trend: restoring the Ancient Shangshu, the revaluation about Shangshu Kong Zhuan, the editing of Shisanjing Zhu Shu and Jin Dian Ski Wen. According to the research trends at that time, there were group discussions on three topics: “The problem of using characters”, “Biographical research of Shangshu Kong Zhuan”, “Zheng Yi and Ski Wen”, to analyzes their research in the contribution or influence in the history of Shangshu.
In “The problem of using characters”, we analyze Jiang Sheng’s “Shangshu Ji Zhu Yin Shu”, Wang Mingsheng’s “Shangshu Hou An”, Duan Yucai’s “Guwen Shangshu Zhuan Yi”, and Sun Xingyan’s “Shangshu Jin Gu Wen Zhu Shu”, to observe their revision of the text, the way of using "Shuo Wen Jie Zi" to editing. Compare their collation work in using characters of Shangshu, we find that their revision did not consolidate it into a normal form only, but a form that could correctly reflect the meaning of the scriptures.
In “Biographical research of Shangshu Kong Zhuan”, although that "Shangshu Kong Zhuan" has been affirmed by scholars in the past. But at the same time, the work of reviewing the interpretation of "Shangshu Kong Zhuan" has already begun among Sinology scholars in the medium term of the Qing Dynasty. Duan Yucai’s "Ancient Chinese Classics", Gaoyou Wang's "Jing Yi Shu Wen", and Jiao Xun's "Shangshu Shang Bu Shu", they have mastered the explanatory principles of "Kong Zhuan" that values "orthodox training" and "literally training", therefore, they can actively review the Misinterpretation from "Kong Zhuan", and pointed out that this book appeared in the Wei and Jin Dynasties, and its academic significance as the aftermath of Sinology.
In addition, the atmosphere of specializing in "Shangshu Zheng Yi" in the mid-Qing Dynasty was relatively weak, and the review and collation accompanying the commentaries on the classics were the most important research results of " Zheng Yi " in this period. Because of this, our research is based on the records of the four kinds of collating note in the medium term of the Qing Dynasty, including " Shangshu Zhu Shu Kao Zheng ", “Shisanjing Zhu Shu Zheng Zi”, “Qun Shu Shi Bu” and “Shisanjing Zhu Shu Jiao Kan Ji”. We believe that, these notes are not proofreading, but also with the content of "Zheng Yi "proposed to distinguish the layers of ancient books, presumably traces of the ancient appearance of the ancient scriptures. Although the related research still has deficiencies, but it proved that there was a relatively "conservative" research atmosphere outside of "the Qing Dynasty Sinology".
Through three topics, this study puts forward two conclusions. First, although there is a new trend in the study of Shangshu in the middle term of the Qing Dynasty under the trend of "Sinology", the content is actually based on "The text of Shangshu be annotated by Kong Anguo". Secondly, judging from the theory of collation or exegesis, although collation and exegesis were widely used as research methods at the time, judgments on specific issues were mostly based on external authority, rather than internal theory or literature. Objectively presented as a criterion of judgment.
