Although Siku Quanshu Zongmu, which officials of Qing Dynasty led by Ji Yun spent almost 25 years compiling at Qianlong’s command, is valued highly by many scholars from generation to generation, the modern studies on Zongmu highlight the issue that the authoritative Siku editors, with ingrained influence on the scholarly views of future readers, have evaluation criterion interfering with the objectivity of scholarship. The introduction and evaluation of Zongmu guide the novice readers to judging the value and nature of ancient classics and deciding whether to read or cite them. However, the forcible guidance of Zongmu makes readers passive and less suspicious. It is overdone to ask readers to follow the Chinese idiom“Better not to read at all than to believe all one reads,”but the academic researches into Zongmu, whose scholarly dominance has not been undermined yet, uncover the official stance behind what is called objective standard Zongmu bears.The authoritative discourse of Zongmu deserves not only the novice readers’ reliance but the scholars’deliberate understanding and reasonable suspicion. The dissertation aims to explore how Zongmu speaking for Qing authority evaluates and sums up the Study of the Spring and Autumn Annals in Ming Dynasty, to further analyze what evaluation criterion Zongmu holds for the classic and to disclose if there is objectivity and justice in the evaluation of Zongmu.
