Kong Jifen (1725—1786), the 69^th-generation grandson of Confucius, was one of the most famous Confucian classics historians of Confucius family in Qufu of the Qing Dynasty, who had played an important role in the academic history of Confucius family. With fruitful achievements in a wide range of academic fields, Kong Jifen completed at least 16 academic works, among which Que Li Bibliography and Rites and Rituals of Confucius Family are the most important ones. The former is focused on the history of Confucian family and the latter is concentrated on the etiquettes of Confucian family. In general, despite Kong Jifen’s high academic achievements, they have not been paid enough attention by the academic circle for a long time. Previous researches have clarified some problems, such as his life story, official career, writings, literary inquisition, academic value and so on. However, there are also many shortcomings in the existing studies, such as the lack of systematic arrangement and research of his works, the absence of many remaining works that have not yet been checked, compiled or published, the lack of comparative studies with contemporary scholars, the lack of a comprehensive evaluation of his life and academic achievements, and the need for in-depth exploration and utilization of new historical materials such as the archives of Confucius family.
