Hong Xingzu, Zhu Xi and others doubted the authenticity of Lunyu bijie. The “Introduction of the Classification” of Siku quanshu said that it was not written in the Song Dynasty. It shows the complexity of this problem. This paper aims at the literature concerning Han Yu’s interpretation of the Analects of Confucius, going through the arguments from the Tang dynasty to the Qing dynasty to discuss its problems, then takes up consideration of Jiaoke Hanwengong Lunyu bijie which was transcribed by Ito Kinen from his friend Hayashi Ine’s Jiaoke Hanwengong Lunyu bijie in 1761 and published in 1771 . It answers: Who was the author of Lunyu bijie;, what is the relation between it and Han Yu’s Lunyu zhu; how many volumes it had; and why from ten volumes it has become just two volumes. Finally, this paper examines the process of the formation of Lunyu bijie to locate Ito Kinen’s Jiaoke Hanwengong Lunyu bijie.
