In the Tang Dynasty, Li Longji, Emperor Xuanzong of the Tang Dynasty, merged the two ancient prose schools, personally annotated the Book of Filial Piety, ordered Yuan Xing to make it sparse, and promulgated the world. Zheng Hekong's notes gradually died out. In the Song Dynasty, Xing Bing refined Yuan Xing Chong, which became the final version of the annotation of Thirteen Classics. This collating is based on Taiding edition of Ming Dynasty, and the collating results of Ruan Yuan in Qing Dynasty were absorbed by the participants, and the collating and punctuation were re-conducted. At the end of the book, there is a preface and postscript summary for readers to study. Mr. Jin Liangnian, the organizer, has studied annotation for many years and accumulated a lot of experience. He is an expert in this field.
