Brief introduction of Shangshu:
Shangshu is a compilation of works about ancient deeds, the earliest title of which was Book. It is divided into Yu Shu, Xia Shu, Shangshu and Zhou Shu. Because it is one of the five Confucian classics, it is also called the Book of Songs. The popular versions of Notes to Thirteen Classics and Shangshu are the co-edited versions of Jinwen Shangshu and pseudo-ancient prose Shangshu. In the existing version, the authenticity is mixed.
Shangshu is the oldest collection of royal works in China, the first ancient historical document in China, and a compilation of some works describing ancient deeds. Some important historical materials of Shang and Zhou Dynasties, especially the early Western Zhou Dynasty, have been preserved. According to legend, Shangshu was compiled by Confucius, but some titles were later added by Confucianism as ancient prose. At the beginning of the Western Han Dynasty, there were 29 articles, which were copied in the popular official script of the Han Dynasty, and were called Jinwen Shangshu.
According to legend, the history of ancient literature found in the wall of Confucius' mansion during the period of Emperor Wu of the Han Dynasty (there are few lost articles, more than the history of modern prose 16) and the history of pseudo-ancient literature proposed by Hu Mei in the Eastern Jin Dynasty (25 more than the history of modern prose). The popular versions of Notes to Thirteen Classics and Shangshu are the co-edited versions of Jinwen Shangshu and pseudo-ancient prose Shangshu.
As far as literature is concerned, Shangshu is the symbol of the formation of China's ancient prose. According to Zuozhuan and other books, before Shangshu, there were three graves, five classics, eight categories and nine hills, but none of these books were handed down.
