Shangshu is listed as one of the important core Confucian classics, and "Shang" means "Shang". Shangshu is an ancient book. It is a compilation of ancient historical documents of China and some works tracing back ancient deeds, and it is the earliest compilation of historical documents in China.
The earliest title of Shangshu was Shu, which was written in the first five centuries. The traditional Shangshu (also known as Jinwen Shangshu) was handed down by Fu Sheng. Legend is left over from the "Three Graves and Five Codes" of ancient culture.
Twenty-eight pieces of Shangshu dictated by Fu Sheng, a scholar in the Western Han Dynasty, are modern versions of Shangshu. When King Lu Gong demolished a section of the wall of Confucius' former residence, he found another piece of Shangshu, which is an ancient version of Shangshu. In the battle of Yongjia in the Western Jin Dynasty, the modern and ancient versions of Shangshu were all lost. At the beginning of the Eastern Jin Dynasty, Shi Meihuan of Zhang Yu presented a history book to the court, including 33 modern literature histories and 25 ancient literature pseudographs.
