Book of Documents

The Book of Documents (Shujing, earlier Shu-king) or Classic of History, also known as the Shangshu, is one of the Five Classics of ancient Chinese literature. It is a collection of rhetorical prose attributed to figures of ancient China, and served as the foundation of Chinese political philosophy for over 2,000 years.

The Book of Documents was the subject of one of China's oldest literary controversies, between proponents of different versions of the text. The "New Text" version was preserved from Qin Shi Huang's burning of books and burying of scholars by scholar Fu Sheng. The longer "Old Text" version was supposedly discovered in the wall of Confucius' family estate in Qufu by his descendant Kong Anguo in the late 2nd century BC, lost at the end of the Han dynasty and rediscovered in the 4th century AD. Over time, the "Old Text" version of the Documents became more widely accepted, until it was established as the imperially sanctioned edition during the early Tang dynasty. This continued until the late 17th century, when the Qing dynasty scholar Yan Ruoqu demonstrated that the additional "Old Text" chapters not contained in the "New Text" version were actually fabrications "reconstructed" in the 3rd or 4th centuries AD.
