Bamboo slips were discovered earlier and have been around since the last years of Emperor Wu of the Han Dynasty. This is known from ancient documents. According to records in "Hanshu Yiwenzhi" and other books, in the last years of Emperor Wu, King Lu of Lu broke into Kong's house and obtained a batch of ancient bamboo slips. This kind of writing was no longer recognized by people at that time. Later, after Kong Anguo's appraisal, it was found that the contents contained dozens of classics such as "Shangshu" and "Book of Rites". But among them, "Shang Shu" was soon lost. In the Eastern Jin Dynasty, a man named Mei Yun presented it, and it was said that it was accompanied by a biography written by Kong Anguo. However, after subsequent research, it has been concluded that the ancient part of the book (that is, the interpretation based on the bamboo slips) and the biography of Confucius are forgeries, and it is now concluded that this is the largest bamboo slip forgery incident known to date.
