The Spring and Autumn Annals is divided into five parts, The Poetry is divided into four parts, and The Book of Changes has been handed down by several families. During the Warring States period, there was a dispute between authenticity and falsehood, and the words of various philosophers were confused. In the Qin dynasty, it was the governors who ruined the text and made fun of it. Han Xing changed the defeat of the Qin Dynasty, collected a large number of books, and opened up the road of offering books. At the time of filial piety, books lack simplicity, and rituals collapse and music breaks down. The saint sighed in shame: "I'm very sorry!" " Therefore, the strategy of building Tibet, the officials who wrote books, and the legends of various factions are all filled with secret rooms. By the time he became emperor, the books were quite scattered, which made the worshiper Chen Nong ask for a suicide note on earth.
Under the background of "the dispute between authenticity and falsehood", "the subjugation of articles", "collecting a large number of articles, broadening the ways of giving books", "keeping the legends of various philosophers secret" and "asking for a suicide note", the circulation, creation and arrangement of books will be affected, resulting in some abnormal phenomena, which need to be carefully identified. Mr. Wang Baoxian pointed out that when the Han Dynasty became emperor, the number of articles increased greatly and there were many books. "Liu Xiang relies on himself as a famous scholar, a well-known scholar in one's hand and one's hand, and belongs to Liu Zongshi. With the opportunity of sorting out the royal library and the convenience of being close to Emperor Yuan, it is natural for him to form his own system in sorting out important classics to compete with other schools of Confucian classics. The number of articles and articles he drafted are different from the old ones, and even the title of the book has to be redrafted. "
Xiong Tieji said in "Detailed Explanation of Liu Xiang's Collating Books": The chapters, characters and even some titles of the ancient books before the Western Han Dynasty that we saw today were all revised by Liu Xiang. At that time, almost all the books were understood, recognized and even transformed by them, and of course they were inevitably branded with the times. However, this point has not been fully recognized for a long time, thinking that the ancient books of pre-Qin read by future generations and even today are original works, which will inevitably lead to misunderstandings and conclusions that are inconsistent with the historical truth. Many scholars in the past dynasties found some problems, which caused doubts and disputes, so there were works referring to falsehood. Judging from the existing book records and related records, some books are completely new. For example, Liezi Shu Lu ... It can be seen that Liu Xiang has completely compiled a new book Liezi. A hundred schools of thought contend is regarded as the orthodox origin of China culture. At that time, Liu Xiang sorted out the scattered fragments of endangered philosophers. Although there are no ten ancient books of these philosophers, Liu Xiang has made great contributions to sorting out the ancient books of pre-Qin philosophers.
