no reliable evidence to attribute these revisions to either Dai De or Dai Sheng, although both of them were Confucian scholars specialising in various texts concerning li. Nevertheless, at this time these texts were still being edited, with new script and old script versions circulating, and the content not yet fixed. However, when Zheng Xuan, a student of Ma Rong, composed his annotated text of the Rites he combined all of the traditions of ritual learning to create a fixed edition of the 49 books which are the standard to this day. Zheng Xuan's annotated edition of the Rites became the basis of the "Right Meaning of the Ritual Records" ( ) which was the imperially authorised text and commentary on the Rites established in 653 AD. In 1993, a copy of the "Black Robes" chapter was found in Tomb 1 of the Guodian Tombs in Jingmen, Hubei. Since the tomb was sealed around 300 BCE, the find reactivated academic arguments about the possible dating of the other Liji chapters by the Warring States period. Li Confucius described Li as all traditional forms that provided a standard of conduct. Li literally means "rites" but it can also be used to refer to "ceremonial" or "rules of conduct". The term has come to generally be associated with "good form", "decorum" or "politeness".

As outlined in the Book of Rites, li is meant to restore the significance of traditional forms by looking at the simplicity of the past. Confucius insisted that a standard of conduct that focused on traditional forms would be a way to ease the turmoil of collapsing Zhou state. The absolute power of li is displayed in the Book of Rites: "Of all things to which the people owe their lives the rites are the most important..." The ideas of li were thought to become closely associated with human nature, ethics, and social order as the population integrated li into their lives. Li is beneficial to society because it guides people to recognize and fulfill their responsibilities toward others. Legacy As a result of the Book of Rites' chapters, using a syncretic system later scholars formed both the Great Learning and the Doctrine of the Mean. These two books were both believed to be written by two of Confucius'
