What classics reflect the spirit of three rites from different aspects?

Zhou Li, Yi Li, and Li Ji are the classic works that formulated the etiquette system in ancient times. Zhou Li, also known as Zhou Guan, is the first of the three ceremonies. It was first published in the Han Dynasty, and was changed to Zhou Guan Jing because it was mixed with Shangguan Pian. At the end of the Western Han Dynasty, it was listed as a sacred code, belonging to the ritual code, hence the name "Zhou Li". This book collects the official systems and systems of the Zhou Dynasty and the vassal states, and compiles them with Confucian political ideals. Zhou Li is divided into six chapters, including Tianguan Zhuzai, Emperor Guan Situ, Chun Guan Zongbo, Xia Guan Sima, Qiu Guan Si Kou and Winter Litigation Empty. Among them, the article "Dongguan" has long been lost, and it was supplemented by "exam notes" in the Western Han Dynasty, which was called "Dongguan exam notes". This book is divided into forty-two volumes. Book of Rites, also known as Book of Rites or Book of Rites, is one of the Five Classics in Pre-Qin Dynasty. It was originally called "Li" directly. The book was roughly formed in the late Spring and Autumn Period, and some people think it was compiled by Confucius. Confucius did regard propriety as a practical link in teaching. The content of the book "Yili" is mainly about the details of ceremonies such as coronation, fainting, mourning, sacrifice, pilgrimage, engagement and banquet. This paper expounds the etiquette of the literati class in the Spring and Autumn Period and the Warring States Period, and advocates an equal ethical etiquette. Among them, the etiquette we can see today embodies the most detailed and clear principle of "kissing and respecting relatives", which not only reflects the social system and blood relationship at that time. After reading it, we can learn about the red tape of feudal nobles, the daily life of ancient palaces, ships, costumes, food and so on, as well as religious beliefs, kinship system, political organizations, diplomatic methods and so on. The content of The Book of Rites is mainly to record and discuss the pre-Qin ritual system and significance, explain the Book of Rites, record the questions and answers between Confucius and his disciples, and describe the principles of self-cultivation. In fact, this 90,000-word book has a wide range of contents and diverse categories, involving politics, law, morality, philosophy, history, sacrifice, literature and art, daily life, calendar, geography and many other aspects. It is almost all-encompassing and embodies the political, philosophical and ethical thoughts of Confucianism in the pre-Qin period. It is an important material for studying the pre-Qin society.
