It started in the year of Luyin and ended in the 14th year of Lu Aigong, which is the same as the beginning and ending time of Chunqiu. Its author is a disciple of Shang Bo. During the Warring States Period, Qi people were all men and tall.
At first it was just word of mouth. When Emperor Jing of the Western Han Dynasty was in power, it spread to Xuansunshou. Shou and Hu Musheng wrote the bamboo and silk Biography of the Spring and Autumn Ram together. Biography of the Ram includes Biography of the Ram in the Spring and Autumn Period by He Xiu in the Eastern Han Dynasty, Biography of the Ram by Yan Xu in the Tang Dynasty and Biography of the Ram by Chen Li in the Qing Dynasty.
Historical value:
First, The Biography of the Ram thinks that Confucius runs through the political "righteousness" such as "unification" and "bringing order out of chaos" in the Spring and Autumn Annals. As the most important principle of Confucianism, Confucius' position of supporting Zhou Tianzi as the "master of the world" was vigorously promoted to prepare for the ongoing "reunification" at the end of the Warring States period. It even directly became the governing program formulated by Confucius for Emperor Wu of the Han Dynasty!
Secondly, The Biography of the Ram also contains the viewpoint of historical changes, from which people can infer and divide the historical development stages. This is the famous saying of Ram III. More importantly, his explanation of the theory of three generations of different words contains a valuable point: Chunqiu 242 is not regarded as monolithic and unchangeable, but can be divided into different development stages according to certain standards.
