About what? Three graves and five yards? The earliest record is in the twelfth year of Zuo Gong: Wang Yue:? This is a good history, and my son is good at it. I can read three graves, five classics and eight categories, jiusan. The eight categories and nine hills mentioned in this book are also ancient books, which are juxtaposed with the Three Graves and Five Classics, and these two books have not been passed down to later generations.
Different scholars in different times have different interpretations of the two books, Sanzu Tomb and Five Classics. Kong Anguo, the grandson of Confucius X, a great scholar in the Han Dynasty, once said in Preface to Shangshu? Three graves and five yards? The content of:? The book of Fuxi, Shennong and Huangdi, called "Three Graves", is also a road; Zhuan Xu, Tang and Yu Zhishu called it the Five Classics, and what they said was what they often said? Kong Anguo believed that the "Three Graves" were actually Huang San, which recorded the deeds of Huang San. The Five Classics are the Five Emperors. Record their deeds.
In the Eastern Han Dynasty, Zhang Heng thought that the "Three Tombs" had nothing to do with Huang San. He believes that the so-called three graves are actually three rituals, because it is recorded in Erya. Grave, big defense also. ? Great defense means ceremony, so Zhang Heng thinks that "Three Graves" records the three ceremonies between heaven and earth. Ma Rong, another famous Confucian scholar in the Eastern Han Dynasty, gave a completely different explanation. He thinks that the three graves are the three gases of heaven and earth. What is described in the Five Classics is about the Five Elements.
It can be seen that each family just talks about their own understanding, and there is no substantive evidence. Therefore, Du Yu, a scholar in the Jin Dynasty, disagreed with the previous explanation and only thought that these books were ancient books and did not explore the content.
