What ancient poems reflect the life and customs of the ancients?

In ancient times, poetry and music were closely related, and many poems reflected the life and customs of the ancients from different angles. For example, the Book of Changes (June 4th) recorded a custom of robbing marriage at that time, that is, "the original is like, the easy is like, and the white horse is like; Bandits, hey. " The main idea is that the man riding a beautifully dressed white horse is not a thief, but a man who is going to get married. There are also contents that reflect the war, such as the Book of Changes. Floating in the middle (63): "Win the enemy, or drum, or stop (sound), or cry, or sing." The general idea is: because of defeating and capturing the enemy, some people beat gongs and drums, some people beat gongs and drums, some people cried and sang happily, and so on.
