Poetic significance of Bai Pu's bosom friend

It's about Bai Pu's Sanqu [Lv Zhong] Yang Chunqu. Know a few things, as follows:

Knowing honor and shame means keeping your mouth shut, and who is who is not nodding. I stayed between poems and books for a long time. Idle hands, poor evil spirit also romantic.

It's not because of wine and poetry. I'm often haunted by dreams. At four o'clock, the wind and moon are idle. Useless people, poetry and wine are all happy.

Quit Han's whole body and go back to the lake to harm the machine. Le Shan Le Shui is always suitable. If you push it carefully, how many people knew it in ancient times.

This Sanqu is about "knowing a few things", that is, knowing the subtle signs of things' changes will harm the whole body.

Among them, "knowing honor and shame is a secret, and who is who is not nodding" reflects the social reality of political darkness and intellectuals' voices in Yuan Dynasty from one side. "Not because of wine and poetry, I often indulge in reciting" depicts an intellectual image who loves drinking, writing poetry and indulging in bitterness. "Useless people, poetry and wine are free and true" embodies the integrity of intellectuals who can't exert their strength politically, so they are free in poetry and wine. The allusion of "quitting the whole body of Korea and returning to the lake will harm the machine far away" leads to the theme of "knowing a few things" The conclusion "How many people knew each other in ancient times" has profound implications, including profound reflection on history and sober understanding of reality.
