Why is Li Bai sad that ancient poems will be drunk?

This poem was written by Li Bai after his return to Chang 'an, with profound ideological content and mature artistic expression. Poetry originated in the Yellow River, and its emotional development is as turbulent as the water of the Yellow River, which is difficult to grasp. The whole article talks about drinking. Literally, the poet is advocating binge drinking. The poem uses a positive appreciation attitude and heroic momentum to write about drinking, which is magnificent and does have some negative effects, but it reflects that the poet could not find an effective weapon against the dark forces at that time. Wine is a stimulant for his personal resistance. With wine, it seems that he has the strength of hordes, but wine is also his mental anesthetic, which makes him unable to actively resist in indulgence, which shows the limitations of the times and classes. The disillusionment of the ideal is caused by the dark society, and the poet is powerless to change it, so he turns the rising anger into a bold act of enjoyment, vents his dissatisfaction, dispels his worries and resists reality. This poem expresses the author's lament about his lack of talent, optimism and understanding, and also reveals the negative emotion that life should be carpe diem. The whole poem is full of lofty sentiments, magnificent momentum and outstanding artistic achievements.
