However, since the water is still flowing, although we cut it with the sword, we return with sorrow and joy, but we drown it with wine. This bold language and harmonious melody is the most wonderful sentence in the poem, which profoundly shows the irreconcilable contradiction between the poet's ideal and reality, and is also a famous sentence describing melancholy for thousands of years. I hope to be free from water, but the past days are like running water and I can't get rid of them. Therefore, the poet can only raise a glass to dispel his worries and cannot extricate himself from the growing worries. It best describes the poet's depression, anger and confusion at that time.
