What does it mean to be late in the day? What does it mean to be late in the day?

In Du Fu's two quatrains, the phrase "late sunrise and beautiful scenery" means to describe the evening scenery, and "late sunrise" is a word often used to describe the evening time in ancient poetry, which means the moment when the sun sets, that is, at dusk. In this sentence, the whole sentence means "the mountains and rivers are very beautiful in the evening"

The ancients felt about life from the beauty of the scenery. This sentence expresses the philosophical thinking of "Time makes people old and cherishes time" and the emotional attitude of praising the beautiful scenery in the years. The whole poem is about the poet lamenting the ruthlessness of time and the tragic life after witnessing the decline of the general trend, the replacement of power and the shortness of life.
