The setting sun is infinitely beautiful and buried by the coming night.

Whole poem:
In the evening, I was unhappy and drove to Gu.
Sunset, infinitely beautiful, only near dusk.
In the evening, the poet boarded the Chang 'an Le Garden Scenic Area gloomily, only to see a red sun set in the west, which looked infinitely beautiful, and he could not help chanting: The sunset in the west is infinitely beautiful, but beautiful, and it is near dusk.
