I felt unwell at night and drove to Guyuan. The sunset was infinitely beautiful but it was almost dusk. What does it mean?

Translation:

As evening approached, I felt a little uncomfortable;

Driving to Leyouyuan, I wanted to get rid of my worries.

Seeing the sunset is infinitely beautiful, with a brilliant golden light;

It is just about dusk, and the beautiful time is short after all.

Today in the evening, I felt a little uncomfortable, so I got on the carriage and went to the ancient Leyouyuan. At this time, I saw the sun that was about to set. It was really beautiful. Unfortunately, it was almost dusk and it would disappear soon.
