What is the poem that expresses homesickness and contains the philosophy of life in "A berth under the North Fort Mountain"?

Night now gives way to the ocean of the sun, and the old year melts in freshness: (1) "Day after day" and "Spring enters the old year" both indicate the alternation of time series, and they are in such a hurry that they can't wait. How can this not make the poet in the "guest road" homesick? (alternating time series, touching the scene)

(2) These two words are extremely difficult to extract. The author regards "sun" and "spring" as symbols of new beautiful things, emphasizes the status of the subject, personifies them with words such as "life" and "ru", and endows them with human will and emotion.

The author has no intention of being reasonable, but he has a natural interest in being reasonable when describing landscapes and festivals. The sea is born in the dead of night, which will drive away the darkness; Jiang Chun will break ground at the end of the old year to drive away the severe winter. Show the universal truth of life. (Philosophically) (This is an open question, which can be started from the above three angles)
