Why does the poet compare nostalgia to stamps and boat tickets?

A stamp from his youth, a boat ticket from his youth, and even a grave in the future all embody the poet’s long-lasting thoughts of his hometown, as well as those of thousands of overseas wanderers.

The poet succinctly extracted several simple images: stamps, ship tickets, graves, and straits. These four images are simplicity, clarity, concentration, and intensity. They are also rich, that is, they are not piled up but implicit and tense, and can induce readers' many associations. These four images materialize and concretize the "nostalgia" that is originally a very abstract thing, and achieve a good artistic effect through "entrusting things to express feelings".

These images are connected with the two simple demonstrative pronouns "this" and "that", cleverly integrating people, objects, time and space that are isolated from each other, and closely integrating the two ends of melancholy. The presence or absence of distance and connection gives a strong sense of joy to those who spend their days wandering around missing each other, parting and getting together, and gives them an indescribable sadness and joy.

Poetry takes the order of time as its longitude and the distance between two places as its latitude. It has a touching charm in its flatness and straightness, arousing people's infinite sadness and endless responses. Extended information

Poetry artistically presents the beauty of organization in structure and the beauty of music in rhythm. Pursue a lively and energetic form of expression in even and neat sentence patterns, and perfectly use the rhyme of words in appropriate image combinations, so that the poems have a musical rhythm, going back and forth, singing and sighing three times. The poet used modern poetry that blended traditional Chinese aesthetic features to sing out the poet's deep attachment to his hometown and motherland.

"Nostalgia" has striking formal beauty. First, the structure incorporates changes in unity, and is balanced and symmetrical between sections and sentences. But there are also irregularities in the neatness, and the long sentences and short sentences change and stagger each other, which reflects the characteristics of free poetry. Second, the repetition of words in the same position and the use of overlapping words create a loop in the music, with a melody that is sung and sighed three times, creating a low-echo and melancholy atmosphere for the whole poem.
