What kind of feelings does homesickness express?

This poem uses "stamp" to express the memory of mother, and "grave" to express the memory of mother, which is a kind of deep affection; It is a kind of warm love to express my thoughts on my new wife with a "boat ticket"; The Straits expresses the poet's nostalgia for his hometown and motherland.

This is a deep patriotic feeling. These groups of images constitute the rich connotation of homesickness and make it more obvious. Feelings are getting stronger and stronger, and the theme is getting deeper and deeper.

It is with this structural form that the author, like the repetition of the main theme in music, repeats the pain of separation in one chant and three sighs, vividly rendering homesickness. So critics say this poem is extremely beautiful in structure and music.
