In terms of content, in chronological order, from "young son's Oedipus" to "juvenile lovesickness", to "the turn of life and death" in adulthood, and then to the feelings for the motherland and the mainland, the growing feelings gradually rose, which condensed the poet's life vicissitudes from childhood to old age.
Nostalgia is at different stages, and the two ends of the connection are: I-mother; I-the bride; I (life)-mother (death); I (a wanderer)-the mainland (the motherland). The object of homesickness ranges from concrete "hometown" to abstract national "hometown", from regional hometown to historical hometown and cultural hometown. Make "homesickness" gradually precipitate rich connotation and expressive force.

homesickness
Author: Yu Guangzhong (Modern)
In childhood
Homesickness is a small stamp.
I'm at this end
Mom is over there.
When I grow up
Homesickness is a narrow ticket.
I'm at this end
The bride is over there.
We'll talk about it later.
Homesickness is a low grave.
I am outside
Mom's inside.
But now
Homesickness is a shallow strait.
I'm at this end
The mainland is over there
