This poem is divided into four sections, describing the writer's different feelings about "homesickness" from childhood to adulthood. The first section was written when I was a child. Because the author has separated from his mother, the homesickness he felt at that time was actually a deep miss for his mother. This kind of sadness can only be relieved by fish and geese exchanging messages back and forth, but the author did not show it directly, but implicitly expressed his affection with a "small stamp".
The second section is about a person's homesickness when he grows up, leaving his hometown to study in a foreign country for his own future and studies. The author and his wife just got married, but they had to separate. At this time, homesickness is missing your partner. Holding a "narrow boat ticket", it was the author's greatest wish at that time to go back to China by boat to see his family.
Time passed again, and in the third season, the author wrote that after losing his mother, heaven and man were separated forever. This "homesickness" is not a matter of distance, and his feelings for his mother can only be remembered forever. Finally, after experiencing the ups and downs of life, the author can't help but have a strong yearning for his hometown Chinese mainland. However, due to the limitation of political reality, even a "shallow strait" cannot be easily crossed.
This poem is one of the author's masterpieces, and it has been widely read. Although the emotion expressed in the last paragraph is based on the author's special life experience, readers can also substitute their own experiences and still get the voice and experience of * * *.
