"I am at this end and my mother is at that end." This is Oedipus' homesickness; "I am at this end and the bride is at that end." This is the homesickness of love; "I am outside and my mother is inside." This is homesickness for life and death; "I am at this end and the mainland is at that end." This is the homesickness of space. From childhood to adulthood, and then to the present, time is passing, and this homesickness has changed from one person's homesickness to that of a group of people and a generation. The common images such as stamps, boat tickets, graves and straits have magnified the "homesickness" in the poet's works countless times.
From hope to disappointment, from despair to despair, and then from despair to hope, the whole poem expresses homesickness incisively and vividly, and also expresses the deep expectation for the reunification of the motherland.
