This poem expresses the author's yearning for his hometown, which is an emotion of human beings. When you become a wanderer far away from home, wandering in a foreign land, no one will miss your hometown. The application of "homesickness", "wandering", "forgetting homesickness", "another autumn" and "dream message" runs through it, which profoundly shows the poet's deep yearning for his hometown. The Seven Laws of Homesickness creates this feeling for readers with time, victory and memories of hometown, which makes readers feel it more truly.
