There were many poems and essays about homesickness. Among them, the more famous ones were Wang Zhihuan's "Climbing the Stork Tower" and Su Shi's "Jiangcheng Zi·Dream on the 20th Night of the First Month of Yimao": "Climbing the Stork Tower": The white sun is leaning against the mountains, and the Yellow River flows into the sea current. I want to see a thousand miles and climb another level. This poem expressed the poet's desire to pursue a higher realm and homesickness by describing the magnificent scene of the Yellow River entering the sea. [Jiangcheng Zi·Dream Record on the 20th Night of the First Month of Yimao]: Ten years of life and death, both boundless, not even thinking about it, is unforgettable. A lonely grave thousands of miles away, I have no place to talk about desolation. Even if we meet again, we should not know dust, face and hair like frost. In the dark night I dreamed that I had suddenly returned to my hometown, and was dressing by the window of my cottage. We look at each other without saying a word, only a thousand lines of tears. I expect my heart to be broken year after year, where the bright moon is short on the pine hill at night. This poem expressed the poet's homesickness and thoughts about life by describing the scene of the poet's dream of returning to his hometown. Through the memories in the dream, the poet expressed his longing for his hometown, and at the same time, he had a deeper understanding of the impermanence and changes of life.
