I always think this is a poem that can best express homesickness.
And Li Yu also said that I don't know if I am a dream guest. In Nineteen Ancient Poems, life between heaven and earth suddenly looks like a passer-by. Have the same effect.
There is another sentence in Xi Murong's poem, which is quite heavy. She said: If you meet a place where everyone lives together, consider it your hometown.
Because I can't go back to my hometown, or I have been away for too long, I have forgotten what my hometown is like. No matter where I am, I will always be a guest, so I can only find one place as my hometown.
I hope I can help you.
