(2) This poem expresses the poet's noble feelings of unwilling to go along with the eunuch. In a word or two, the poet lives in seclusion at home and likes to walk on a moonlit night. The elegance of this moonlit night shows the clarity of the poet's mind after he left the officialdom. The last four sentences are written because no one enjoys the beauty of the night with him. I think of Tao Yuanming thousands of years ago, and the poet euphemistically expresses his feelings with this hard-to-find homesickness. (If you have other understandings, you can give points as long as it conforms to the poem. )
