Literally, her body (referring to her ex-wife Tang Wan ~) has been buried underground for a long time, and it may have turned into loess under the grave, but a song she sang with me < Hairpin phoenix > Tang Wan's ink is still on the wall of Shenyuan Garden, and the main technique used in this couplet poem is contrast. The contrast between "Jiu" and "Jude" is the contrast between the past and the present, which shows that although died for a long time, the ink is still there, hiding the author's sentimental feelings of seeing things and thinking about people. In addition, a technique of duality is used, in which "jade bone" treats "ink mark" and "soil under the spring" treats "dust between walls", making the poem neat and catchy, and implicitly expressing his thoughts and memories of Tang Wan.
