What does the last couplet of the two books about the story after the snow express?

1. By means of comparison and rendering, the whole poem hardly involves the color and fragrance of plum blossoms, but pays attention to the comparison of the environment and the rendering of feelings, thus showing the spirit and character of plum blossoms.

2. Expressed the author's lonely and melancholy mood. At arm's length, the author projected complex feelings on the plum blossom, but his thoughts were so numerous that he meditated under the plum blossom tree for a long time and left alone until dusk.

3. "The author's lonely and sad state of mind", but it seems that the author's purpose is not simply to recite these lonely feelings, but to express this lonely state of mind in "seeing plum blossoms-enjoying plum blossoms-folding plum blossoms", which can be regarded as "borrowing things to express feelings". However, the author's description is not accurate, which is slightly different from the poems we are used to seeing (Yu Shinan's "Chant", Lu You's "Yongmei" and so on. ).
