Tan's Beauty in a Bottle mainly uses the method of comparison to compare the beauty in a bottle with the beauty in a mountain. The plum blossom in the bottle bloomed late, but it blossomed after all. Although it is not like the spring breeze and rainy night in Shan Mei, plum blossom is lonely in the bottle, but it adds charm because of loneliness. In particular, the poet's last couplet, "A tree in a mountain, a tourist or a nameless one." The poet prefers bottled plums to Shan Mei.
Tan is a famous writer and literary theorist in ancient China. However, in his life, he spent many years on the road of imperial examination and suffered greatly from it. He has been trapped in all kinds of life for a long time and tried every time. Bottle of plum is also a portrayal of the poet's life.
