What feelings does the author express with "early plum"

Liu Zongyuan used the metaphor of "early plum blossom" and "early plum blossom towering into the sky" to describe the author's early success. Then he praised Zaomei for braving the north wind, breaking the harsh frost and floating a faint fragrance, showing her innocence. The poet's noble and fragrant plum blossoms are not afraid of cold and frost, which is a portrayal of the author's loyalty, self-restraint and purity. Comparing things with people, she was banished to a far place and wanted to give plums to her friends. Besides, this early plum will wither. How sad and painful it is, the feeling of sadness cannot be expressed. In fact, it is not difficult to taste the pain and loneliness in the author's heart from this poem. Enjoy good things with others. Good food is a kind of enjoyment, but he can't. He just thought of making friends with plums in a hopeless situation, worried about the long journey, and finally gave up the idea of giving friends. The poet actually wrote plum blossoms and secretly conveyed his feelings.
