This poem adopts "abstract theme, concrete writing" and has new features. This is mainly manifested in the use of symbolism in the whole poem, that is, in the form of "fable poem", the old crow is fully personified, and the ideological style of the advocates of the new culture movement is revealed through the tone of the old crow-inner monologue. Only in this way can each line of this poem have rich social and political connotations. For example, the first song "I got up early in the morning,/Standing in the corner of someone else's house crying dumb" not only vividly depicts the scene that the advocates of the new culture movement actively attacked the old ideas and culture, but also indicates the inevitable ideological struggle. The so-called "people hate me and call me unlucky" shows the inevitability of the conflict between old and new ideas at that time. As for the second paragraph, "it's cold and windy, and there's nowhere to live" and "I fly around all day, and I'm hungry and cold all day", it is obviously a metaphor for the hardships that advocates of the New Culture Movement struggle for their lives. It is precisely because of the above-mentioned poems as the background to explain, so that the infinite emotional words spoken in the tone of the old crow in the poems are more emotional and more enough to arouse the readers' * * *.
