Leaves of Grass contains Whitman's life's creation, with more than 300 poems. The blade of grass is the most common and vital thing, symbolizing the vigorous development of America at that time. Through the feeling of "self" and the image of "self", the poetry anthology enthusiastically praised the United States in the rising period of capital, capital, subjectivity and justice, and it was also a brilliant milestone in the history of American poetry.
The author made a bold innovation in the form of poetry, creating a poetic form of "free poetry", breaking the traditional poetic rhythm, taking sentence breaks as the basis of rhythm, and the rhythm is unrestrained.
