This poem, with the theme of "bamboo", uses symbolic techniques to express the poet's indifference to fame and fortune, his commitment to relieving the sufferings of the people, and the spirit of "I will stand when the wind and rain come". In this paper, the author uses bamboo to compare people, which is novel and strange, and makes a solemn and unyielding scholar very reasonable, showing his high standards, uniqueness and full love for the people.
