What do poets of lime songs and bamboo stones use to express their ambition to be a man and stick to their moral integrity?

Ode to Lyme This is a poem expressing feelings. The author uses lime as a metaphor to express his strong and unyielding quality, lead an honest and clean life and his inadaptability. After hammering into the mountains for thousands of times, the fire is still there. Even if it's smashed to pieces, why be afraid? Just to keep a piece of blue and white in the world (as clear as the color of a stone, now often used as "innocence"). The author of this poem is Yu Qian, a poet in the Ming Dynasty. Yu Qian is a national hero and an honest official who enjoys equal fame with Yue Fei. Lyrics of Lime is a lime hymn written by Yu Qian when he was 17 years old. Through the anthropomorphic description of the lime making process, he expressed his fearless spirit of not being afraid of difficulties and sacrifices and his lofty ambition of innocence and integrity.
