Lyrics of Lyme is a poem that expresses feelings with objects. The writer is Yu Qian, a poet in Ming Dynasty. Yu Qian is a national hero and an honest official who enjoys equal fame with Yue Fei.
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").
