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").
Limestone hymn
Yu Qian
original text
It can only be extracted from the deep mountains after being struck by thousands of hammers. It regards the burning of the burning fire as a very common thing.
I'm not afraid of fractures. I want to leave my innocence in the world.

(Limestone) can only be mined from the deep mountains after thousands of hammering. It regards the burning of blazing fire as a very common thing.
Even if it is shattered, it is not afraid. It is willing to leave a clean body in the world.
