Lyrics of lime

Author Yu Qian, Ming Dynasty

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.

Not afraid of broken bones, leaving 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.
