Which poem in Lime Song and Bamboo Stone is a metaphor for suffering?

The poem of lime (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. Even if it is smashed to pieces, I am not afraid, and I am willing to leave a clean one in the world.

Zhu Shi (Zheng Xie. Qing dynasty)

Bamboo is not relaxed at all, its roots are firmly embedded in the cracks in the rocks. After thousands of tortures and blows, it is still strong, whether it is the southeast wind or the northwest wind in winter, it can bear it and will still be tough and straight.
