The clear spring penetrates the stone, the flowing clouds emerge, and the bamboo swaying and the rattan floats are regular scripts. This is a rhetorical device that uses metaphor. The font is compared to a clear spring piercing the stone, flowing clouds emerging, bamboo swaying and vines floating, and the rhetorical technique of parallelism is also used. Clear springs penetrate the rocks and flow clouds out of the Ao, which means clear spring water penetrates the rocks, and drifting clouds pass through the deep places in the mountains.
