《徐霞客游记·闽游日记前》
从山腰上往右转一二里，忽然看到两座山脊交合的地方，四周荆棘覆盖，中间有齿状的石阶梯，盘旋往复于悬崖和狭窄的岩石之间。
从山腰右转一二里，忽两山交脊处，棘翳四塞，中有石磴齿齿，萦回于悬崖夹石间。
From the mountain waist, turning one or two miles to the right, we suddenly came across a place where two mountain ridges converged. Thorny vines covered the area, and in the middle was a toothed stone staircase, winding back and forth between cliffs and narrow rocks.
