《徐霞客游记·粤西游日记二》
夹谷半腰上两侧的崖璧上都有裂痕，把脚踩进去，两肩紧靠分开的崖壁，脚踏着线一样的裂痕，手攀着石孔，没有坠落下去的担忧。
夹半两崖俱有痕，践足而入，肩倚隔崖，足践线痕，手攀石窍，无陨坠之虑。
There were cracks on the cliffs on both sides at the waist of the clip valley, putting my feet in, my shoulders close to the separated cliffs, my feet stepping on cracks like lines, my hands climbing the stone holes, without worrying about falling down.
