《徐霞客游记·游嵩山日记》
我拄着拐杖独自往前走，愈下去愈没有路，很久才到崖底。其岩比不上卢岩雄伟开阔，但幽深峻峭则超过卢岩。
余策杖独前，愈下愈不得路，久之乃达，其岩雄拓不如卢岩，而深峭过之。
I walked forward with my crutches alone. The more I went down, the less road there was. It took a long time to reach the bottom of the cliff. Its rock is not as magnificent and broad as Luyan, but it is more secluded, steep and precipitous than Luyan.
