《徐霞客游记·滇游日记二十九》
两旁夹立的石崖如像刀劈出来的样子，中间垂着一个洞穴，水捣着岩石流下去，石蹬紧靠石壁上登，人就像破开石壁专摸天，水好像为了争道跃过山门，两者互相不退让。
两崖夹石如劈，中垂一霤，水捣石而下，蹬倚壁而上，人若破壁扪天，水若争道跃颡，两不相逊者。
The stone cliffs on both sides stand like they were cut out with a knife, and there is a cave in the middle, where the water flows down against the rock, and the stone steps are close to the stone wall. People are like breaking through the stone wall to find the sky, and the water seems to be fighting for the way. Leap over the mountain gate, neither of them will give way.
