《徐霞客游记·滇游日记四十一》
桥下的水就是右甸河的下游，往东流向南转，到此处向西折过桥下，又绕过西边的山崖往南流去，已成浩浩荡荡的河流。
桥下水即右甸下流即今之右甸河，东行南转，至是西折过桥，又盘西崖南去，已成汤汤之流。
The water under the bridge is the lower reaches of the Youdian River. It flows eastward to the south, turns westward here and crosses under the bridge, then flows around the cliff on the west side to the south, and has become a mighty river.
