《徐霞客游记·滇游日记四十一》
穿过门往南出来，稍转向东下坡，半里，有水流自东曲向西，大树横架在流水上，过到桥南，这是大桥。
披门南出，稍转东而下坡，半里，有水自东曲而西，大木横架其上，南度之，是为大桥。
Pass through the door and go south. Turn to the east and go down the slope for half a mile. The water flows from the east to the west, and the big tree is placed across the water. After crossing to the south of the bridge, this is the big bridge.
