《徐霞客游记·滇游日记十》
河水从桥下往南流去，蝗螂川水从武趣河西边峡谷中转往北流来，与沙河水在桥南汇合，半里，就往西北流到安宁州城的南部，从这里往北流经安宁州城东面而再往北流去。
河从梁下南去，螳川之水，自武趣西峡转而北来，二水合于梁南，半里，遂西北至安宁州城之南，于是北向经城东而北下焉。
The river flows south from under the bridge. The Huanglangchuan water flows north from the canyon on the west side of the Wuxu River, meets the Shahe water at the south of the bridge, and flows northwest for half a mile to the south of the city of Anningzhou. From here, it flows north through the east of Anningzhou City and then continues north.
