《徐霞客游记·滇游日记二十二》
走八里，才有澳往东流，道路转东走而往南渡溪，于是东边看得到演武场北村，西边看到西龙潭大村，原来此溪水是西龙潭分流出来的。
八里，始有溪东注，路东转而南渡之，于是东望为演武场北村，西望为西龙潭大村，盖此水即西龙潭所分注者也。
After walking eight miles, you will see Aowang flowing eastward. The road turns eastward and heads southward to cross the stream. Then you can see Yanshichang Beicun in the east and Xilongtan Dacun in the west. It turns out that the water of this stream is diverted from Xilongtan.
