《徐霞客游记·游颜洞记》
我决心一定要去到洞口，当地人说： 必须渡过沪江，到江南岸，顺着峡谷进去，就是走所说的沪江桥大路。 
余必欲一至洞门，土人曰： 须渡江南岸，随峡入，所谓泸江桥大道也。 
I was determined to go to the entrance of the cave, and the locals said: You have to cross the Hujing River, go to the south bank of the Yangtze River, and follow the canyon to enter, that is, take the Hujing Bridge Road.
