《徐霞客游记·粤西游日记三十七》
这是北面的支流；而司城北边五里的，又是都泥江北面的支流；司城南面与思恩府九司交界相隔的，是都泥江南面的支流。八桐、石壁村的水流，流入金城江下游可想而知。
其上则滩高水浅，不能上矣。北江通小舟，三四日至中州。
This is the tributary from the north; the one five miles north of the city is the tributary north of the Duni River; the one on the south side of the city, which borders the Jiusi of Si'en Prefecture, is the tributary south of the Duni River. The water flowing from Batong and Shibi villages flows into the lower reaches of Jincheng River, as can be expected.
