《水经注·卷三十八》
又往北流，有三溪水口，三溪水在东边承接大湖，西与湘浦相通，三水汇合，所以有三溪之名。
又北得三溪水口，水东承大湖，西通湘浦，三水之会，故得三溪之目耳。
Then it flowed north again, and there were three creeks, the three creeks took over a large lake in the east, and were connected to the Xiangpu River in the west, the three waters converged, so it was named Sanxi.
