《水经注·卷二十四》
如果济水分支东流，显然不会以时水为名。探究时水和济水，再没有别的水流向南延伸到华县和费县地界了。
非济入时，盖时来注济，若济分东流，明不得以时为名。寻时，济更无别流，南延华费之所，斯为谬矣。
If the Jishui River branches to the east, it would obviously not be named after the Shishui River. Exploring the Shishui River and the Jishui River, there is no other river flowing south to reach the boundaries of Huaxian and Feixian.
