海河
The Wei River (, "Wèi Hé", also spelled as Wey River) of Shandong Province and Henan Province is a long tributary of the Hai River. Beginning in the southern foothills of the Taihang Mountains in Xinxiang County of Henan Province, the Wei River meets the Grand Canal at Linqing in northwest Shandong province and more or less parallels the Yellow River at some distance for several kilometers before flowing into the Hai River near Tianjin.
