The middle and lower reaches of the Emur River are dominated by plain terrain, which is flat and the river flows slowly. The river is mainly eroded laterally, and the concave bank of the river is eroded and the convex bank accumulates, which leads to the meandering development of the river. The lateral erosion of the river is getting bigger and bigger, forming a landform with nine bends and eighteen bends.
The Emur River, which originated in the pheasant farm mountain in the northern Daxing 'anling Mountains, flows through Mohe River and flows into Heilongjiang near Dahexi Village in Xing 'an Township.
