Lefu

Lefu is associated with the upper reaches of the Mudan River, known in Qing geographical writings as the Lefushan. Rising in the hills of the Changbai country, the river runs northeast toward Lake Bilten, also called Jingpo. Below the lake its waters continue as the Hurka, eventually joining the Songhua. Forested slopes and streams surround the upper course, forming part of a river system that connected the interior of Manchuria with the great northern waterways.
