English: An aerial view of the Valley of the Tangwang River (a left tributary of the Sungari) in and around Haolinghe Town, Nancha District, Yichun City, Heilongjiang Province, China. Looking roughly north. The river forms a winding valley as it passes through the Qinghei Mountains (Qingheishan), a southern branch of the Lesser Khingan. One can see the Jiamusi-Nancha railway winding its way across the mountain range, more or less following the river valley. Haolinghe Town center is at the large river bent, toward the lower left part of the picture.
