Sart
Sart lies among the grasslands and lakes of the Songnen plain, east of the Nen River. Its Mongolian name is associated with the moon, a fitting landmark in a country of broad skies and low shores. Pools and reed marshes punctuate the plain, where the waters of the Wuyuer spread out across the low ground. In the Qing period the wider country south of the Wuyuer was used by the Dorbod Mongols, whose herds grazed beside the river and its lakes.
