Guma

Guma is an oasis on the southern rim of the Tarim Basin, between Yarkand and Khotan. Rivers from the Kunlun Mountains water its fields before disappearing into the dry country northward. The district was known in Han records as the kingdom of Pishan, one of the small oasis states along the southern road. Its position linked the fertile lands of Khotan with the routes west toward Yarkand.
