Daqinggou lies on the southern field of Tongliao City (Zhelim League), bordering the Korqin Sand Belt, which is about 250 kilometers long. The deep valley of Daqinggou consists of east and west double ditches, each of which is more than 10 kilometers long. The cross of the double ditch is a human shape, the ditch is more than 100 meters deep, and the width is about 200-300 meters. It has been extended into Liaoning Province. Daqinggou and the sandy phenomenon outside the ditch form a stark contrast. The small river in the ditch is flowing, clear and clear, and the entrance is sweet and beautiful. The scenery in the ditch is even more beautiful, like a dream world.
