In Hulunbeier, Inner Mongolia, from the Weiwei River, along the Ergun River to Heishantou Town, the border scenery of 200+km all the way is magnificent! Because at the border of the motherland, our drivers brother also held down my 18-time impulse to fly a drone until I came to Heshantou Town to live in the Mongolian Camp and finally took an aerial photography on the river near us. The afterglow of some sunsets.
