The grassland trip is really worthwhile. I saw the grassland scenery on the prairie of Inner Mongolia, the blue sky and white clouds, and the boundless green grassland. On the way to Jiuqu Bay, we stopped several times and took pictures of the grassland scenery on the roadside. The beauty of the grassland is the beauty of the undulations of the terrain, the beauty of the difference in the color of the vegetation, and the beauty of the light and shadow that changes with the movement of the clouds. Step by step, blue sky and white clouds, the clouds are moving, the light is changing, the light and shadow in front of the eyes are like the pictures selected by the film, and the ups and downs continue to surprise.
