In early autumn, the Chou'er River is veiled in mist in the Greater Hinggan Mountains. The flickering sunlight pierces through the colorful mist, mixed with the chimney smoke, the dreamy forest and the peaceful village resemble a fairyland. 

Since the summer ends and the weather turns cooler, the mist will develop more often in autumn. When the warm ground and river interact with the cold air, the moisture near the ground forms water droplets, which is mist. If the mist is dense and one cannot see further than 1,000 meters, then it is fog.
