The photography work of Mr. Li Yingjie completely records four seasons of Saihanba. I know that is not good to distinguish the two seasons of spring and summer in Saihanba. In early June, trees on Saihanba just burgeon forth. In the picture, we can see the blue sky, white clouds, endless prairie, and tiny spots of Mongolian yurts adorned among them. This is the rare unspoiled prairie in the world. In this fairyland, we can see green colors of Saihanba, such as the earth, hills, fields and lakes. Distant villages, melodious pastoral and waving sheep flock, all of these will bring me into a fantastic world of serenity
