Ice waterfall introduction: Waterfalls are a natural flowing music in nature. They rush and jump in the valley, and their irresistible enthusiasm and vitality burst out in an instant. Sometimes it is surging and powerful, like a rainbow; sometimes it is fluttering and has a long lasting charm. But when winter comes, they restrain their inner sharpness and become much more showy. Strips turned into icicles, hanging between the steep rock walls, crystal clear and shining, like a dreamy crystal palace.
