When the bitter cold wind swept across Beijing, many canyon streams condensed into icefall wonders of various shapes under the action of low temperature.
The icefalls hanging in the mountains are white and crystal clear. Some are like huge crystal curtains, pouring down from the cliffs, crystal clear; some are like layers of stacked icicles, thick and upright, arranged in a staggered manner.
Other icefalls present strange shapes, like smart dancers with graceful postures; like eagles spreading their wings and ready to fly, magnificent, highly ornamental and artistically beautiful, like a real version of "Frozen", feeling the magic of nature.
