Continuous heavy snowfall has blanketed the larch forest in Qinyuan County, north China's Shanxi Province. It's the largest plantation forest of larch in northern China, covering an area of more than 60 square kilometers. The Guangwu section of the Great Wall has also become a world of silver in Shanyin County, on the edge of Shuozhou City. It's one of the best-preserved sections of the Great Walls built in the Ming Dynasty (1368-1644).
