Hukou Waterfall has turned to ice amid a drop in temperatures in Jixian County, north China's Shanxi Province. The Yellow River pouring over the cliff and the small frozen waterfalls on both sides unite to create a spectacular scene that wows visitors. More parts of the Hukou Waterfall are expected to freeze in the coming days, allowing more tourists to appreciate the beauty and charm of winter. Hukou Waterfall is on the Yellow River, on the border area between north China's Shanxi and northwest China's Shaanxi provinces.
