Beijing, December 29 (Youth.cn) - Before the New Year's Day in 2024, as temperatures rose, the ice layer on the riverbed of the Hukou Waterfall in the Qinjin Grand Canyon located on the Yellow River in Yan'an, Shaanxi Province fractured. The increased water flow over the waterfall created a magnificent scene. From the air, the once turbid Yellow River turned clear, with turbulent waters rushing down, breaking through the ice layer, forming a natural "ice bridge". This juxtaposed with the clear waterfall, creating a splendid and unique "ice bridge and clear waterfall" spectacle.
