Introduction to Hukou Waterfall on the Yellow River: Hukou Waterfall is a natural waterfall formed when the middle reaches of the Yellow River flows through the Qinjin Grand Canyon. When the Yellow River reaches this point, the torrent of more than 300 meters wide is suddenly restricted by both banks. It is wide at the top and narrow at the bottom. It surges and pours in a drop of 50 meters. The momentum is like pouring out of a huge pot, so it is called "Hukou Waterfall". It is known as the hanging lake in the sky. Usually, when entering the "hukou", there will be a scene of "smoke from the bottom of the water", that is, the rapids splash and form water mist in the air. "Dry Land Boating", "Hukou Autumn Wind", "Neon Sky" and the ice waterfall wonders that appear in winter are also very famous landscapes of Hukou Waterfall.
