Introduction to Mengmen Mountain: Looking down from the Yellow River Bridge at the junction of Qin and Jin, the river bursts out of the dragon trough and suddenly opens up. Where the water surface gradually widens, two huge reefs stand in the middle of the river. They are actually two small islands, named Da , Xiao Mengmen Mountain. They dominate the middle stream and cut through the river, which is the Mengmen Mountain in the legend that "the rocks were chiseled by Yu". When the river water falls, visitors can view the island and see the four one-meter-square vermilion characters "Lying Town Crazy Current" written by Jinming County Governor on the Mengmen boulder.
