Sunset introduction: A railway bridge connects Nan Tongpu Road and Longhai Road, turning the Yellow River's natural chasm into a thoroughfare. The 1,500-meter-long Yellow River Bridge spans the north and south banks, connecting the people of the three provinces. The Yellow River Diversion Electric Irrigation Station on Fenghuangzui irrigates thousands of hectares of fertile farmland. Standing on the Fenghuang Mouth on the river bank, overlooking Tongguan, you can clearly see Taihua and Xiaohan, and the waves of the Yellow River below are majestic.
