Introduction to the Memorial Square of the Huayuankou Incident: It is the place where the embankment was blocked in 1946 after the Kuomintang government opened it. There is one "Memory Stele of the Yellow River Huayuankou Ferry Break" erected by the Water Conservancy Commission. Two hexagonal glazed tile pavilions stand opposite each other. There is a six-sided column stone stele in each pavilion. In the middle is a large relief wall reflecting this historical event.
