Introduction to the ferry head: The upper reaches of the river dam is the "ferry head" that connects Longmen and Gexi Mountain. The slope made of stones slowly stretches towards the center of the river, becoming the pier, the same on both sides. There is a blacksmith shop on this side of the "ferry head" and a blacksmith shop on that side. The two blacksmith shops make a "ding-dong" sound with the same rhythm on both sides of the river. In my memory, this is the most spectacular and natural concerto. Old boatmen shuttled back and forth in the concerto, and urchins jumped from the ferry into the river, causing waves.
