This is the sound of a pier in Nagasaki. The metal pier went up and down being hit by the ocean waves. Meanwhile, a family of Chinese tourists were taking pictures in front of the pier. “Sān, èr” says the father who was taking the picture of his wife and child. In the distance is the sound of boat signal that was docking. Since a long time ago, Nagasaki has been the connector between Japan and the outside world.
