　　The Swing

　　The origin of swing can be traced back to the antiquity. Those tools for climbing trees or crossing streams are the embryonic forms of swing. Since the Han Dynasty, swinging has gradually become a folk activity performed on the Tomb-sweeping Day and some other festivals. Swing is a kind of game utensil while swinging is a sport. The player may sit or stand on something like a pedal which is hung by two long ropes on a frame and swing back and forth. Swinging can be categorized into many forms, such as the single swing, double swing and so on.
