In ancient China, playing on a swing was not only a relaxation, but it is one of the activities during the Pure Brightness Festival. The swing was invented as a tool to help the people reach edible berries in high places. The Chinese word for the swing originally meant “moving around by holding leather ropes”. A Chinese legend has it that in the Spring and Autumn Period (770-476BC), the Shangrong ethnic group in north China invented the earliest swing. They swung by merely holding one rope with both hands. After the Han Dynasty, the swing itself evolved into what it is like today, with a plank between two long ropes dangling from a trellis. Later, playing on the swing became a game, especially for women, to practice physical agility as a form of exercise. Swinging high in the sky was great fun, almost like flying. Li Qingzhao (1084-1155), a poetess of the Song Dynasty, wrote in “Rouged Lips”, “she gets off the swing, too tired to care for her hands so fair. Like a slender flower under heavy dews, with sweat her light robe is went through.” It is clear that playing on a swing was quite common at that time. Since the Chinese folk would temporarily set up bamboo swings with bamboo racks in the suburbs, the Pure Brightness Festival got another name, that is, the Swing Festival.
