《吕氏春秋·纪·仲夏纪》
古时阴康氏开始治理天下的时候，阴气过盛，沉积凝滞，阳气阻塞不通，不能按正常规律运行，人民精神抑郁而不舒畅，筋骨蜷缩而不舒展，所以创作舞蹈来加以疏导。
昔陶唐氏之始，阴多，滞伏而湛积，水道壅塞，不行其原，民气郁阏而滞著，筋骨瑟缩不达，故作为舞以宣导之。
In ancient times, when Yin Kang began to rule the world, the yin energy was too strong, stagnant and congealed, the yang energy was blocked and could not circulate normally, and the people were depressed and uncomfortable, their muscles and bones were curled up and not relaxed. So I created a dance to relax it.
