Literature Reference: The superior man uses bells and drums to express his aspirations, and uses qin and se to delight his heart. He moves with shields and axes, adorns with feathers and banners, and follows with pipes and flutes. Thus, his clarity resembles heaven, his vastness resembles earth, and his movements resemble the four seasons. Therefore, when music is performed, his aspirations are clear; when rituals are cultivated, his conduct is perfected. His ears and eyes are intelligent, his blood and qi are balanced, and customs are transformed, bringing peace to the world, where beauty and goodness are mutually joyful.
