Literature Reference: 君子以钟鼓道志，以琴瑟乐心。动以干戚，饰以羽旄，从以箫管。故其清明象天，其广大象地，其俯仰周旋有似于四时。故乐行而志清，礼修而行成，耳目聪明，血气和平，移风易俗，天下皆宁，美善相乐。—— 《礼记·乐记》 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.
