《孟子·梁惠王章句下·第一节》
假如大王在演奏音乐，百姓们听到大王鸣钟击鼓、吹萧奏笛的音声，都眉开眼笑地相互告诉说： 我们大王大概没有疾病吧，要不怎么能奏乐呢？ 
今王鼓乐于此，百姓闻王钟鼓之声，管籥之音，举欣欣然有喜色而相告曰： 吾王庶几无疾病与？何以能鼓乐也？ 
If Your Majesty is playing music, and the people within hearing of Your Majesty's bells and drums, and your reed organs and flutes, are all looking cheerful and saying to one another, "Our ruler is no doubt in good health and free from ailments; otherwise how could he have the heart for music?"
