From 《
礼记·
曲礼上》 (Book of Rites, Qu Li): 'Ritual does not extend down to commoners; punishment does not extend up to grand officers (dafu).' The Zhou-era principle that the aristocracy was to be held accountable through ritual demotion, exile, or self-imposed suicide rather than public corporal punishment. Today almost always invoked critically - as the attitude modern rule-of-law must reject.
