From Qu Yuan's (
屈原) Warring-States-era dialogue
《渔父》 (The Fisherman), part of
《楚辞》. Exiled from the Chu court, Qu meets a fisherman and explains why he won't compromise:
举世皆浊我独清,
众人皆醉我独醒 - 'the whole world is muddied, I alone am clear; everyone is drunk, I alone am sober'. Shortly after he drowned himself in the Miluo River, commemorated annually at Dragon Boat Festival.
