阮籍
An old legend of the celebrated encounter between the two men has Ruan Ji visiting Sun Deng in his hermitage but not receiving any responses to his questions. Thereupon, he withdraws and, halfway up a distant mountain, lets out a loud, piercing whistle. This is followed by Sun Deng's magnificent whistled reply, which inspires Ruan Ji to write the "Biography of Master Great Man," an encomium in praise of the Taoist "true man" that also satirizes the conventional Confucian "gentleman".
