Chen Duxiu, who was dean of Peking University's school of humanities, went the whole hog. When he rejected Confucianism, he parodied Confucian teachings by saying: "Of all sins, filial piety is the worst; of all virtues, licentiousness is the greatest." When he was converted to Marxism, he took it on board completely and promoted it without reservation.
擔任北大文學院長的陳獨秀更是直線進行，要打倒孔家店，就說「萬惡孝為首，百善淫為先」；他相信馬克思主義，也就完全俯首稱臣，毫無保留的加以發揚。
