1919年爆发的五四运动,是中国近代历史上首次由学生、工人和其他群众掀起的反对帝国主义、反对军阀卖国的全国规模的反帝爱国斗争。1920年4月22日,陈独秀在中国公学第二次讲演会上的讲演中,就做出结论:“我以为五四运动的发生,是受了日本和本国政府的两种压逼而成的,自然不能说不是爱国运动。” The May Fourth Movement, which broke out in 1919, is the nation-wide anti-imperialist patriotic struggle against imperialism and against the sale of warlords by the students, workers and other masses for the first time in modern Chinese history. On April 22, 1920, Chen Duxiu made a conclusion in his speech at the second lecture of China’s public school: “I thought that the May 4th Movement was caused by two kinds of repression by Japan and its own government Into, of course, can not be said that patriotic movement. ”
