Cuatro de Mayo
The May Fourth Movement was an anti-feudal movement in the form of an interweaving of new and old ideas, and was carried out step by step, not overnight. As Wesleyan University professor Vera Schwarcz, said: "At the beginning of the May Fourth Movement, self-styled 'new youths' still saw themselves in terms of a traditional model". Many radical, political, and social leaders of the next five decades emerged at this time. In a broader sense, the term "May Fourth Movement" is sometimes used to refer to the period during 1915–1921 more often called the "New Culture Movement".
