During the May Fourth New Cultural Movement,three debates on new/West and old/Chinese cultures were respectively carried out between the joal New Youth and Lin Qinnan,Chen Duxiu and Du Yaquan,as well as Zhang Dongsun and Fu Sinian.New Youth,Chen Duxiu and Zhang Dongsun were regarded as the new school, whereas their opponents the old new-intellectuals. The difference between them lies in their attitudes towards traditions instead of their new or old knowledge.After three heated debates,New Youth won a total victory in big cities,because the so-called urban youths needed a radical cultural reform plan and a simple guide for action.On the contrary,town youths who lived in small cities and towns did not care about the attitudinal difference of two sides.They paid more attention to absorbing new knowledge from both sides and were more sympathetic to tradition.
