How did the May 4th Movement negate traditional culture?

By the way, the May Fourth Movement absolutely did not deny traditional culture, the leaders of the New Culture Movement, such as Chen Duxiu, Lu Xun, Hu Shi, etc., all have deep roots in traditional culture, and they opposed feudal dogma, as well as feudal rituals and other backward things, not against traditional culture. Slogans such as "fight to the Confucian store" were only formed during the Cultural Revolution and were forced onto the New Culture Movement.
