What are the attitudes of Chen Duxiu and Li Dazhao towards China's traditional ethics?

Chen Duxiu said: "Strongly advocating the abolition of Chinese characters and China characters is not only difficult to carry new things and new ideas, but also a nest of corrupt ideas, and the sincerity of abolition is not enough." Lu Xun said: "Chinese characters do not die, and China dies." Qu Qiubai: "Chinese characters are really the dirtiest, worst and most asshole medieval pits in the world." Li Dazhao advocates the latinization of Chinese characters. After 1949, Chinese characters were almost abolished and pinyin was adopted. Can't blame them. China was weak in modern times, and the people of China had suffered enough. Many China intellectuals believe that these are all caused by the traditional cultural system of China. Only by overthrowing these feudal cultures can China have hope. At that time, people in China thought there was nothing good about China.
