New Culture Movement: Chen Duxiu establishes the New Youth magazine in Shanghai.

The New Culture Movement was a progressive sociopolitical movement in China during the 1910s and 1920s. Participants criticized many aspects of traditional Chinese society, in favor of new formulations of Chinese culture informed by modern ideals of mass political participation. Arising out of disillusionment with traditional Chinese culture following the failure of the Republic of China to address China's problems, it featured scholars such as Chen Duxiu, Cai Yuanpei, Chen Hengzhe, Li Dazhao, Lu Xun, Zhou Zuoren, He Dong, Qian Xuantong, Liu Bannong, Bing Xin, and Hu Shih, many classically educated, who led a revolt against Confucianism. The movement was launched by the writers of New Youth magazine, where these intellectuals promoted a new society based on unconstrained individuals rather than the traditional Confucian system. In 1917, Hu Shih put forward the famous "eight principles", that is, abandon the ancient traditional writing method and use vernacular.

Chen Duxiu was a Chinese revolutionary, writer, educator, and political philosopher who co-founded the Chinese Communist Party (CCP) with Li Dazhao in 1921, serving as its first General Secretary from 1921 to 1927. Chen was a leading figure in the New Culture Movement and May Fourth Movement of 1919, which significantly influenced China's intellectual and political landscape in the early 20th century.

New Youth, also known as La Jeunesse, was a Chinese literary magazine founded by Chen Duxiu and published between 1915 and 1926. It strongly influenced both the New Culture Movement and the later May Fourth Movement.
