  On 4 May 1919, students in Beijing gathered at Tiananmen to protest the Chinese government's weak resistance to Japanese expansion in China. Patriots were outraged at the influence given to Japan in the Twenty-One Demands in 1915, the complicity of Duan Qirui 's Beiyang government, and the betrayal of China in the Treaty of Versailles, wherein Japan was allowed to receive territories in Shandong which had been surrendered by Germany. These demonstrations ignited the nationwide May Fourth Movement and fuelled the New Culture Movement which blamed China's diplomatic defeats on social and cultural backwardness.
  
  In Changsha, Mao had begun teaching history at the Xiuye Primary School and organising protests against the pro-Duan Governor of Hunan Province, Zhang Jingyao, popularly known as "Zhang the Venomous" due to his corrupt and violent rule. In late May, Mao co-founded the Hunanese Student Association with He Shuheng and Deng Zhongxia, organising a student strike for June and in July 1919 began production of a weekly radical magazine, Xiang River Review. Using vernacular language that would be understandable to the majority of China's populace, he advocated the need for a "Great Union of the Popular Masses", and strengthened trade unions able to wage non-violent revolution. His ideas were not Marxist, but heavily influenced by Kropotkin's concept of mutual aid.
  
  Zhang banned the Student Association, but Mao continued publishing after assuming editorship of the liberal magazine New Hunan (Xin Hunan) and authored articles in popular local newspaper Ta Kung Pao. Several of these advocated feminist views, calling for the liberation of women in Chinese society; Mao was influenced by his forced arranged-marriage. In fall 1919, Mao organized a seminar in Changsha studying economic and political issues, as well as ways to unite the people, the feasibility of socialism, and issues regarding Confucianism. During this period, Mao involved himself in political work with manual laborers, setting up night schools and trade unions. In December 1919, Mao helped organise a general strike in Hunan, securing some concessions, but Mao and other student leaders felt threatened by Zhang, and Mao returned to Beijing, visiting the terminally ill Yang Changji. Mao found that his articles had achieved a level of fame among the revolutionary movement, and set about soliciting support in overthrowing Zhang. Coming across newly translated Marxist literature by Thomas Kirkup, Karl Kautsky, and Marx and Engels—notably The Communist Manifesto —he came under their increasing influence, but was still eclectic in his views.
  
  Mao visited Tianjin, Jinan, and Qufu, before moving to Shanghai, where he worked as a laundryman and met Chen Duxiu, noting that Chen's adoption of Marxism "deeply impressed me at what was probably a critical period in my life". In Shanghai, Mao met an old teacher of his, Yi Peiji, a revolutionary and member of the Kuomintang (KMT), or Chinese Nationalist Party, which was gaining increasing support and influence. Yi introduced Mao to General Tan Yankai, a senior KMT member who held the loyalty of troops stationed along the Hunanese border with Guangdong. Tan was plotting to overthrow Zhang, and Mao aided him by organising the Changsha students. In June 1920, Tan led his troops into Changsha, and Zhang fled. In the subsequent reorganisation of the provincial administration, Mao was appointed headmaster of the junior section of the First Normal School. Now receiving a large income, he married Yang Kaihui, daughter of Yang Changji, in the winter of 1920.
