From February to April, Japanese cotton mill workers in Shanghai and Qingdao, under the leadership of China * * * Production Party, organized tens of thousands of workers to hold a large-scale strike struggle and achieved great victory, which was suppressed by Japanese imperialism and Beiyang warlords. Japanese imperialism colluded with the Beiyang warlord government in an attempt to undermine the workers' movement and brew a new bloody massacre. On May 14, workers of Japanese cotton mill in Shanghai went on strike again to protest against the unreasonable dismissal of workers by Japanese employers. Japanese capitalists shot and killed worker Gu Zhenghong (party member) and injured more than one worker 10, which aroused the strong anger of Shanghai workers, students and citizens. At the same time, the Shanghai imperialists put forward "four proposals" that damaged China's sovereignty and attacked China's national industry and commerce (adding articles of association, increasing dock donations, registering exchanges and so-called "banning heavy industry bill"), and decided to pass them at the Shanghai taxpayer meeting on June 2, which aroused strong opposition from people from all walks of life in Shanghai, including the national bourgeoisie. On May 28th, according to the development of the movement, the Central Committee decided in time to further mobilize the masses to carry out the political struggle against imperialism. On May 30th, more than 2,000 Shanghai students distributed leaflets and delivered speeches in the concession, protesting against the suppression of workers' strike by Japanese yarn factory capitalists, killing workers Gu Zhenghong, supporting workers and calling for the recovery of the concession. More than 65,438+000 people were arrested by the British police. In the afternoon, more than 10,000 people gathered at the gate of Nanjing Road in the British Concession, demanding the release of the arrested students and shouting slogans such as "Down with imperialism". The British patrol shot and killed 1 1 on the spot, causing numerous casualties, which led to the May 30th tragedy that shocked China and foreign countries. The news of the May 30th tragedy quickly spread throughout the country, and major and medium-sized cities went on strike in succession to support the anti-imperialist struggle of the Shanghai people. As a result, the May 30th anti-imperialist patriotic movement was formed in a wider scope, which dealt a heavy blow to imperialism, greatly improved the consciousness of the people of China and opened the prelude to the climax of the Great Revolution.
