101 years ago today, on May 1, 1924 (March 28, 1924, the lunar calendar), Sun Yat-sen called on workers to unite. On May 1, 1924, all walks of life in Guangdong gathered and marched to commemorate the May 1st International Labor Day. Sun Yat-sen attended the meeting and delivered a speech, calling on China workers to "stand up and form a large group of workers from today,""shoulder the responsibility of elevating the status of the country," and "turn China into the first-class power in the world." The conference was attended by 14 trade union groups including the Guangdong-Han Railway Trade Union, Seamen's Trade Union, Machinery Trade Union, and the General Federation of Trade Unions, as well as other transportation workers, students from various schools, and representatives of various districts of the China Kuomintang, totaling more than 10,000 people. Liao Zhongkai, Minister of Labor of the Central Executive Committee of the Kuomintang Party of China, is the chairman of the conference. Sun Yat-sen said: "China is now the poorest and weakest country in the world. It is subject to various oppressions by various countries. Its status is that of a slave. The slave status that China currently occupies is much lower than that of colonies of other countries. "" Since the status of the country is very low, the status of our people is naturally very low, and the status of workers is of course even lower." "In terms of economy, the China people are completely under foreign economic oppression. Although China is an independent country on the surface, it has actually become a colony of foreign countries." "Nowadays, in China, not only workers are oppressed by foreign capitalists, but also people who study, farm workers, and do business are oppressed by foreign economies. "He pointed out: " A few years ago, Russian workers formed a large group to overthrow the autocratic Russian emperor, reform the political system, and turn it into a dictatorship for workers. No capitalist was allowed to govern, and only workers could manage state affairs."" Workers in Britain and Russia are good examples for China workers." A parade was held after the conference. The slogans of the parade include: "One industry, one group","Apprentices do not work night","Standardize wages for peers","Participate in the National Revolution", etc. On the same day, more than 20,000 workers in Shanghai gathered to commemorate May Day International Labor Day.
