Prior to this, the international women's liberation movement was growing. 1909 on March 8, a large-scale women's strike demonstration broke out in Chicago, USA. Women workers put forward to oppose the exploitation and oppression of capitalists, strive for freedom and equal rights, and demand an 8-hour working system and higher wages. 19 10, the second international conference on socialist women was held in Copenhagen, Denmark. At the meeting, Ms. Tsetkin, a German proletarian revolutionary and secretary of the International Women's Secretariat, proposed to designate March 8 every year as World Women's Struggle Day, which was unanimously adopted by the delegates. Since then, "March 8" has become a festival for working women all over the world to strive for freedom and equal rights and women's liberation.
