Workers" protests were held around the world to commemorate this great labor movement and to protest the subsequent sentencing. These activities became the forerunner of international labor day.

In July 1889, Engels organized the second international founding conference announced the annual May 1 as international labor day.

May 1st International Labor Day originated from the strike of workers"congresses in Chicago, USA. On May 1, 1886, more than 216,000 workers in Chicago went on a general strike for the eight-hour work system.

After a painstaking and bloody struggle, they finally won.

In commemoration of this great workers"movement, the Second International announced in July 1889 that May 1 will be designated as International Labor Day every year. This decision was immediately responded positively by workers from all over the world.

On May 1, 1890, the working class of European and American countries took the lead in going to the streets and holding grand demonstrations and rallies to fight for legitimate rights and interests. Since then, the working people of all countries in the world have gathered and marched to celebrate this day.

5月1日國際勞動節起源於美國芝加哥工人代表大會的罷工，1886年5月1日，芝加哥有216000多名工人舉行了8小時工作制的大罷工。經過艱苦奮鬥，他們終於勝利了。為了紀念這一偉大的工人運動，第二國際於1889年7月宣佈，每年5月1日將被定為國際勞動節。這一決定立即得到了來自世界各地的工人的積極響應。1890年5月1日，歐美國家工人階級率先上街，舉行盛大的示威遊行，爭取合法權益。從那時起，世界各國的勞動人民聚集在一起，遊行慶祝這一天。
