Note : About the Origin of International Labor Day .

May 1st International Labor Day originated from the strike of workers congresses in Chicago USA. 

On May 1st,1886, more than 216,000 workers in Chicago went on a general strike for the eight-hour work working system. After a painstaking and bloody struggle, they finally won. In memoration of this great workers movement, the Second International announced in July 1889 that May 1st will be designated as the International Labor Day every year.

The significance of International Labor Day lies in the fact that the laborers have won their legitimate rights and interests through struggle and with indomitable and heroic spirit of struggle. This is the historical progress of human civilization and democracy. It is the essence of May Day, also the reason why people pay so much attention to Labor Day .
