International Labor Day originated in Chicago.
Workers fight for their rights and riot and shed blood.
The whole world supports it and the world unites with one voice.
The eight-hour work system is determined to fight from now on.
After a hundred years of vicissitudes, old cars have returned to their old ways,
A black-hearted boss can never make too much money,
Hire children as laborers, and they will be tortured for a long time,
Violating labor laws and relying on exploitation to operate.
How can workers survive when it is difficult to prohibit orders?
