May Day originated from the workers' strike movement in Chicago, USA in 1886. On May 1, 1886, an 8-hour strike movement broke out in Chicago, USA, ending in the victory of the workers, declaring the victory of the proletarian workers and fighting for their rights.
After the establishment of the People's Republic of China, the State Council of the Central People's Government designated May 1st as the statutory Labor Day in December 1949.
May Day also teaches children and adolescents to cherish their own and others' labor achievements, exercise their labor abilities, and establish a correct view of labor.
