May 4th Youth Day originated from the May 4th Movement of China in 19 19. The May 4th Patriotic Movement was a patriotic movement that was thoroughly anti-imperialist and anti-feudal, and it was also the beginning of China's new-democratic revolution. 1939, the Northwest Youth Salvation Federation in the Shaanxi-Gansu-Ningxia Border Region designated May 4th as China Youth Day. Because the patriotic movement is mainly attended by patriotic young students, it has great historical and commemorative significance. This festival has been used ever since.
1922 in may, under the direct leadership of the party, the China socialist youth league held its first national congress in Guangzhou and established a national unified organization. 1925 1, at the Third National Congress of the Communist Youth League, it was decided to rename the China Socialist Youth League as the China Productive Youth League. Now it's the Youth League.
The two are staggered in time, and the reasons for their establishment are different, and there is no necessary connection and relationship.
