China experienced three historic changes in the 20th century: the Revolution of 1911, the founding of People's Republic of China (PRC), and the reform and opening up after the Third Plenary Session of the 11th CPC Central Committee. The May 4th New Culture Movement, with its unique enlightenment and vanguard, is independent of the first and second historical changes. The May 4th Movement is not only a watershed of China's revolution (old democratic revolution and new democratic revolution), but also an epoch-making symbol of China's social progress. Some researchers have pointed out that "the May 4th Movement is the all-round beginning of China's modernization" and "the May 4th Movement is a remedial course for the first historical upheaval and the starting point of the second historical upheaval". This view was put forward after looking at the position of the May 4th Movement in the historical process of China at the end of the 20th century, and its understanding is unique. The May 4th New Culture Movement is called the "last awakening" of the people, and the result of enlightenment is people's awakening and people's ideological liberation.

The May 4th Movement was the beginning of ideological emancipation, and the Yan 'an rectification movement and the discussion on the standard of truth were the continuation and development of the May 4th ideological emancipation. The influence of the May 4th Ideological Emancipation Movement is far-reaching. Some commentators pointed out that as a political movement or event, the May 4th Movement had a certain time limit, and its ideology, values and ideology were integrated into the modern political development of China. From the perspective of what, the historical interaction between culture and politics. The May 4th Movement marked the gradual transformation of China's political culture from tradition to modernity.
