First, it marks that China has become a semi-colonial and semi-feudal society, and the people of China are facing the dual tasks of oppression, anti-imperialism and anti-feudalism.

The Taiping Heavenly Kingdom movement dealt a heavy blow to the rule of the Qing Dynasty, but due to the blindness and limitations of the Taiping Heavenly Kingdom itself, it finally failed.

The Revolution of 1911 ended the feudal rule of China for more than 2,000 years and changed the nature of society, but the face of society did not fundamentally change. The people of China are still oppressed by feudal warlords and imperialism.

The founding of Nanjing National Government broke the cross-strait civil war for ten years.

The establishment of a pseudo-government by the capitulators represented by Wang Ching-wei shows the division between the capitulators and the main war factions within the Kuomintang.

6 marks the victory of the new-democratic revolution.
