Only a nation that has created glory can understand the meaning of rejuvenation; Only a nation that has endured hardship has a deep desire for revival.

China is a big country with a history of more than 5,000 years of civilization and has been at the forefront of the world for a long time in history.

Among the four ancient civilizations in the world, only the Chinese civilization has a national history that has been passed down to this day. The four great inventions of ancient China have benefited the whole world.

Before the 16th century, there were about 300 major scientific and technological inventions that affected human life, of which 175 were inventions made by Chinese.

The Englishman Joseph Needham wrote in "The History of Science and Technology in China",

"More than 10 centuries before the advent of modern science and technology, China's accumulation of science and technology and knowledge was far superior to that of the West."

In the history of China, the rule of Wenjing, the rule of Zhenguan, and the prosperous era of Kangqian have successively appeared, demonstrating the prosperity of economic and cultural development and the broad wisdom of China's social governance.

Since modern times, due to the invasion of Western powers and the corruption of feudal rule, China has gradually become a semi-colonial and semi-feudal society.

However, the Chinese people did not give in, but stood up and struggled, carried out one magnificent struggle after another, and composed an epic song that can be sung and wept.

In the nearly 80 years from the Opium War to the May Fourth Movement, all classes, strata and political forces in Chinese society have stepped onto the stage of history in an effort to save China from peril.

Whether it was the Taiping Rebellion, the Wuxu Rebellion, or the Boxer Rebellion, they all ended in failure.

Although the Xinhai Revolution led by Sun Yat-sen overthrew the feudal imperial system that lasted for more than 2,000 years and established a bourgeois republic in China, it did not change the social nature of old China and the tragic fate of the people.

The history of modern China shows that neither the old-style peasant revolution nor the weak bourgeois revolution can accomplish the historical task of saving the Chinese nation and fighting imperialism and feudalism, still less can it undertake the historical mission of realizing national rejuvenation.

At the beginning of the 20th century, bourgeois party politics emerged in China, with more than 300 large and small political parties and political groups appearing in Beijing, Shanghai and other places, but they soon disappeared from the Chinese political scene.

The fundamental reason for their failure lies in the fact that they have not been guided by scientific theories, have not had advanced classes as a foundation, have failed to put forward a correct program and mobilize the masses of the people to solve the urgent problems facing Chinese society in modern times, and have not won the support of the broad masses of the people.

Therefore, their failure has become a historical inevitability. Again and again, the Chinese nation has struggled again and again, and the road of the Chinese nation to pursue its dreams has been difficult and tortuous.

In order to achieve national rejuvenation, hundreds of millions of people have been haunted by dreams, generations have been seeking from top to bottom, and the Chinese people who have fought bravely and unyieldingly have struggled forward in the dark.
