From the Opium War to the May 4th Movement systematically narrates the major historical events from the Opium War to the May 4th Movement, summarizes the heroic struggle of the people of China against foreign invaders and domestic traitors, and attaches great importance to singing the patriotic spirit of the Chinese nation. The basic structure of From the Opium War to the May 4th Movement revolves around three revolutionary climaxes in China's modern history: the Taiping Heavenly Kingdom, the Boxer Movement and the Revolution of 1911. The author doesn't agree to take "Westernization Movement-the Reform Movement of 1898-the Revolution of 1911" as the clue of the historical progress trend in this period, but insists on discussing the modern history of China with the Taiping Heavenly Kingdom, the Boxer Movement and the Revolution of 1911 as the main body. The author thinks that during the Taiping Heavenly Kingdom, the Boxer Rebellion and the Revolution of 1911, there were large-scale peasant resistance struggles all over the country. It is these peasant-dominated resistance struggles of the people of China that pushed China's national democratic revolution to a climax and dealt a heavy blow to domestic and foreign enemies. The author believes that even in the historical drama of the Reform Movement of 1898, which was staged at the upper level of society, "the real protagonist of history is actually neither the reformists headed by Kang Youwei, nor the Empress Dowager Cixi or Emperor Guangxu, but hundreds of millions of poor working people who were exploited and oppressed and struggled for survival, mainly the peasant masses." From the Opium War to the May 4th Movement, specific historical events were always analyzed around the concept of patriotism. Commenting on the religious color of the Taiping Heavenly Kingdom, the author pointed out that the establishment of worship shrine "was not that Christianity captured Hong Xiuquan and influenced the revolutionary peasants in China, but that Hong Xiuquan used some forms of Christianity according to the needs of the peasant revolution in China ... so that the peasant revolution in China achieved a novel form under the heavy pressure of feudalism." Although religious superstition was their weakness, it played a role in inspiring and organizing the masses at that time. The historical facts listed in this book show that the heroes of the Taiping Heavenly Kingdom did not give up their patriotic stance or paralyze their fighting spirit because foreign invaders believed in the same god, which is in sharp contrast with the foreign servility of the Qing government. They resolutely refused to recognize the unequal treaties, insisted on banning opium, and finally "the realistic struggle forced revolutionary peasants to break through the fog of religion and carry out arduous struggles with all United internal and external enemies", which showed the true nature of peasant revolutionaries and the patriotic spirit of China people. As for the Boxer Rebellion, the author did not criticize it because it was poisoned by feudalism and xenophobia, but closely combined with the internal and external situation at that time, passionately described the heroic struggle of the Boxer Rebellion against the invaders, fully affirmed the historical role of the Boxer Rebellion in preventing imperialism from dividing up China, and was the pioneer of the rising anti-imperialist and anti-feudal struggle of the people of China. The Boxer Movement showed that in semi-colonial and semi-feudal China, the broad masses of peasants were not only powerful forces against feudal forces, but also powerful forces against imperialism. This book makes a pertinent evaluation of the national bourgeoisie's exploration of saving the country and the people. The author thinks that the Reform Movement of 1898 was basically a patriotic movement. Although the reformists were hostile to the peasant revolution and only advocated improvement, they played the banner of saving the country in the face of the crisis that imperialism carved up China at that time. Their cry for the national crisis and their vigorous propaganda for the reform proposition "aroused the patriotic enthusiasm of the masses, so that the political reform movement they launched became a mass patriotic movement." This book also gave the bourgeois revolutionaries headed by Sun Yat-sen their due historical position, highly praised the heroic dedication of Sun Yat-sen and his comrades and their relatively complete democratic revolutionary program, and described the bourgeois patriotic movement in detail, pointing out that under the conditions at that time, "it embodied the common desire and democratic rights of the people of China. The Revolution of 1911 overthrew the rule of the Qing Dynasty and dealt a blow to imperialism standing behind it. Although the Revolution of 1911 failed, it "indicates that the revolutionary struggle of China people against imperialism and feudalism will enter a new stage and continue at a higher level". While warmly praising the patriotic struggle of the people of China, the author lashed the ugly people trapped in from the mire, the Chinese nation. When we read the tragic ending of the Opium War, the heroic defeat of the Taiping Heavenly Kingdom, Eight-Nation Alliance's heinous crimes and the farce of foreigners "representing China" in foreign countries, we aroused strong indignation against the aggressors and traitors. The author doesn't have much pen and ink, and the clear love and hate condensed on the pen tip gives readers a strong infection and profound lessons. Three revolutionary climaxes all failed miserably, and China was still struggling in the semi-colonial and semi-feudal abyss. History has raised such a serious question to us: Where is the way out for China? How can we save China? From the Opium War to the May 4th Movement, a large number of historical facts eloquently show that it is impossible for the peasant revolution to establish a new system to replace the old order; The bourgeois revolution in China cannot overthrow the rule of imperialism and feudalism. The history from the Opium War to the May 4th Movement draws the following conclusions: the revolution can only be won under the leadership of the proletariat; Only by establishing a socialist system can China be saved! This makes us further realize that a true patriot should be a supporter of the socialist system and the leadership of the party.
