Reason: The failure of the anti-aggression struggle was first determined by the corrupt social system in China's semi-colonial and semi-feudal society. Secondly, the backwardness of the national economy, especially the backwardness of economic technology and combat capability.

Lesson: If you lag behind, you will be beaten, but fundamentally speaking, it is impossible to mobilize and organize the people to wage a victorious anti-aggression war without overthrowing the corrupt social system in China's semi-colonial and semi-feudal society.

Reason: The failure of the anti-aggression struggle was first determined by the corrupt social system in China's semi-colonial and semi-feudal society. Secondly, the backwardness of the national economy, especially the backwardness of economic technology and combat capability.

The fundamental reason for China's failure in previous anti-aggression wars lies not in the backwardness of economy and technology, but in the reactionary decay of the ruling clique. The problems of "peace" and "war" should be analyzed in detail. But in the case of large-scale foreign invasion, "peace between the Lord and the country" is actually surrender and betrayal. Saying "peace" is "wisdom" and "patriotism" is a misinterpretation of history. The spontaneous anti-imperialist struggle of China farmers in modern times took the form of universal exclusion, which was primitive and backward, but patriotic, just and progressive in nature. It is wrong to confuse the exclusion of them with the exclusion of feudal die-hards. Similarly, anti-xenophobia should also be analyzed in detail. There are both advanced figures who actively learn from the west and seek to save the country and strengthen themselves, and those who are willing to be enslaved by foreign powers and flatter should never be affirmed. The development of China's history proves that only through the anti-imperialist and anti-feudal new-democratic revolution led by the proletariat can China move towards socialism. The view that "learning from the West" is China's "only way out" is contrary to historical facts.

China closed its doors to the outside world from Emperor Jiaqing of the Qing Dynasty, which led to the failure of all previous anti-aggression wars in modern times.

Backwardness is bound to be beaten, turmoil will inevitably lead to backwardness, and only a powerful country can avoid foreign aggression. The corruption of the ruling government is the fundamental reason.

Lessons from the failure of China's modern anti-aggression war;

First, in modern China, to strive for national independence and national prosperity, we must change the semi-colonial and semi-feudal social system under the joint rule of imperialism and feudalism. The people of China must combine the national struggle against imperialism with the class struggle against feudalism in order to accomplish the task of modern China revolution.

Second, it is an eternal truth that backwardness will lead to beatings and compromise will lead to failure. It is not feasible to simply learn western technology. The Chinese nation should learn from the western political system and change the backward political system in China. Only national independence and people's liberation can overthrow the reactionary imperialist rule over China, carry out modernization and make the country truly strong.

The development of China's history proves that only through the anti-imperialist and anti-feudal new-democratic revolution led by the proletariat can China move towards socialism. The view that "learning from the West" is China's "only way out" is contrary to historical facts.
