After the founding of New China, the mental outlook of the people in China has undergone fundamental changes. After ending the long history of war and bullying, China people's national pride and self-improvement cultural blood were completely awakened from their deep sleep. As the saying goes, "building and defending the motherland" has become the fundamental belief of most China people; At that time, the international environment was full of dangers for new China, and it was under the pressure of the huge national defense crisis that the patriotic enthusiasm of the people of China was increasingly stimulated. Whether ordinary workers, farmers, soldiers or senior intellectuals studying abroad, they all regard "serving the motherland" as their glory and ideal.

It is against this historical background that the people of China miraculously developed a large number of national defense achievements marked by "two bombs and one satellite" under extremely difficult material conditions, which made the international community sit up and take notice. It can be said that this is the cry of an ancient nation with excellent cultural blood in the process of suffering, gradual awakening and re-emergence, and it is also the source of strength and the fundamental reason for its achievements.
