I. Firm determination to safeguard national security

Since ancient times, the people of China have always attached great importance to national security. Whether it is the contention of a hundred schools of thought during the Warring States Period or the resistance to foreign invasion in modern times, the people of China have shown their determination to resolutely safeguard national security. This determination is embodied in the spirit of not being afraid of sacrifice and going forward bravely. It tells us that national security is the responsibility of everyone in China, and only firm determination can resolve the crisis and protect our homeland.

Second, pay attention to the construction of comprehensive strength

An important revelation in China's national defense history is to pay attention to the construction of comprehensive strength. China's ancient military system attached great importance to the balanced development of various forces, and paid full attention to forces, weapons and equipment. This kind of construction that pays attention to all-round strength can make the country have stronger combat effectiveness and win the war.

This revelation also applies to modern national defense construction. Pay attention to improving the overall strength of the army and constantly innovate and strengthen in all aspects.

Third, actively adopt flexible strategies.

China's strategic choice in the history of national defense attaches great importance to flexibility. Ancient military strategists in China were good at finding the weak links of the enemy and actively adopted flexible strategies, thus achieving many important victories under the condition of relatively unequal strength. This revelation tells us that in modern warfare, flexible tactics and strategic choices are very important, which can better adapt to the ever-changing battlefield environment and maintain the initiative in combat.

Fourth, strengthen the integration of national defense and civilian technology.

Another important revelation in China's national defense history is to strengthen the integration of national defense and civilian technology. In ancient China, there was a close relationship between the army and the people. The army engaged in agricultural production and engineering construction in peacetime, which improved its own quality and military strength. These modes of military-civilian integration have strengthened the overall strength of the country and improved the country's ability to resist.

In modern society, the integration of national defense and civil technology is becoming more and more important. We should maintain close military-civilian relations and make contributions to national security and development.

Verb (abbreviation for verb) respects peace and cooperation.

One of the most valuable revelations in China's national defense history is to respect peace and cooperation. The people of China are well aware of the destructiveness and cruelty of war, so they have always advocated peace and cooperation. China's ancient cultural tradition emphasizes peace and harmony, and this concept also runs through China's national defense construction. We should promote development and prosperity and safeguard world peace and stability through international exchanges and cooperation.

These revelations have important guiding significance for us to understand the importance of national security and strengthen national defense construction. We should inherit and carry forward the traditional wisdom and courage of the Chinese nation, firmly safeguard national security, pay attention to the construction of comprehensive strength, actively adopt flexible strategies, strengthen the integration of national defense and civilian technology, respect peace and cooperation, and make unremitting efforts to achieve national prosperity and stability.
