What is the traditional concept of security?

"Traditional security concept", that is, "traditional national security concept", refers to various security ideas and viewpoints in a long historical period, which can be said to be the period from the existence of the country to the end of the Cold War. It includes not only the security concepts in various national theories and international relations theories since modern times, especially since modern times, such as the security concepts in idealism theory and realism theory, but also various ancient national security concepts, such as those in China's ancient Confucianism, Taoism, France and military strategists, those in the national theories of ancient Greek thinkers such as Plato and Aristotle, and those in Sun Tzu's Art of War. For example, I ching wrote: Confucius said: "people in danger are also in their places." The dead, let them live. Chaos, but also cure. Therefore, you are safe without forgetting danger, not forgetting death, not forgetting chaos. It is safe for the body and the country can be protected. Yi said:' Death is death. It depends on bud mulberry. "That is to say, Confucius once said," Because you think it is safe, you are in danger, because you think it can be preserved for a long time, you are born and died, and because you think it is political and peaceful. Therefore, a gentleman is safe without forgetting danger, keeps without forgetting extinction, and is peaceful without forgetting chaos, so his life is safe and the country can be preserved. Yi said:' Always worry about death, and if you want to die, the country will be like a mulberry.' This expresses the safety concept of China traditional culture "be prepared for danger in times of peace".
