Economy is the material foundation of national defense, so Qiang Bing must get rich first. As early as the Spring and Autumn Period and the Warring States Period, some famous politicians and military strategists had the idea of strengthening the army, and the first thing was to enrich the country. In general, economic development should take precedence over national defense development, because rich countries can make Qiang Bing, and its strong economic strength is the material basis for army building and national defense construction.

2. National defense construction and national political situation interact with each other.

From the whole history of China, the early national defense has been growing. From the Spring and Autumn Period and the Warring States Period to the Qin and Han Dynasties until the prosperous Tang Dynasty, the national defense of the Central Plains Dynasty generally showed an upward trend, even reaching its peak in the prosperous Tang Dynasty. However, after the end of the Tang Dynasty, national defense declined gradually, especially in the Southern Song Dynasty, the Ming Dynasty and the Qing Dynasty, which can be said to be on the verge of collapse.

This shows that when the ruling class is in the rising stage, the national defense may be strong when the political civilization and the country are unified, but when the ruling class declines, the political corruption and the country is divided, the national defense will weaken or even collapse. To strengthen national defense construction, we must attach importance to and solve the problems in the political life of the country and constantly maintain the vitality and vitality of the state power.

3. Strengthening the army is an important task of national defense construction.

Throughout the ages, the army has always been an important part of national defense construction, and building a well-trained, well-managed and effective army is the fundamental problem of national defense construction.

4. Weapons and equipment are an important factor in determining national defense strength.

The history of China's national defense tells people that weapons and equipment, as well as arms tactics decided by them, have an important influence on the outcome of the war and national defense strength. When Song Taizu Zhao Kuangyin was in power, he personally inspected the quality and performance of new weapons every ten days, which shows that the rulers at that time attached great importance to the construction of weapons and equipment.

5. National defense construction must be continuously strengthened in the reform.

Combat readiness is the core content of national defense construction. With the progress of society and science and technology, the development and change of war will inevitably lead to the development and change of national defense construction. In the historical practice of China's national defense construction, there have been many reforms in the field of national defense. Reform runs through the whole process of national defense history.

Whether initiated or enforced, reform is always an inevitable requirement of national defense development. We can't move forward without reform. The more thorough the reform, the more promising the national defense will be.
