Sun Tzu's Art of War was born in the Spring and Autumn Period 2500 years ago. Yu Fan said that the war at that time paid great attention to honesty, propriety and righteousness, which was illustrated by historical materials such as Rites and Music Conquering from the Son of Heaven, No Mourning, No Drum, No Column, etc. However, under such a social background, Sun Tzu issued the voice that "soldiers are also cunning". In the long history, Sun Tzu's Art of War is famous for its great practicability, which is highly praised by later generations and is still studied by experts and scholars from all over the world. Yu Fan said: "Sun Tzu's Art of War is a complete system, which embodies the wisdom of the East and the essence of China culture."
Yu Fan pointed out that Sun Tzu's Art of War embodies the ideas of "emphasizing war", "being cautious about war" and "preparing for war" everywhere. "Heavy fighting" means paying attention to war. Although war is hated by the world, Lao Tzu once said, "Soldiers are nameless weapons." However, war is inevitable, and it is often regarded as a turning point of social progress to promote the development of history. But for the country, the outcome of the war is related to the survival of the country, so "heavy fighting" has become a necessary move.
"The Art of War" said: "A wise monarch should be cautious and a good general should be alert. This is also the way to secure the country and the strategy of the whole army." As the head of a country, you can't form an army because of a moment's anger, nor can a general wage war because of a moment's anger. National subjugation cannot be restored, and the dead cannot be resurrected. Therefore, "careful war" is also very important. Yu Fan cited an example of modern war: 1982, Argentine President Gartieri rashly launched a war in an attempt to occupy the Malvinas Islands, which was defeated by Britain, making Argentina lose the right to negotiate with Britain to land on the island, and at the same time brought economic losses to Argentina, and Gartieri himself was jailed for it. It can be seen that "careful war" is indeed a wise move.
In addition, attention and caution to the war is not enough, which cannot guarantee that it will not be attacked or involved in the war. Yu Fan stressed: "Preparing for war is not for fighting, nor for fighting, but for self-protection, which is a means to promote peace."
Regarding the idea of "know yourself and know yourself" in Sun Tzu's Art of War, Yu Fan explained that before the war, knowing yourself and know yourself was like gambling, and the number of winners and losers was unpredictable; If you don't know yourself and yourself, you can't make reasonable strategies according to your current situation; If you don't know yourself or each other, it's like a blind man riding a blind horse, and the ending is self-evident. Therefore, before a battle, we must know ourselves and know ourselves.
