What was the life of Sun Wu, a military thinker in the late Spring and Autumn period?

Sun Wu's military thought mainly includes the following aspects:

Flexibility: Sun Wu believes that the most important thing in war is to be flexible, and the side that is good at change will have an advantage. He stressed the unpredictable nature of war, which requires changes in tactics, organization, and the use of force at any time according to specific circumstances in order to achieve victory in war.

Purpose of war: Sun Wu believed that the purpose of war was to achieve political goals, not to undermine the enemy's military power. Therefore, he put forward the idea of "controlling the enemy without fighting", that is, using strategic and tactical means to contain the contract and force the enemy to achieve political goals.

Strategy in War: Sun Wu's book of war, The Art of War, emphasizes the importance of strategy and believes that strategy is the key to victory in war. He put forward the idea of "attacking the enemy by surprise and taking it by surprise", that is, attacking the enemy by taking advantage of the enemy's weakness by means of surprise and victory.

Use of force: Sun Wu believes that the use of force should be used flexibly according to specific situations, rather than rigidly applying certain rules. He put forward the idea that "soldiers are impermanent, and water is impermanent," that is, different methods of using troops should be adopted in different situations to achieve the best results.

Unified Command: Sun Wu believed that unified command was the key to victory in war. He advocated that the army should be under the overall command of a single military commander, rather than by multiple people.

In terms of command, Sun Wu emphasized that the army should remain mobile and be able to change formations as the lead rotes, so as to win the war.

Generally speaking, Sun Wu's military thinking emphasized flexibility and adaptability, war objectives, strategy, use of troops, and unified command.

Sun Wu emphasized that the victory or defeat of the war does not depend on the ghosts and gods, but is related to political clarity, economic development, diplomatic efforts, military strength, and natural conditions. Sun Wu not only believed that the world was an objective obstacle, but also believed that everything in the world was constantly moving and changing, and stressed that in war, we should actively create conditions to give full play to people's subjective initiative and promote the transformation of opposites in a direction favorable to oneself.

Sun Tzu's main military ideas in the Art of War are: 1. The idea of winning without a fight, opposing rash wars; Second, the idea of winning by surprise; Third, the idea of foolish soldiers, Sun Wu asked the generals to "make the ears and eyes of foolish soldiers ignorant", "make them profitable, do not sue them for harm", so that they can command the battle as they wish; Fourth, the top and bottom are united, the officers and soldiers are unanimous, and he also pointed out: "The Taoist, let the people bury the spring with the superiors, so that the forest can be destroyed to die with it, and can live with it, without fear of danger"; Fifth, avoid the real and attack the false, he wrote in the book of war:

The image of the soldier is water, the shape of the water avoids the height and tends to go down, and the shape of the soldier avoids the real and hits the void"; Sixth, the idea of "nothing", Sun Wu vigorously preached the benefits of "invisible": "Therefore, the extreme of the form of the soldier is invisible; If it is invisible, it cannot be peeped into the depths, and the wise cannot plan", he believes: "Those who are good at defending are hidden under the nine earths, and those who are good at attacking are moving above the nine heavens, so they can protect themselves and win all."

7. Insight into opportunities, "The Art of War" also has a similar discussion in this regard: "Seeing is better than what everyone knows, and neither is the good who is not good; Victory and the world is said to be good, and the good who is not good is also good". This embodies the Taoist military idea of using soldiers with wonder.

8. Strike later, he wrote in the "Military Struggle": "Those who are in difficulty in military struggle should take detours as straightness and hardships as benefits. Therefore, the detour and the temptation to benefit, the descendants of the people, the ancestors to, this knows the right plan.

We should make full use of all kinds of constraints and all kinds of illusions to contain and confuse the enemy, so that the enemy will fall into a situation of being passively beaten in the rapidly changing battle situation.
