体育比分预测竞猜网站 www.010514.live Sun Wu (535 B. C.~480 B. C.), whose courtesy name was Changqing, was born at Le'an (now Huimin，Shandong Province).
Revered as "Sun Zi", he was a well-known military strategist in late Spring and Autumn Period. To escape from domestic chaos, he took refuge in the State of Wu, where he was appointed general by the king. Under his command, the forces of Wu defeated the strong army of the State of Chu, subdued the people of the State of Yue, and deterred the states of Qi and Wei.
Sun Wu's The Art of War, composed of 13 articles, was the first systematic book on military strategies and tactics in ancient China and one of the earliest works on military strategies and tactics in the world.
In his theories, the art of war lies in the strategies of conquering the enemy. He held that five factors are of pivotal importance in the military affairs, that is, dao ( the moral law ), tian (heaven), di (earth), jiang (the commander)，and fa (method and discipline).
Dao refers to political strategies, which require the monarch and his people to make concerted efforts to support the war.
Tian and di refer to the natural conditions in warfare.
Jiang refers to the qualities of the military commander，in which “zhi (wit), xin (credibility), ren (benevolence), yong(courage), yan (strictness)” are a must.
Fa refers to the relevant rules and regulations during warfare. Decrees must be issued and the systems of penalties and rewards must be applied to reinforce these rules and regulations and to heighten morale.
In The Art of War, Sun Wu elaborated on his strategic principles, which include ample preparations before war, better manoeuvrability over the adversaries, go-ahead offensive tactics, mobile and allied warfare, secret operations and flexible commanding without always obeying the sovereign's decrees.
The Art of War is rich in dialect thoughts, an example of which is Sun Zi's suggestion that the interactions among climatic, geographical and human factors are pivotal in combats. Also of pivotal importance are the quick and flexible reactions to complicated situations, on which Sun Zi pointed out that " he who can modify his tactics in relation to his opponent and thereby succeed in winning, may be called a heaven-born captain".
His assertion that "all warfare is based on deception" reveals his perception of the special nature of strategics as an art.
