Sun Wu was an ancient military scientist in China, the founder of ancient military science in China, and a general of Wu at the end of the Spring and Autumn Period. His real name is Changqing, and he is from Qi Le 'an (now Boxing North, Shandong Province). Date of birth is unknown, from the end of 6th century BC to the beginning of 5th century BC.

Due to the civil strife in Qi, Sun Wu left the State of Wu, and under the recommendation of important officials of the State of Wu, he submitted thirteen articles of Sun Tzu's Art of War to He Lv, the king of Wu, and was reused as a general. Wu Chu has been fighting for hegemony in Jianghuai area for a long time. Sun Wu and Wu Yuan assisted He Lv in formulating the strategy of attacking Chu, which exhausted Chu's national strength. The Art of War, written by Sun Tzu, summarizes the war experience in the late Spring and Autumn Period and before. For the first time in the military history of China and the world, the overall situation of the war was systematically dealt with.
