As a young man, Wu Qi spent a formative three years as a student of Confucianism. After gaining several years of administrative experience, he came to believe that, in order for benevolence and righteousness to survive in his time, military strength and preparation were necessary. Without a strong military to defend the just, he believed that Confucian virtues would disappear, and evil would dominate the world. Because of his emphasis on the importance of the military for safeguarding civil rights and liberty, the author of the "Wuzi" states that commanders must be selected carefully, ideally from those possessing courage and who excelled in military arts, but who also possessed good civil administration skills, and who displayed Confucian virtues, particularly those of wisdom and self-control.
