Wei Liaozi — Weighing the Battle尉繚子 戰權
Wujing Qishu (The Seven Military Classics) — the six besides the Sunzi Weiliaozi The six that remain when the Art of War of Sunzi is taken out of the seven military books the Song set as the texts for examining military officers. The Six Secret Teachings is sixty chapters of questions and answers in which King Wen and King Wu ask Taigong Wang, running from the governing of a state to chariots, cavalry, battle in the open and the crossing of water; the Three Strategies is three short books said to have been given to Zhang Liang by Huang Shigong; the Wei Liaozi is twenty-four chapters setting down in detail the military orders and the squads of five and ten around the time of Qin; the Wuzi is six chapters of Wu Qi's answers to Marquis Wu of Wei; the Methods of the Sima is five chapters handing down the military rites of before the Spring and Autumn period; and Questions and Replies with Li Weigong is three books in which Taizong of Tang and Li Jing go back and forth over the unorthodox and the orthodox, the empty and the full, the frontier peoples and the Han, and attack and defense. "Arms are an instrument of ill omen," "bring the enemy to you and do not be brought to him," and "a thousand chapters and ten thousand phrases do not go beyond that one phrase" all come from here. The remaining six streams of the military school, read after the Art of War, are gathered in one place.
1A thousand men make power, ten thousand make force
兵法曰:「千人而成權,萬人而成武。權先加人者,敵不力交;武先加人者,敵無威接。」故兵貴先勝於此,則勝彼矣;弗勝於此,則弗勝彼矣。凡我往則彼來,彼來則我往,相為勝敗,此戰之理然也。
The art of war says, "With a thousand men power is made; with ten thousand men force is made. He who lays his power on another first meets no strong grappling from the enemy; he who lays his force on another first meets no awe from the enemy." So troops hold it precious to win here first: win here, and you win there; fail to win here, and you do not win there. When we go out the other side comes, and when the other side comes we go out, and each is by turns the winner and the loser. Such is the reason of battle.
