Art of War 4.19

Literally, “a victorious army is like an 鎰 i (20 oz.) weighed against a 銖 shu (⁠1/24⁠ oz.); a routed army as a shu weighed against an i.” The point is simply the enormous advantage which a disciplined force, flushed with victory, has over one demoralised by defeat. Legge, in his note on Mencius, I. 2. ix. 2, makes the 鎰 to be 24 Chinese ounces, and corrects Chu Hsi’s statement that it equalled 20 oz. only. But Li Ch‘üan of the T‘ang dynasty here gives the same figure as Chu Hsi.
