知己知彼 is a Chinese idiom (chengyu) meaning “to know yourself and your adversary”. To have a thorough understanding of both sides; to be fully aware of one's own strengths and weaknesses as well as those of one's opponent. Literally, “Know yourself, know your enemy”.
During the Spring and Autumn period, the military strategist Sun Wu authored 'The Art of War'. He believed that the supreme art of war was to subdue the enemy without fighting, compelling them to surrender intact, while direct military confrontation was a lesser approach.
One must be skilled in using stratagem to conquer without battle, and at the same time, 'know oneself and know the enemy' to ensure victory without defeat. Winning every battle is not the height of skill; the highest wisdom lies in subduing the enemy without any engagement.
