"Know yourself and know your enemy" originates from The Art of War: Attack by Stratagem, where the original text reads, "Know the enemy and know yourself, and you can fight a hundred battles without danger." It means that by understanding both oneself and the opponent, one can avoid peril in numerous battles. The core of this idiom lies in emphasizing the importance of information symmetry and comprehensive cognition, and it applies not only to the military domain but also widely to business competition, negotiation, interpersonal communication, sports competition, and other scenarios. It reminds people that before making decisions, they should objectively assess their own strength, advantages, and shortcomings, and also gain deep insight into the other party's situation, intentions, and weaknesses, so as to formulate effective strategies. In emotional coloring, it is relatively neutral, often carrying a commendatory or admonitory sense, reflecting rationality, wisdom, and strategy. In cultural background, it reflects the wisdom of "prudent warfare" and "victory before battle" in traditional Chinese military thought, and remains an important principle of strategic thinking to this day.
