Writing Balance Rule: The left component (疒 variant or similar radical root 𠂉/啇 structure) must be balanced with the right component 攴 (shū / hitting hand), ensuring neither side crushes the other; keep the vertical center balanced.
Simplification Logic: The traditional form 敵 uses 啇 on the right, which was streamlined in the simplified form 敌 by maintaining structural balance while reducing complexity.
Know the enemy and know yourself, and you can fight a hundred battles without danger of defeat.
他们是势均力敌的对手。
tā men shì shì jūn lì dí de duì shǒu.
They are evenly matched opponents.

5. History
Liushu category: Phono-semantic (形声)
Origin: Originally combined a phonetic base indicating a base or root sound with the action radical of a hand holding a weapon or striking tool, signifying combatants locked in rivalry or enmity.
Semantic Evolution: Shifted from the physical act of opposing or fighting an antagonist in ancient battle contexts to modern meanings encompassing enemies, competitors, and mathematical equals (matches).
Found extensively in classical military texts such as Sun Tzu's Art of War.
